History --------------- ### Changes in v3.2.0: - Sampling improvements: - Better performance (lower rendering time and faster convergence) - More pleasing blue noise enabled when the total number of frames to be accumulated is known in advance and set as the `targetFrames` parameter at the framebuffer - Note a maximum of 64k samples is supported - Improved `denoiser` image operation: - User-controlled quality levels via parameter `quality` - Optionally denoise alpha channel as well, enabled via parameter `denoiseAlpha` - Support half-precision (16\ bit float) texture formats `OSP_TEXTURE_[RGBA16F|RGB16F|RA16F|R16F]` and two-channel 32\ bit float textures `OSP_TEXTURE_RA32F` - New parameter `limitIndirectLightSamples` for the `pathtracer` which limits the number of light samples after the first non-specular (i.e., diffuse and glossy) bounce to at most one - Implement MIP Mapping for better texture filtering. If the additional memory per texture needed cannot be spared, applications can disable the generation of MIP maps with device parameter `disableMipMapGeneration` - The backplate (background texture) is now always sampled at the pixel center and thus not blurred by the pixel filter anymore - Avoid color bleeding across eye-subimages when stereo rendering - Superbuild uses binary packages of Open VKL - Removed Intel ISPCRT dependency (ISPC compiler is still needed): - oneAPI Level Zero Loader is no longer necessary - `zeContext` and `zeDevice`device parameters are no longer supported - `ispcrtContext` and `ispcrtDevice`device parameters are no longer supported - Clarify the size of `OSP_BOOL` to be 1 byte - Fix artifacts occasionally appearing with `gpu` device - The new minimum versions of dependencies: - Embree v4.3.3 (better error reporting) - Open Image Denoise v2.3 (better image quality with `HIGH` quality mode, added `FAST` quality mode) - rkcommon v1.14.0 ### Changes in v3.1.0: - Principled and Luminous materials support emissive textures - Add native support for disc and oriented disc geometry - Add support for mirror repeat and clamp to edge texture wrap modes - GPU device now also supports motion blur - Improve noise in reflections of ThinGlass - Improve adaptive accumulation: working with GPU, fix correlations - Fix indirectly seen albedo and normal buffer - Fix artifacts when using specular texture for Principled - Fixes for PixelFilter - Parameter was ignored (always using the default Gaussian) - Avoid a shift/misalignment within the pixel for first sample - Fix empty image on Windows when `focusDistance=0` - Fix missing SDK headers for `ISPCDevice*` - The new minimum versions of dependencies: - Embree v4.3.1 - Open VKL v2.0.1 - Open Image Denoise v2.2 (better quality with fine details, support AArch64 CPU on Linux) - ISPCRT v1.23.0 (uses environment variable `ISPCRT_GPU_DRIVER` to select GPU to run on when multiple (i)GPUs are present) - rkcommon v1.13.0 (fixes crash using GPU and emissive geometry) ### Changes in v3.0.0: - Beta support for Intel Xe GPUs (Intel Arcâ„¢ GPUs a Intel Data Center GPU Flex and Max Series), exploiting ray tracing hardware support. Implementation is based on the [SYCL](https://www.khronos.org/sycl/) cross-platform programming language implemented by [Intel oneAPI Data Parallel C++ (DPC++)](https://www.intel.com/content/www/us/en/developer/tools/oneapi/data-parallel-c-plus-plus.html). Note that the following features are not implemented yet or are not working correctly on the new `gpu` device: - Multiple volumes in the scene - Clipping - Motion blur - Subdivision surfaces - Progress reporting via `ospGetProgress` or canceling the frame via `ospCancel` - Picking via `ospPick` - Adaptive accumulation via `OSP_FB_VARIANCE` and `varianceThreshold` - Framebuffer channels `OSP_FB_ID_*` (id buffers) - Experimental support for shared device-only data, works only for `structuredRegular` volume - Further known issues - Some delay on start-up or when changing the scene, because kernel code is JIT compiled and specialized. JIT compilation can be cached by setting environment variable `SYCL_CACHE_PERSISTENT=1`, then consecutive starts or rendering the same scene configuration is without delay - For some combination of compiler, GPU driver and scene the rendered images might show artifacts (e.g., vertical lines or small blocks) - Multidevice does not support `OSPImageOperation`s for denoising or tone mapping - Add implicit indexing for `mesh` geometry - Add support for transferring ownership of temporary buffers: `ospNewSharedData` accepts an optional deleter callback - Optimizations for MPI module, supported by new integrated performance tracing framework - Optimize `scivis` gradient shading - Main thread does not set FTZ/DAZ anymore for denormals handling - Compute intersection epsilon for Mesh to avoid rendering artifacts due to self-intersection - Fix energy conservation of Pricipled material under certain parameter combinations - Fix `denoiser` to not wipe the alpha channel - Fix crash in HDRI light - Fix link order for Debug build on Windows - The new minimum versions of dependencies: - Embree v4.3.0 - Open VKL v2.0.0 - Open Image Denoise v2.1.0 - ISPC v1.21.1 - rkcommon v1.12.0 - Breaking API changes - Renamed `OSP_TEXTURE_FILTER_BILINEAR` to `OSP_TEXTURE_FILTER_LINEAR ` and `OSP_VOLUME_FILTER_TRI[LINEAR|CUBIC]` to `OSP_VOLUME_FILTER_[LINEAR|CUBIC]` - Most enums now use storage type `uint32` - `gridSpacing` of spherical regular volume defaults to full sphere - Remove deprecated parameters and API calls - error callback signatures without user pointer - first argument of `ospNewMaterial` - module name `ispc`; use `cpu` - `volume` texture and `isosurface` geometry: `volumetricModel`; use `OSPVolume volume` - Transfer function `vec2f valueRange`; use `box1f value` - `hdri` and `sun-sky` lights: `intensityQuantity` `OSP_INTENSITY_QUANTITY_RADIANCE` - `spot` light with `intensityDistribution`: `intensityQuantity` other than `OSP_INTENSITY_QUANTITY_SCALE` ### Changes in v2.12.0: - Support denoising on the GPU with OIDN 2.0, which is the new minimum version. The `denoiser` now uses HDR mode - New parameter `maxScatteringEvents` for the `pathtracer` which limits the number of non-specular (i.e., diffuse and glossy) bounces - Optimized dynamic load balancing for MPI devices - Fix crash when using small image resolution and many MPI ranks - Fix crash in `pathtracer` when `lightSamples > 0` but there are lights in the scene - Fix transparent shadows with too high `minContribution` setting - The new minimum version for ISPC is v1.20.0 - Release binaries on Linux are built on Rocky 8 ### Changes in v2.11.0: - Support single ISPC target on Windows - OSPRay's superbuild can now be provided a CMake toolchain file for cross-compilation - Add support for double pumped NEON instruction on ARM64 - Reduce the memory overhead of the `mpiOffload` device and resolve memory and `MPI_Comm` handle leaks - Support for volume rendering (and thus the dependency to Open VKL) can now be compile-time controlled via CMake variable `OSPRAY_ENABLE_VOLUMES` - OSPRay's MPI modules have been split up and renamed, the `mpiOffload` device is now in the `mpi_offload` module, while the `mpiDistributed` device is now in the `mpi_distributed_cpu` module - Add native support for spheres via Embree, which requires the positions and radius of the spheres to be interleaved in memory; if this is not the case, OSPRay will internally create a copy of the data - Fix `dynamicScene` flag on World and Group to influence BVH quality again: default is now "high", which should improve rendering performance, depending on the scene; and "low" when `dynamicScene` is enabled (improving BVH build performance) - Fix a crash in `pathtracer` when there are no lights - Fix a data corruption bug when setting string parameters for objects in the `mpiOffload` device - Various documentation fixes - OSPRay now has a new dependency, which is ISPC Run Time (ISPCRT) in minimum 1.19.0 version - Adapt to Embree v4.0.0 API changes, which is thus the new minimum version; additionally, the new minimum version for Open VKL is v1.3.2 and for ISPC v1.19.0 - Removed support of MSVC14.0 (Visual Studio 2015) and the second generation Intel Xeon Phi processor (codename Knights Landing) ### Changes in v2.10.0: - Add support for primitive, object, and instance ID buffers as framebuffer channels - Support face-varying attributes for Mesh and Subdivision geometry - Replace CMake variable `OSPRAY_PIXELS_PER_JOB` by `OSPRAY_RENDER_TASK_SIZE`; variance tracking for adaptive accumulation is now per task instead of per tile, allowing for more granular adaptation - OSPRay now requires minimum Open VKL v1.3.0 to bring the following improvements: - VDB volumes added support for contiguous data layouts, which can provide improved performance (`nodesPackedDense`, `nodesPackedTile` parameters) - Particle volumes are more memory efficiency and improved performance - OSPRay now requires minimum ISPC v1.18.0 for Open VKL and to include a fix for parallel dispatch of uniform function pointers - MPI Offload: resolve object life time tracking issue that would result in framebuffer and data info being release too early, leading to a crash - Fix crash with OpenMPI due to argument handling - Fix clipping when rays are parallel to clipping planes - Fix missing SDK headers from CPU and MPI module - Deprecated the `vec2f valueRange` parameter of the `piecewiseLinear` transfer function, use `box1f value` instead ### Changes in v2.9.0: - Add support for multi-segment deformation motion blur for `mesh` geometry - OSPRay now requires minimum Open VKL v1.2.0 to bring the following improvements: - Structured regular volumes support for cell-centered data via the `cellCentered` parameter (vertex-centered remains the default) - Particle volumes ignore particles with zero radius - Add support for dynamic load balancing in MPI Offload device - Support for photometric lights (e.g., IES or EULUMDAT) also for `sphere` and `quad` lights. When setting `intensityDistribution`, other values for `intensityQuantity` than `OSP_INTENSITY_QUANTITY_SCALE` are deprecated - Changed CMake variables for enabling app categories: - `OSPRAY_ENABLE_APPS_BENCHMARK` replaces `OSPRAY_APPS_BENCHMARK` - `OSPRAY_ENABLE_APPS_EXAMPLES` replaces `OSPRAY_APPS_EXAMPLES` - `OSPRAY_ENABLE_APPS_TUTORIALS` replaces `OSPRAY_APPS_TUTORIALS` - `OSPRAY_ENABLE_APPS_TESTING` replaces `OSPRAY_APPS_TESTING` - Improve sampling of quad lights in the `pathtracer` (solid angle instead of area) - Instances can now have the group object rebound via a parameter - Fix leaking framebuffers in the MPI Offload device - Resolve possible race condition in assigning IDs to distributed objects in the MPI device - Move ISPC module to `modules/` folder and renamed the module to `cpu` - Minimum version of rkcommon is 1.9.0, which brings the following improvements: - Add detection of Intel oneAPI DPC++/C++ compiler - Fix memory leak ### Changes in v2.8.0: - Lights can be now part of `OSPGroup` and thus instanced like geometries and volumes and thus lights also support motion blur (with the path tracer) - Add cylinder light (with solid area sampling) - Add support for rolling shutter of cameras - Add support for quaternion motion blur for instance and camera to allow for smoothly interpolated rotations - Fix illumination from emissive quad meshes ### Changes in v2.7.1: - Use Open VKL v1.0.1 to fix sporadic slowdowns when rendering structured regular and VDB volumes with the SciVis renderer - Fix CMake variables and logic - Fix crash when `transferfunction.opacity = 0` - Fix bug in MPI data-parallel rendering that caused rendering to hang - Workaround dynamic linking issue on Windows in MPI distributed rendering - Correctly initialize `renderFrame` progress - Improved performance of data-parallel rendering for scenes with a large number of regions - Expanded camera model support of the data-parallel renderer, data-parallel rendering can now use all the camera models supported by the SciVis renderer - Clarify documentation and error messages ### Changes in v2.7.0: - Add support for transformation and camera motion blur (with the path tracer) via `shutter` parameter of the camera and `motion.transform` array and `time` parameter of the instance and camera - OSPRay can now be built for ARM64 CPUs with NEON (e.g., Apple M1) using the superbuild. Thus, new minimum versions are for ISPC 1.16.0, for Embree 3.13.1 and for rkcommon 1.7.0 - OSPRay now requires minimum Open VKL v1.0.0 to bring the following improvements: - Configurable `background` values for all volume types (default `NaN`), defining region outside the volume domain - Better default sampling rate for scaled VDB volumes, improved robustness - Structured regular volumes now support tricubic filtering and more accurate gradient computations as well as more robust isosurfaces - The multidevice module contains a new OSPRay device implementation that delegates work to any number of subdevices. This is an experimental feature in this release but we invite feedback - SciVis Renderer now ignores normal/albedo/depth hits on surfaces that are fully transmissive (material `d = 0`) - Changed the behavior of background rendering in SciVis renderer to more closely reflect that of the path tracer: Background hits are rendered in background color in the albedo buffer and black in the normal buffer - The SciVis renderer does not compute depth of field (DoF) anymore, as this effect does not align with the SciVis renderer definition and exposed artifacts - Fixed crash on exit when using the MPI device - Fixed rendering of depth buffer in the example application - The first argument to material constructor `ospNewMaterial`, i.e., `renderer_type`, is now deprecated and will be removed in a future release. AO and SciVis renderers still assume "obj" like behavior for all material types - Deprecated the `xfm` parameter of the instance, use `transform` instead - Dependencies Google Benchmark, GoggleTest, and Snappy moved out-of-source to superbuild ExternalProjects ### Changes in v2.6.0: - Added new `intensityQuantity` type `OSP_INTENSITY_QUANTITY_SCALE` for the `hdri` and `sunSky` light source. For the future this is the only supported quantity for these lights, the value `OSP_INTENSITY_QUANTITY_RADIANCE` is deprecated. When `OSP_INTENSITY_QUANTITY_SCALE` is used for `sunSky` the default value of `intensity` is `0.025` to match the old behavior - The MPI module is included in the releases packages. An [MPICH-ABI](https://www.mpich.org/abi/) compatible build is provided for Linux that can be run with the Intel oneAPI HPC Toolki, MPICH, and other MPICH-ABI compatible MPI distributions. The Windows release is built against MPI provided in the Intel oneAPI HPC Toolkit - OSPRay now requires minimum Open VKL v0.13.0 to bring the following improvements: - Support half precision float (fp16) voxel data in structured volumes (regular and spherical) and VDB volume - Supporting tricubic filtering via `VKL_FILTER_TRICUBIC` filter for VDB volume - Fixed artifacts for isosurfaces of unstructured volumes - Performance improvements for isosurfaces when multiple isovalues are selected - Better, adaptive sampling of AMR volumes - The `mpiOffload` and `mpiDistributed` devices now support picking. Picking in the distributed device will return the globally closest object on the rank that owns that object. Other ranks will report no hit - Messages issued from ISPC code use the same reporting path as the C++ code, thus now the whole OSPRay console output can be consistently filtered with log levels - Open VKL and Embree internal errors are now correctly mapped to their corresponding OSPRay errors - Fix behavior of committing the framebuffer in distributed rendering to match that of local rendering ### Changes in v2.5.0: - Add native support for cones or cylinders with curves geometry of type `OSP_DISJOINT`, requiring minimum version 3.12.0 of Embree - Replaced OSPRay's internal implementation of round linear curves by Embree's native implementation. Internal surfaces at joints are now correctly removed, leading to higher quality renderings with transparency, at the cost of intersection performance - SciVis renderer improvements: - Colored transparency, colored shadows - Light sources are visible including HDRI Light environment map - The MPI module is now distributed as part of OSPRay in the modules directory - The socket-based communication layer has been removed - Add `intensityQuantity` parameter to light sources to control the interpretation and conversion of the `intensity` into a radiative quantity - OSPRay now requires minimum Open VKL v0.12.0 to bring the following improvements: - Better default sampling rate for scaled volumes, improving performance - Higher robustness for axis-aligned rays - Removed limit on the number of volumes (both overlapped and separate) that a ray can intersect while rendering. Now it is limited by available memory only. - Move to OIDN v1.3.0 to bring the following improvements: - Improved denoising quality (sharpness of fine details, fewer noisy artifacts) - Slightly improved performance and lower memory consumption - Both geometric and volumetric models can now have their child geometry/volume objects rebound using an object parameter - Fix light leaking artifacts at poles of HDRI (and Sun-Sky) light - Add sRGB conversion to `ospExamples` such that the color of the widget for `backgroundColor` actually matches - Dropping support for MSVC14, new minimum compiler on Windows is MSVC15 (Visual Studio 2017) ### Changes in v2.4.0: - The `pathtracer` optionally allows for alpha blending even if the background is seen through refractive objects like glass, by enabling `backgroundRefraction` - OSPRay now requires minimum Open VKL v0.11.0 to bring the following improvements: - Improved rendering performance of VDB volumes - Added support for configurable iterator depth via the `maxIteratorDepth` parameters for unstructured and particle volumes, improved performance - Added support for filter modes for structured volumes (regular and spherical) - Expose parameter `horizonExtension` of Sun-sky light, which extends the sky dome by stretching the horizon over the lower hemisphere - Optimize handling of geometry lights by the `pathtracer` - The optional `denoiser` image operation now respects frame cancellation, requiring Intel® Open Image Denoise with minimum version 1.2.3 - Fixed normals of (transformed) isosurfaces - Robust calculation of normals of `boxes` geometry - Clipping geometry is now working correctly with `map_maxDepth` renderer parameter - Using materials in a renderer with a mismatched `renderer_type` no longer causes crashes while rendering - Significant improvements have been made to loading performance in the MPI Offload device. Applications which make large numbers of API calls or create many smaller geometries or volumes should see substantial load time improvements. - MPI module compacts strided data arrays on the app rank before sending ### Changes in v2.3.0: - Re-add SciVis renderer features (the previous version is still available as `ao` renderer) - Lights are regarded, and thus the OBJ material terms `ks` and `ns` have effect again - Hard shadows are enabled via the `shadows` parameter - The control of ambient occlusion changed: - The `aoIntensity` parameter is replaced by the combined intensity of ambient lights in the `World` - The effect range is controlled via `aoDistance` - Added support for data arrays with a stride between voxels in volumes - Application thread waiting for finished image via `ospWait` participates in rendering, increasing CPU utilization; via rkcommon v1.5.0 - Added `ospray_cpp` compatibility headers for C++ wrappers to understand rkcommon and glm short vector types - For rkcommon, include `ospray/ospray_cpp/ext/rkcommon.h` - For glm, include `ospray/ospray_cpp/ext/glm.h` - Note in debug builds some compilers will not optimize out type trait definitions. This will require users to manually instantiate the glm definitions in one translation unit within the application using `#define OSPRAY_GLM_DEFINITIONS` before including `ext/glm.h`: see `ospTutorialGLM` as an example - Changed parameters to `volume` texture: it now directly accepts the `volume` and the `transferFunction` - Fixed many memory leaks - Handle `NaN` during volume sampling, which led to bounding boxes being visible for some volumes and settings - Depth is now "accumulated" as well, using the minimum - Fix shading for multiple modes of the `debug` renderer - New minimum ISPC version is 1.14.1 ### Changes in v2.2.0: - Support for texture transformation in SciVis OBJ material - Add transformations for volume textures; volume texture lookups are now with local object coordinates (not world coordinates anymore) - Changed behavior: if solely a texture is given, then the default value of the corresponding parameter is *not* multiplied - Support for better antialiasing using a set of different pixel filters (e.g, box, Gaussian, ...). The size of the pixel filter is defined by the used filter type. Previously OSPRay implicitly used a box filter with a size of 1, for better results the default filter is now `OSP_PIXELFILTER_GAUSS` - Support stereo3d mode for panoramic camera - Add new camera `stereoMode` `OSP_STEREO_TOP_BOTTOM` (with left eye at top half of the image) - Added support for random light sampling to the `pathtracer`, the number of sampled light sources per path vertex is defined by the `lightSamples` parameter - Support ring light by extending spot with `innerRadius` - Fixed nonphysical behavior of the `spot` and `sphere` light sources - for area lights (when `radius > 0`) surfaces close to the light will be darker - the `spot` now has an angular falloff, such that a disk light is a proper lambertian area light, which leads to darker regions perpendicular to its direction (thus barely visible with a typically small `openingAngle`) - Support for Open VKL v0.10.0 and its new sampler object API, thus this is now the required minimum version - Added support for particle and VDB volumes - Move from `ospcommon` to `rkcommon` v1.4.2 - New minimum ISPC version is 1.10.0 - Status and error callbacks now support a user pointer - Enabled C++ wrappers (`ospray_cpp`) to work with non-rkcommon math types - Note that while the C API remains the same, the C++ wrappers will require some application updates to account for these changes - MPI module improved parallelism of framebuffer compression & decompression when collecting the final framebuffer to the head rank. This provides a substantial performance improvement when using just a few ranks or large framebuffers (both in pixel count or channel count). - The MPI module will now default to setting thread affinity off, if no option is selected. This improves thread usage and core assignment of threads in most cases, where no specific options are provided to the MPI runtime. - Fix bug where `ospGetCurrentDevice` would crash if used before `ospInit` - Allow `NULL` handles to be passed to `ospDeviceRetain` and `ospDeviceRelease` - ISPC generated headers containing the exported functions for OSPRay's ISPC types and functions are now distributed with the SDK - Add CarPaint `flakeColor` parameter, defaults to current Aluminium - Fixed Debug build (which were producing different images) - The path tracer now also regards the renderer materialist when creating geometry lights - Fix bug where OSPObject handles where not translated to worker-local pointers when committing an OSPData in the MPIOffloadDevice. - MPI module: Fix handling of `OSP_STRING` parameters ### Changes in v2.1.1: - CarPaint material obeys `coat` weight parameter - Correct depth buffer values with SciVis renderer - Adaptions to Embree v3.10.0 - The Linux binary release finds `ospcommon` again ### Changes in v2.1.0: - New clipping geometries feature that allows clipping any scene (geometry and volumes); all OSPRay geometry types can by used as clipping geometry - Inverted clipping is supported via new `invertNormals` parameter of `GeometricModel` - Currently there is a fixed upper limit (64) of how many clipping geometries can be nested - When clipping with curves geometry (any basis except linear) some rendering artifacts may appear - New plane geometry defined via plane equation and optional bounding box - Sun-sky light based on physical model of HoÅ¡ek-Wilkie - Support for photometric lights (e.g., IES or EULUMDAT) - Add new `ospGetTaskDuration` API call to query execution time of asynchronous tasks - Support for 16bit (unsigned short) textures - Add static `cpp::Device::current` method as a C++ wrapper equivalent to `ospGetCurrentDevice` - Generalized `cpp::Device` parameter setting to match other handle types - Passing `NULL` to `ospRelease` is not reported as error anymore - Fix computation of strides for `OSPData` - Fix transparency in `scivis` renderer - Add missing C++ wrapper for `ospGetVariance` - Proper demonstration of `ospGetVariance` in `ospTutorialAsync` - Fix handling of `--osp:device-params` to process and set all passed arguments first before committing the device, to ensure it is committed in a valid state - Object factory functions are now registered during module initialization via the appropriate `registerType` function - MPI module: Use flush bcasts to allow us to use non-owning views for data transfer. Note that shared `ospData` with strides is currently transmitted as whole - Fix issue with OSPRay ignoring tasking system thread count settings - Fix issue where OSPRay always loaded the ISPC module, even if not required - Fixes for MPI module - Fix member variable type for bcast - Fix incorrect data size computation in `offload` device - Fix large data chunking support for MPI Bcast - OSPRay now requires minimum Open VKL v0.9.0 ### Changes in v2.0.1: - Fix bug where Embree user-defined geometries were not indexed correctly in the scene, which now requires Embree v3.8.0+ - Fix crash when the path tracer encounters geometric models that do not have a material - Fix crash when some path tracer materials generated `NULL` bsdfs - Fix bug where `ospGetBounds` returned incorrect values - Fix missing symbol in denoiser module - Fix missing symbol exports on Windows for all OSPRay built modules - Add the option to specify a single color for geometric models - The `scivis` renderer now respects the opacity component of `color` on geometric models - Fix various inconsistent handling of framebuffer alpha between renderers - `ospGetCurrentDevice` now increments the ref count of the returned `OSPDevice` handle, so applications will need to release the handle when finished by using `ospDeviceRelease` accordingly - Added denoiser to `ospExamples` app - Added `module_mpi` to superbuild (disabled by default) - The superbuild now will emit a CMake error when using any 32-bit CMake generator, as 32-bit builds are not supported ### Changes in v2.0.0: - New major revision of OSPRay brings API breaking improvements over v1.x. See [doc/ospray2_porting_guide.md] for a deeper description of migrating from v1.x to v2.0 and the latest [API documentation](README.md#ospray-api) - `ospRenderFrame` now takes all participating objects as function parameters instead of setting some as renderer params - `ospRenderFrame` is now asynchronous, where the task is managed through a returned `OSPFuture` handle - The hierarchy of objects in a scene are now more granular to aid in scene construction flexibility and reduce potential object duplication - Type-specific parameter setting functions have been consolidated into a single `ospSetParam` API call - C++ wrappers found in `ospray_cpp.h` now automatically track handle lifetimes, therefore applications using them do not need to use `ospRelease` (or the new `ospRetain`) with them: see usage example in `apps/tutorials/ospTutorial.cpp` - Unused parameters are reported as status messages when `logLevel` is at least `warning` (most easily set by enabling OSPRay debug on initialization) - New utility library which adds functions to help with new API migration and reduction of boilerplate code - Use `ospray_util.h` to access these additional functions - All utility functions are implemented in terms of the core API found in `ospray.h`, therefore they are compatible with any device backend - Introduction of new Intel® Open Volume Kernel Library (Open VKL) for greatly enhanced volume sampling and rendering features and performance - Added direct support for Intel® Open Image Denoise as an optional module, which adds a `denoiser` type to `ospNewImageOperation` - OSPRay now requires minimum Embree v3.7.0 - New CMake superbuild available to build both OSPRay's dependencies and OSPRay itself - Found in `scripts/superbuild` - See documentation for more details and example usage - The `ospcommon` library now lives as a stand alone repository and is required to build OSPRay - The MPI module is now a separate repository, which also contains all MPI distributed rendering documentation - Log levels are now controlled with enums and named strings (where applicable) - A new flag was also introduced which turns all `OSP_LOG_WARNING` messages into errors, which are submitted to the error callback instead of the message callback - Any unused parameters an object ignores now emit a warning message - New support for volumes in the `pathtracer` - Several parameters are available for performance/quality trade-offs for both photorealistic and scientific visualization use cases - Simplification of the SciVis renderer - Fixed AO lighting and simple ray marched volume rendering for ease of use and performance - Overlapping volumes are now supported in both the `pathtracer` and `scivis` renderers - New API call for querying the bounds of objects (`OSPWorld`, `OSPInstance`, and `OSPGroup`) - Lights now exist as a parameter to the world instead of the renderer - Removal of `slices` geometry. Instead, any geometry with volume texture can be used for slicing - Introduction of new `boxes` geometry type - Expansion of information returned by `ospPick` - Addition of API to query version information at runtime - Curves now supports both, per vertex varying radii as in `vec4f[] vertex.position_radius` and constant radius for the geometry with `float radius`. It uses `OSP_ROUND` type and `OSP_LINEAR` basis by default to create the connected segments of constant radius. For per vertex varying radii curves it uses Embree curves. - Add new Embree curve type `OSP_CATMULL_ROM` for curves - Minimum required Embree version is now 3.7.0 - Removal of `cylinders` and `streamlines` geometry, use `curves` instead - Triangle mesh and Quad mesh are superseded by the `mesh` geometry - Applications need to use the various error reporting methods to check whether the creation (via `ospNew...`) of objects failed; a returned `NULL` is not a special handle anymore to signify an error - Changed module init methods to facilitate version checking: `extern "C" OSPError ospray_module_init_(int16_t versionMajor, int16_t versionMinor, int16_t versionPatch)` - The `map_backplate` texture is supported in all renderers and does not hide lights in infinity (like the HDRI light) anymore; explicitly make lights in`visible` if this is needed - Changed the computation of variance for adaptive accumulation to be independent of `TILE_SIZE`, thus `varianceThreshold` needs to be adapted if using a different `TILE_SIZE` than default 64 - `OSPGeometricModel` now has the option to index a renderer-global material list that lives on the renderer, allowing scenes to avoid renderer-specific materials - Object type names and parameters all now follow the camel-case convention - New `ospExamples` app which consolidates previous interactive apps into one - New `ospBenchmark` app which implements a runnable benchmark suite - Known issues: - ISPC v1.11.0 and Embree v3.6.0 are both incompatible with OSPRay and should be avoided (OSPRay should catch this during CMake configure) - MPI module - The MPI module is now provided separately from the main OSPRay repository - Users can now extend OSPRay with custom distributed renderers and compositing operations, by extending `ospray::mpi::DistributedRenderer` and the `ospray::mpi::TileOperation`, respectively. See the `ospray::mpi::DistributedRaycastRenderer` for an example to start from. - The MPI Offload device can now communicate over sockets, allowing for remote rendering on clusters in the listen/connect mode - Data and commands are now sent asynchronously to the MPI workers in the Offload device, overlapping better with application work. The number of data copies performed has also been significantly reduced, and should improve load times - The MPI Distributed device will now infer the rank's local data bounds based on the volumes and geometry specified if no bounding boxes are specified - When specifying custom bounds on each rank IDs are no longer required, and ranks sharing data will be determined by finding any specifying the same bounding boxes. This will also be done if no bounds are specified, allowing automatic image and hybrid parallel rendering. - The MPI Distributed device can now be used for image-parallel rendering (e.g., same as offload), where now each application can load data in parallel. See the `ospMPIDistributedTutorialReplicatedData` for an example. ### Changes in v1.8.5: - Fix float precision cornercase (`NaN`s) in sphere light sampling - Fix CMake bug that assumed `.git` was a directory, which is not true when using OSPRay as a git submodule - Fix CMake warning - Fix `DLL_EXPORT` issue with `ospray_testing` helper library on Windows ### Changes in v1.8.4: - Add location of `libospray` to paths searched to find modules ### Changes in v1.8.3: - Fix bug where parameters set by `ospSet1b()` were being ignored - Fix bug in box intersection tests possibly creating `NaN`s - Fix issue with client applications calling `find_package(ospray)` more than once - Fix bug in cylinder intersection when ray and cylinder are perpendicular - Fix rare crash in path tracer / MultiBSDF ### Changes in v1.8.2: - CMake bug fix where external users of OSPRay needed CMake newer than version 3.1 - Fix incorrect propagation of tasking system flags from an OSPRay install - Fix inconsistency between supported environment variables and command line parameters passed to `ospInit()` - Missing variables were `OSPRAY_LOAD_MODULES` and `OSPRAY_DEFAULT_DEVICE` ### Changes in v1.8.1: - CMake bug fix to remove full paths to dependencies in packages ### Changes in v1.8.0: - This will be the last minor revision of OSPRay. Future development effort in the `devel` branch will be dedicated to v2.0 API changes and may break existing v1.x applications. - This will also be the last version of OSPRay to include `ospray_sg` and the Example Viewer. Users which depend on these should instead use the separate OSPRay Studio project, where `ospray_sg` will be migrated. - We will continue to support patch releases of v1.8.x in case of any reported bugs - Refactored CMake to use newer CMake concepts - All targets are now exported in OSPRay installs and can be consumed by client projects with associated includes, libraries, and definitions - OSPRay now requires CMake v3.1 to build - See documentation for more details - Added new minimal tutorial apps to replace the more complex Example Viewer - Added new "`subdivision`" geometry type to support subdivision surfaces - Added support for texture formats `L8`, `LA8` (gamma-encoded luminance), and `RA8` (linear two component). Note that the enum `OSP_TEXTURE_FORMAT_INVALID` changed its value, thus recompilation may be necessary. - Automatic epsilon handling, which removes the "`epsilon`" parameter on all renderers - Normals in framebuffer channel `OSP_FB_NORMAL` are now in world-space - Added support for Intel® Open Image Denoise to the Example Viewer - This same integration will soon be ported to OSPRay Studio - Fixed artifacts for scaled instances of spheres, cylinders and streamlines - Improvements to precision of intersections with cylinders and streamlines - Fixed Quadlight: the emitting side is now indeed in direction `edge1`×`edge2` ### Changes in v1.7.3: - Make sure a "`default`" device can always be created - Fixed `ospNewTexture2D` (completely implementing old behavior) - Cleanup any shared object handles from the OS created from `ospLoadModule()` ### Changes in v1.7.2: - Fixed issue in `mpi_offload` device where `ospRelease` would sometimes not correctly free objects - Fixed issue in `ospray_sg` where structured volumes would not properly release the underlying OSPRay object handles ### Changes in v1.7.1: - Fixed issue where the `Principled` material would sometimes show up incorrectly as black - Fixed issue where some headers were missing from install packages ### Changes in v1.7.0: - Generalized texture interface to support more than classic 2D image textures, thus `OSPTexture2D` and `ospNewTexture2D` are now deprecated, use the new API call `ospNewTexture("texture2d")` instead - Added new `volume` texture type to visualize volume data on arbitrary geometry placed inside the volume - Added new framebuffer channels `OSP_FB_NORMAL` and `OSP_FB_ALBEDO` - Applications can get information about the progress of rendering the current frame, and optionally cancel it, by registering a callback function via `ospSetProgressFunc()` - Lights are not tied to the renderer type, so a new function `ospNewLight3()` was introduced to implement this. Please convert all uses of `ospNewLight()` and/or `ospNewLight2()` to `ospNewLight3()` - Added sheenTint parameter to Principled material - Added baseNormal parameter to Principled material - Added low-discrepancy sampling to path tracer - The `spp` parameter on the renderer no longer supports values less than 1, instead applications should render to a separate, lower resolution framebuffer during interaction to achieve the same behavior ### Changes in v1.6.1: - Many bug fixes - Quad mesh interpolation and sampling - Normal mapping in path tracer materials - Memory corruption with partly emitting mesh lights - Logic for setting thread affinity ### Changes in v1.6.0: - Updated ispc device to use Embree3 (minimum required Embree version is 3.1) - Added new `ospShutdown()` API function to aid in correctness and determinism of OSPRay API cleanup - Added "`Principled`" and "`CarPaint"` materials to the path tracer - Improved flexibility of the tone mapper - Improvements to unstructured volume - Support for wedges (in addition to tets and hexes) - Support for implicit isosurface geometry - Support for cell-centered data (as an alternative to per-vertex data) - Added an option to precompute normals, providing a memory/performance trade-off for applications - Implemented "`quads`" geometry type to handle quads directly - Implemented the ability to set "void" cell values in all volume types: when `NaN` is present as a volume's cell value the volume sample will be ignored by the SciVis renderer - Fixed support for color strides which were not multiples of `sizeof(float)` - Added support for RGBA8 color format to spheres, which can be set by specifying the "`color_format`" parameter as `OSP_UCHAR4`, or passing the "`color`" array through an `OSPData` of type `OSP_UCHAR4`. - Added ability to configure Embree scene flags via `OSPModel` parameters - `ospFreeFrameBuffer()` has been deprecated in favor of using `ospRelease()` to free framebuffer handles - Fixed memory leak caused by incorrect parameter reference counts in ispc device - Fixed occasional crashes in the `mpi_offload` device on shutdown - Various improvements to sample apps and `ospray_sg` - Added new `generator` nodes, allowing the ability to inject programmatically generated scene data (only C++ for now) - Bug fixes and improvements to enhance stability and usability ### Changes in v1.5.0: - Unstructured tetrahedral volume now generalized to also support hexahedral data, now called `unstructured_volume` - New function for creating materials (`ospNewMaterial2()`) which takes the renderer type string, not a renderer instance (the old version is now deprecated) - New `tonemapper` PixelOp for tone mapping final frames - Streamlines now support per-vertex radii and smooth interpolation - `ospray_sg` headers are now installed alongside the SDK - Core OSPRay ispc device now implemented as a module - Devices which implement the public API are no longer required to link the dependencies to core OSPRay (e.g., Embree v2.x) - By default, `ospInit()` will load the ispc module if a device was not created via `--osp:mpi` or `--osp:device:[name]` - MPI devices can now accept an existing world communicator instead of always creating their own - Added ability to control ISPC specific optimization flags via CMake options.

Applications need to recompile, because `OSPDataType` has been re-enumerated - Removed SciVis renderer parameter `aoWeight`, the intensity (and now color as well) of AO is controlled via "`ambient`" lights. If `aoSamples` is zero (the default) then ambient lights cause ambient illumination (without occlusion) - New SciVis renderer parameter `aoTransparencyEnabled`, controlling whether object transparency is respected when computing ambient occlusion (disabled by default, as it is considerable slower) - Implement normal mapping for SciVis renderer - Support of emissive (and illuminating) geometries in the path tracer via new material "`Luminous`" - Lights can optionally made invisible by using the new parameter `isVisible` (only relevant for path tracer) -

RenderKit-ospray-85af292/README.md000066400000000000000000006724461464752671100165750ustar00rootroot00000000000000OSPRay ====== This is release v3.2.0 of Intel® OSPRay. For changes and new features see the [changelog](CHANGELOG.md). Visit http://www.ospray.org for more information. OSPRay Overview =============== Intel® OSPRay is an **o**pen source, **s**calable, and **p**ortable **ray** tracing engine for high-performance, high-fidelity visualization on Intel Architecture CPUs, Intel Xe GPUs, and ARM64 CPUs. OSPRay is part of the [Intel Rendering Toolkit (Render Kit)](https://software.intel.com/en-us/rendering-framework) and is released under the permissive [Apache 2.0 license](http://www.apache.org/licenses/LICENSE-2.0). The purpose of OSPRay is to provide an open, powerful, and easy-to-use rendering library that allows one to easily build applications that use ray tracing based rendering for interactive applications (including both surface- and volume-based visualizations). OSPRay runs on anything from laptops, to workstations, to compute nodes in HPC systems. OSPRay internally builds on top of Intel [Embree](https://www.embree.org/), Intel [Open VKL](https://www.openvkl.org/), and Intel [Open Image Denoise](https://openimagedenoise.github.io/). The CPU implementation is based on Intel [ISPC (Implicit SPMD Program Compiler)](https://ispc.github.io/) and fully exploits modern instruction sets like Intel SSE4, AVX, AVX2, AVX-512 and NEON to achieve high rendering performance. Hence, a CPU with support for at least SSE4.1 is required to run OSPRay on x86_64 architectures, or a CPU with support for NEON is required to run OSPRay on ARM64 architectures. OSPRay’s GPU implementation (beta status) is based on the [SYCL](https://www.khronos.org/sycl/) cross-platform programming language implemented by [Intel oneAPI Data Parallel C++ (DPC++)](https://www.intel.com/content/www/us/en/developer/tools/oneapi/data-parallel-c-plus-plus.html) and currently supports Intel Arcâ„¢ GPUs on Linux and Windows, and Intel Data Center GPU Flex and Max Series on Linux, exploiting ray tracing hardware support. OSPRay Support and Contact -------------------------- OSPRay is under active development, and though we do our best to guarantee stable release versions a certain number of bugs, as-yet-missing features, inconsistencies, or any other issues are still possible. For any such requests or findings please use [OSPRay’s GitHub Issue Tracker](https://github.com/ospray/OSPRay/issues) (or, if you should happen to have a fix for it, you can also send us a pull request). To receive release announcements simply [“Watch†the OSPRay repository](https://github.com/ospray/OSPRay) on GitHub. Building and Finding OSPRay =========================== The latest OSPRay sources are always available at the [OSPRay GitHub repository](http://github.com/ospray/ospray). The default `master` branch should always point to the latest bugfix release. Prerequisites ------------- OSPRay currently supports Linux, Mac OS X, and Windows. In addition, before you can build OSPRay you need the following prerequisites: - You can clone the latest OSPRay sources via: ``` sh git clone https://github.com/ospray/ospray.git ``` - To build OSPRay you need [CMake](http://www.cmake.org), any form of C++11 compiler (we recommend using GCC, but also support Clang, MSVC, and [Intel® C++ Compiler (icc)](https://software.intel.com/en-us/c-compilers)), and standard Linux development tools. - Additionally you require a copy of the [Intel® Implicit SPMD Program Compiler (ISPC)](http://ispc.github.io), version 1.23.0 or later. Please obtain a release of ISPC from the [ISPC downloads page](https://ispc.github.io/downloads.html). If ISPC is not found by CMake its location can be hinted with the variable `ISPC_EXECUTABLE`. - OSPRay builds on top of the [Intel Rendering Toolkit (Render Kit) common library (rkcommon)](https://www.github.com/ospray/rkcommon). The library provides abstractions for tasking, aligned memory allocation, vector math types, among others. For users who also need to build rkcommon, we recommend the default the Intel [Threading Building Blocks (TBB)](https://www.threadingbuildingblocks.org/) as tasking system for performance and flexibility reasons. TBB must be built from source when targeting ARM CPUs, or can be built from source as part of the [superbuild](#cmake-superbuild). Alternatively you can set CMake variable `RKCOMMON_TASKING_SYSTEM` to `OpenMP` or `Internal`. - OSPRay also heavily uses Intel [Embree](https://www.embree.org/), installing version 4.3.3 or newer is required. If Embree is not found by CMake its location can be hinted with the variable `embree_DIR`. - OSPRay supports volume rendering (enabled by default via `OSPRAY_ENABLE_VOLUMES`), which heavily uses Intel [Open VKL](https://www.openvkl.org/), version 2.0.1 or newer is required. If Open VKL is not found by CMake its location can be hinted with the variable `openvkl_DIR`, or disable `OSPRAY_ENABLE_VOLUMES`. - OSPRay also provides an optional module implementing the `denoiser` image operation, which is enabled by `OSPRAY_MODULE_DENOISER`. This module requires Intel [Open Image Denoise](https://openimagedenoise.github.io/) in version 2.3.0 or newer. You may need to hint the location of the library with the CMake variable `OpenImageDenoise_DIR`. - For the optional MPI modules (enabled by `OSPRAY_MODULE_MPI`), which provide the `mpiOffload` and `mpiDistributed` devices, you need an MPI library and [Google Snappy](https://github.com/google/snappy). - The optional example application, the test suit and benchmarks need some version of OpenGL and GLFW as well as [GoogleTest](https://github.com/google/googletest) and [Google Benchmark](https://github.com/google/benchmark/) Depending on your Linux distribution you can install these dependencies using `yum` or `apt-get`. Some of these packages might already be installed or might have slightly different names. Type the following to install the dependencies using `yum`: ``` sh sudo yum install cmake.x86_64 sudo yum install tbb.x86_64 tbb-devel.x86_64 ``` Type the following to install the dependencies using `apt-get`: ``` sh sudo apt-get install cmake-curses-gui sudo apt-get install libtbb-dev ``` Under Mac OS X these dependencies can be installed using [MacPorts](http://www.macports.org/): ``` sh sudo port install cmake tbb ``` Under Windows please directly use the appropriate installers for [CMake](https://cmake.org/download/), [TBB](https://github.com/oneapi-src/oneTBB/releases), [ISPC](https://ispc.github.io/downloads.html) (for your Visual Studio version) and [Embree](https://github.com/embree/embree/releases/). ### Additional Prerequisites for GPU Build To build OSPRay’s GPU module you need - a SYCL compiler, either the open source [oneAPI DPC++ Compiler 2023-10-26](https://github.com/intel/llvm/releases/tag/nightly-2023-10-26) or the latest [Intel oneAPI DPC++/C++ Compiler](https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html#dpcpp-cpp) - a recent [CMake](http://www.cmake.org), version 3.25.3 or higher CMake Superbuild ---------------- For convenience, OSPRay provides a CMake Superbuild script which will pull down OSPRay’s dependencies and build OSPRay itself. By default, the result is an install directory, with each dependency in its own directory. Run with: ``` sh mkdir build cd build cmake [/scripts/superbuild] cmake --build . ``` On Windows make sure to select a 64 bit generator, e.g. ``` sh cmake -G "Visual Studio 17 2022" [/scripts/superbuild] ``` The resulting `install` directory (or the one set with `CMAKE_INSTALL_PREFIX`) will have everything in it, with one subdirectory per dependency. CMake options to note (all have sensible defaults): CMAKE_INSTALL_PREFIX will be the root directory where everything gets installed. BUILD_JOBS sets the number given to `make -j` for parallel builds. INSTALL_IN_SEPARATE_DIRECTORIES toggles installation of all libraries in separate or the same directory. BUILD_OPENVKL whether to enable volume rendering via Open VKL BUILD_EMBREE_FROM_SOURCE set to OFF will download a pre-built version of Embree. BUILD_OIDN_FROM_SOURCE set to OFF will download a pre-built version of Open Image Denoise. OIDN_VERSION determines which version of Open Image Denoise to pull down. BUILD_OSPRAY_MODULE_MPI set to ON to build OSPRay’s MPI module for data-replicated and distributed parallel rendering on multiple nodes. BUILD_GPU_SUPPORT enables beta GPU support, fetching the SYCL variants of the dependencies and builds `OSPRAY_MODULE_GPU` BUILD_TBB_FROM_SOURCE set to ON to build TBB from source (required for ARM support). The default setting is OFF. For the full set of options, run: ``` sh ccmake [/scripts/superbuild] ``` or ``` sh cmake-gui [/scripts/superbuild] ``` ### Cross-Compilation with the Superbuild The superbuild can be passed a [CMake Toolchain file](https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html) to configure for cross-compilation. This is done by passing the toolchain file when running cmake. When cross compiling it is also likely that you’ll want to build TBB and Embree from source to ensure they’re built for the correct target, rather than the target the Github binaries are built for. It may also be necessary to disable specific ISAs for the target by passing `BUILD_ISA_=OFF` as well. ``` sh mkdir build cd build cmake --toolchain [toolchain_file.cmake] [path/to/this/directory] -DBUILD_TBB_FROM_SOURCE=ON \ -DBUILD_EMBREE_FROM_SOURCE=ON \ ``` While OSPRay supports ARM natively, it may be desirable to cross-compile it for `x86_64` to run in Rosetta depending on the application integrating OSPRay. This can be done using the toolchain file `toolchains/macos-rosetta.cmake`, and by disabling all non-SSE ISAs when building. This can also be done by launching an `x86_64` bash shell and then compiling as usual in this environment, which will cause the compilation chain to target `x86_64`. The `BUILD_ISA_=OFF` flags should be passed to disable all ISAs besides SSE4 for Rosetta: ``` sh arch -x86_64 bash mkdir build cd build cmake [path/to/this/directory] -DBUILD_TBB_FROM_SOURCE=ON \ -DBUILD_EMBREE_FROM_SOURCE=ON \ -DBUILD_ISA_AVX=OFF \ -DBUILD_ISA_AVX2=OFF \ -DBUILD_ISA_AVX512=OFF \ ``` Standard CMake Build -------------------- ### Compiling OSPRay on Linux and Mac OS X Assuming the above requisites are all fulfilled, building OSPRay through CMake is easy: - Create a build directory, and go into it ``` sh mkdir ospray/build cd ospray/build ``` (We do recommend having separate build directories for different configurations such as release, debug, etc.). - The compiler CMake will use will default to whatever the `CC` and `CXX` environment variables point to. Should you want to specify a different compiler, run cmake manually while specifying the desired compiler. The default compiler on most linux machines is `gcc`, but it can be pointed to `clang` instead by executing the following: ``` sh cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang .. ``` CMake will now use Clang instead of GCC. If you are OK with using the default compiler on your system, then simply skip this step. Note that the compiler variables cannot be changed after the first `cmake` or `ccmake` run. - Open the CMake configuration dialog ``` sh ccmake .. ``` - Make sure to properly set build mode and enable the components you need, etc.; then type ’c’onfigure and ’g’enerate. When back on the command prompt, build it using ``` sh make ``` - You should now have `libospray.[so,dylib]` as well as a set of [example applications](#tutorials). ### Compiling OSPRay on Windows On Windows using the CMake GUI (`cmake-gui.exe`) is the most convenient way to configure OSPRay and to create the Visual Studio solution files: - Browse to the OSPRay sources and specify a build directory (if it does not exist yet CMake will create it). - Click “Configure†and select as generator the Visual Studio version you have; OSPRay needs “Visual Studio 15 2017 Win64†or newer, 32 bit builds are not supported, e.g., “Visual Studio 17 2022â€. - If the configuration fails because some dependencies could not be found then follow the instructions given in the error message, e.g., set the variable `embree_DIR` to the folder where Embree was installed and `openvkl_DIR` to where Open VKL was installed. - Optionally change the default build options, and then click “Generate†to create the solution and project files in the build directory. - Open the generated `OSPRay.sln` in Visual Studio, select the build configuration and compile the project. Alternatively, OSPRay can also be built without any GUI, entirely on the console. In the Visual Studio command prompt type: ``` sh cd path\to\ospray mkdir build cd build cmake -G "Visual Studio 17 2022" [-D VARIABLE=value] .. cmake --build . --config Release ``` Use `-D` to set variables for CMake, e.g., the path to Embree with “`-D embree_DIR=\path\to\embree`â€. You can also build only some projects with the `--target` switch. Additional parameters after “`--`†will be passed to `msbuild`. For example, to build in parallel only the OSPRay library without the example applications use ``` sh cmake --build . --config Release --target ospray -- /m ``` Finding an OSPRay Install with CMake ------------------------------------ Client applications using OSPRay can find it with CMake’s `find_package()` command. For example, ``` sh find_package(ospray 3.0.0 REQUIRED) ``` finds OSPRay via OSPRay’s configuration file `osprayConfig.cmake`[^1]. Once found, the following is all that is required to use OSPRay: ``` sh target_link_libraries(${client_target} ospray::ospray) ``` This will automatically propagate all required include paths, linked libraries, and compiler definitions to the client CMake target (either an executable or library). Advanced users may want to link to additional targets which are exported in OSPRay’s CMake config, which includes all installed modules. All targets built with OSPRay are exported in the `ospray::` namespace, therefore all targets locally used in the OSPRay source tree can be accessed from an install. For example, `ospray_module_cpu` can be consumed directly via the `ospray::ospray_module_cpu` target. All targets have their libraries, includes, and definitions attached to them for public consumption (please [report bugs](#ospray-support-and-contact) if this is broken!). Documentation ============= The following [API documentation](https://www.ospray.org/OSPRay_readme.pdf "OSPRay Documentation") of OSPRay can also be found as a [pdf document](https://www.ospray.org/OSPRay_readme.pdf "OSPRay Documentation"). For a deeper explanation of the concepts, design, features and performance of OSPRay also have a look at the IEEE Vis 2016 paper “[OSPRay – A CPU Ray Tracing Framework for Scientific Visualization](https://www.ospray.org/talks/IEEEVis2016_OSPRay_paper.pdf)†(49MB, or get the [smaller version](https://www.ospray.org/talks/IEEEVis2016_OSPRay_paper_small.pdf) 1.8MB). The [slides of the talk](https://www.ospray.org/talks/IEEEVis2016_OSPRay_talk.pdf) (5.2MB) are also available. OSPRay API ========== To access the OSPRay API you first need to include the OSPRay header ``` cpp #include "ospray/ospray.h" ``` where the API is compatible with C99 and C++. Initialization and Shutdown --------------------------- To use the API, OSPRay must be initialized with a “deviceâ€. A device is the object which implements the API. Creating and initializing a device can be done in either of two ways: command line arguments using `ospInit` or manually instantiating a device and setting parameters on it. ### Command Line Arguments The first is to do so by giving OSPRay the command line from `main()` by calling ``` cpp OSPError ospInit(int *argc, const char **argv); ``` OSPRay parses (and removes) its known command line parameters from your application’s `main` function. For an example see the [tutorial](#osptutorial). For possible error codes see section [Error Handling and Status Messages](#error-handling-and-status-messages). It is important to note that the arguments passed to `ospInit` are processed in order they are listed. The following parameters (which are prefixed by convention with “`--osp:`â€) are understood: | Parameter | Description | |:--------------------------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `--osp:debug` | enables various extra checks and debug output, and disables multi-threading | | `--osp:num-threads=` | use `n` threads instead of per default using all detected hardware threads | | `--osp:log-level=` | set logging level; valid values (in order of severity) are `none`, `error`, `warning`, `info`, and `debug` | | `--osp:warn-as-error` | send `warning` and `error` messages through the error callback, otherwise send `warning` messages through the message callback; must have sufficient `logLevel` to enable warnings | | `--osp:verbose` | shortcut for `--osp:log-level=info` and enable debug output on `cout`, error output on `cerr` | | `--osp:vv` | shortcut for `--osp:log-level=debug` and enable debug output on `cout`, error output on `cerr` | | `--osp:load-modules=[,...]` | load one or more modules during initialization; equivalent to calling `ospLoadModule(name)` | | `--osp:log-output=` | convenience for setting where status messages go; valid values for `dst` are `cerr` and `cout` | | `--osp:error-output=` | convenience for setting where error messages go; valid values for `dst` are `cerr` and `cout` | | `--osp:device=` | use `name` as the type of device for OSPRay to create; e.g., `--osp:device=cpu` gives you the default `cpu` device; Note if the device to be used is defined in a module, remember to pass `--osp:load-modules=` first | | `--osp:set-affinity=` | if `1`, bind software threads to hardware threads; `0` disables binding; default is `0` | | `--osp:device-params=:[,...]` | set one or more other device parameters; equivalent to calling `ospDeviceSet*(param, value)` | Command line parameters accepted by OSPRay’s `ospInit`. ### Manual Device Instantiation The second method of initialization is to explicitly create the device and possibly set parameters. This method looks almost identical to how other [objects](#objects) are created and used by OSPRay (described in later sections). The first step is to create the device with ``` cpp OSPDevice ospNewDevice(const char *type); ``` where the `type` string maps to a specific device implementation. OSPRay always provides the “`cpu`†device, which maps to a fast, local CPU implementation. Other devices can also be added through additional modules, such as distributed MPI device implementations. See next Chapter for details. Once a device is created, you can call ``` cpp void ospDeviceSetParam(OSPObject, const char *id, OSPDataType type, const void *mem); ``` to set parameters on the device. The semantics of setting parameters is exactly the same as `ospSetParam`, which is documented below in the [parameters](#parameters) section. The following parameters can be set on all devices: | Type | Name | Description | |:-------|:------------------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | int | numThreads | number of threads which OSPRay should use | | bool | disableMipMapGeneration | disable the default generation of MIP maps for textures (e.g., to save the additional memory needed) | | uint | logLevel | logging level; valid values (in order of severity) are `OSP_LOG_NONE`, `OSP_LOG_ERROR`, `OSP_LOG_WARNING`, `OSP_LOG_INFO`, and `OSP_LOG_DEBUG` | | string | logOutput | convenience for setting where status messages go; valid values are `cerr` and `cout` | | string | errorOutput | convenience for setting where error messages go; valid values are `cerr` and `cout` | | bool | debug | set debug mode; equivalent to `logLevel=debug` and `numThreads=1` | | bool | warnAsError | send `warning` and `error` messages through the error callback, otherwise send `warning` messages through the message callback; must have sufficient `logLevel` to enable warnings | | bool | setAffinity | bind software threads to hardware threads if set to 1; 0 disables binding omitting the parameter will let OSPRay choose | Parameters shared by all devices. Once parameters are set on the created device, the device must be committed with ``` cpp void ospDeviceCommit(OSPDevice); ``` To use the newly committed device, you must call ``` cpp void ospSetCurrentDevice(OSPDevice); ``` This then sets the given device as the object which will respond to all other OSPRay API calls. Device handle lifetimes are managed with two calls, the first which increments the internal reference count to the given `OSPDevice` ``` cpp void ospDeviceRetain(OSPDevice) ``` and the second which decrements the reference count ``` cpp void ospDeviceRelease(OSPDevice) ``` Users can change parameters on the device after initialization (from either method above), by calling ``` cpp OSPDevice ospGetCurrentDevice(); ``` This function returns the handle to the device currently used to respond to OSPRay API calls, where users can set/change parameters and recommit the device. If changes are made to the device that is already set as the current device, it does not need to be set as current again. Note this API call will increment the ref count of the returned device handle, so applications must use `ospDeviceRelease` when finished using the handle to avoid leaking the underlying device object. If there is no current device set, this will return an invalid `NULL` handle. When a device is created, its reference count is initially `1`. When a device is set as the current device, it internally has its reference count incremented. Note that `ospDeviceRetain` and `ospDeviceRelease` should only be used with reference counts that the application tracks: removing reference held by the current set device should be handled by `ospShutdown`. Thus, `ospDeviceRelease` should only decrement the reference counts that come from `ospNewDevice`, `ospGetCurrentDevice`, and the number of explicit calls to `ospDeviceRetain`. OSPRay allows applications to query runtime properties of a device in order to do enhanced validation of what device was loaded at runtime. The following function can be used to get these device-specific properties (attributes about the device, not parameter values) ``` cpp int64_t ospDeviceGetProperty(OSPDevice, OSPDeviceProperty); ``` It returns an integer value of the queried property and the following properties can be provided as parameter: ``` cpp OSP_DEVICE_VERSION OSP_DEVICE_VERSION_MAJOR OSP_DEVICE_VERSION_MINOR OSP_DEVICE_VERSION_PATCH OSP_DEVICE_SO_VERSION ``` ### Environment Variables OSPRay’s generic device parameters can be overridden via environment variables for easy changes to OSPRay’s behavior without needing to change the application (variables are prefixed by convention with “`OSPRAY_`â€): | Variable | Description | |:---------------------|:-----------------------------------------------------------------------------------------------------------| | OSPRAY_NUM_THREADS | equivalent to `--osp:num-threads` | | OSPRAY_LOG_LEVEL | equivalent to `--osp:log-level` | | OSPRAY_LOG_OUTPUT | equivalent to `--osp:log-output` | | OSPRAY_ERROR_OUTPUT | equivalent to `--osp:error-output` | | OSPRAY_DEBUG | equivalent to `--osp:debug` | | OSPRAY_WARN_AS_ERROR | equivalent to `--osp:warn-as-error` | | OSPRAY_SET_AFFINITY | equivalent to `--osp:set-affinity` | | OSPRAY_LOAD_MODULES | equivalent to `--osp:load-modules`, can be a comma separated list of modules which will be loaded in order | | OSPRAY_DEVICE | equivalent to `--osp:device:` | Environment variables interpreted by OSPRay. Note that these environment variables take precedence over values specified through `ospInit` or manually set device parameters. ### Error Handling and Status Messages The following errors are currently used by OSPRay: | Name | Description | |:----------------------|:-----------------------------------------------------------------------------| | OSP_NO_ERROR | no error occurred | | OSP_UNKNOWN_ERROR | an unknown error occurred | | OSP_INVALID_ARGUMENT | an invalid argument was specified | | OSP_INVALID_OPERATION | the operation is not allowed for the specified object | | OSP_OUT_OF_MEMORY | there is not enough memory to execute the command | | OSP_UNSUPPORTED_CPU | the CPU is not supported (minimum ISA is SSE4.1 on x86_64 and NEON on ARM64) | | OSP_VERSION_MISMATCH | a module could not be loaded due to mismatching version | Possible error codes, i.e., valid named constants of type `OSPError`. These error codes are either directly return by some API functions, or are recorded to be later queried by the application via ``` cpp OSPError ospDeviceGetLastErrorCode(OSPDevice); ``` A more descriptive error message can be queried by calling ``` cpp const char* ospDeviceGetLastErrorMsg(OSPDevice); ``` Alternatively, the application can also register a callback function of type ``` cpp typedef void (*OSPErrorCallback)(void *userData, OSPError, const char* errorDetails); ``` via ``` cpp void ospDeviceSetErrorCallback(OSPDevice, OSPErrorCallback, void *userData); ``` to get notified when errors occur. Applications may be interested in messages which OSPRay emits, whether for debugging or logging events. Applications can call ``` cpp void ospDeviceSetStatusCallback(OSPDevice, OSPStatusCallback, void *userData); ``` in order to register a callback function of type ``` cpp typedef void (*OSPStatusCallback)(void *userData, const char* messageText); ``` which OSPRay will use to emit status messages. By default, OSPRay uses a callback which does nothing, so any output desired by an application will require that a callback is provided. Note that callbacks for C++ `std::cout` and `std::cerr` can be alternatively set through `ospInit` or the `OSPRAY_LOG_OUTPUT` environment variable. Applications can clear either callback by passing `NULL` instead of an actual function pointer. ### Loading OSPRay Extensions at Runtime OSPRay’s functionality can be extended via plugins (which we call “modulesâ€), which are implemented in shared libraries. To load module `name` from `libospray_module_.so` (on Linux and Mac OS X) or `ospray_module_.dll` (on Windows) use ``` cpp OSPError ospLoadModule(const char *name); ``` Modules are searched in OS-dependent paths. `ospLoadModule` returns `OSP_NO_ERROR` if the plugin could be successfully loaded. ### Shutting Down OSPRay When the application is finished using OSPRay (typically on application exit), the OSPRay API should be finalized with ``` cpp void ospShutdown(); ``` This API call ensures that the current device is cleaned up appropriately. Due to static object allocation having non-deterministic ordering, it is recommended that applications call `ospShutdown` before the calling application process terminates. Objects ------- All entities of OSPRay (the [renderer](#renderers), [volumes](#volumes), [geometries](#geometries), [lights](#lights), [cameras](#cameras), …) are a logical specialization of `OSPObject` and share common mechanism to deal with parameters and lifetime. An important aspect of object parameters is that parameters do not get passed to objects immediately. Instead, parameters are not visible at all to objects until they get explicitly committed to a given object via a call to ``` cpp void ospCommit(OSPObject); ``` at which time all previously additions or changes to parameters are visible at the same time. If a user wants to change the state of an existing object (e.g., to change the origin of an already existing camera) it is perfectly valid to do so, as long as the changed parameters are recommitted. The commit semantic allow for batching up multiple small changes, and specifies exactly when changes to objects will occur. This can impact performance and consistency for devices crossing a PCI bus or across a network. Note that OSPRay uses reference counting to manage the lifetime of all objects, so one cannot explicitly “delete†any object. Instead, to indicate that the application does not need and does not access the given object anymore, call ``` cpp void ospRelease(OSPObject); ``` This decreases its reference count and if the count reaches `0` the object will automatically get deleted. Passing `NULL` is not an error. Note that every handle returned via the API needs to be released when the object is no longer needed, to avoid memory leaks. Sometimes applications may want to have more than one reference to an object, where it is desirable for the application to increment the reference count of an object. This is done with ``` cpp void ospRetain(OSPObject); ``` It is important to note that this is only necessary if the application wants to call `ospRelease` on an object more than once: objects which contain other objects as parameters internally increment/decrement ref counts and should not be explicitly done by the application. ### Parameters Parameters allow to configure the behavior of and to pass data to objects. However, objects do *not* have an explicit interface for reasons of high flexibility and a more stable compile-time API. Instead, parameters are passed separately to objects in an arbitrary order, and unknown parameters will simply be ignored (though a warning message will be posted). The following function allows adding various types of parameters with name `id` to a given object: ``` cpp void ospSetParam(OSPObject, const char *id, OSPDataType type, const void *mem); ``` The valid parameter names for all `OSPObject`s and what types are valid are discussed in future sections. Note that `mem` must always be a pointer *to* the object, otherwise accidental type casting can occur. This is especially true for pointer types (`OSP_VOID_PTR` and `OSPObject` handles), as they will implicitly cast to `void *`, but be incorrectly interpreted. To help with some of these issues, there also exist variants of `ospSetParam` for specific types, such as `ospSetInt` and `ospSetVec3f` in the OSPRay utility library (found in `ospray_util.h`). Note that half precision float parameters `OSP_HALF, OSP_VEC[234]H` are not supported. Users can also remove parameters that have been explicitly set from `ospSetParam`. Any parameters which have been removed will go back to their default value during the next commit unless a new parameter was set after the parameter was removed. To remove a parameter, use ``` cpp void ospRemoveParam(OSPObject, const char *id); ``` ### Data OSPRay consumes data arrays from the application using a specific object type, `OSPData`. There are several components to describing a data array: element type, 1/2/3 dimensional striding, and whether the array is shared with the application or copied into opaque, OSPRay-owned memory. Shared data arrays require that the application’s array memory outlives the lifetime of the created `OSPData`, as OSPRay is referring to application memory. Where this is not preferable, applications use opaque arrays to allow the `OSPData` to own the lifetime of the array memory. However, opaque arrays dictate the cost of copying data into it, which should be kept in mind. Thus, the most efficient way to specify a data array from the application is to created a shared data array, which is done with ``` cpp OSPData ospNewSharedData(const void *sharedData, OSPDataType, uint64_t numItems1, int64_t byteStride1 = 0, uint64_t numItems2 = 1, int64_t byteStride2 = 0, uint64_t numItems3 = 1, int64_t byteStride3 = 0, OSPDeleterCallback = NULL, void *userData = NULL); ``` The call returns an `OSPData` handle to the created array. The calling program guarantees that the `sharedData` pointer will remain valid for the duration that this data array is being used. The number of elements `numItems` must be positive (there cannot be an empty data object). The data is arranged in three dimensions, with specializations to two or one dimension (if some `numItems` are 1). The distance between consecutive elements (per dimension) is given in bytes with `byteStride` and can also be negative. If `byteStride` is zero it will be determined automatically (e.g., as `sizeof(type)`). Strides do not need to be ordered, i.e., `byteStride2` can be smaller than `byteStride1`, which is equivalent to a transpose. However, if the stride should be calculated, then an ordering in dimensions is assumed to disambiguate, i.e., `byteStride1 < byteStride2 < byteStride3`. An application can pass ownership of shared data to OSPRay (for example, when it temporarily created a modified version of its data only to make it compatible with OSPRay) by providing a deleter function that OSPRay will call whenever the time comes to deallocate the shared buffer. The deleter function has the following signature: ``` cpp typedef void (*OSPDeleterCallback)(const void *userData, const void *sharedData); ``` where `sharedData` will receive the address of the buffer and `userData` will receive whatever additional state the function needs to perform the deletion (both provided to `ospNewSharedData` when sharing the data with OSPRay). The enum type `OSPDataType` describes the different element types that can be represented in OSPRay; valid constants are listed in the table below. | Type / Name | Description | |:-----------------------------|:---------------------------------------------------------------------------------------------| | OSP_DEVICE | API device object reference | | OSP_DATA | data reference | | OSP_OBJECT | generic object reference | | OSP_CAMERA | camera object reference | | OSP_FRAMEBUFFER | framebuffer object reference | | OSP_FUTURE | future object reference | | OSP_LIGHT | light object reference | | OSP_MATERIAL | material object reference | | OSP_TEXTURE | texture object reference | | OSP_RENDERER | renderer object reference | | OSP_WORLD | world object reference | | OSP_GROUP | group object reference | | OSP_INSTANCE | instance object reference | | OSP_GEOMETRY | geometry object reference | | OSP_GEOMETRIC_MODEL | geometric model object reference | | OSP_VOLUME | volume object reference | | OSP_VOLUMETRIC_MODEL | volumetric model object reference | | OSP_TRANSFER_FUNCTION | transfer function object reference | | OSP_IMAGE_OPERATION | image operation object reference | | OSP_STRING | C-style zero-terminated character string | | OSP_BOOL | 8 bit boolean | | OSP_CHAR, OSP_VEC\[234\]C | 8 bit signed character scalar and \[234\]-element vector | | OSP_UCHAR, OSP_VEC\[234\]UC | 8 bit unsigned character scalar and \[234\]-element vector | | OSP_SHORT, OSP_VEC\[234\]S | 16 bit unsigned integer scalar and \[234\]-element vector | | OSP_USHORT, OSP_VEC\[234\]US | 16 bit unsigned integer scalar and \[234\]-element vector | | OSP_INT, OSP_VEC\[234\]I | 32 bit signed integer scalar and \[234\]-element vector | | OSP_UINT, OSP_VEC\[234\]UI | 32 bit unsigned integer scalar and \[234\]-element vector | | OSP_LONG, OSP_VEC\[234\]L | 64 bit signed integer scalar and \[234\]-element vector | | OSP_ULONG, OSP_VEC\[234\]UL | 64 bit unsigned integer scalar and \[234\]-element vector | | OSP_HALF, OSP_VEC\[234\]H | 16 bit half precision floating-point scalar and \[234\]-element vector (IEEE 754 `binary16`) | | OSP_FLOAT, OSP_VEC\[234\]F | 32 bit single precision floating-point scalar and \[234\]-element vector | | OSP_DOUBLE, OSP_VEC\[234\]D | 64 bit double precision floating-point scalar and \[234\]-element vector | | OSP_BOX\[1234\]I | 32 bit integer box (lower + upper bounds) | | OSP_BOX\[1234\]F | 32 bit single precision floating-point box (lower + upper bounds) | | OSP_LINEAR\[23\]F | 32 bit single precision floating-point linear transform (\[23\] vectors) | | OSP_AFFINE\[23\]F | 32 bit single precision floating-point affine transform (linear transform plus translation) | | OSP_QUATF | 32 bit single precision floating-point quaternion, in $(i, j, k, w)$ layout | | OSP_VOID_PTR | raw memory address (only found in module extensions) | Valid named constants for `OSPDataType`. If the elements of the array are handles to objects, then their reference counter is incremented. An opaque `OSPData` with memory allocated by OSPRay is created with ``` cpp OSPData ospNewData(OSPDataType, uint64_t numItems1, uint64_t numItems2 = 1, uint64_t numItems3 = 1); ``` To allow for (partial) copies or updates of data arrays use ``` cpp void ospCopyData(const OSPData source, OSPData destination, uint64_t destinationIndex1 = 0, uint64_t destinationIndex2 = 0, uint64_t destinationIndex3 = 0); ``` which will copy the whole[^2] content of the `source` array into `destination` at the given location `destinationIndex`. The `OSPDataType`s of the data objects must match. The region to be copied must be valid inside the destination, i.e., in all dimensions, `destinationIndex + sourceSize <= destinationSize`. The affected region `[destinationIndex, destinationIndex + sourceSize)` is marked as dirty, which may be used by OSPRay to only process or update that sub-region (e.g., updating an acceleration structure). If the destination array is shared with OSPData by the application (created with `ospNewSharedData`), then - the source array must be shared as well (thus `ospCopyData` cannot be used to read opaque data) - if source and destination memory overlaps (aliasing), then behavior is undefined - except if source and destination regions are identical (including matching strides), which can be used by application to mark that region as dirty (instead of the whole `OSPData`) To add a data array as parameter named `id` to another object call also use ``` cpp void ospSetObject(OSPObject, const char *id, OSPData); ``` Volumes ------- Volumes are volumetric data sets with discretely sampled values in 3D space, typically a 3D scalar field. To create a new volume object of given type `type` use ``` cpp OSPVolume ospNewVolume(const char *type); ``` Note that OSPRay’s implementation forwards `type` directly to Open VKL, allowing new Open VKL volume types to be usable within OSPRay without the need to change (or even recompile) OSPRay. ### Structured Regular Volume Structured volumes only need to store the values of the samples, because their addresses in memory can be easily computed from a 3D position. A common type of structured volumes are regular grids. Structured regular volumes are created by passing the type string “`structuredRegular`†to `ospNewVolume`. Structured volumes are represented through an `OSPData` 3D array `data` (which may or may not be shared with the application). The voxel data must be laid out in xyz-order[^3] and can be compact (best for performance) or can have a stride between voxels, specified through the `byteStride1` parameter when creating the `OSPData`. Only 1D strides are supported, additional strides between scanlines (2D, `byteStride2`) and slices (3D, `byteStride3`) are not. The parameters understood by structured volumes are summarized in the table below. | Type | Name | Default | Description | |:--------|:---------------|---------------------------:|:--------------------------------------------------------------------------------------------------------------------| | vec3f | gridOrigin | $(0, 0, 0)$ | origin of the grid in object-space | | vec3f | gridSpacing | $(1, 1, 1)$ | size of the grid cells in object-space | | OSPData | data | | the actual voxel 3D [data](#data) | | bool | cellCentered | false | whether the data is provided per cell (as opposed to per vertex) | | uint | filter | `OSP_VOLUME_FILTER_LINEAR` | filter used for reconstructing the field, also allowed is `OSP_VOLUME_FILTER_NEAREST` and `OSP_VOLUME_FILTER_CUBIC` | | uint | gradientFilter | same as `filter` | filter used during gradient computations | | float | background | `NaN` | value that is used when sampling an undefined region outside the volume domain | Configuration parameters for structured regular volumes. The size of the volume is inferred from the size of the 3D array `data`, as is the type of the voxel values (currently supported are: `OSP_UCHAR`, `OSP_SHORT`, `OSP_USHORT`, `OSP_HALF`, `OSP_FLOAT`, and `OSP_DOUBLE`). Data can be provided either per cell or per vertex (the default), selectable via the `cellCentered` parameter (which will also affect the computed bounding box). ### Structured Spherical Volume Structured spherical volumes are also supported, which are created by passing a type string of “`structuredSpherical`†to `ospNewVolume`. The grid dimensions and parameters are defined in terms of radial distance $r$, inclination angle $\theta$, and azimuthal angle $\phi$, conforming with the ISO convention for spherical coordinate systems. The coordinate system and parameters understood by structured spherical volumes are summarized below.
Coordinate system of structured spherical volumes.
| Type | Name | Default | Description | |:--------|:---------------|----------------------------:|:----------------------------------------------------------------------------------------------------------------| | vec3f | gridOrigin | $(0, 0, 0)$ | origin of the grid in units of $(r, \theta, \phi)$; angles in degrees | | vec3f | gridSpacing | $(1, 180/dim.y, 360/dim.z)$ | size of the grid cells in units of $(r, \theta, \phi)$, per default covering the full sphere; angles in degrees | | OSPData | data | | the actual voxel 3D [data](#data) | | uint | filter | `OSP_VOLUME_FILTER_LINEAR` | filter used for reconstructing the field, also allowed is `OSP_VOLUME_FILTER_NEAREST` | | uint | gradientFilter | same as `filter` | filter used during gradient computations | | float | background | `NaN` | value that is used when sampling an undefined region outside the volume domain | Configuration parameters for structured spherical volumes. The dimensions $(r, \theta, \phi)$ of the volume are inferred from the size of the 3D array `data`, as is the type of the voxel values (currently supported are: `OSP_UCHAR`, `OSP_SHORT`, `OSP_USHORT`, `OSP_HALF`, `OSP_FLOAT`, and `OSP_DOUBLE`). These grid parameters support flexible specification of spheres, hemispheres, spherical shells, spherical wedges, and so forth. The grid extents (computed as `[gridOrigin, gridOrigin + (dimensions - 1) * gridSpacing]`) however must be constrained such that: - $r \geq 0$ - $0 \leq \theta \leq 180$ - $0 \leq \phi \leq 360$ ### Adaptive Mesh Refinement (AMR) Volume OSPRay currently supports block-structured (Berger-Colella) AMR volumes. Volumes are specified as a list of blocks, which exist at levels of refinement in potentially overlapping regions. Blocks exist in a tree structure, with coarser refinement level blocks containing finer blocks. The cell width is equal for all blocks at the same refinement level, though blocks at a coarser level have a larger cell width than finer levels. There can be any number of refinement levels and any number of blocks at any level of refinement. An AMR volume type is created by passing the type string “`amr`†to `ospNewVolume`. Blocks are defined by three parameters: their bounds, the refinement level in which they reside, and the scalar data contained within each block. Note that cell widths are defined *per refinement level*, not per block. | Type | Name | Default | Description | |:------------|:-------------|------------------:|:-----------------------------------------------------------------------------------------------------------------------| | uint | method | `OSP_AMR_CURRENT` | `OSPAMRMethod` sampling method. Supported methods are: | | | | | `OSP_AMR_CURRENT` | | | | | `OSP_AMR_FINEST` | | | | | `OSP_AMR_OCTANT` | | float\[\] | cellWidth | NULL | array of each level’s cell width | | box3i\[\] | block.bounds | NULL | [data](#data) array of grid sizes (in voxels) for each AMR block | | int\[\] | block.level | NULL | array of each block’s refinement level | | OSPData\[\] | block.data | NULL | [data](#data) array of OSPData containing the actual scalar voxel data, only `OSP_FLOAT` is supported as `OSPDataType` | | vec3f | gridOrigin | $(0, 0, 0)$ | origin of the grid | | vec3f | gridSpacing | $(1, 1, 1)$ | size of the grid cells | | float | background | `NaN` | value that is used when sampling an undefined region outside the volume domain | Configuration parameters for AMR volumes. Lastly, note that the `gridOrigin` and `gridSpacing` parameters act just like the structured volume equivalent, but they only modify the root (coarsest level) of refinement. In particular, OSPRay’s / Open VKL’s AMR implementation was designed to cover Berger-Colella \[1\] and Chombo \[2\] AMR data. The `method` parameter above determines the interpolation method used when sampling the volume. OSP_AMR_CURRENT finds the finest refinement level at that cell and interpolates through this “current†level OSP_AMR_FINEST will interpolate at the closest existing cell in the volume-wide finest refinement level regardless of the sample cell’s level OSP_AMR_OCTANT interpolates through all available refinement levels at that cell. This method avoids discontinuities at refinement level boundaries at the cost of performance Details and more information can be found in the publication for the implementation \[3\]. 1. M.J.

DOI: 10.1145/3139295.3139305 ### Unstructured Volume Unstructured volumes can have their topology and geometry freely defined. Geometry can be composed of tetrahedral, hexahedral, wedge or pyramid cell types. The data format used is compatible with VTK and consists of multiple arrays: vertex positions and values, vertex indices, cell start indices, cell types, and cell values. An unstructured volume type is created by passing the type string “`unstructured`†to `ospNewVolume`. Sampled cell values can be specified either per-vertex (`vertex.data`) or per-cell (`cell.data`). If both arrays are set, `cell.data` takes precedence. Similar to a mesh, each cell is formed by a group of indices into the vertices. For each vertex, the corresponding (by array index) data value will be used for sampling when rendering, if specified. The index order for a tetrahedron is the same as `VTK_TETRA`: bottom triangle counterclockwise, then the top vertex. For hexahedral cells, each hexahedron is formed by a group of eight indices into the vertices and data values. Vertex ordering is the same as `VTK_HEXAHEDRON`: four bottom vertices counterclockwise, then top four counterclockwise. For wedge cells, each wedge is formed by a group of six indices into the vertices and data values. Vertex ordering is the same as `VTK_WEDGE`: three bottom vertices counterclockwise, then top three counterclockwise. For pyramid cells, each cell is formed by a group of five indices into the vertices and data values. Vertex ordering is the same as `VTK_PYRAMID`: four bottom vertices counterclockwise, then the top vertex. To maintain VTK data compatibility, the `index` array may be specified with cell sizes interleaved with vertex indices in the following format: $n, id_1, ..., id_n, m, id_1, ..., id_m$. This alternative `index` array layout can be enabled through the `indexPrefixed` flag (in which case, the `cell.type` parameter must be omitted). | Type | Name | Default | Description | |:------------------------|:-------------------|--------:|:--------------------------------------------------------------------------------------------------------------------------------------------------------| | vec3f\[\] | vertex.position | | [data](#data) array of vertex positions | | float\[\] | vertex.data | | [data](#data) array of vertex data values to be sampled | | uint32\[\] / uint64\[\] | index | | [data](#data) array of indices (into the vertex array(s)) that form cells | | bool | indexPrefixed | false | indicates that the `index` array is compatible to VTK, where the indices of each cell are prefixed with the number of vertices | | uint32\[\] / uint64\[\] | cell.index | | [data](#data) array of locations (into the index array), specifying the first index of each cell | | float\[\] | cell.data | | [data](#data) array of cell data values to be sampled | | uint8\[\] | cell.type | | [data](#data) array of cell types (VTK compatible), only set if `indexPrefixed = false`. Supported types are: | | | | | `OSP_TETRAHEDRON` | | | | | `OSP_HEXAHEDRON` | | | | | `OSP_WEDGE` | | | | | `OSP_PYRAMID` | | bool | hexIterative | false | hexahedron interpolation method, defaults to fast non-iterative version which could have rendering inaccuracies may appear if hex is not parallelepiped | | bool | precomputedNormals | false | whether to accelerate by precomputing, at a cost of 12 bytes/face | | float | background | `NaN` | value that is used when sampling an undefined region outside the volume domain | Configuration parameters for unstructured volumes. ### VDB Volume VDB volumes implement a data structure that is very similar to the data structure outlined in Museth \[1\], they are created by passing the type string “`vdb`†to `ospNewVolume`. The data structure is a hierarchical regular grid at its core: Nodes are regular grids, and each grid cell may either store a constant value (this is called a tile), or child pointers. Nodes in VDB trees are wide: Nodes on the first level have a resolution of 323 voxels, on the next level 163, and on the leaf level 83 voxels. All nodes on a given level have the same resolution. This makes it easy to find the node containing a coordinate using shift operations (see \[1\]). VDB leaf nodes are implicit in OSPRay / Open VKL: they are stored as pointers to user-provided data.
Topology of VDB volumes.
VDB volumes interpret input data as constant cells (which are then potentially filtered). This is in contrast to `structuredRegular` volumes, which have a vertex-centered interpretation. The VDB implementation in OSPRay / Open VKL follows the following goals: - Efficient data structure traversal on vector architectures. - Enable the use of industry-standard `.vdb` files created through the OpenVDB library. - Compatibility with OpenVDB on a leaf data level, so that `.vdb` file may be loaded with minimal overhead. VDB volumes have the following parameters: | Type | Name | Description | |:------------|:-----------------|:-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | int | maxSamplingDepth | do not descend further than to this depth during sampling, the maximum value and the default is 3 | | uint32\[\] | node.level | level on which each input node exists, may be 1, 2 or 3 (levels are counted from the root level = 0 down) | | vec3i\[\] | node.origin | the node origin index (per input node) | | OSPData\[\] | node.data | [data](#data) arrays with the node data (per input node). Nodes that are tiles are expected to have single-item arrays. Leaf-nodes with grid data expected to have compact 3D arrays in zyx layout (z changes most quickly) with the correct number of voxels for the `level`. Only `OSP_FLOAT` is supported as field `OSPDataType`. | | OSPData | nodesPackedDense | optionally provided instead of `node.data`, a single array of all dense node data in a contiguous zyx layout, provided in the same order as the corresponding `node.*` parameters | | OSPData | nodesPackedTile | optionally provided instead of `node.data`, a single array of all tile node data in a contiguous layout, provided in the same order as the corresponding `node.*` parameters | | uint32\[\] | node.format | for each input node, whether it is of format `OSP_VOLUME_FORMAT_DENSE_ZYX` (and thus stored in `nodesPackedDense`), or `OSP_VOLUME_FORMAT_TILE` (stored in `nodesPackedTile`) | | uint | filter | filter used for reconstructing the field, default is `OSP_VOLUME_FILTER_LINEAR`, alternatively `OSP_VOLUME_FILTER_NEAREST`, or `OSP_VOLUME_FILTER_CUBIC`. | | uint | gradientFilter | filter used for reconstructing the field during gradient computations, default same as `filter` | | float | background | value that is used when sampling an undefined region outside the volume domain, default `NaN` | Configuration parameters for VDB volumes. The `nodesPackedDense` and `nodesPackedTile` together with `node.format` parameters may be provided instead of `node.data`; this packed data layout may provide better performance. 1. Museth, K. VDB: High-Resolution Sparse Volumes with Dynamic Topology. ACM Transactions on Graphics 32(3), 2013. DOI: 10.1145/2487228.2487235 ### Particle Volume Particle volumes consist of a set of points in space. Each point has a position, a radius, and a weight typically associated with an attribute. Particle volumes are created by passing the type string “`particle`†to `ospNewVolume`. A radial basis function defines the contribution of that particle. Currently, we use the Gaussian radial basis function $$\phi(P) = w \exp\left(-\frac{(P - p)^2}{2 r^2}\right),$$ where $P$ is the particle position, $p$ is the sample position, $r$ is the radius and $w$ is the weight. At each sample, the scalar field value is then computed as the sum of each radial basis function $\phi$, for each particle that overlaps it. The OSPRay / Open VKL implementation is similar to direct evaluation of samples in Reda et al. \[2\]. It uses an Embree-built BVH with a custom traversal, similar to the method in \[1\]. | Type | Name | Default | Description | |:----------|:------------------------|--------:|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | vec3f\[\] | particle.position | | [data](#data) array of particle positions | | float\[\] | particle.radius | | [data](#data) array of particle radii | | float\[\] | particle.weight | NULL | optional [data](#data) array of particle weights, specifying the height of the kernel. | | float | radiusSupportFactor | 3.0 | The multiplier of the particle radius required for support. Larger radii ensure smooth results at the cost of performance. In the Gaussian kernel, the radius is one standard deviation ($\sigma$), so a value of 3 corresponds to $3 \sigma$. | | float | clampMaxCumulativeValue | 0 | The maximum cumulative value possible, set by user. All cumulative values will be clamped to this, and further traversal (RBF summation) of particle contributions will halt when this value is reached. A value of zero or less turns this off. | | bool | estimateValueRanges | true | Enable heuristic estimation of value ranges which are used in internal acceleration structures as well as for determining the volume’s overall value range. When set to `false`, the user *must* specify `clampMaxCumulativeValue`, and all value ranges will be assumed \[0–`clampMaxCumulativeValue`\]. Disabling this switch may improve volume commit time, but will make volume rendering less efficient. | Configuration parameters for particle volumes. 1. A. Knoll, I. Wald, P. Navratil, A. Bowen, K.

To create a new transfer function of given type `type` use ``` cpp OSPTransferFunction ospNewTransferFunction(const char *type); ``` The returned handle can be assigned to a volumetric model (described below) as parameter “`transferFunction`†using `ospSetObject`. One type of transfer function that is supported by OSPRay is the linear transfer function, which interpolates between given equidistant colors and opacities. It is create by passing the string “`piecewiseLinear`†to `ospNewTransferFunction` and it is controlled by these parameters: | Type | Name | Description | |:----------|:--------|:----------------------------------------------| | vec3f\[\] | color | [data](#data) array of colors (linear RGB) | | float\[\] | opacity | [data](#data) array of opacities | | box1f | value | domain (scalar range) this function maps from | Parameters accepted by the linear transfer function. The arrays `color` and `opacity` can be of different length. ### VolumetricModels Volumes in OSPRay are given volume rendering appearance information through VolumetricModels. This decouples the physical representation of the volume (and possible acceleration structures it contains) to rendering-specific parameters (where more than one set may exist concurrently). To create a volume instance, call ``` cpp OSPVolumetricModel ospNewVolumetricModel(OSPVolume); ``` The passed volume can be `NULL` as long as the volume to be used is passed as a parameter. If both a volume is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the volume object passed on object creation is again used. | Type | Name | Default | Description | |:--------------------|:-----------------|--------:|:-------------------------------------------------------------------------------------------------------------------------------------| | OSPVolume | volume | | optional [volume](#volumes) object this model references | | OSPTransferFunction | transferFunction | | [transfer function](#transfer-function) to use | | float | densityScale | 1.0 | makes volumes uniformly thinner or thicker | | float | anisotropy | 0.0 | anisotropy of the (Henyey-Greenstein) phase function in \[-1–1\] ([path tracer](#path-tracer) only), default to isotropic scattering | | uint32 | id | -1u | optional user ID, for [framebuffer](#framebuffer) channel `OSP_FB_ID_OBJECT` | Parameters understood by VolumetricModel. Geometries ---------- Geometries in OSPRay are objects that describe intersectable surfaces. To create a new geometry object of given type `type` use ``` cpp OSPGeometry ospNewGeometry(const char *type); ``` Note that in the current implementation geometries are limited to a maximum of 232 primitives. ### Mesh A mesh consisting of either triangles or quads is created by calling `ospNewGeometry` with type string “`mesh`â€. Once created, a mesh recognizes the following parameters: | Type | Name | Description | |:------------------------|:-----------------------|:---------------------------------------------------------------------------------------------------------------------| | vec3f\[\] | vertex.position | [data](#data) array of vertex positions, overridden by `motion.*` arrays | | vec3f\[\] | normal | [data](#data) array of face-varying normals, overridden by `motion.*` arrays | | vec3f\[\] | vertex.normal | [data](#data) array of vertex-varying normals, overridden by `motion.*` arrays | | vec4f\[\] / vec3f\[\] | color | [data](#data) array of face-varying colors (linear RGBA/RGB) | | vec4f\[\] / vec3f\[\] | vertex.color | [data](#data) array of vertex-varying colors (linear RGBA/RGB) | | vec2f\[\] | texcoord | [data](#data) array of face-varying texture coordinates | | vec2f\[\] | vertex.texcoord | [data](#data) array of vertex-varying texture coordinates | | vec3ui\[\] / vec4ui\[\] | index | [data](#data) array of (either triangle or quad) indices (into the vertex array(s)) | | bool | quadSoup | when no explicit `index` is given, indicates whether to assume a ‘soup’ of quads instead of triangles, default false | | vec3f\[\]\[\] | motion.vertex.position | [data](#data) array of vertex position arrays (uniformly distributed keys for deformation motion blur) | | vec3f\[\]\[\] | motion.normal | [data](#data) array of face-varying normal arrays (uniformly distributed keys for deformation motion blur) | | vec3f\[\]\[\] | motion.vertex.normal | [data](#data) array of vertex-varying normal arrays (uniformly distributed keys for deformation motion blur) | | box1f | time | time associated with first and last key in `motion.*` arrays (for deformation motion blur), default \[0, 1\] | Parameters defining a mesh geometry. The data type of index arrays differentiates between the underlying geometry, triangles are used for a index with `vec3ui` type and quads for `vec4ui` type. Quads are internally handled as a pair of two triangles, thus mixing triangles and quads is supported by encoding some triangle as a quad with the last two vertex indices being identical (`w=z`). The `vertex.position` array is mandatory to create a valid mesh. The `index` array is optional. If none is provided, a ‘triangle soup’ is assumed, i.e., each three consecutive vertices form one triangle; unless the boolean `quadSoup` is set to true, then a ‘quad soup’ is assumed i.e., each four subsequent vertices form one quad. If the size of the `vertex.position` array is not a multiple of three for triangles or four for quads, the remainder vertices are ignored. Face-varying attributes (`normal`, `motion.normal`, `color`, `texcoord`) map unique values to each vertex of a primitive/face (triangle or quad), thus attributes can be different for the same vertex that is shared by multiple primitives. Essentially, face-varying attributes are a ‘attribute soup’ and behave similar to the implicit index, the size of the array must be at least three times the number of triangles or four times the number of quads, respectively. Face-varying attributes take precedence over the respective vertex attributes (`vertex.normal`, `motion.vertex.normal`, `vertex.color`, `vertex.texcoord`) when both arrays of the same attribute are present. ### Subdivision A mesh consisting of subdivision surfaces, created by specifying a geometry of type “`subdivision`â€. Once created, a subdivision recognizes the following parameters: | Type | Name | Description | |:----------|:--------------------|:----------------------------------------------------------------------------------------------------------------------| | vec3f\[\] | vertex.position | [data](#data) array of vertex positions | | vec4f\[\] | color | optional [data](#data) array of face-varying colors (linear RGBA) | | vec4f\[\] | vertex.color | optional [data](#data) array of vertex-varying colors (linear RGBA) | | vec2f\[\] | texcoord | optional [data](#data) array of vertex-varying texture coordinates | | vec2f\[\] | vertex.texcoord | optional [data](#data) array of vertex-varying texture coordinates | | float | level | global level of tessellation, default 5 | | uint\[\] | index | [data](#data) array of indices (into the vertex array(s)) | | float\[\] | index.level | optional [data](#data) array of per-edge levels of tessellation, overrides global level | | uint\[\] | face | optional [data](#data) array holding the number of indices/edges (3 to 15) per face, defaults to 4 (a pure quad mesh) | | vec2i\[\] | edgeCrease.index | optional [data](#data) array of edge crease indices | | float\[\] | edgeCrease.weight | optional [data](#data) array of edge crease weights | | uint\[\] | vertexCrease.index | optional [data](#data) array of vertex crease indices | | float\[\] | vertexCrease.weight | optional [data](#data) array of vertex crease weights | | uint | mode | `OSPSubdivisionMode` subdivision edge boundary mode, supported modes are: | | | | `OSP_SUBDIVISION_NO_BOUNDARY` | | | | `OSP_SUBDIVISION_SMOOTH_BOUNDARY` (default) | | | | `OSP_SUBDIVISION_PIN_CORNERS` | | | | `OSP_SUBDIVISION_PIN_BOUNDARY` | | | | `OSP_SUBDIVISION_PIN_ALL` | Parameters defining a Subdivision geometry. The `vertex` and `index` arrays are mandatory to create a valid subdivision surface. If no `face` array is present then a pure quad mesh is assumed (the number of indices must be a multiple of 4). Optionally supported are edge and vertex creases. ### Spheres A geometry consisting of individual spheres, each of which can have an own radius, is created by calling `ospNewGeometry` with type string “`sphere`â€. The spheres will not be tessellated but rendered procedurally and are thus perfectly round. To allow a variety of sphere representations in the application this geometry allows a flexible way of specifying the data of center position and radius within a [data](#data) array: | Type | Name | Default | Description | |:----------|:----------------|--------:|:--------------------------------------------------------------------------| | vec3f\[\] | sphere.position | | [data](#data) array of center positions | | float\[\] | sphere.radius | NULL | optional [data](#data) array of the per-sphere radius | | vec3f\[\] | sphere.normal | NULL | optional [data](#data) array of normals (only for “oriented discâ€) | | vec2f\[\] | sphere.texcoord | NULL | optional [data](#data) array of texture coordinates (constant per sphere) | | float | radius | 0.01 | default radius for all spheres (if `sphere.radius` is not set) | | uint | type | | `OSPSphereType` for rendering the sphere. Supported types are: | | | | | `OSP_SPHERE` (default) | | | | | `OSP_DISC` | | | | | `OSP_ORIENTED_DISC` | Parameters defining a spheres geometry. ### Curves A geometry consisting of multiple curves is created by calling `ospNewGeometry` with type string “`curve`â€. The parameters defining this geometry are listed in the table below. | Type | Name | Description | |:-----------|:-----------------------|:---------------------------------------------------------------------------------| | vec4f\[\] | vertex.position_radius | [data](#data) array of vertex position and per-vertex radius | | vec2f\[\] | vertex.texcoord | [data](#data) array of per-vertex texture coordinates | | vec4f\[\] | vertex.color | [data](#data) array of corresponding vertex colors (linear RGBA) | | vec3f\[\] | vertex.normal | [data](#data) array of curve normals (only for “ribbon†curves) | | vec4f\[\] | vertex.tangent | [data](#data) array of curve tangents (only for “hermite†curves) | | uint32\[\] | index | [data](#data) array of indices to the first vertex or tangent of a curve segment | | uint | type | `OSPCurveType` for rendering the curve. Supported types are: | | | | `OSP_FLAT` | | | | `OSP_ROUND` | | | | `OSP_RIBBON` | | | | `OSP_DISJOINT` | | uint | basis | `OSPCurveBasis` for defining the curve. Supported bases are: | | | | `OSP_LINEAR` | | | | `OSP_BEZIER` | | | | `OSP_BSPLINE` | | | | `OSP_HERMITE` | | | | `OSP_CATMULL_ROM` | Parameters defining a curves geometry. Positions in `vertex.position_radius` parameter supports per-vertex varying radii with data type `vec4f[]` and instantiate Embree curves internally for the relevant type/basis mapping. The following section describes the properties of different curve basis’ and how they use the data provided in data buffers: OSP_LINEAR The indices point to the first of 2 consecutive control points in the vertex buffer. The first control point is the start and the second control point the end of the line segment. The curve goes through all control points listed in the vertex buffer. OSP_BEZIER The indices point to the first of 4 consecutive control points in the vertex buffer. The first control point represents the start point of the curve, and the 4th control point the end point of the curve. The Bézier basis is interpolating, thus the curve does go exactly through the first and fourth control vertex. OSP_BSPLINE The indices point to the first of 4 consecutive control points in the vertex buffer. This basis is not interpolating, thus the curve does in general not go through any of the control points directly. Using this basis, 3 control points can be shared for two continuous neighboring curve segments, e.g., the curves $(p0, p1, p2, p3)$ and $(p1, p2, p3, p4)$ are C1 continuous. This feature make this basis a good choice to construct continuous multi-segment curves, as memory consumption can be kept minimal. OSP_HERMITE It is necessary to have both vertex buffer and tangent buffer for using this basis. The indices point to the first of 2 consecutive points in the vertex buffer, and the first of 2 consecutive tangents in the tangent buffer. This basis is interpolating, thus does exactly go through the first and second control point, and the first order derivative at the begin and end matches exactly the value specified in the tangent buffer. When connecting two segments continuously, the end point and tangent of the previous segment can be shared. OSP_CATMULL_ROM The indices point to the first of 4 consecutive control points in the vertex buffer. If $(p0, p1, p2, p3)$ represent the points then this basis goes through $p1$ and $p2$, with tangents as $(p2-p0)/2$ and $(p3-p1)/2$. The following section describes the properties of different curve types’ and how they define the geometry of a curve: OSP_FLAT This type enables faster rendering as the curve is rendered as a connected sequence of ray facing quads. OSP_ROUND This type enables rendering a real geometric surface for the curve which allows closeup views. This mode renders a sweep surface by sweeping a varying radius circle tangential along the curve. OSP_RIBBON The type enables normal orientation of the curve and requires a normal buffer be specified along with vertex buffer. The curve is rendered as a flat band whose center approximately follows the provided vertex buffer and whose normal orientation approximately follows the provided normal buffer. Not supported for basis `OSP_LINEAR`. OSP_DISJOINT Only supported for basis `OSP_LINEAR`; the segments are open and not connected at the joints, i.e., the curve segments are either individual cones or cylinders. ### Boxes OSPRay can directly render axis-aligned bounding boxes without the need to convert them to quads or triangles. To do so create a boxes geometry by calling `ospNewGeometry` with type string “`box`â€. | Type | Name | Description | |:----------|:-----|:-----------------------------| | box3f\[\] | box | [data](#data) array of boxes | Parameters defining a boxes geometry. ### Planes OSPRay can directly render planes defined by plane equation coefficients in its implicit form $ax + by + cz + d = 0$. By default planes are infinite but their extents can be limited by defining optional bounding boxes. A planes geometry can be created by calling `ospNewGeometry` with type string “`plane`â€. | Type | Name | Description | |:----------|:-------------------|:---------------------------------------------------------| | vec4f\[\] | plane.coefficients | [data](#data) array of plane coefficients $(a, b, c, d)$ | | box3f\[\] | plane.bounds | optional [data](#data) array of bounding boxes | Parameters defining a planes geometry. ### Isosurfaces OSPRay can directly render multiple isosurfaces of a volume without first tessellating them. To do so create an isosurfaces geometry by calling `ospNewGeometry` with type string “`isosurface`â€. The appearance information of the surfaces is set through the Geometric Model. Per-isosurface colors can be set by passing per-primitive colors to the Geometric Model, in order of the isosurface array. | Type | Name | Description | |:----------|:---------|:---------------------------------------------------| | float | isovalue | single isovalues | | float\[\] | isovalue | [data](#data) array of isovalues | | OSPVolume | volume | handle of the [Volume](#volumes) to be isosurfaced | Parameters defining an isosurfaces geometry. ### GeometricModels Geometries are matched with surface appearance information through GeometricModels. These take a geometry, which defines the surface representation, and applies either full-object or per-primitive color and material information. To create a geometric model, call ``` cpp OSPGeometricModel ospNewGeometricModel(OSPGeometry); ``` The passed geometry can be `NULL` as long as the geometry to be used is passed as a parameter. If both a geometry is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the geometry object passed on object creation is again used. Color and material are fetched with the primitive ID of the hit (clamped to the valid range, thus a single color or material is fine), or mapped first via the `index` array (if present). All parameters are optional, however, some renderers (notably the [path tracer](#path-tracer)) require a material to be set. Materials are either handles of `OSPMaterial`, or indices into the `material` array on the [renderer](#renderers), which allows to build a [world](#world) which can be used by different types of renderers. An `invertNormals` flag allows to invert (shading) normal vectors of the rendered geometry. That is particularly useful for clipping. By changing normal vectors orientation one can control whether inside or outside of the clipping geometry is being removed. For example, a clipping geometry with normals oriented outside clips everything what’s inside. | Type | Name | Description | |:----------------------------------------------------|:--------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------| | OSPGeometry | geometry | optional [geometry](#geometries) object this model references | | OSPMaterial / OSPMaterial\[\] / uint32 / uint32\[\] | material | optional ([data](#data) array of per-primitive) [material](#materials), may be an index into the `material` parameter on the renderer (if it exists) | | vec4f / vec4f\[\] | color | optional ([data](#data) array of per-primitive) color assigned to the geometry (linear RGBA) | | uint8\[\] | index | optional [data](#data) array of per-primitive indices into `color` and `material` | | bool | invertNormals | inverts all shading normals (Ns), default false | | uint32 | id | optional user ID, for [framebuffer](#framebuffer) channel `OSP_FB_ID_OBJECT`, default -1u | Parameters understood by GeometricModel. Lights ------ To create a new light source of given type `type` use ``` cpp OSPLight ospNewLight(const char *type); ``` All light sources accept the following parameters: | Type | Name | Default | Description | |:------|:------------------|--------:|:----------------------------------------------------------------------------------------------------------------------------------| | vec3f | color | white | color of the light (linear RGB) | | float | intensity | 1 | intensity of the light (a factor) | | uint | intensityQuantity | | `OSPIntensityQuantity` to set the radiometric quantity represented by `intensity`. The default value depends on the light source. | | bool | visible | true | whether the light can be directly seen | Parameters accepted by all lights. In OSPRay the `intensity` parameter of a light source can correspond to different types of radiometric quantities. The type of the value represented by a light’s `intensity` parameter is set using `intensityQuantity`, which accepts values from the enum type `OSPIntensityQuantity`. The supported types of `OSPIntensityQuantity` differ between the different light sources (see documentation of each specific light source). | Name | Description | |:----------------------------------|:---------------------------------------------------------------------------------------------------------------------------------------| | OSP_INTENSITY_QUANTITY_POWER | the overall amount of light energy emitted by the light source into the scene, unit is W | | OSP_INTENSITY_QUANTITY_INTENSITY | the overall amount of light emitted by the light in a given direction, unit is W/sr | | OSP_INTENSITY_QUANTITY_RADIANCE | the amount of light emitted by a point on the light source in a given direction, unit is W/sr/m2 | | OSP_INTENSITY_QUANTITY_IRRADIANCE | the amount of light arriving at a surface point, assuming the light is oriented towards to the surface, unit is W/m2 | | OSP_INTENSITY_QUANTITY_SCALE | a linear scaling factor for light sources with a built-in quantity (e.g., `HDRI`, or `sunSky`, or when using `intensityDistribution`). | Types of radiometric quantities used to interpret a light’s `intensity` parameter. ### Photometric Lights Measured light sources (IES, EULUMDAT, …) are supported by the `sphere`, `spot`, and `quad` lights when setting an `intensityDistribution` [data](#data) array to modulate the intensity per direction. The mapping is using the C-γ coordinate system (see also below figure): the values of the first (or only) dimension of `intensityDistribution` are uniformly mapped to γ in \[0–π\]; the first intensity value to 0, the last value to Ï€, thus at least two values need to be present. ![C-γ coordinate system for the mapping of `intensityDistribution` with photometric lights.](https://ospray.github.io/images/c-gamma_coords.png) If the array has a second dimension then the intensities are not rotational symmetric around the main direction (where angle γ is zero), but are accordingly mapped to the C-halfplanes in \[0–2Ï€\]; the first “row†of values to 0 and 2Ï€, the other rows such that they have uniform distance to its neighbors. The orientation of the C0-plane is specified via `c0`. | Type | Name | Description | |:----------|:----------------------|:----------------------------------------------------------------------------------------------------------------------------------------------| | float\[\] | intensityDistribution | luminous intensity distribution for photometric lights; can be 2D for asymmetric illumination; values are assumed to be uniformly distributed | | vec3f | c0 | orientation, i.e., direction of the C0-(half)plane (only needed if illumination via `intensityDistribution` is asymmetric) | Special parameters for photometric lights. When using an `intensityDistribution` then the default and only valid value for `intensityQuantity` is `OSP_INTENSITY_QUANTITY_SCALE`. The following light types are supported by most OSPRay renderers. ### Directional Light / Distant Light The distant light (or traditionally the directional light) is thought to be far away (outside of the scene), thus its light arrives (almost) as parallel rays. It is created by passing the type string “`distant`†to `ospNewLight`. The distant light supports `OSP_INTENSITY_QUANTITY_RADIANCE` and `OSP_INTENSITY_QUANTITY_IRRADIANCE` (default) as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights the distant light supports the following special parameters: | Type | Name | Default | Description | |:------|:----------------|------------:|:---------------------------------------------| | vec3f | direction | $(0, 0, 1)$ | main emission direction of the distant light | | float | angularDiameter | 0 | apparent size (angle in degree) of the light | Special parameters accepted by the distant light. Setting the angular diameter to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer](#path-tracer)). For instance, the apparent size of the sun is about 0.53°. ### Point Light / Sphere Light The sphere light (or the special case point light) is a light emitting uniformly in all directions from the surface toward the outside. It does not emit any light toward the inside of the sphere. It is created by passing the type string “`sphere`†to `ospNewLight`. The point light supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` (then default) and `OSP_INTENSITY_QUANTITY_RADIANCE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the sphere light supports the following special parameters: | Type | Name | Default | Description | |:------|:----------|------------:|:--------------------------------------------| | vec3f | position | $(0, 0, 0)$ | the center of the sphere light | | float | radius | 0 | the size of the sphere light | | vec3f | direction | $(0, 0, 1)$ | main orientation of `intensityDistribution` | Special parameters accepted by the sphere light. Setting the radius to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer](#path-tracer)). ### Spotlight / Ring Light The spotlight is a light emitting into a cone of directions. It is created by passing the type string “`spot`†to `ospNewLight`. The spotlight supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` (then default) and `OSP_INTENSITY_QUANTITY_RADIANCE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the spotlight supports the special parameters listed in the table. | Type | Name | Default | Description | |:------|:--------------|------------:|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | vec3f | position | $(0, 0, 0)$ | the center of the spotlight | | vec3f | direction | $(0, 0, 1)$ | main emission direction of the spot | | float | openingAngle | 180 | full opening angle (in degree) of the spot; outside of this cone is no illumination | | float | penumbraAngle | 5 | size (angle in degree) of the “penumbraâ€, the region between the rim (of the illumination cone) and full intensity of the spot; should be smaller than half of `openingAngle` | | float | radius | 0 | the size of the spotlight, the radius of a disk with normal `direction` | | float | innerRadius | 0 | in combination with `radius` turns the disk into a ring | Special parameters accepted by the spotlight. ![Angles used by the spotlight.](https://ospray.github.io/images/spot_light.png) Setting the radius to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer](#path-tracer)). Additionally setting the inner radius will result in a ring instead of a disk emitting the light. ### Quad Light The quad[^4] light is a planar, procedural area light source emitting uniformly on one side into the half-space. It is created by passing the type string “`quad`†to `ospNewLight`. The quad light supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` and `OSP_INTENSITY_QUANTITY_RADIANCE` (then default) as `intensityQuantity` parameter. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the quad light supports the following special parameters: | Type | Name | Default | Description | |:------|:---------|------------:|:-----------------------------------------| | vec3f | position | $(0, 0, 0)$ | position of one vertex of the quad light | | vec3f | edge1 | $(1, 0, 0)$ | vector to one adjacent vertex | | vec3f | edge2 | $(0, 1, 0)$ | vector to the other adjacent vertex | Special parameters accepted by the quad light. ![Defining a quad light which emits toward the reader.](https://ospray.github.io/images/quad_light.png) The emission side is determined by the cross product of `edge1`×`edge2`. which is also the main emission direction for `intensityDistribution`. Note that only renderers that use stochastic sampling (like the path tracer) will compute soft shadows from the quad light. Other renderers will just sample the center of the quad light, which results in hard shadows. ### Cylinder Light The cylinder light is a cylinderical, procedural area light source emitting uniformly outwardly into the space beyond the boundary. It is created by passing the type string “`cylinder`†to `ospNewLight`. The cylinder light supports `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` and `OSP_INTENSITY_QUANTITY_RADIANCE` (default) as `intensityQuantity` parameter. In addition to the [general parameters](#lights) understood by all lights the cylinder light supports the following special parameters: | Type | Name | Default | Description | |:------|:----------|------------:|:--------------------------------------| | vec3f | position0 | $(0, 0, 0)$ | position of the start of the cylinder | | vec3f | position1 | $(0, 0, 1)$ | position of the end of the cylinder | | float | radius | 1 | radius of the cylinder | Special parameters accepted by the cylinder light. Note that only renderers that use stochastic sampling (like the path tracer) will compute soft shadows from the cylinder light. Other renderers will just sample the closest point on the cylinder light, which results in hard shadows. ### HDRI Light The HDRI light is a textured light source surrounding the scene and illuminating it from infinity. It is created by passing the type string “`hdri`†to `ospNewLight`. The values of the HDRI correspond to radiance and therefore the HDRI light only accepts `OSP_INTENSITY_QUANTITY_SCALE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) the HDRI light supports the following special parameters: | Type | Name | Default | Description | |:-----------|:----------|------------:|:-----------------------------------------------------------------------------------------------------------------| | vec3f | up | $(0, 1, 0)$ | up direction of the light | | vec3f | direction | $(0, 0, 1)$ | direction to which the center of the texture will be mapped to (analog to [panoramic camera](#panoramic-camera)) | | OSPTexture | map | | environment map in latitude / longitude format | Special parameters accepted by the HDRI light. ![Orientation and Mapping of an HDRI Light.](https://ospray.github.io/images/hdri_light.png) Note that the [SciVis renderer](#scivis-renderer) only shows the HDRI light in the background (like an environment map) without computing illumination of the scene. ### Ambient Light The ambient light surrounds the scene and illuminates it from infinity with constant radiance (determined by combining the [parameters `color` and `intensity`](#lights)). It is created by passing the type string “`ambient`†to `ospNewLight`. The ambient light supports `OSP_INTENSITY_QUANTITY_RADIANCE` and `OSP_INTENSITY_QUANTITY_IRRADIANCE` (default) as `intensityQuantity` parameter value. Note that the [SciVis renderer](#scivis-renderer) uses ambient lights to control the color and intensity of the computed ambient occlusion (AO). ### Sun-Sky Light The sun-sky light is a combination of a `distant` light for the sun and a procedural `hdri` light for the sky. It is created by passing the type string “`sunSky`†to `ospNewLight`. The sun-sky light surrounds the scene and illuminates it from infinity and can be used for rendering outdoor scenes. The radiance values are calculated using the HoÅ¡ek-Wilkie sky model and solar radiance function. The underlying model of the sun-sky light returns radiance values and therefore the light only accepts `OSP_INTENSITY_QUANTITY_SCALE` as `intensityQuantity` parameter value. To rescale the returned radiance of the sky model the default value for the `intensity` parameter is set to `0.025`. In addition to the [general parameters](#lights) the following special parameters are supported: | Type | Name | Default | Description | |:------|:-----------------|-------------:|:-----------------------------------------------------------------------------------------------------| | vec3f | up | $(0, 1, 0)$ | zenith of sky | | vec3f | direction | $(0, -1, 0)$ | main emission direction of the sun | | float | turbidity | 3 | atmospheric turbidity due to particles, in \[1–10\] | | float | albedo | 0.3 | ground reflectance, in \[0–1\] | | float | horizonExtension | 0.01 | extend the sky dome by stretching the horizon, fraction of the lower hemisphere to cover, in \[0–1\] | Special parameters accepted by the `sunSky` light. The lowest elevation for the sun is restricted to the horizon. Note that the [SciVis renderer](#scivis-renderer) only computes illumination from the sun (yet the sky is still shown in the background, like an environment map). ### Emissive Objects The [path tracer](#path-tracer) will consider illumination by [geometries](#geometries) which have a light emitting material assigned (for example the [Luminous](#luminous) or [Principled](#principled) material). Materials --------- Materials describe how light interacts with surfaces, they give objects their distinctive look. To create a new material of given type `type` call ``` cpp OSPMaterial ospNewMaterial(const char *material_type); ``` The returned handle can then be used to assign the material to a given geometry with ``` cpp void ospSetObject(OSPGeometricModel, "material", OSPMaterial); ``` ### OBJ Material The OBJ material is the workhorse material supported by both the [SciVis renderer](#scivis-renderer) and the [path tracer](#path-tracer) (the [Ambient Occlusion renderer](#ambient-occlusion-renderer) only uses the `kd` and `d` parameter). It offers widely used common properties like diffuse and specular reflection and is based on the [MTL material format](http://paulbourke.net/dataformats/mtl/) of Lightwave’s OBJ scene files. To create an OBJ material pass the type string “`obj`†to `ospNewMaterial`. Its main parameters are | Type | Name | Default | Description | |:-----------|:---------|----------:|:------------------------------------------------------------| | vec3f | kd | white 0.8 | diffuse color (linear RGB) | | vec3f | ks | black | specular color (linear RGB) | | float | ns | 10 | shininess (Phong exponent), usually in \[2–104\] | | float | d | opaque | opacity | | vec3f | tf | black | transparency filter color (linear RGB) | | OSPTexture | map_bump | NULL | normal map | Main parameters of the OBJ material. In particular when using the path tracer it is important to adhere to the principle of energy conservation, i.e., that the amount of light reflected by a surface is not larger than the light arriving. Therefore the path tracer issues a warning and renormalizes the color parameters if the sum of `kd`, `ks`, and `tf` is larger than one in any color channel. Similarly important to mention is that almost all materials of the real world reflect at most only about 80% of the incoming light. So even for a white sheet of paper or white wall paint do better not set `kd` larger than 0.8; otherwise rendering times are unnecessary long and the contrast in the final images is low (for example, the corners of a white room would hardly be discernible, as can be seen in the figure below).
Comparison of diffuse rooms with 100% reflecting white paint (left) and realistic 80% reflecting white paint (right), which leads to higher overall contrast. Note that exposure has been adjusted to achieve similar brightness levels.
If present, the color component of [geometries](#geometries) is also used for the diffuse color `kd` and the alpha component is also used for the opacity `d`. Normal mapping can simulate small geometric features via the texture `map_bump`. The normals $n$ in the normal map are with respect to the local tangential shading coordinate system and are encoded as $½(n+1)$, thus a texel $(0.5, 0.5, 1)$[^5] represents the unperturbed shading normal $(0, 0, 1)$. Because of this encoding an sRGB gamma [texture](#texture) format is ignored and normals are always fetched as linear from a normal map. Note that the orientation of normal maps is important for a visually consistent look: by convention OSPRay uses a coordinate system with the origin in the lower left corner; thus a convexity will look green toward the top of the texture image (see also the example image of a normal map). If this is not the case flip the normal map vertically or invert its green channel.
Normal map representing an exalted square pyramidal frustum.
Note that `tf` colored transparency is implemented in the SciVis and the path tracer but normal mapping with `map_bump` is currently supported in the path tracer only. All parameters (except `tf`) can be textured by passing a [texture](#texture) handle, prefixed with “`map_`â€. The fetched texels are multiplied by the respective parameter value. If only the texture is given (but not the corresponding parameter), only the texture is used (the default value of the parameter is *not* multiplied). The color textures `map_kd` and `map_ks` are typically in one of the sRGB gamma encoded formats, whereas textures `map_ns` and `map_d` are usually in a linear format (and only the first component is used). Additionally, all textures support [texture transformations](#texture-transformations).

### Principled The Principled material is the most complex material offered by the [path tracer](#path-tracer), which is capable of producing a wide variety of materials (e.g., plastic, metal, wood, glass) by combining multiple different layers and lobes. It uses the GGX microfacet distribution with approximate multiple scattering for dielectrics and metals, uses the Oren-Nayar model for diffuse reflection, and is energy conserving. To create a Principled material, pass the type string “`principled`†to `ospNewMaterial`. Its parameters are listed in the table below. | Type | Name | Default | Description | |:------|:------------------|----------:|:------------------------------------------------------------------------------------------------------------------------| | vec3f | baseColor | white 0.8 | base reflectivity (diffuse and/or metallic, linear RGB) | | vec3f | edgeColor | white | edge tint (metallic only, linear RGB) | | float | metallic | 0 | mix between dielectric (diffuse and/or specular) and metallic (specular only with complex IOR) in \[0–1\] | | float | diffuse | 1 | diffuse reflection weight in \[0–1\] | | float | specular | 1 | specular reflection/transmission weight in \[0–1\] | | float | ior | 1 | dielectric index of refraction | | float | transmission | 0 | specular transmission weight in \[0–1\] | | vec3f | transmissionColor | white | attenuated color due to transmission (Beer’s law, linear RGB) | | float | transmissionDepth | 1 | distance at which color attenuation is equal to transmissionColor | | float | roughness | 0 | diffuse and specular roughness in \[0–1\], 0 is perfectly smooth | | float | anisotropy | 0 | amount of specular anisotropy in \[0–1\] | | float | rotation | 0 | rotation of the direction of anisotropy in \[0–1\], 1 is going full circle | | float | normal | 1 | default normal map/scale for all layers | | float | baseNormal | 1 | base normal map/scale (overrides default normal) | | bool | thin | false | flag specifying whether the material is thin or solid | | float | thickness | 1 | thickness of the material (thin only), affects the amount of color attenuation due to specular transmission | | float | backlight | 0 | amount of diffuse transmission (thin only) in \[0–2\], 1 is 50% reflection and 50% transmission, 2 is transmission only | | float | coat | 0 | clear coat layer weight in \[0–1\] | | float | coatIor | 1.5 | clear coat index of refraction | | vec3f | coatColor | white | clear coat color tint (linear RGB) | | float | coatThickness | 1 | clear coat thickness, affects the amount of color attenuation | | float | coatRoughness | 0 | clear coat roughness in \[0–1\], 0 is perfectly smooth | | float | coatNormal | 1 | clear coat normal map/scale (overrides default normal) | | float | sheen | 0 | sheen layer weight in \[0–1\] | | vec3f | sheenColor | white | sheen color tint (linear RGB) | | float | sheenTint | 0 | how much sheen is tinted from sheenColor toward baseColor | | float | sheenRoughness | 0.2 | sheen roughness in \[0–1\], 0 is perfectly smooth | | float | opacity | 1 | cut-out opacity/transparency, 1 is fully opaque | | vec3f | emissiveColor | black | color (and intensity) of the emitted light | Parameters of the Principled material. All parameters can be textured by passing a [texture](#texture) handle, prefixed with “`map_`†(e.g., “`map_baseColor`â€). [texture transformations](#texture-transformations) are supported as well.

### CarPaint The CarPaint material is a specialized version of the Principled material for rendering different types of car paints. To create a CarPaint material, pass the type string “`carPaint`†to `ospNewMaterial`. Its parameters are listed in the table below. | Type | Name | Default | Description | |:------|:----------------|----------:|:-----------------------------------------------------------------------------------------------------------------------| | vec3f | baseColor | white 0.8 | diffuse base reflectivity (linear RGB) | | float | roughness | 0 | diffuse roughness in \[0–1\], 0 is perfectly smooth | | float | normal | 1 | normal map/scale | | vec3f | flakeColor | Aluminium | color of metallic flakes (linear RGB) | | float | flakeDensity | 0 | density of metallic flakes in \[0–1\], 0 disables flakes, 1 fully covers the surface with flakes | | float | flakeScale | 100 | scale of the flake structure, higher values increase the amount of flakes | | float | flakeSpread | 0.3 | flake spread in \[0–1\] | | float | flakeJitter | 0.75 | flake randomness in \[0–1\] | | float | flakeRoughness | 0.3 | flake roughness in \[0–1\], 0 is perfectly smooth | | float | coat | 1 | clear coat layer weight in \[0–1\] | | float | coatIor | 1.5 | clear coat index of refraction | | vec3f | coatColor | white | clear coat color tint (linear RGB) | | float | coatThickness | 1 | clear coat thickness, affects the amount of color attenuation | | float | coatRoughness | 0 | clear coat roughness in \[0–1\], 0 is perfectly smooth | | float | coatNormal | 1 | clear coat normal map/scale | | vec3f | flipflopColor | white | reflectivity of coated flakes at grazing angle, used together with coatColor produces a pearlescent paint (linear RGB) | | float | flipflopFalloff | 1 | flip flop color falloff, 1 disables the flip flop effect | Parameters of the CarPaint material. All parameters can be textured by passing a [texture](#texture) handle, prefixed with “`map_`†(e.g., “`map_baseColor`â€). [texture transformations](#texture-transformations) are supported as well.

### Metal The [path tracer](#path-tracer) offers a physical metal, supporting changing roughness and realistic color shifts at edges. To create a Metal material pass the type string “`metal`†to `ospNewMaterial`. Its parameters are | Type | Name | Default | Description | |:----------|:----------|----------:|:---------------------------------------------------------------------------------------------------------------------------------------------------------| | vec3f\[\] | ior | Aluminium | [data](#data) array of spectral samples of complex refractive index, each entry in the form (wavelength, eta, k), ordered by wavelength (which is in nm) | | vec3f | eta | | RGB complex refractive index, real part | | vec3f | k | | RGB complex refractive index, imaginary part | | float | roughness | 0.1 | roughness in \[0–1\], 0 is perfect mirror | Parameters of the Metal material. The main appearance (mostly the color) of the Metal material is controlled by the physical parameters `eta` and `k`, the wavelength-dependent, complex index of refraction. These coefficients are quite counter-intuitive but can be found in [published measurements](https://refractiveindex.info/). For accuracy the index of refraction can be given as an array of spectral samples in `ior`, each sample a triplet of wavelength (in nm), eta, and k, ordered monotonically increasing by wavelength; OSPRay will then calculate the Fresnel in the spectral domain. Alternatively, `eta` and `k` can also be specified as approximated RGB coefficients; some examples are given in below table. | Metal | eta | k | |:--------------|:---------------------:|:---------------:| | Ag, Silver | (0.051, 0.043, 0.041) | (5.3, 3.6, 2.3) | | Al, Aluminium | (1.5, 0.98, 0.6) | (7.6, 6.6, 5.4) | | Au, Gold | (0.07, 0.37, 1.5) | (3.7, 2.3, 1.7) | | Cr, Chromium | (3.2, 3.1, 2.3) | (3.3, 3.3, 3.1) | | Cu, Copper | (0.1, 0.8, 1.1) | (3.5, 2.5, 2.4) | Index of refraction of selected metals as approximated RGB coefficients, based on data from https://refractiveindex.info/. The `roughness` parameter controls the variation of microfacets and thus how polished the metal will look. The roughness can be modified by a [texture](#texture) `map_roughness` ([texture transformations](#texture-transformations) are supported as well) to create notable edging effects.

### Alloy The [path tracer](#path-tracer) offers an alloy material, which behaves similar to [Metal](#metal), but allows for more intuitive and flexible control of the color. To create an Alloy material pass the type string “`alloy`†to `ospNewMaterial`. Its parameters are | Type | Name | Default | Description | |:------|:----------|----------:|:--------------------------------------------------------| | vec3f | color | white 0.9 | reflectivity at normal incidence (0 degree, linear RGB) | | vec3f | edgeColor | white | reflectivity at grazing angle (90 degree, linear RGB) | | float | roughness | 0.1 | roughness, in \[0–1\], 0 is perfect mirror | Parameters of the Alloy material. The main appearance of the Alloy material is controlled by the parameter `color`, while `edgeColor` influences the tint of reflections when seen at grazing angles (for real metals this is always 100% white). If present, the color component of [geometries](#geometries) is also used for reflectivity at normal incidence `color`. As in [Metal](#metal) the `roughness` parameter controls the variation of microfacets and thus how polished the alloy will look. All parameters can be textured by passing a [texture](#texture) handle, prefixed with “`map_`â€; [texture transformations](#texture-transformations) are supported as well.

### Glass The [path tracer](#path-tracer) offers a realistic a glass material, supporting refraction and volumetric attenuation (i.e., the transparency color varies with the geometric thickness). To create a Glass material pass the type string “`glass`†to `ospNewMaterial`. Its parameters are | Type | Name | Default | Description | |:------|:--------------------|--------:|:------------------------------------------------| | float | eta | 1.5 | index of refraction | | vec3f | attenuationColor | white | resulting color due to attenuation (linear RGB) | | float | attenuationDistance | 1 | distance affecting attenuation | Parameters of the Glass material. For convenience, the rather counter-intuitive physical attenuation coefficients will be calculated from the user inputs in such a way, that the `attenuationColor` will be the result when white light traveled through a glass of thickness `attenuationDistance`.

### ThinGlass The [path tracer](#path-tracer) offers a thin glass material useful for objects with just a single surface, most prominently windows. It models a thin, transparent slab, i.e., it behaves as if a second, virtual surface is parallel to the real geometric surface. The implementation accounts for multiple internal reflections between the interfaces (including attenuation), but neglects parallax effects due to its (virtual) thickness. To create a such a thin glass material pass the type string “`thinGlass`†to `ospNewMaterial`. Its parameters are | Type | Name | Default | Description | |:------|:--------------------|--------:|:------------------------------------------------| | float | eta | 1.5 | index of refraction | | vec3f | attenuationColor | white | resulting color due to attenuation (linear RGB) | | float | attenuationDistance | 1 | distance affecting attenuation | | float | thickness | 1 | virtual thickness | Parameters of the ThinGlass material. For convenience the attenuation is controlled the same way as with the [Glass](#glass) material. Additionally, the color due to attenuation can be modulated with a [texture](#texture) `map_attenuationColor` ([texture transformations](#texture-transformations) are supported as well). If present, the color component of [geometries](#geometries) is also used for the attenuation color. The `thickness` parameter sets the (virtual) thickness and allows for easy exchange of parameters with the (real) [Glass](#glass) material; internally just the ratio between `attenuationDistance` and `thickness` is used to calculate the resulting attenuation and thus the material appearance.

### MetallicPaint The [path tracer](#path-tracer) offers a metallic paint material, consisting of a base coat with optional flakes and a clear coat. To create a MetallicPaint material pass the type string “`metallicPaint`†to `ospNewMaterial`. Its parameters are listed in the table below. | Type | Name | Default | Description | |:------|:------------|----------:|:--------------------------------------| | vec3f | baseColor | white 0.8 | color of base coat (linear RGB) | | float | flakeAmount | 0.3 | amount of flakes, in \[0–1\] | | vec3f | flakeColor | Aluminium | color of metallic flakes (linear RGB) | | float | flakeSpread | 0.5 | spread of flakes, in \[0–1\] | | float | eta | 1.5 | index of refraction of clear coat | Parameters of the MetallicPaint material. The color of the base coat `baseColor` can be textured by a [texture](#texture) `map_baseColor`, which also supports [texture transformations](#texture-transformations). If present, the color component of [geometries](#geometries) is also used for the color of the base coat. Parameter `flakeAmount` controls the proportion of flakes in the base coat, so when setting it to 1 the `baseColor` will not be visible. The shininess of the metallic component is governed by `flakeSpread`, which controls the variation of the orientation of the flakes, similar to the `roughness` parameter of [Metal](#metal). Note that the effect of the metallic flakes is currently only computed on average, thus individual flakes are not visible.

### Luminous The [path tracer](#path-tracer) supports the Luminous material which emits light uniformly in all directions and which can thus be used to turn any geometric object into a light source. It is created by passing the type string “`luminous`†to `ospNewMaterial`. The amount of constant radiance that is emitted is determined by combining the general parameters of lights: [`color` and `intensity`](#lights) (which essentially means that parameter `intensityQuantity` is not needed because it is always `OSP_INTENSITY_QUANTITY_RADIANCE`). | Type | Name | Default | Description | |:------|:-------------|--------:|:----------------------------------------| | vec3f | color | white | color of the emitted light (linear RGB) | | float | intensity | 1 | intensity of the light (a factor) | | float | transparency | 0 | material transparency | Parameters accepted by the Luminous material. The emission can be textured by passing a `map_color` [texture](#texture) handle, [texture transformations](#texture-transformations) are supported as well.

Texture ------- OSPRay currently implements two texture types (`texture2d` and `volume`) and is open for extension to other types by applications. More types may be added in future releases. To create a new texture use ``` cpp OSPTexture ospNewTexture(const char *type); ``` ### Texture2D The `texture2d` texture type implements an image-based texture, where its parameters are as follows | Type | Name | Description | |:--------------|:---------|:------------------------------------------------------------------------------------| | uint | format | `OSPTextureFormat` for the texture | | uint | filter | default `OSP_TEXTURE_FILTER_LINEAR`, alternatively `OSP_TEXTURE_FILTER_NEAREST` | | OSPData | data | the actual texel 2D [data](#data) | | uint / vec2ui | wrapMode | `OSPTextureWrapMode` for the texture coordinates s and t; supported wrap modes are: | | | | `OSP_TEXTURE_WRAP_REPEAT` (default) | | | | `OSP_TEXTURE_WRAP_MIRRORED_REPEAT` | | | | `OSP_TEXTURE_WRAP_CLAMP_TO_EDGE` | Parameters of `texture2d` texture type. The supported texture formats for `texture2d` are: | Name | Description | |:--------------------|:---------------------------------------------------------------------------| | OSP_TEXTURE_RGBA8 | 8 bit \[0–255\] linear components red, green, blue, alpha | | OSP_TEXTURE_SRGBA | 8 bit sRGB gamma encoded color components, and linear alpha | | OSP_TEXTURE_RGBA32F | 32 bit float components red, green, blue, alpha | | OSP_TEXTURE_RGBA16F | 16 bit float components red, green, blue, alpha | | OSP_TEXTURE_RGB8 | 8 bit \[0–255\] linear components red, green, blue | | OSP_TEXTURE_SRGB | 8 bit sRGB gamma encoded components red, green, blue | | OSP_TEXTURE_RGB32F | 32 bit float components red, green, blue | | OSP_TEXTURE_RGB16F | 16 bit float components red, green, blue | | OSP_TEXTURE_R8 | 8 bit \[0–255\] linear single component red | | OSP_TEXTURE_RA8 | 8 bit \[0–255\] linear two components red, alpha | | OSP_TEXTURE_L8 | 8 bit \[0–255\] gamma encoded luminance (replicated into red, green, blue) | | OSP_TEXTURE_LA8 | 8 bit \[0–255\] gamma encoded luminance, and linear alpha | | OSP_TEXTURE_RA32F | 32 bit float two component red, alpha | | OSP_TEXTURE_R32F | 32 bit float single component red | | OSP_TEXTURE_RA16F | 16 bit float two component red, alpha | | OSP_TEXTURE_R16F | 16 bit float single component red | | OSP_TEXTURE_RGBA16 | 16 bit \[0–65535\] linear components red, green, blue, alpha | | OSP_TEXTURE_RGB16 | 16 bit \[0–65535\] linear components red, green, blue | | OSP_TEXTURE_RA16 | 16 bit \[0–65535\] linear two components red, alpha | | OSP_TEXTURE_R16 | 16 bit \[0–65535\] linear single component red | Supported texture formats by `texture2d`, i.e., valid constants of type `OSPTextureFormat`. The size of the texture is inferred from the size of the 2D array `data`, which also needs have a compatible type to `format`. The texel data in `data` starts with the texels in the lower left corner of the texture image, like in OpenGL. Per default a texture fetch is filtered by performing bi-linear interpolation of the nearest 2×2 texels; if instead fetching only the nearest texel is desired (i.e., no filtering) then pass the `OSP_TEXTURE_FILTER_NEAREST` flag. Texturing with `texture2d` image textures requires [geometries](#geometries) with texture coordinates, e.g., a [mesh](#mesh) with `vertex.texcoord` provided. ### Volume Texture The `volume` texture type implements texture lookups based on 3D object coordinates of the surface hit point on the associated geometry. If the given hit point is within the attached volume, the volume is sampled and classified with the transfer function attached to the volume. This implements the ability to visualize volume values (as colored by a transfer function) on arbitrary surfaces inside the volume (as opposed to an isosurface showing a particular value in the volume). Its parameters are as follows | Type | Name | Description | |:--------------------|:-----------------|:------------------------------------------------------------| | OSPVolume | volume | [Volume](#volumes) used to generate color lookups | | OSPTransferFunction | transferFunction | [transfer function](#transfer-function) applied to `volume` | Parameters of `volume` texture type. TextureVolume can be used for implementing slicing of volumes with any geometry type. It enables coloring of the slicing geometry with a different transfer function than that of the sliced volume. ### Texture Transformations All materials with textures also offer to manipulate the placement of these textures with the help of texture transformations. If so, this convention shall be used: the following parameters are prefixed with “`texture_name.*`â€). | Type | Name | Description | |:---------|:------------|:-------------------------------------------------| | linear2f | transform | linear transformation (rotation, scale) | | float | rotation | angle in degree, counterclockwise, around center | | vec2f | scale | enlarge texture, relative to center $(0.5, 0.5)$ | | vec2f | translation | move texture in positive direction (right/up) | Parameters to define 2D texture coordinate transformations. Above parameters are combined into a single `affine2d` transformation matrix and the transformations are applied in the given order. Rotation, scale and translation are interpreted “texture centricâ€, i.e., their effect seen by an user are relative to the texture (although the transformations are applied to the texture coordinates). | Type | Name | Description | |:---------|:----------|:---------------------------------------------------------| | affine3f | transform | linear transformation (rotation, scale) plus translation | Parameter to define 3D volume texture transformations. Similarly, volume texture placement can also be modified by an `affine3f` transformation matrix. Cameras ------- To create a new camera of given type `type` use ``` cpp OSPCamera ospNewCamera(const char *type); ``` All cameras accept these parameters: | Type | Name | Default | Description | |:-------------|:-----------------------|---------------------:|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------| | vec3f | position | $(0, 0, 0)$ | position of the camera | | vec3f | direction | $(0, 0, 1)$ | main viewing direction of the camera | | vec3f | up | $(0, 1, 0)$ | up direction of the camera | | affine3f | transform | identity | additional world-space transform, overridden by `motion.*` arrays | | float | nearClip | 10-6 | near clipping distance | | vec2f | imageStart | $(0, 0)$ | start of image region (lower left corner) | | vec2f | imageEnd | $(1, 1)$ | end of image region (upper right corner) | | affine3f\[\] | motion.transform | | additional uniformly distributed world-space transforms | | vec3f\[\] | motion.scale | | additional uniformly distributed world-space scale, overridden by `motion.transform` | | vec3f\[\] | motion.pivot | | additional uniformly distributed world-space translation which is applied before `motion.rotation` (i.e., the rotation center), overridden by `motion.transform` | | quatf\[\] | motion.rotation | | additional uniformly distributed world-space quaternion rotation, overridden by `motion.transform` | | vec3f\[\] | motion.translation | | additional uniformly distributed world-space translation, overridden by `motion.transform` | | box1f | time | \[0, 1\] | time associated with first and last key in `motion.*` arrays | | box1f | shutter | \[0.5, 0.5\] | start and end of shutter time (for motion blur), in \[0, 1\] | | uint | shutterType | `OSP_SHUTTER_GLOBAL` | `OSPShutterType` for motion blur, also allowed are: | | | | | `OSP_SHUTTER_ROLLING_RIGHT` | | | | | `OSP_SHUTTER_ROLLING_LEFT` | | | | | `OSP_SHUTTER_ROLLING_DOWN` | | | | | `OSP_SHUTTER_ROLLING_UP` | | float | rollingShutterDuration | 0 | for a rolling shutter (see `shutterType`) the “open†time per line, in \[0, `shutter`.upper-`shutter`.lower\] | Parameters accepted by all cameras. The camera is placed and oriented in the world with `position`, `direction` and `up`. Additionally, an extra transformation `transform` can be specified, which will only be applied to 3D vectors (i.e., `position`, `direction` and `up`), but does *not* affect any sizes (e.g., `nearClip`, `apertureRadius`, or `height`). The same holds for the array of transformations `motion.transform` to achieve camera motion blur (in combination with `time` and `shutter`). OSPRay uses a right-handed coordinate system. The region of the camera sensor that is rendered to the image can be specified in normalized screen-space coordinates with `imageStart` (lower left corner) and `imageEnd` (upper right corner). This can be used, for example, to crop the image, to achieve asymmetrical view frusta, or to horizontally flip the image to view scenes which are specified in a left-handed coordinate system. Note that values outside the default range of \[0–1\] are valid, which is useful to easily realize overscan or film gate, or to emulate a shifted sensor. ### Perspective Camera The perspective camera implements a simple thin lens camera for perspective rendering, supporting optionally depth of field and stereo rendering (with the [path tracer](#path-tracer)). It is created by passing the type string “`perspective`†to `ospNewCamera`. In addition to the [general parameters](#cameras) understood by all cameras the perspective camera supports the special parameters listed in the table below. | Type | Name | Default | Description | |:------|:-----------------------|------------------:|:-----------------------------------------------------------------------| | float | fovy | 60 | the field of view (angle in degree) of the frame’s height | | float | aspect | 1 | ratio of width by height of the frame (and image region) | | float | apertureRadius | 0 | size of the aperture, controls the depth of field | | float | focusDistance | 1 | distance at where the image is sharpest when depth of field is enabled | | bool | architectural | false | vertical edges are projected to be parallel | | uint | stereoMode | `OSP_STEREO_NONE` | `OSPStereoMode` for stereo rendering, also allowed are: | | | | | `OSP_STEREO_LEFT` | | | | | `OSP_STEREO_RIGHT` | | | | | `OSP_STEREO_SIDE_BY_SIDE` | | | | | `OSP_STEREO_TOP_BOTTOM` (left eye at top half) | | float | interpupillaryDistance | 0.0635 | distance between left and right eye when stereo is enabled | Additional parameters accepted by the perspective camera. Note that when computing the `aspect` ratio a potentially set image region (using `imageStart` & `imageEnd`) needs to be regarded as well. In architectural photography it is often desired for aesthetic reasons to display the vertical edges of buildings or walls vertically in the image as well, regardless of how the camera is tilted. Enabling the `architectural` mode achieves this by internally leveling the camera parallel to the ground (based on the `up` direction) and then shifting the lens such that the objects in direction `dir` are centered in the image. If finer control of the lens shift is needed use `imageStart` & `imageEnd`. Because the camera is now effectively leveled its image plane and thus the plane of focus is oriented parallel to the front of buildings, the whole façade appears sharp, as can be seen in the example images below. The resolution of the [framebuffer](#framebuffer) is not altered by `imageStart`/`imageEnd`.
Example image created with the perspective camera, featuring depth of field.
Enabling the architectural flag corrects the perspective projection distortion, resulting in parallel vertical edges.
Example 3D stereo image using stereoMode = OSP_STEREO_SIDE_BY_SIDE.
### Orthographic Camera The orthographic camera implements a simple camera with orthographic projection, without support for depth. It is created by passing the type string “`orthographic`†to `ospNewCamera`. In addition to the [general parameters](#cameras) understood by all cameras the orthographic camera supports the following special parameters: | Type | Name | Description | |:------|:-------|:------------------------------------------------------------| | float | height | size of the camera’s image plane in y, in world coordinates | | float | aspect | ratio of width by height of the frame | Additional parameters accepted by the orthographic camera. For convenience the size of the camera sensor, and thus the extent of the scene that is captured in the image, can be controlled with the `height` parameter. The same effect can be achieved with `imageStart` and `imageEnd`, and both methods can be combined. In any case, the `aspect` ratio needs to be set accordingly to get an undistorted image.
Example image created with the orthographic camera.
### Panoramic Camera The panoramic camera implements a simple camera with support for stereo rendering. It captures the complete surrounding with a latitude / longitude mapping and thus the rendered images should best have a ratio of 2:1. A panoramic camera is created by passing the type string “`panoramic`†to `ospNewCamera`. It is placed and oriented in the scene by using the [general parameters](#cameras) understood by all cameras. | Type | Name | Description | |:------|:-----------------------|:---------------------------------------------------------------------------| | uint | stereoMode | `OSPStereoMode` for stereo rendering, possible values are: | | | | `OSP_STEREO_NONE` (default) | | | | `OSP_STEREO_LEFT` | | | | `OSP_STEREO_RIGHT` | | | | `OSP_STEREO_SIDE_BY_SIDE` | | | | `OSP_STEREO_TOP_BOTTOM` (left eye at top half) | | float | interpupillaryDistance | distance between left and right eye when stereo is enabled, default 0.0635 | Additional parameters accepted by the panoramic camera.
Latitude / longitude map created with the panoramic camera.
Scene Hierarchy --------------- ### Groups Groups in OSPRay represent collections of GeometricModels, VolumetricModels and Lights which share a common local-space coordinate system. To create a group call ``` cpp OSPGroup ospNewGroup(); ``` Groups take arrays of geometric models, volumetric models, clipping geometric models and lights, but they are all optional. In other words, there is no need to create empty arrays if there are no geometries, volumes or lights in the group. By adding `OSPGeometricModel`s to the `clippingGeometry` array a clipping geometry feature is enabled. Geometries assigned to this parameter will be used as clipping geometries. Any supported geometry can be used for clipping[^6], the only requirement is that it has to distinctly partition space into clipping and non-clipping one. The use of clipping geometry that is not closed or infinite could result in rendering artifacts. User can decide which part of space is clipped by changing shading normals orientation with the `invertNormals` flag of the [GeometricModel](#geometricmodels). All geometries and volumes assigned to `geometry` or `volume` will be clipped. All clipping geometries from all groups and [Instances](#instances) will be combined together – a union of these areas will be applied to all other objects in the [world](#world). | Type | Name | Default | Description | |:-----------------------|:-----------------|--------:|:-------------------------------------------------------------------------------------------------------------------------------------| | OSPGeometricModel\[\] | geometry | NULL | [data](#data) array of [GeometricModels](#geometricmodels) | | OSPVolumetricModel\[\] | volume | NULL | [data](#data) array of [VolumetricModels](#volumetricmodels) | | OSPGeometricModel\[\] | clippingGeometry | NULL | [data](#data) array of [GeometricModels](#geometricmodels) used for clipping | | OSPLight\[\] | light | NULL | [data](#data) array of [lights](#lights) | | bool | dynamicScene | false | tell Embree to use faster BVH build (slower ray traversal), otherwise optimized for faster ray traversal (slightly slower BVH build) | | bool | compactMode | false | tell Embree to use a more compact BVH in memory by trading ray traversal performance | | bool | robustMode | false | tell Embree to enable more robust ray intersection code paths (slightly slower) | Parameters understood by groups. ### Instances Instances in OSPRay represent a single group’s placement into the world via a transform. To create and instance call ``` cpp OSPInstance ospNewInstance(OSPGroup); ``` The passed group can be `NULL` as long as the group to be instanced is passed as a parameter. If both a group is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the group object passed on object creation is again used. | Type | Name | Default | Description | |:-------------|:-------------------|---------:|:------------------------------------------------------------------------------------------------------------------------------------------------------| | OSPGroup | group | | optional [group](#groups) object to be instanced | | affine3f | transform | identity | world-space transform for all attached geometries and volumes, overridden by `motion.*` arrays | | affine3f\[\] | motion.transform | | uniformly distributed world-space transforms | | vec3f\[\] | motion.scale | | uniformly distributed world-space scale, overridden by `motion.transform` | | vec3f\[\] | motion.pivot | | uniformly distributed world-space translation which is applied before `motion.rotation` (i.e., the rotation center), overridden by `motion.transform` | | quatf\[\] | motion.rotation | | uniformly distributed world-space quaternion rotation, overridden by `motion.transform` | | vec3f\[\] | motion.translation | | uniformly distributed world-space translation, overridden by `motion.transform` | | box1f | time | \[0, 1\] | time associated with first and last key in `motion.*` arrays (for motion blur) | | uint32 | id | -1u | optional user ID, for [framebuffer](#framebuffer) channel `OSP_FB_ID_INSTANCE` | Parameters understood by instances. ### World Worlds are a container of scene data represented by [instances](#instances). To create an (empty) world call ``` cpp OSPWorld ospNewWorld(); ``` Objects are placed in the world through an array of instances. Similar to [groups](#groups), the array of instances is optional: there is no need to create empty arrays if there are no instances (though there will be nothing to render). Applications can query the world (axis-aligned) bounding box after the world has been committed. To get this information, call ``` cpp OSPBounds ospGetBounds(OSPObject); ``` The result is returned in the provided `OSPBounds`[^7] struct: ``` cpp typedef struct { float lower[3]; float upper[3]; } OSPBounds; ``` This call can also take `OSPGroup` and `OSPInstance` as well: all other object types will return an empty bounding box. Finally, Worlds can be configured with parameters for making various feature/performance trade-offs (similar to groups). | Type | Name | Default | Description | |:----------------|:-------------|--------:|:-------------------------------------------------------------------------------------------------------------------------------------| | OSPInstance\[\] | instance | NULL | [data](#data) array with handles of the [instances](#instances) | | OSPLight\[\] | light | NULL | [data](#data) array with handles of the [lights](#lights) | | bool | dynamicScene | false | tell Embree to use faster BVH build (slower ray traversal), otherwise optimized for faster ray traversal (slightly slower BVH build) | | bool | compactMode | false | tell Embree to use a more compact BVH in memory by trading ray traversal performance | | bool | robustMode | false | tell Embree to enable more robust ray intersection code paths (slightly slower) | Parameters understood by worlds. Renderers --------- A renderer is the central object for rendering in OSPRay. Different renderers implement different features and support different materials. To create a new renderer of given type `type` use ``` cpp OSPRenderer ospNewRenderer(const char *type); ``` General parameters of all renderers are | Type | Name | Default | Description | |:----------------------|:------------------|------------------------:|:--------------------------------------------------------------------------------------------------------------------------------------------| | int | pixelSamples | 1 | samples per pixel, best results when a power of 2 | | int | maxPathLength | 20 | maximum ray recursion depth | | float | minContribution | 0.001 | sample contributions below this value will be neglected to speedup rendering | | float | varianceThreshold | 0 | threshold for adaptive accumulation | | float / vec3f / vec4f | backgroundColor | black, transparent | background color and alpha (linear A/RGB/RGBA), if no `map_backplate` is set | | OSPTexture | map_backplate | | optional [texture](#texture) image used as background (use texture type `texture2d`) | | OSPTexture | map_maxDepth | | optional screen-sized float [texture](#texture) with maximum far distance per pixel (use texture type `texture2d`) | | OSPMaterial\[\] | material | | optional [data](#data) array of [materials](#materials) which can be indexed by a [GeometricModel](#geometricmodels)’s `material` parameter | | uint | pixelFilter | `OSP_PIXELFILTER_GAUSS` | `OSPPixelFilterType` to select the pixel filter used by the renderer for antialiasing. Possible pixel filters are listed below. | | float | mipMapBias | 0 | bias for texture MIP-mapping, balancing between sharpness/aliasing and blurriness due to prefiltering | Parameters understood by all renderers. OSPRay’s renderers support a feature called adaptive accumulation, which accelerates progressive [rendering](#rendering) by stopping the rendering and refinement of image regions that have an estimated variance below the `varianceThreshold`. This feature requires a [framebuffer](#framebuffer) with an `OSP_FB_VARIANCE` channel. Per default the background of the rendered image will be transparent black, i.e., the alpha channel holds the opacity of the rendered objects. This eases transparency-aware blending of the image with an arbitrary background image by the application (via $ospray.rgb + appBackground.rgb⋅(1-ospray.alpha)$). The parameter `backgroundColor` or `map_backplate` can be used to already blend with a constant background color or backplate texture, respectively, (and alpha) during rendering. OSPRay renderers support depth composition with images of other renderers, for example to incorporate help geometries of a 3D UI that were rendered with OpenGL. The screen-sized [texture](#texture) `map_maxDepth` must have format `OSP_TEXTURE_R32F` and flag `OSP_TEXTURE_FILTER_NEAREST`. The fetched values are used to limit the distance of primary rays, thus objects of other renderers can hide objects rendered by OSPRay. OSPRay supports antialiasing in image space by using pixel filters, which are aligned around the center of a pixel. The size $w×w$ of the filter depends on the selected filter type. The types of supported pixel filters are defined by the `OSPPixelFilterType` enum and can be set using the `pixelFilter` parameter. | Name | Description | |:--------------------------------|:--------------------------------------------------------------------------------------------------------------| | OSP_PIXELFILTER_POINT | a point filter only samples the center of the pixel, therefore the filter width is $w = 0$ | | OSP_PIXELFILTER_BOX | a uniform box filter with a width of $w = 1$ | | OSP_PIXELFILTER_GAUSS | a truncated, smooth Gaussian filter with a standard deviation of $\sigma = 0.5$ and a filter width of $w = 3$ | | OSP_PIXELFILTER_MITCHELL | the Mitchell-Netravali filter with a width of $w = 4$ | | OSP_PIXELFILTER_BLACKMAN_HARRIS | the Blackman-Harris filter with a width of $w = 3$ | Pixel filter types supported by OSPRay for antialiasing in image space. OSPRay also antialiases textures with prefiltering and MIP-mapping, which can be adjusted with parameter `mipMapBias`. For final frame rendering with a high number of `pixelSamples` or accumulated frames `mipMapBias` can be lowered (e.g., set to -0.5 or -2) to result in sharper textures which are essentially anisotropically filtered. Conversely, for preview rendering with just a single sample per pixel a higher `mipMapBias` of 1 or 2 can reduce texture aliasing and increase rendering speed. ### SciVis Renderer The SciVis renderer is a fast ray tracer for scientific visualization which supports volume rendering and ambient occlusion (AO). It is created by passing the type string “`scivis`†to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers, the SciVis renderer supports the following parameters: | Type | Name | Default | Description | |:------|:-------------------|----------------:|:------------------------------------------------------------------------------------------------------------------------| | bool | shadows | false | whether to compute (hard) shadows | | int | aoSamples | 0 | number of rays per sample to compute ambient occlusion | | float | aoDistance | 1020 | maximum distance to consider for ambient occlusion | | float | volumeSamplingRate | 1 | sampling rate for volumes | | bool | visibleLights | false | whether light sources are potentially visible (as in the [path tracer](#path-tracer), regarding each light’s `visible`) | Special parameters understood by the SciVis renderer. Note that the intensity (and color) of AO is deduced from an [ambient light](#ambient-light) in the `lights` array.[^8] If `aoSamples` is zero (the default) then ambient lights cause ambient illumination (without occlusion). ### Ambient Occlusion Renderer This renderer supports only a subset of the features of the [SciVis renderer](#scivis-renderer) to gain performance. As the name suggest its main shading method is ambient occlusion (AO), [lights](#lights) are *not* considered at all. Volume rendering is supported. The Ambient Occlusion renderer is created by passing the type string “`ao`†to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers the following parameters are supported as well: | Type | Name | Default | Description | |:------|:-------------------|----------------:|:-------------------------------------------------------| | int | aoSamples | 1 | number of rays per sample to compute ambient occlusion | | float | aoDistance | 1020 | maximum distance to consider for ambient occlusion | | float | aoIntensity | 1 | ambient occlusion strength | | float | volumeSamplingRate | 1 | sampling rate for volumes | Special parameters understood by the Ambient Occlusion renderer. ### Path Tracer The path tracer supports soft shadows, indirect illumination and realistic materials. This renderer is created by passing the type string “`pathtracer`†to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers the path tracer supports the following special parameters: | Type | Name | Default | Description | |:------|:--------------------------|--------:|:------------------------------------------------------------------------------------------------------------------------------------------| | int | lightSamples | all | number of random light samples per path vertex, best results when a power of 2; per default all light sources are sampled | | bool | limitIndirectLightSamples | true | after the first non-specular (i.e., diffuse and glossy) path vertex take (at most) a single light sample (instead of `lightSamples` many) | | int | roulettePathLength | 5 | ray recursion depth at which to start Russian roulette termination | | int | maxScatteringEvents | 20 | maximum number of non-specular (i.e., diffuse and glossy) bounces | | float | maxContribution | ∞ | samples are clamped to this value before they are accumulated into the framebuffer | | bool | backgroundRefraction | false | allow for alpha blending even if background is seen through refractive objects like glass | Special parameters understood by the path tracer. The path tracer requires that [materials](#materials) are assigned to [geometries](#geometries), otherwise surfaces are treated as completely black. The path tracer supports [volumes](#volumes) with multiple scattering. The scattering albedo can be specified using the [transfer function](#transfer-function). Extinction is assumed to be spectrally constant. Framebuffer ----------- The framebuffer holds the rendered 2D image (and optionally auxiliary information associated with pixels). To create a new framebuffer object of given size `size` (in pixels), color format, and channels use ``` cpp OSPFrameBuffer ospNewFrameBuffer(int size_x, int size_y, OSPFrameBufferFormat format = OSP_FB_SRGBA, uint32_t frameBufferChannels = OSP_FB_COLOR); ``` The parameter `format` describes the format the color buffer has *on the host*, and the format that `ospMapFrameBuffer` will eventually return. Valid values are: | Name | Description | |:---------------|:------------------------------------------------------------| | OSP_FB_NONE | framebuffer will not be mapped by the application | | OSP_FB_RGBA8 | 8 bit \[0–255\] linear component red, green, blue, alpha | | OSP_FB_SRGBA | 8 bit sRGB gamma encoded color components, and linear alpha | | OSP_FB_RGBA32F | 32 bit float components red, green, blue, alpha | Supported color formats of the framebuffer that can be passed to `ospNewFrameBuffer`, i.e., valid constants of type `OSPFrameBufferFormat`. The parameter `frameBufferChannels` specifies which channels the framebuffer holds, and can be combined together by bitwise OR from the values of `OSPFrameBufferChannel` listed in the table below. | Name | Description | |:--------------------|:-------------------------------------------------------------------------------------------------------------------------------------------| | OSP_FB_COLOR | RGB color including alpha | | OSP_FB_DEPTH | euclidean distance to the camera (*not* to the image plane), as linear 32 bit float; for multiple samples per pixel their minimum is taken | | OSP_FB_ACCUM | accumulation buffer for progressive refinement | | OSP_FB_VARIANCE | for estimation of the current noise level if OSP_FB_ACCUM is also present, see [rendering](#rendering) | | OSP_FB_NORMAL | accumulated world-space normal of the first non-specular hit, as vec3f | | OSP_FB_ALBEDO | accumulated material albedo (color without illumination) at the first non-specular hit, as vec3f | | OSP_FB_ID_PRIMITIVE | primitive index of the first hit, as uint32 | | OSP_FB_ID_OBJECT | geometric/volumetric model `id`, if specified, or index in [group](#groups) of first hit, as uint32 | | OSP_FB_ID_INSTANCE | user defined [instance](#instances) `id`, if specified, or instance index of first hit, as uint32 | Framebuffer channels constants (of type `OSPFrameBufferChannel`), naming optional information the framebuffer can store. These values can be combined by bitwise OR when passed to `ospNewFrameBuffer`. If a certain channel value is *not* specified, the given buffer channel will not be present. Note that OSPRay makes a clear distinction between the *external* format of the framebuffer and the internal one: The external format is the format the user specifies in the `format` parameter; it specifies what color format OSPRay will eventually *return* the framebuffer to the application (when calling `ospMapFrameBuffer`): no matter what OSPRay uses internally, it will simply return a 2D array of pixels of that format, with possibly all kinds of reformatting, compression/decompression, etc., going on in-between the generation of the *internal* framebuffer and the mapping of the externally visible one. In particular, `OSP_FB_NONE` is a perfectly valid pixel format for a framebuffer that an application will never map. For example, an application driving a display wall may well generate an intermediate framebuffer and eventually transfer its pixel to the individual displays using an `OSPImageOperation` [image operation](#image-operation). The application can map the given channel of a framebuffer – and thus access the stored pixel information – via ``` cpp const void *ospMapFrameBuffer(OSPFrameBuffer, OSPFrameBufferChannel = OSP_FB_COLOR); ``` Note that `OSP_FB_ACCUM` or `OSP_FB_VARIANCE` cannot be mapped. The origin of the screen coordinate system in OSPRay is the lower left corner (as in OpenGL), thus the first pixel addressed by the returned pointer is the lower left pixel of the image. A previously mapped channel of a framebuffer can be unmapped by passing the received pointer `mapped` to ``` cpp void ospUnmapFrameBuffer(const void *mapped, OSPFrameBuffer); ``` The individual channels of a framebuffer can be cleared with ``` cpp void ospResetAccumulation(OSPFrameBuffer); ``` This function will clear *all* accumulating buffers (`OSP_FB_VARIANCE`, `OSP_FB_NORMAL`, and `OSP_FB_ALBEDO`, if present) and resets the accumulation counter `accumID`. It is unspecified if the existing color and depth buffers are physically cleared when `ospResetAccumulation` is called. If `OSP_FB_VARIANCE` is specified, an estimate of the variance of the last accumulated frame can be queried with ``` cpp float ospGetVariance(OSPFrameBuffer); ``` Note this value is only updated after synchronizing with `OSP_FRAME_FINISHED`, as further described in [asynchronous rendering](#asynchronous-rendering). The estimated variance can be used by the application as a quality indicator and thus to decide whether to stop or to continue progressive rendering. The framebuffer takes a list of pixel operations to be applied to the image in sequence as an `OSPData`. The pixel operations will be run in the order they are in the array. | Type | Name | Description | |:----------------------|:---------------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | OSPImageOperation\[\] | imageOperation | ordered sequence of image operations | | int | targetFrames | anticipated number of frames that will be accumulated for progressive refinement, used renderers to generate a blue noise sampling pattern; should be a power of 2, is always 1 without `OSP_FB_ACCUM`; default 0 (disabled) | Parameters accepted by the framebuffer. If the total number of frames to be accumulated is known, then `targetFrames` should be set, because then renderers can generate more pleasing blue noise patterns. Accumulation stops when `targetFrames` is reached. ### Image Operation Image operations are functions that are applied to every pixel of a frame. Examples include post-processing, filtering, blending, tone mapping, or sending tiles to a display wall. To create a new pixel operation of given type `type` use ``` cpp OSPImageOperation ospNewImageOperation(const char *type); ``` #### Tone Mapper The tone mapper is a pixel operation which implements a generic filmic tone mapping operator. Using the default parameters it approximates the Academy Color Encoding System (ACES). The tone mapper is created by passing the type string “`tonemapper`†to `ospNewImageOperation`. The tone mapping curve can be customized using the parameters listed in the table below. | Type | Name | Default | Filmic | Description | |:------|:----------|--------:|-------:|:-------------------------------------------------------------------------| | float | exposure | 1.0 | 1.0 | amount of light per unit area | | float | contrast | 1.6773 | 1.1759 | contrast (toe of the curve); typically is in \[1–2\] | | float | shoulder | 0.9714 | 0.9746 | highlight compression (shoulder of the curve); typically is in \[0.9–1\] | | float | midIn | 0.18 | 0.18 | mid-level anchor input; default is 18% gray | | float | midOut | 0.18 | 0.18 | mid-level anchor output; default is 18% gray | | float | hdrMax | 11.0785 | 6.3704 | maximum HDR input that is not clipped | | bool | acesColor | true | false | apply the ACES color transforms | Parameters accepted by the tone mapper. The column “Filmic†lists alternative values for the popular “Uncharted 2†tone mapping curve (note that that curve includes an exposure bias to match 18% middle gray). #### Denoiser OSPRay comes with a module that adds support for Intel® Open Image Denoise (OIDN). This is provided as an optional module as it creates an additional project dependency at compile time. The module implements a “`denoiser`†frame operation, which denoises the entire frame before the frame is completed. OIDN will automatically select the fastest device, using a GPU when available. The device selection be overridden by the environment variable `OIDN_DEFAULT_DEVICE`, possible values are `cpu`, `sycl`, `cuda`, `hip`, or a physical device ID | Type | Name | Description | |:-----|:-------------|:-------------------------------------------------------------------------------------------------------------------| | uint | quality | `OSPDenoiserQuality` for denoiser quality, default is | | | | `OSP_DENOISER_QUALITY_MEDIUM`: balanced quality/performance for interactive/real-time rendering; also allowed are: | | | | `OSP_DENOISER_QUALITY_LOW`: high performance, for interactive/real-time preview rendering | | | | `OSP_DENOISER_QUALITY_HIGH`: high quality, for final frame rendering | | bool | denoiseAlpha | whether to denoise the alpha channel as well, default false | Parameters accepted by the denoiser. Rendering --------- ### Asynchronous Rendering Rendering is by default asynchronous (non-blocking), and is done by combining a framebuffer, renderer, camera, and world. What to render and how to render it depends on the renderer’s parameters. If the framebuffer supports accumulation (i.e., it was created with `OSP_FB_ACCUM`) then successive calls to `ospRenderFrame` will progressively refine the rendered image (until `targetFrames` is reached). To start an render task, use ``` cpp OSPFuture ospRenderFrame(OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld); ``` This returns an `OSPFuture` handle, which can be used to synchronize with the application, cancel, or query for progress of the running task. When `ospRenderFrame` is called, there is no guarantee when the associated task will begin execution. Progress of a running frame can be queried with the following API function ``` cpp float ospGetProgress(OSPFuture); ``` This returns the approximated progress of the task in \[0-1\]. Applications can cancel a currently running asynchronous operation via ``` cpp void ospCancel(OSPFuture); ``` Applications can wait on the result of an asynchronous operation, or choose to only synchronize with a specific event. To synchronize with an `OSPFuture` use ``` cpp void ospWait(OSPFuture, OSPSyncEvent = OSP_TASK_FINISHED); ``` The following are values which can be synchronized with the application | Name | Description | |:--------------------|:------------------------------------------------------------------------------------------------------------------------------------------------| | OSP_NONE_FINISHED | Do not wait for anything to be finished (immediately return from `ospWait`) | | OSP_WORLD_COMMITTED | Wait for the world to be committed (not yet implemented) | | OSP_WORLD_RENDERED | Wait for the world to be rendered, but not post-processing operations (Pixel/Tile/Frame Op) | | OSP_FRAME_FINISHED | Wait for all rendering operations to complete | | OSP_TASK_FINISHED | Wait on full completion of the task associated with the future. The underlying task may involve one or more of the above synchronization events | Supported events that can be passed to `ospWait`. Currently only rendering can be invoked asynchronously. However, future releases of OSPRay may add more asynchronous versions of API calls (and thus return `OSPFuture`). Applications can query whether particular events are complete with ``` cpp int ospIsReady(OSPFuture, OSPSyncEvent = OSP_TASK_FINISHED); ``` As the given running task runs (as tracked by the `OSPFuture`), applications can query a boolean \[0, 1\] result if the passed event has been completed. Applications can query how long an async task ran with ``` cpp float ospGetTaskDuration(OSPFuture); ``` This returns the wall clock execution time of the task in seconds. If the task is still running, this will block until the task is completed. This is useful for applications to query exactly how long an asynchronous task executed without the overhead of measuring both task execution + synchronization by the calling application. ### Synchronous Rendering For convenience in certain use cases, `ospray_util.h` provides a synchronous version of `ospRenderFrame`: ``` cpp float ospRenderFrameBlocking(OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld); ``` This version is the equivalent of: ``` cpp ospRenderFrame ospWait(f, OSP_TASK_FINISHED) return ospGetVariance(fb) ``` This version is closest to `ospRenderFrame` from OSPRay v1.x. ### Rendering and ospCommit The use of either `ospRenderFrame` or `ospRenderFrameBlocking` requires that all objects in the scene being rendered have been committed before rendering occurs. If a call to `ospCommit` happens while a frame is rendered, the result is undefined behavior and should be avoided. ### Picking To get the world-space position of the geometry (if any) seen at \[0–1\] normalized screen-space pixel coordinates `screenPos_x` and `screenPos_y` use ``` cpp void ospPick(OSPPickResult *, OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld, float screenPos_x, float screenPos_y); ``` The result is returned in the provided `OSPPickResult` struct: ``` cpp typedef struct { int hasHit; float worldPosition[3]; OSPInstance instance; OSPGeometricModel model; uint32_t primID; } OSPPickResult; ``` Note that `ospPick` considers exactly the same camera of the given renderer that is used to render an image, thus matching results can be expected. If the camera supports depth of field then the center of the lens and thus the center of the circle of confusion is used for picking. Note that the caller needs to `ospRelease` the `instance` and `model` handles of `OSPPickResult` once the information is not needed anymore. Modules and Devices =================== CPU --- The CPU module is implicitly loaded and the `cpu` device is automatically used if no other options are specified. GPU (Beta) ---------- To use the GPU for rendering load the `gpu` module and select the `gpu` device: ``` sh ./ospExamples --osp:load-modules=gpu --osp:device=gpu ``` or via explicit device creation by the application: ``` cpp ospLoadModule("gpu"); OSPDevice dev = ospNewDevice("gpu"); ospDeviceCommit(dev); ospSetCurrentDevice(dev); ``` | Type | Name | Description | |:--------|:------------|:-------------| | void \* | syclContext | SYCL context | | void \* | syclDevice | SYCL device | Parameters specific to the `gpu` device. Applications can set their SYCL context and device to share device memory with OSPRay or to control which device should be used (e.g., in case multiple GPUs are present). If neither parameter is set, the `gpu` device will automatically create a context internally and select a GPU (that selection can be influenced via environment variable `ONEAPI_DEVICE_SELECTOR`, see [Intel oneAPI DPC++ Compiler documentation](https://intel.github.io/llvm-docs/EnvironmentVariables.html#oneapi-device-selector)). Compile times for just in time compilation (JIT compilation) can be large. To resolve this issue we recommend enabling persistent JIT compilation caching inside your application before the SYCL device is created, by setting environment variables `SYCL_CACHE_PERSISTENT=1` (and optionally `SYCL_CACHE_DIR=` to some proper directory where the JIT cache should get stored). To reduce GPU memory allocation overhead when rendering scenes with many objects (geometries, instances, etc.), memory pooling should be enabled by setting the environment variable `SYCL_PI_LEVEL_ZERO_USM_ALLOCATOR="1;0;shared:1M,0,2M"`. See [Intel oneAPI DPC++ Compiler documentation](https://intel.github.io/llvm-docs/EnvironmentVariables.html#debugging-variables-for-level-zero-plugin) for more details. ### Known Issues The following features are not implemented yet or are not working correctly on the GPU device: - Multiple volumes in the scene - Clipping - Motion blur - Subdivision surfaces - Progress reporting via `ospGetProgress` or canceling the frame via `ospCancel` - Picking via `ospPick` - Adaptive accumulation via `OSP_FB_VARIANCE` and `varianceThreshold` - Framebuffer channels `OSP_FB_ID_*` (id buffers) - Experimental support for shared device-only data, works only for `structuredRegular` volume There will be some delay on start-up as the kernel code is JIT compiled for the device, and similar pauses when changing the scene configuration, because the kernel specialized and re-compiled. For some combination of compiler, GPU driver and scene the rendered images might show artifacts (e.g., vertical lines or small blocks). Distributed Rendering with MPI ------------------------------ The purpose of OSPRay’s MPI modules is to provide distributed rendering capabilities for OSPRay. The modules enables image- and data-parallel rendering across HPC clusters using MPI, allowing applications to transparently distribute rendering work, or to render data sets which are too large to fit in memory on a single machine. OSPRay provides multiple MPI modules that expose different distributed rendering capabilities. The `mpi_offload` module provides image-parallel rendering through the `mpiOffload` device; it enables OSPRay applications written for local rendering to be replicated across multiple nodes to distribute the rendering work without code changes. And the `mpi_distributed_cpu` and `mpi_distributed_gpu` modules provides data-parallel rendering through the `mpiDistributed` device, which allows MPI distributed applications to use OSPRay for distributed rendering. Each rank using the `mpiDistributed` device can render an independent piece of a global data set, or perform hybrid rendering where ranks partially or completely share data. The `mpiDistributed` device’s image-parallel rendering support can be used to accelerate data loading for image-parallel applications, where all ranks load the same data from a shared disk and then perform image-parallel rendering on the replicated data, as if the `mpiOffload` device where being used. ### MPI Offload Rendering The `mpiOffload` device can be used to distribute image rendering tasks across a cluster without requiring modifications to the application itself. Existing applications using OSPRay for local rendering simply be passed command line arguments to load the module and indicate that the `mpiOffload` device should be used for image-parallel rendering. To load the module, pass `--osp:load-modules=mpi_offload`, to select the MPIOffloadDevice, pass `--osp:device=mpiOffload`. For example, the `ospExamples` application can be run as: ``` sh mpirun -n ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload ``` and will automatically distribute the image rendering tasks among the corresponding `N` nodes. Note that in this configuration rank 0 will act as a master/application rank, and will run the user application code but not perform rendering locally. Thus, a minimum of 2 ranks are required, one master to run the application and one worker to perform the rendering. Running with 3 ranks for example would now distribute half the image rendering work to rank 1 and half to rank 2. If more control is required over the placement of ranks to nodes, or you want to run a worker rank on the master node as well you can run the application and the `ospray_mpi_worker` program through MPI’s MPMD mode. The `ospray_mpi_worker` will load the MPI module and select the offload device by default. ``` sh mpirun -n 1 ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload \ : -n ./ospray_mpi_worker ``` If initializing the `mpiOffload` device manually, or passing parameters through the command line, the following parameters can be set: | Type | Name | Default | Description | |:-------|:------------------------|--------:|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | string | mpiMode | mpi | The mode to communicate with the worker ranks. `mpi` will assume you are launching the application and workers in the same mpi command (or split launch command). `mpi` is the only supported mode | | uint | maxCommandBufferEntries | 8192 | Set the max number of commands to buffer before submitting the command buffer to the workers | | uint | commandBufferSize | 512 MiB | Set the max command buffer size to allow. Units are in MiB. Max size is 1.8 GiB | | uint | maxInlineDataSize | 32 MiB | Set the max size of an OSPData which can be inline’d into the command buffer instead of being sent separately. Max size is half the commandBufferSize. Units are in MiB | Parameters specific to the `mpiOffload` device. The `maxCommandBufferEntries`, `commandBufferSize`, and `maxInlineDataSize` can also be set via the environment variables: `OSPRAY_MPI_MAX_COMMAND_BUFFER_ENTRIES`, `OSPRAY_MPI_COMMAND_BUFFER_SIZE`, and `OSPRAY_MPI_MAX_INLINE_DATA_SIZE`, respectively. The `mpiOffload` device uses a dynamic load balancer by default. If you wish to use a static load balancer you can do so by setting the `OSPRAY_STATIC_BALANCER` environment variable to 1. For the worker ranks to create GPU devices instead of the default CPU devices set the environment variable `OSPRAY_MPI_DISTRIBUTED_GPU`, e.g., ``` sh export OSPRAY_MPI_DISTRIBUTED_GPU=1 ``` or ``` sh mpiexec -genv OSPRAY_MPI_DISTRIBUTED_GPU 1 \ -n 1 ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload \ : -n 2 ./ospray_mpi_worker ``` The `mpiOffload` device does not support multiple init/shutdown cycles. Thus, to run `ospBenchmark` for this device make sure to exclude the init/shutdown test by passing `--benchmark_filter=-ospInit_ospShutdown` through the command line. ### MPI Distributed Rendering While MPI Offload rendering is used to transparently distribute rendering work without requiring modification to the application, MPI Distributed rendering is targeted at use of OSPRay within MPI-parallel applications. The MPI distributed device can be selected by loading the `mpi_distributed_cpu` module for CPU rendering or `mpi_distributed_gpu` for GPU rendering, and manually creating and using an instance of the `mpiDistributed` device, for example: ``` cpp ospLoadModule("mpi_distributed_cpu"); OSPDevice mpiDevice = ospNewDevice("mpiDistributed"); ospDeviceCommit(mpiDevice); ospSetCurrentDevice(mpiDevice); ``` Your application can either initialize MPI before-hand, ensuring that `MPI_THREAD_SERIALIZED` or higher is supported, or allow the device to initialize MPI on commit. Thread multiple support is required if your application will make MPI calls while rendering asynchronously with OSPRay. When using the distributed device each rank can specify independent local data using the OSPRay API, as if rendering locally. However, when calling `ospRenderFrameAsync` the ranks will work collectively to render the data. The distributed device supports both image-parallel, where the data is replicated, and data-parallel, where the data is distributed, rendering modes. The `mpiDistributed` device will by default use each rank in `MPI_COMM_WORLD` as a render worker; however, it can also take a specific MPI communicator to use as the world communicator. Only those ranks in the specified communicator will participate in rendering. | Type | Name | Default | Description | |:--------|:------------------|---------------:|:--------------------------------------------------------------------------| | void \* | worldCommunicator | MPI_COMM_WORLD | The MPI communicator which the OSPRay workers should treat as their world | Parameters specific to the `mpiDistributed` device. | Type | Name | Default | Description | |:----------|:-------|--------:|:-------------------------------------------------------------------------------------| | box3f\[\] | region | NULL | A list of bounding boxes which bound the owned local data to be rendered by the rank | Parameters specific to the distributed `OSPWorld`. | Type | Name | Default | Description | |:------|:-------------------|----------------:|:-------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | int | aoSamples | 0 | The number of AO samples to take per-pixel | | float | aoDistance | 1020 | The AO ray length to use. Note that if the AO ray would have crossed a rank boundary and ghost geometry is not available, there will be visible artifacts in the shading | | float | volumeSamplingRate | 1 | sampling rate for volumes | Parameters specific to the `mpiRaycast` renderer. #### Image Parallel Rendering in the MPI Distributed Device If all ranks specify exactly the same data, the distributed device can be used for image-parallel rendering. This works identical to the offload device, except that the MPI-aware application is able to load data in parallel on each rank rather than loading on the master and shipping data out to the workers. When a parallel file system is available, this can improve data load times. Image-parallel rendering is selected by specifying the same data on each rank, and using any of the existing local renderers (e.g., `scivis`, `pathtracer`). See [ospMPIDistribTutorialReplicated](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialReplicated.cpp) for an example. #### Data Parallel Rendering in the MPI Distributed Device The MPI Distributed device also supports data-parallel rendering with sort-last compositing. Each rank can specify a different piece of data, as long as the bounding boxes of each rank’s data are non-overlapping. The rest of the scene setup is similar to local rendering; however, for distributed rendering only the `mpiRaycast` renderer is supported. This renderer implements a subset of the `scivis` rendering features which are suitable for implementation in a distributed environment. By default the aggregate bounding box of the instances in the local world will be used as the bounds of that rank’s data. However, when using ghost zones for volume interpolation, geometry or ambient occlusion, each rank’s data can overlap. To clip these non-owned overlap regions out a set of regions (the `region` parameter) can pass as a parameter to the `OSPWorld` being rendered. Each rank can specify one or more non-overlapping `box3f`’s which bound the portions of its local data which it is responsible for rendering. See the [ospMPIDistribTutorialVolume](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialVolume.cpp) for an example. Finally, the MPI distributed device also supports hybrid-parallel rendering, where multiple ranks can share a single piece of data. For each shared piece of data the rendering work will be assigned image-parallel among the ranks. Partially-shared regions are determined by finding those ranks specifying data with the same bounds (matching regions) and merging them. See the [ospMPIDistribTutorialPartialRepl](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialPartialRepl.cpp) for an example. #### Picking on Distributed Data in the MPI Distributed Device Calling `ospPick` in the distributed device will find and return the closest global object at the screen position on the rank that owns that object. The other ranks will report no hit. Picking in the distributed device takes into account data clipping applied through the `regions` parameter to avoid picking ghost data. ### Interaction with User Modules The MPI Offload rendering mode trivially supports user modules, with the caveat that attempting to share data directly with the application (e.g., passing a `void *` or other tricks to the module) will not work in a distributed environment. Instead, use the `ospNewSharedData` API to share data from the application with OSPRay, which will in turn be copied over the network to the workers. The MPI Distributed device also supports user modules, as all that is required for compositing the distributed data are the bounds of each rank’s local data. MultiDevice ----------- The multidevice module is an experimental OSPRay device type that renders images by delegating off pixel tiles to a number of internal delegate OSPRay devices. If you wish to try it set the `OSPRAY_NUM_SUBDEVICES` environmental variable to the number of subdevices you want to create and tell OSPRay to both load the `multidevice_cpu` extension and create a multidevice for rendering instead of the default CPU device. One example in a bash like shell is as follows: ``` sh OSPRAY_NUM_SUBDEVICES=6 ./ospTutorial --osp:load-modules=multidevice_cpu --osp:device=multidevice ``` Note that the multidevice currently does not support `OSPImageOperation`s for denoising nor tone mapping. Tutorials ========= ospTutorial ----------- A minimal working example demonstrating how to use OSPRay can be found at [`apps/tutorials/ospTutorial.c`](https://github.com/ospray/ospray/blob/master/apps/ospTutorial/ospTutorial.c)[^9]. An example of building `ospTutorial.c` with CMake can be found in [`apps/tutorials/ospTutorialFindospray/`](https://github.com/ospray/ospray/tree/master/apps/ospTutorial/ospTutorialFindospray). To build the tutorial on Linux, build it in a build directory with ``` sh gcc -std=c99 ../apps/ospTutorial/ospTutorial.c \ -I ../ospray/include -L . -lospray -Wl,-rpath,. -o ospTutorial ``` On Windows build it can be build manually in a “build_directory\\\$Configuration†directory with ``` sh cl ..\..\apps\ospTutorial\ospTutorial.c -I ..\..\ospray\include -I ..\.. ospray.lib ``` Running `ospTutorial` will create two images of two triangles, rendered with the Scientific Visualization renderer with full Ambient Occlusion. The first image `firstFrame.ppm` shows the result after one call to `ospRenderFrame` – jagged edges and noise in the shadow can be seen. Calling `ospRenderFrame` multiple times enables progressive refinement, resulting in antialiased edges and converged shadows, shown after ten frames in the second image `accumulatedFrames.ppm`. ![First frame.](https://ospray.github.io/images/tutorial_firstframe.png) ![After accumulating ten frames.](https://ospray.github.io/images/tutorial_accumulatedframe.png) ospExamples ----------- Apart from tutorials, `OSPRay` comes with a C++ app called [`ospExamples`](https://github.com/ospray/ospray/tree/master/apps/ospExamples) which is an elaborate easy-to-use tutorial, with a single interface to try various `OSPRay` features. It is aimed at providing users with multiple simple scenes composed of basic geometry types, lights, volumes etc. to get started with OSPRay quickly. `ospExamples` app runs a `GLFWOSPRayWindow` instance that manages instances of the camera, framebuffer, renderer and other OSPRay objects necessary to render an interactive scene. The scene is rendered on a `GLFW` window with an `imgui` GUI controls panel for the user to manipulate the scene at runtime. The application is located in [`apps/ospExamples/`](https://github.com/ospray/ospray/tree/master/apps/ospExamples) directory and can be built with CMake. It can be run from the build directory via: ./ospExamples The command line parameter is optional however.

### Scenes Different scenes can be selected from the `scenes` dropdown and each scene corresponds to an instance of a special `detail::Builder` struct. Example builders are located in [`apps/common/ospray_testing/builders/`](https://github.com/ospray/ospray/tree/master/apps/common/ospray_testing/builders). These builders provide a usage guide for the OSPRay scene hierarchy and OSPRay API in the form of `cpp` wrappers. They instantiate and manage objects for the specific scene like `cpp::Geometry`, `cpp::Volume`, `cpp::Light` etc. The `detail::Builder` base struct is mostly responsible for setting up OSPRay `world` and objects common in all scenes (for example lighting and ground plane), which can be conveniently overridden in the derived builders. ### Renderer This app comes with four [renderer](#renderers) options: `scivis`, `pathtracer`, `ao` and `debug`. The app provides some common rendering controls like `pixelSamples` and other more specific to the renderer type like `aoSamples` for the `scivis` and `ao` renderer or `maxPathLength` for the `pathtracer`. The sun-sky lighting can be used in a sample scene by enabling the `renderSunSky` option of the `pathtracer` renderer. It allows the user to change `turbidity` and `sunDirection`.

ospMPIDistribTutorial --------------------- A minimal working example demonstrating how to use OSPRay for rendering distributed data can be found at [`modules/mpi/tutorials/ospMPIDistribTutorial.c`](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorial.c)[^10]. The compilation process via CMake is the similar to [`apps/tutorials/ospTutorialFindospray/`](https://github.com/ospray/ospray/tree/master/apps/ospTutorial/ospTutorialFindospray), with the addition of finding and linking MPI. To build the tutorial on Linux, build it in a build directory with ``` sh mpicc -std=c99 ../modules/mpi/tutorials/ospMPIDistribTutorial.c \ -I ../ospray/include -L . -lospray -Wl,-rpath,. -o ospMPIDistribTutorial ``` On Windows build it can be build manually in a “build_directory\\\$Configuration†directory with ``` sh cl ..\..\modules\mpi\tutorials\ospMPIDistribTutorial.c -I ..\..\ospray\include -I ..\.. ospray.lib ``` The MPI module does not need to be linked explicitly, as it is loaded as a module at runtime.

ospMPIDistribTutorialSpheres and ospMPIDistribTutorialVolume ------------------------------------------------------------ The spheres and volume distributed tutorials are built as part of the MPI tutorials when building OSPRay with the MPI module and tutorials enabled. These tutorials demonstrate using OSPRay to render distributed data sets where each rank owns some subregion of the data, and displaying the output in an interactive window. The domain is distributed in a grid among the processes, each of which will generate a subset of the data corresponding to its subdomain. In `ospMPIDistribTutorialSpheres`, each process generates a set of spheres within its assigned domain. The spheres are colored from dark to light blue, where lighter colors correspond to higher ranks.

In `ospMPIDistribTutorialVolume`, each process generates a subbrick of volume data, which is colored by its rank.

ospMPIDistribTutorialPartialRepl -------------------------------- The partially replicated MPI tutorial demonstrates how to use OSPRay’s distributed rendering capabilities to render data sets that are partially replicated among the processes. Each pair of ranks generates the same volume brick, allowing them to subdivide the rendering workload between themselves. For example, when run with two ranks, each will generate the same brick and be responsible for rendering half of the image tiles it projects to. When run with four ranks, the pairs of ranks 0,1 and 2,3 will generate the same data and divide the rendering workload for that data among themselves. The image work subdivision happens automatically, based on which ranks specify the same bounding box for their data, as demonstrated in the tutorial. The partially replicated distribution is useful to support load-balanced rendering of data sets that are too large to be fully replicated among the processes, but are small enough to be partially replicated among them. ospMPIDistribTutorialReplicated ------------------------------- The replicated MPI tutorial demonstrates how OSPRay’s distributed rendering capabilities can be used to render data sets that are fully replicated among the ranks with advanced illumination effects. In this case, although the processes are run MPI parallel, each rank specifies the exact same data. OSPRay’s MPI parallel renderer will detect that the data is replicated in this case and use the same image-parallel rendering algorithms employed in the MPI offload rendering configuration to render the data. This image-parallel rendering algorithm supports all rendering configurations that are used in local rendering, e.g., path tracing, to provide high-quality images. The replicated MPI tutorial supports the same scenes and parameters as the [`ospExamples`](#ospexamples) app described above. This mode can be useful when high-quality rendering is desired and it is possible to copy the entire data set on to each rank, or to accelerate loading of a large model by leveraging a parallel file system.

Reporting a Vulnerability ------------------------- Please [report any security vulnerabilities][guidelines] in this project utilizing the [guidelines here][guidelines]. [guidelines]: https://www.intel.com/content/www/us/en/security-center/vulnerability-handling-guidelines.html "Vulnerability Handling Guidelines" RenderKit-ospray-85af292/STYLEGUIDE.md000066400000000000000000000160001464752671100172700ustar00rootroot00000000000000OSPRay Style Guide ================== This document discusses the project's expectations on C++ and ISPC style. In general, the items discussed are meant to be a guide and not be overly strict. However, deviations from this document should be supported with technical reasoning. This document is relatively simple and meant as a "quick overview" of expectations for OSPRay. A more complete set of guidelines for all of C++ can be found in the [ISO C++ Core Guidelines](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md). Documentation ------------- In general, comments in code should describe "why" not "what". Code documentation should be in terms of C++ style single-line comments or multi-line C style comments. Avoid Doxygen-style code documentation, this is deprecated. When adding or updating public API definitions, update the corresponding `doc/api.md` documentation as part of your merge request. This keeps our documentation always current, and minimizes the need for audits at release time. Markdown files (`.md`) should use a 72 column limit for running text, exceptions are URLs or example code (i.e. preformatted sections in backticks). General Code Goals ------------------ In all code, the overall goal is to make interfaces "easy to use correctly" and "difficult to use incorrectly". Some characteristics that make code better are: - Keep reasoning as local as possible - Descriptive names - Short functions - Single functions/abstractions for repetitive concepts (less copy/paste) - Compile errors over runtime errors We have a number of small, single-purpose abstractions in `rkcommon` that aide in the above goals. It is expected for contributions to first try and use those constructs before implementing their own. Lastly, it is expected that code is formatted using the provided `.clang-format` config found in the root of the repository, e.g. by running `git-clang-format` (which also avoids changes which are only due to formatting). Consider to pre-format very long strings using C++11 raw string literals. NOTE: Both C++ and ISPC files can be formatted with clang-format. Naming conventions for public API --------------------------------- - Prefer enums over string parameters. - Parameter and object names are camelCase (e.g. `metallicPaint`) - Parameter names are singular, even if it is an array (e.g. `index`, `material`) - Data belonging together like the members of an array of structs, which are passed as struct of arrays, have a common prefix. For example `vertex.color` and `vertex.normals` - Switches (bools) name just what they switch, e.g. `shadows` (not `shadowsEnabled` nor `enableShadows`, nor `useShadows`) C++ Usage Guidelines -------------------- C++ is a big language, so the following are things that we prefer to see in OSPRay: ### Memory Management, Object Lifetimes, and Pointers - For collections, prefer STL containers over C arrays, specifically `std::vector` and `rkcommon::containers::AlignedVector`. - Prefer smart pointers to manage memory over raw `new` and `delete`. - Prefer the usage of `std::unique_ptr` to manage heap objects, until memory lifetimes must be managed by more than one observer. - Prefer constructing smart pointers with `rkcommon::make_unique<>` and `std::make_shared<>` over using `new`. - Avoid globals and `std::shared_ptr` that cross translation units. - Prefer global scope variables to be marked `static`. - Prefer functions to access global data in another translation unit over marking them as `extern`. - Keep raw pointer usage local, either in a function or in a single cpp file. - Prefer the usage of references over pointers for cases where `nullptr` is not a valid value. - Prefer using `rkcommon::utility::OnScopeExit` to robustly cleanup non-trivial objects in a function. - Avoid constructing `static` data that requires initialization ordering with other `static` data. ### Designing Types (classes/structs) - Define empty default constructors with `= default;`, not with an empty `{}`. - Use the `virtual` keyword only to mark that child classes are expected to override, not that the function is overriding a parent method. - Always use the `override` keyword where appropriate. - Prefer to write `const` functions by default. - Prefer implementing inline member functions below the definition of the class or struct. This makes classes easier to read by avoiding unnecessary implementation details when reading the class interface. - Implement `begin()` and `end()` iterators for types which abstract collections. - Consider whether the type should be move-only (ex: `std::unique_ptr`) or copyable. - Prefer `= delete;` syntax to delete constructors over marking them `private`. - Prefer giving all applicable member values inlined default values. - Only populate values in constructor initialization if the value is different than the default or is being set by a constructor parameter. - Only mark methods as `virtual` if the class is intended to be in an inheritance hierarchy. - Always implement a `virtual` destructor, even if it's `= default;`. ### Loops, STL Algorithms, and Threading - Prefer the usage of an algorithm call over implementing a raw loop. - Prefer making multi-STL algorithm functions their own function with a name. - Prefer using `rkcommon::tasking` constructs instead of raw threads. - Prefer range-based for loops over indexing for loops where possible. - Avoid shared mutable state in parallel code (requires synchronization). - Capture type preference for lambda functions should be `[]` → `[&]` → `[=]`. ### Templates - Prefer to constrain template types to only relevant types using `static_assert()` and type traits. - Use `std::forward` when passing universal references (`T&&`) to other templates. - Only use SFINAE when necessary, and try to keep its usage as simple as possible. ISPC Usage ---------- The following are concerns specific to ISPC: - Prefer using `uniform` variables. The point of ISPC is to have varying data, but uniform values are more efficient than replicated varying values. - Avoid writing unnecessary `uniform` and `varying` keywords. Examples: ``` {.cpp} varying float f; // 'varying' is redundant, variables are varying by default uniform float *p; // 'uniform' is redundant, pointers point to uniform by default ``` - Prefer omitting `uniform`/`varying` qualifiers for structs. Only apply them if they need to be consistently the same for both `uniform` and `varying` instances of the struct. ### OSPRay ISPCDevice Specific Design Choices - Prefer to use Embree C API bindings over ISPC where possible. - Prefer to throw exceptions when an object is found to be invalid during `commit()`. - Prefer setting ISPC-side values in a single `set()` call over many single value setting functions. - Minimize the number of alias names given to both object types and parameters.

Initialization and Shutdown --------------------------- To use the API, OSPRay must be initialized with a "device". A device is the object which implements the API. Creating and initializing a device can be done in either of two ways: command line arguments using `ospInit` or manually instantiating a device and setting parameters on it. ### Command Line Arguments The first is to do so by giving OSPRay the command line from `main()` by calling OSPError ospInit(int *argc, const char **argv); OSPRay parses (and removes) its known command line parameters from your application's `main` function. For an example see the [tutorial]. For possible error codes see section [Error Handling and Status Messages]. It is important to note that the arguments passed to `ospInit` are processed in order they are listed. The following parameters (which are prefixed by convention with "`--osp:`") are understood: -------------------------------------------- ----------------------------------------------------- Parameter Description -------------------------------------------- ----------------------------------------------------- `--osp:debug` enables various extra checks and debug output, and disables multi-threading `--osp:num-threads=` use `n` threads instead of per default using all detected hardware threads `--osp:log-level=` set logging level; valid values (in order of severity) are `none`, `error`, `warning`, `info`, and `debug` `--osp:warn-as-error` send `warning` and `error` messages through the error callback, otherwise send `warning` messages through the message callback; must have sufficient `logLevel` to enable warnings `--osp:verbose` shortcut for `--osp:log-level=info` and enable debug output on `cout`, error output on `cerr` `--osp:vv` shortcut for `--osp:log-level=debug` and enable debug output on `cout`, error output on `cerr` `--osp:load-modules=[,...]` load one or more modules during initialization; equivalent to calling `ospLoadModule(name)` `--osp:log-output=` convenience for setting where status messages go; valid values for `dst` are `cerr` and `cout` `--osp:error-output=` convenience for setting where error messages go; valid values for `dst` are `cerr` and `cout` `--osp:device=` use `name` as the type of device for OSPRay to create; e.g., `--osp:device=cpu` gives you the default `cpu` device; Note if the device to be used is defined in a module, remember to pass `--osp:load-modules=` first `--osp:set-affinity=` if `1`, bind software threads to hardware threads; `0` disables binding; default is `0` `--osp:device-params=:[,...]` set one or more other device parameters; equivalent to calling `ospDeviceSet*(param, value)` -------------------------------------------- ----------------------------------------------------- : Command line parameters accepted by OSPRay's `ospInit`. ### Manual Device Instantiation The second method of initialization is to explicitly create the device and possibly set parameters. This method looks almost identical to how other [objects] are created and used by OSPRay (described in later sections). The first step is to create the device with OSPDevice ospNewDevice(const char *type); where the `type` string maps to a specific device implementation. OSPRay always provides the "`cpu`" device, which maps to a fast, local CPU implementation. Other devices can also be added through additional modules, such as distributed MPI device implementations. See next Chapter for details. Once a device is created, you can call void ospDeviceSetParam(OSPObject, const char *id, OSPDataType type, const void *mem); to set parameters on the device. The semantics of setting parameters is exactly the same as `ospSetParam`, which is documented below in the [parameters] section. The following parameters can be set on all devices: ------ ------------------------ ---------------------------------------------- Type Name Description ------ ------------------------ ---------------------------------------------- int numThreads number of threads which OSPRay should use bool disableMipMapGeneration disable the default generation of MIP maps for textures (e.g., to save the additional memory needed) uint logLevel logging level; valid values (in order of severity) are `OSP_LOG_NONE`, `OSP_LOG_ERROR`, `OSP_LOG_WARNING`, `OSP_LOG_INFO`, and `OSP_LOG_DEBUG` string logOutput convenience for setting where status messages go; valid values are `cerr` and `cout` string errorOutput convenience for setting where error messages go; valid values are `cerr` and `cout` bool debug set debug mode; equivalent to `logLevel=debug` and `numThreads=1` bool warnAsError send `warning` and `error` messages through the error callback, otherwise send `warning` messages through the message callback; must have sufficient `logLevel` to enable warnings bool setAffinity bind software threads to hardware threads if set to 1; 0 disables binding omitting the parameter will let OSPRay choose ------ ------------------------ ---------------------------------------------- : Parameters shared by all devices. Once parameters are set on the created device, the device must be committed with void ospDeviceCommit(OSPDevice); To use the newly committed device, you must call void ospSetCurrentDevice(OSPDevice); This then sets the given device as the object which will respond to all other OSPRay API calls. Device handle lifetimes are managed with two calls, the first which increments the internal reference count to the given `OSPDevice` void ospDeviceRetain(OSPDevice) and the second which decrements the reference count void ospDeviceRelease(OSPDevice) Users can change parameters on the device after initialization (from either method above), by calling OSPDevice ospGetCurrentDevice(); This function returns the handle to the device currently used to respond to OSPRay API calls, where users can set/change parameters and recommit the device. If changes are made to the device that is already set as the current device, it does not need to be set as current again. Note this API call will increment the ref count of the returned device handle, so applications must use `ospDeviceRelease` when finished using the handle to avoid leaking the underlying device object. If there is no current device set, this will return an invalid `NULL` handle. When a device is created, its reference count is initially `1`. When a device is set as the current device, it internally has its reference count incremented. Note that `ospDeviceRetain` and `ospDeviceRelease` should only be used with reference counts that the application tracks: removing reference held by the current set device should be handled by `ospShutdown`. Thus, `ospDeviceRelease` should only decrement the reference counts that come from `ospNewDevice`, `ospGetCurrentDevice`, and the number of explicit calls to `ospDeviceRetain`. OSPRay allows applications to query runtime properties of a device in order to do enhanced validation of what device was loaded at runtime. The following function can be used to get these device-specific properties (attributes about the device, not parameter values) int64_t ospDeviceGetProperty(OSPDevice, OSPDeviceProperty); It returns an integer value of the queried property and the following properties can be provided as parameter: OSP_DEVICE_VERSION OSP_DEVICE_VERSION_MAJOR OSP_DEVICE_VERSION_MINOR OSP_DEVICE_VERSION_PATCH OSP_DEVICE_SO_VERSION ### Environment Variables OSPRay's generic device parameters can be overridden via environment variables for easy changes to OSPRay's behavior without needing to change the application (variables are prefixed by convention with "`OSPRAY_`"): --------------------- -------------------------------------------------------- Variable Description --------------------- -------------------------------------------------------- OSPRAY_NUM_THREADS equivalent to `--osp:num-threads` OSPRAY_LOG_LEVEL equivalent to `--osp:log-level` OSPRAY_LOG_OUTPUT equivalent to `--osp:log-output` OSPRAY_ERROR_OUTPUT equivalent to `--osp:error-output` OSPRAY_DEBUG equivalent to `--osp:debug` OSPRAY_WARN_AS_ERROR equivalent to `--osp:warn-as-error` OSPRAY_SET_AFFINITY equivalent to `--osp:set-affinity` OSPRAY_LOAD_MODULES equivalent to `--osp:load-modules`, can be a comma separated list of modules which will be loaded in order OSPRAY_DEVICE equivalent to `--osp:device:` --------------------- -------------------------------------------------------- : Environment variables interpreted by OSPRay. Note that these environment variables take precedence over values specified through `ospInit` or manually set device parameters. ### Error Handling and Status Messages The following errors are currently used by OSPRay: Name Description ---------------------- ------------------------------------------------------- OSP_NO_ERROR no error occurred OSP_UNKNOWN_ERROR an unknown error occurred OSP_INVALID_ARGUMENT an invalid argument was specified OSP_INVALID_OPERATION the operation is not allowed for the specified object OSP_OUT_OF_MEMORY there is not enough memory to execute the command OSP_UNSUPPORTED_CPU the CPU is not supported (minimum ISA is SSE4.1 on x86_64 and NEON on ARM64) OSP_VERSION_MISMATCH a module could not be loaded due to mismatching version ---------------------- ------------------------------------------------------- : Possible error codes, i.e., valid named constants of type `OSPError`. These error codes are either directly return by some API functions, or are recorded to be later queried by the application via OSPError ospDeviceGetLastErrorCode(OSPDevice); A more descriptive error message can be queried by calling const char* ospDeviceGetLastErrorMsg(OSPDevice); Alternatively, the application can also register a callback function of type typedef void (*OSPErrorCallback)(void *userData, OSPError, const char* errorDetails); via void ospDeviceSetErrorCallback(OSPDevice, OSPErrorCallback, void *userData); to get notified when errors occur. Applications may be interested in messages which OSPRay emits, whether for debugging or logging events. Applications can call void ospDeviceSetStatusCallback(OSPDevice, OSPStatusCallback, void *userData); in order to register a callback function of type typedef void (*OSPStatusCallback)(void *userData, const char* messageText); which OSPRay will use to emit status messages. By default, OSPRay uses a callback which does nothing, so any output desired by an application will require that a callback is provided. Note that callbacks for C++ `std::cout` and `std::cerr` can be alternatively set through `ospInit` or the `OSPRAY_LOG_OUTPUT` environment variable. Applications can clear either callback by passing `NULL` instead of an actual function pointer. ### Loading OSPRay Extensions at Runtime OSPRay's functionality can be extended via plugins (which we call "modules"), which are implemented in shared libraries. To load module `name` from `libospray_module_.so` (on Linux and Mac OS\ X) or `ospray_module_.dll` (on Windows) use OSPError ospLoadModule(const char *name); Modules are searched in OS-dependent paths. `ospLoadModule` returns `OSP_NO_ERROR` if the plugin could be successfully loaded. ### Shutting Down OSPRay When the application is finished using OSPRay (typically on application exit), the OSPRay API should be finalized with void ospShutdown(); This API call ensures that the current device is cleaned up appropriately. Due to static object allocation having non-deterministic ordering, it is recommended that applications call `ospShutdown` before the calling application process terminates. Objects ------- All entities of OSPRay (the [renderer], [volumes], [geometries], [lights], [cameras], ...) are a logical specialization of `OSPObject` and share common mechanism to deal with parameters and lifetime. An important aspect of object parameters is that parameters do not get passed to objects immediately. Instead, parameters are not visible at all to objects until they get explicitly committed to a given object via a call to void ospCommit(OSPObject); at which time all previously additions or changes to parameters are visible at the same time. If a user wants to change the state of an existing object (e.g., to change the origin of an already existing camera) it is perfectly valid to do so, as long as the changed parameters are recommitted. The commit semantic allow for batching up multiple small changes, and specifies exactly when changes to objects will occur. This can impact performance and consistency for devices crossing a PCI bus or across a network. Note that OSPRay uses reference counting to manage the lifetime of all objects, so one cannot explicitly "delete" any object. Instead, to indicate that the application does not need and does not access the given object anymore, call void ospRelease(OSPObject); This decreases its reference count and if the count reaches `0` the object will automatically get deleted. Passing `NULL` is not an error. Note that every handle returned via the API needs to be released when the object is no longer needed, to avoid memory leaks. Sometimes applications may want to have more than one reference to an object, where it is desirable for the application to increment the reference count of an object. This is done with void ospRetain(OSPObject); It is important to note that this is only necessary if the application wants to call `ospRelease` on an object more than once: objects which contain other objects as parameters internally increment/decrement ref counts and should not be explicitly done by the application. ### Parameters Parameters allow to configure the behavior of and to pass data to objects. However, objects do _not_ have an explicit interface for reasons of high flexibility and a more stable compile-time API. Instead, parameters are passed separately to objects in an arbitrary order, and unknown parameters will simply be ignored (though a warning message will be posted). The following function allows adding various types of parameters with name `id` to a given object: void ospSetParam(OSPObject, const char *id, OSPDataType type, const void *mem); The valid parameter names for all `OSPObject`s and what types are valid are discussed in future sections. Note that `mem` must always be a pointer _to_ the object, otherwise accidental type casting can occur. This is especially true for pointer types (`OSP_VOID_PTR` and `OSPObject` handles), as they will implicitly cast to `void\ *`, but be incorrectly interpreted. To help with some of these issues, there also exist variants of `ospSetParam` for specific types, such as `ospSetInt` and `ospSetVec3f` in the OSPRay utility library (found in `ospray_util.h`). Note that half precision float parameters `OSP_HALF, OSP_VEC[234]H` are not supported. Users can also remove parameters that have been explicitly set from `ospSetParam`. Any parameters which have been removed will go back to their default value during the next commit unless a new parameter was set after the parameter was removed. To remove a parameter, use void ospRemoveParam(OSPObject, const char *id); ### Data OSPRay consumes data arrays from the application using a specific object type, `OSPData`. There are several components to describing a data array: element type, 1/2/3 dimensional striding, and whether the array is shared with the application or copied into opaque, OSPRay-owned memory. Shared data arrays require that the application's array memory outlives the lifetime of the created `OSPData`, as OSPRay is referring to application memory. Where this is not preferable, applications use opaque arrays to allow the `OSPData` to own the lifetime of the array memory. However, opaque arrays dictate the cost of copying data into it, which should be kept in mind. Thus, the most efficient way to specify a data array from the application is to created a shared data array, which is done with OSPData ospNewSharedData(const void *sharedData, OSPDataType, uint64_t numItems1, int64_t byteStride1 = 0, uint64_t numItems2 = 1, int64_t byteStride2 = 0, uint64_t numItems3 = 1, int64_t byteStride3 = 0, OSPDeleterCallback = NULL, void *userData = NULL); The call returns an `OSPData` handle to the created array. The calling program guarantees that the `sharedData` pointer will remain valid for the duration that this data array is being used. The number of elements `numItems` must be positive (there cannot be an empty data object). The data is arranged in three dimensions, with specializations to two or one dimension (if some `numItems` are 1). The distance between consecutive elements (per dimension) is given in bytes with `byteStride` and can also be negative. If `byteStride` is zero it will be determined automatically (e.g., as `sizeof(type)`). Strides do not need to be ordered, i.e., `byteStride2` can be smaller than `byteStride1`, which is equivalent to a transpose. However, if the stride should be calculated, then an ordering in dimensions is assumed to disambiguate, i.e., `byteStride1 < byteStride2 < byteStride3`. An application can pass ownership of shared data to OSPRay (for example, when it temporarily created a modified version of its data only to make it compatible with OSPRay) by providing a deleter function that OSPRay will call whenever the time comes to deallocate the shared buffer. The deleter function has the following signature: typedef void (*OSPDeleterCallback)(const void *userData, const void *sharedData); where `sharedData` will receive the address of the buffer and `userData` will receive whatever additional state the function needs to perform the deletion (both provided to `ospNewSharedData` when sharing the data with OSPRay). The enum type `OSPDataType` describes the different element types that can be represented in OSPRay; valid constants are listed in the table below. -------------------------- --------------------------------------------------- Type / Name Description -------------------------- --------------------------------------------------- OSP_DEVICE API device object reference OSP_DATA data reference OSP_OBJECT generic object reference OSP_CAMERA camera object reference OSP_FRAMEBUFFER framebuffer object reference OSP_FUTURE future object reference OSP_LIGHT light object reference OSP_MATERIAL material object reference OSP_TEXTURE texture object reference OSP_RENDERER renderer object reference OSP_WORLD world object reference OSP_GROUP group object reference OSP_INSTANCE instance object reference OSP_GEOMETRY geometry object reference OSP_GEOMETRIC_MODEL geometric model object reference OSP_VOLUME volume object reference OSP_VOLUMETRIC_MODEL volumetric model object reference OSP_TRANSFER_FUNCTION transfer function object reference OSP_IMAGE_OPERATION image operation object reference OSP_STRING C-style zero-terminated character string OSP_BOOL 8\ bit boolean OSP_CHAR, OSP_VEC[234]C 8\ bit signed character scalar and [234]-element vector OSP_UCHAR, OSP_VEC[234]UC 8\ bit unsigned character scalar and [234]-element vector OSP_SHORT, OSP_VEC[234]S 16\ bit unsigned integer scalar and [234]-element vector OSP_USHORT, OSP_VEC[234]US 16\ bit unsigned integer scalar and [234]-element vector OSP_INT, OSP_VEC[234]I 32\ bit signed integer scalar and [234]-element vector OSP_UINT, OSP_VEC[234]UI 32\ bit unsigned integer scalar and [234]-element vector OSP_LONG, OSP_VEC[234]L 64\ bit signed integer scalar and [234]-element vector OSP_ULONG, OSP_VEC[234]UL 64\ bit unsigned integer scalar and [234]-element vector OSP_HALF, OSP_VEC[234]H 16\ bit half precision floating-point scalar and [234]-element vector (IEEE 754 `binary16`) OSP_FLOAT, OSP_VEC[234]F 32\ bit single precision floating-point scalar and [234]-element vector OSP_DOUBLE, OSP_VEC[234]D 64\ bit double precision floating-point scalar and [234]-element vector OSP_BOX[1234]I 32\ bit integer box (lower + upper bounds) OSP_BOX[1234]F 32\ bit single precision floating-point box (lower + upper bounds) OSP_LINEAR[23]F 32\ bit single precision floating-point linear transform ([23] vectors) OSP_AFFINE[23]F 32\ bit single precision floating-point affine transform (linear transform plus translation) OSP_QUATF 32\ bit single precision floating-point quaternion, in $(i, j, k, w)$ layout OSP_VOID_PTR raw memory address (only found in module extensions) -------------------------- --------------------------------------------------- : Valid named constants for `OSPDataType`. If the elements of the array are handles to objects, then their reference counter is incremented. An opaque `OSPData` with memory allocated by OSPRay is created with OSPData ospNewData(OSPDataType, uint64_t numItems1, uint64_t numItems2 = 1, uint64_t numItems3 = 1); To allow for (partial) copies or updates of data arrays use void ospCopyData(const OSPData source, OSPData destination, uint64_t destinationIndex1 = 0, uint64_t destinationIndex2 = 0, uint64_t destinationIndex3 = 0); which will copy the whole^[The number of items to be copied is defined by the size of the source array.] content of the `source` array into `destination` at the given location `destinationIndex`. The `OSPDataType`s of the data objects must match. The region to be copied must be valid inside the destination, i.e., in all dimensions, `destinationIndex + sourceSize <= destinationSize`. The affected region `[destinationIndex, destinationIndex + sourceSize)` is marked as dirty, which may be used by OSPRay to only process or update that sub-region (e.g., updating an acceleration structure). If the destination array is shared with OSPData by the application (created with `ospNewSharedData`), then - the source array must be shared as well (thus `ospCopyData` cannot be used to read opaque data) - if source and destination memory overlaps (aliasing), then behavior is undefined - except if source and destination regions are identical (including matching strides), which can be used by application to mark that region as dirty (instead of the whole `OSPData`) To add a data array as parameter named `id` to another object call also use void ospSetObject(OSPObject, const char *id, OSPData); Volumes ------- Volumes are volumetric data sets with discretely sampled values in 3D space, typically a 3D scalar field. To create a new volume object of given type `type` use OSPVolume ospNewVolume(const char *type); Note that OSPRay's implementation forwards `type` directly to Open VKL, allowing new Open VKL volume types to be usable within OSPRay without the need to change (or even recompile) OSPRay. ### Structured Regular Volume Structured volumes only need to store the values of the samples, because their addresses in memory can be easily computed from a 3D position. A common type of structured volumes are regular grids. Structured regular volumes are created by passing the type string "`structuredRegular`" to `ospNewVolume`. Structured volumes are represented through an `OSPData` 3D array `data` (which may or may not be shared with the application). The voxel data must be laid out in xyz-order^[For consecutive memory addresses the x-index of the corresponding voxel changes the quickest.] and can be compact (best for performance) or can have a stride between voxels, specified through the `byteStride1` parameter when creating the `OSPData`. Only 1D strides are supported, additional strides between scanlines (2D, `byteStride2`) and slices (3D, `byteStride3`) are not. The parameters understood by structured volumes are summarized in the table below. ------- -------------- ----------------------------- -------------------------- Type Name Default Description ------- -------------- ----------------------------- -------------------------- vec3f gridOrigin $(0, 0, 0)$ origin of the grid in object-space vec3f gridSpacing $(1, 1, 1)$ size of the grid cells in object-space OSPData data the actual voxel 3D [data] bool cellCentered false whether the data is provided per cell (as opposed to per vertex) uint filter `OSP_VOLUME_FILTER_LINEAR` filter used for reconstructing the field, also allowed is `OSP_VOLUME_FILTER_NEAREST` and `OSP_VOLUME_FILTER_CUBIC` uint gradientFilter same as `filter` filter used during gradient computations float background `NaN` value that is used when sampling an undefined region outside the volume domain ------- -------------- ----------------------------- -------------------------- : Configuration parameters for structured regular volumes. The size of the volume is inferred from the size of the 3D array `data`, as is the type of the voxel values (currently supported are: `OSP_UCHAR`, `OSP_SHORT`, `OSP_USHORT`, `OSP_HALF`, `OSP_FLOAT`, and `OSP_DOUBLE`). Data can be provided either per cell or per vertex (the default), selectable via the `cellCentered` parameter (which will also affect the computed bounding box). ### Structured Spherical Volume Structured spherical volumes are also supported, which are created by passing a type string of "`structuredSpherical`" to `ospNewVolume`. The grid dimensions and parameters are defined in terms of radial distance $r$, inclination angle $\theta$, and azimuthal angle $\phi$, conforming with the ISO convention for spherical coordinate systems. The coordinate system and parameters understood by structured spherical volumes are summarized below. ![Coordinate system of structured spherical volumes.][imgStructuredSphericalCoords] ------- -------------- ----------------------------- -------------------------- Type Name Default Description ------- -------------- ----------------------------- -------------------------- vec3f gridOrigin $(0, 0, 0)$ origin of the grid in units of $(r, \theta, \phi)$; angles in degrees vec3f gridSpacing $(1, 180/dim.y, 360/dim.z)$ size of the grid cells in units of $(r, \theta, \phi)$, per default covering the full sphere; angles in degrees OSPData data the actual voxel 3D [data] uint filter `OSP_VOLUME_FILTER_LINEAR` filter used for reconstructing the field, also allowed is `OSP_VOLUME_FILTER_NEAREST` uint gradientFilter same as `filter` filter used during gradient computations float background `NaN` value that is used when sampling an undefined region outside the volume domain ------- -------------- ----------------------------- -------------------------- : Configuration parameters for structured spherical volumes. The dimensions $(r, \theta, \phi)$ of the volume are inferred from the size of the 3D array `data`, as is the type of the voxel values (currently supported are: `OSP_UCHAR`, `OSP_SHORT`, `OSP_USHORT`, `OSP_HALF`, `OSP_FLOAT`, and `OSP_DOUBLE`). These grid parameters support flexible specification of spheres, hemispheres, spherical shells, spherical wedges, and so forth. The grid extents (computed as `[gridOrigin, gridOrigin + (dimensions - 1) * gridSpacing]`) however must be constrained such that: * $r \geq 0$ * $0 \leq \theta \leq 180$ * $0 \leq \phi \leq 360$ ### Adaptive Mesh Refinement (AMR) Volume OSPRay currently supports block-structured (Berger-Colella) AMR volumes. Volumes are specified as a list of blocks, which exist at levels of refinement in potentially overlapping regions. Blocks exist in a tree structure, with coarser refinement level blocks containing finer blocks. The cell width is equal for all blocks at the same refinement level, though blocks at a coarser level have a larger cell width than finer levels. There can be any number of refinement levels and any number of blocks at any level of refinement. An AMR volume type is created by passing the type string "`amr`" to `ospNewVolume`. Blocks are defined by three parameters: their bounds, the refinement level in which they reside, and the scalar data contained within each block. Note that cell widths are defined _per refinement level_, not per block. -------------- --------------- ----------------- ----------------------------------- Type Name Default Description -------------- --------------- ----------------- ----------------------------------- uint method `OSP_AMR_CURRENT` `OSPAMRMethod` sampling method. Supported methods are: `OSP_AMR_CURRENT` `OSP_AMR_FINEST` `OSP_AMR_OCTANT` float[] cellWidth NULL array of each level's cell width box3i[] block.bounds NULL [data] array of grid sizes (in voxels) for each AMR block int[] block.level NULL array of each block's refinement level OSPData[] block.data NULL [data] array of OSPData containing the actual scalar voxel data, only `OSP_FLOAT` is supported as `OSPDataType` vec3f gridOrigin $(0, 0, 0)$ origin of the grid vec3f gridSpacing $(1, 1, 1)$ size of the grid cells float background `NaN` value that is used when sampling an undefined region outside the volume domain -------------- --------------- ----------------- ----------------------------------- : Configuration parameters for AMR volumes. Lastly, note that the `gridOrigin` and `gridSpacing` parameters act just like the structured volume equivalent, but they only modify the root (coarsest level) of refinement. In particular, OSPRay's / Open VKL's AMR implementation was designed to cover Berger-Colella [1]\ and Chombo\ [2] AMR data. The `method` parameter above determines the interpolation method used when sampling the volume. OSP_AMR_CURRENT : finds the finest refinement level at that cell and interpolates through this "current" level OSP_AMR_FINEST : will interpolate at the closest existing cell in the volume-wide finest refinement level regardless of the sample cell's level OSP_AMR_OCTANT : interpolates through all available refinement levels at that cell. This method avoids discontinuities at refinement level boundaries at the cost of performance Details and more information can be found in the publication for the implementation\ [3]. 1. M.J.

DOI: 10.1145/3139295.3139305 ### Unstructured Volume Unstructured volumes can have their topology and geometry freely defined. Geometry can be composed of tetrahedral, hexahedral, wedge or pyramid cell types. The data format used is compatible with VTK and consists of multiple arrays: vertex positions and values, vertex indices, cell start indices, cell types, and cell values. An unstructured volume type is created by passing the type string "`unstructured`" to `ospNewVolume`. Sampled cell values can be specified either per-vertex (`vertex.data`) or per-cell (`cell.data`). If both arrays are set, `cell.data` takes precedence. Similar to a mesh, each cell is formed by a group of indices into the vertices. For each vertex, the corresponding (by array index) data value will be used for sampling when rendering, if specified. The index order for a tetrahedron is the same as `VTK_TETRA`: bottom triangle counterclockwise, then the top vertex. For hexahedral cells, each hexahedron is formed by a group of eight indices into the vertices and data values. Vertex ordering is the same as `VTK_HEXAHEDRON`: four bottom vertices counterclockwise, then top four counterclockwise. For wedge cells, each wedge is formed by a group of six indices into the vertices and data values. Vertex ordering is the same as `VTK_WEDGE`: three bottom vertices counterclockwise, then top three counterclockwise. For pyramid cells, each cell is formed by a group of five indices into the vertices and data values. Vertex ordering is the same as `VTK_PYRAMID`: four bottom vertices counterclockwise, then the top vertex. To maintain VTK data compatibility, the `index` array may be specified with cell sizes interleaved with vertex indices in the following format: $n, id_1, ..., id_n, m, id_1, ..., id_m$. This alternative `index` array layout can be enabled through the `indexPrefixed` flag (in which case, the `cell.type` parameter must be omitted). ------------------- ------------------ -------- --------------------------------------- Type Name Default Description ------------------- ------------------ -------- --------------------------------------- vec3f[] vertex.position [data] array of vertex positions float[] vertex.data [data] array of vertex data values to be sampled uint32[] / uint64[] index [data] array of indices (into the vertex array(s)) that form cells bool indexPrefixed false indicates that the `index` array is compatible to VTK, where the indices of each cell are prefixed with the number of vertices uint32[] / uint64[] cell.index [data] array of locations (into the index array), specifying the first index of each cell float[] cell.data [data] array of cell data values to be sampled uint8[] cell.type [data] array of cell types (VTK compatible), only set if `indexPrefixed = false`. Supported types are: `OSP_TETRAHEDRON` `OSP_HEXAHEDRON` `OSP_WEDGE` `OSP_PYRAMID` bool hexIterative false hexahedron interpolation method, defaults to fast non-iterative version which could have rendering inaccuracies may appear if hex is not parallelepiped bool precomputedNormals false whether to accelerate by precomputing, at a cost of 12 bytes/face float background `NaN` value that is used when sampling an undefined region outside the volume domain ------------------- ------------------ -------- --------------------------------------- : Configuration parameters for unstructured volumes. ### VDB Volume VDB volumes implement a data structure that is very similar to the data structure outlined in Museth\ [1], they are created by passing the type string "`vdb`" to `ospNewVolume`. The data structure is a hierarchical regular grid at its core: Nodes are regular grids, and each grid cell may either store a constant value (this is called a tile), or child pointers. Nodes in VDB trees are wide: Nodes on the first level have a resolution of 32^3^ voxels, on the next level 16^3^, and on the leaf level 8^3^ voxels. All nodes on a given level have the same resolution. This makes it easy to find the node containing a coordinate using shift operations (see\ [1]). VDB leaf nodes are implicit in OSPRay / Open VKL: they are stored as pointers to user-provided data. ![Topology of VDB volumes.][imgVdbStructure] VDB volumes interpret input data as constant cells (which are then potentially filtered). This is in contrast to `structuredRegular` volumes, which have a vertex-centered interpretation. The VDB implementation in OSPRay / Open VKL follows the following goals: - Efficient data structure traversal on vector architectures. - Enable the use of industry-standard `.vdb` files created through the OpenVDB library. - Compatibility with OpenVDB on a leaf data level, so that `.vdb` file may be loaded with minimal overhead. VDB volumes have the following parameters: ---------- ----------------- ------------------------------------------------- Type Name Description ---------- ----------------- ------------------------------------------------- int maxSamplingDepth do not descend further than to this depth during sampling, the maximum value and the default is 3 uint32[] node.level level on which each input node exists, may be 1, 2 or 3 (levels are counted from the root level = 0 down) vec3i[] node.origin the node origin index (per input node) OSPData[] node.data [data] arrays with the node data (per input node). Nodes that are tiles are expected to have single-item arrays. Leaf-nodes with grid data expected to have compact 3D arrays in zyx layout (z changes most quickly) with the correct number of voxels for the `level`. Only `OSP_FLOAT` is supported as field `OSPDataType`. OSPData nodesPackedDense optionally provided instead of `node.data`, a single array of all dense node data in a contiguous zyx layout, provided in the same order as the corresponding `node.*` parameters OSPData nodesPackedTile optionally provided instead of `node.data`, a single array of all tile node data in a contiguous layout, provided in the same order as the corresponding `node.*` parameters uint32[] node.format for each input node, whether it is of format `OSP_VOLUME_FORMAT_DENSE_ZYX` (and thus stored in `nodesPackedDense`), or `OSP_VOLUME_FORMAT_TILE` (stored in `nodesPackedTile`) uint filter filter used for reconstructing the field, default is `OSP_VOLUME_FILTER_LINEAR`, alternatively `OSP_VOLUME_FILTER_NEAREST`, or `OSP_VOLUME_FILTER_CUBIC`. uint gradientFilter filter used for reconstructing the field during gradient computations, default same as `filter` float background value that is used when sampling an undefined region outside the volume domain, default `NaN` ---------- ----------------- ------------------------------------------------- : Configuration parameters for VDB volumes. The `nodesPackedDense` and `nodesPackedTile` together with `node.format` parameters may be provided instead of `node.data`; this packed data layout may provide better performance. 1. Museth, K. VDB: High-Resolution Sparse Volumes with Dynamic Topology. ACM Transactions on Graphics 32(3), 2013. DOI: 10.1145/2487228.2487235 ### Particle Volume Particle volumes consist of a set of points in space. Each point has a position, a radius, and a weight typically associated with an attribute. Particle volumes are created by passing the type string "`particle`" to `ospNewVolume`. A radial basis function defines the contribution of that particle. Currently, we use the Gaussian radial basis function $$\phi(P) = w \exp\left(-\frac{(P - p)^2}{2 r^2}\right),$$ where $P$ is the particle position, $p$ is the sample position, $r$ is the radius and $w$ is the weight. At each sample, the scalar field value is then computed as the sum of each radial basis function $\phi$, for each particle that overlaps it. The OSPRay / Open VKL implementation is similar to direct evaluation of samples in Reda et al.\ [2]. It uses an Embree-built BVH with a custom traversal, similar to the method in\ [1]. -------- ----------------------- -------- --------------------------------------- Type Name Default Description -------- ----------------------- -------- --------------------------------------- vec3f[] particle.position [data] array of particle positions float[] particle.radius [data] array of particle radii float[] particle.weight NULL optional [data] array of particle weights, specifying the height of the kernel. float radiusSupportFactor 3.0 The multiplier of the particle radius required for support. Larger radii ensure smooth results at the cost of performance. In the Gaussian kernel, the radius is one standard deviation ($\sigma$), so a value of 3 corresponds to $3 \sigma$. float clampMaxCumulativeValue 0 The maximum cumulative value possible, set by user. All cumulative values will be clamped to this, and further traversal (RBF summation) of particle contributions will halt when this value is reached. A value of zero or less turns this off. bool estimateValueRanges true Enable heuristic estimation of value ranges which are used in internal acceleration structures as well as for determining the volume's overall value range. When set to `false`, the user *must* specify `clampMaxCumulativeValue`, and all value ranges will be assumed [0–`clampMaxCumulativeValue`]. Disabling this switch may improve volume commit time, but will make volume rendering less efficient. -------- ----------------------- -------- --------------------------------------- : Configuration parameters for particle volumes. 1.

To create a new transfer function of given type `type` use OSPTransferFunction ospNewTransferFunction(const char *type); The returned handle can be assigned to a volumetric model (described below) as parameter "`transferFunction`" using `ospSetObject`. One type of transfer function that is supported by OSPRay is the linear transfer function, which interpolates between given equidistant colors and opacities. It is create by passing the string "`piecewiseLinear`" to `ospNewTransferFunction` and it is controlled by these parameters: Type Name Description ------------ ----------- ---------------------------------------------- vec3f[] color [data] array of colors (linear RGB) float[] opacity [data] array of opacities box1f value domain (scalar range) this function maps from ------------ ----------- ---------------------------------------------- : Parameters accepted by the linear transfer function. The arrays `color` and `opacity` can be of different length. ### VolumetricModels Volumes in OSPRay are given volume rendering appearance information through VolumetricModels. This decouples the physical representation of the volume (and possible acceleration structures it contains) to rendering-specific parameters (where more than one set may exist concurrently). To create a volume instance, call OSPVolumetricModel ospNewVolumetricModel(OSPVolume); The passed volume can be `NULL` as long as the volume to be used is passed as a parameter. If both a volume is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the volume object passed on object creation is again used. -------------------- ----------------- -------- -------------------------------------- Type Name Default Description -------------------- ----------------- -------- -------------------------------------- OSPVolume volume optional [volume] object this model references OSPTransferFunction transferFunction [transfer function] to use float densityScale 1.0 makes volumes uniformly thinner or thicker float anisotropy 0.0 anisotropy of the (Henyey-Greenstein) phase function in [-1–1] ([path tracer] only), default to isotropic scattering uint32 id -1u optional user ID, for [framebuffer] channel `OSP_FB_ID_OBJECT` -------------------- ----------------- -------- --------------------------------------- : Parameters understood by VolumetricModel. Geometries ---------- Geometries in OSPRay are objects that describe intersectable surfaces. To create a new geometry object of given type `type` use OSPGeometry ospNewGeometry(const char *type); Note that in the current implementation geometries are limited to a maximum of 2^32^ primitives. ### Mesh A mesh consisting of either triangles or quads is created by calling `ospNewGeometry` with type string "`mesh`". Once created, a mesh recognizes the following parameters: -------------------- ----------------------- --------------------------------- Type Name Description -------------------- ----------------------- --------------------------------- vec3f[] vertex.position [data] array of vertex positions, overridden by `motion.*` arrays vec3f[] normal [data] array of face-varying normals, overridden by `motion.*` arrays vec3f[] vertex.normal [data] array of vertex-varying normals, overridden by `motion.*` arrays vec4f[] / vec3f[] color [data] array of face-varying colors (linear RGBA/RGB) vec4f[] / vec3f[] vertex.color [data] array of vertex-varying colors (linear RGBA/RGB) vec2f[] texcoord [data] array of face-varying texture coordinates vec2f[] vertex.texcoord [data] array of vertex-varying texture coordinates vec3ui[] / vec4ui[] index [data] array of (either triangle or quad) indices (into the vertex array(s)) bool quadSoup when no explicit `index` is given, indicates whether to assume a 'soup' of quads instead of triangles, default false vec3f[][] motion.vertex.position [data] array of vertex position arrays (uniformly distributed keys for deformation motion blur) vec3f[][] motion.normal [data] array of face-varying normal arrays (uniformly distributed keys for deformation motion blur) vec3f[][] motion.vertex.normal [data] array of vertex-varying normal arrays (uniformly distributed keys for deformation motion blur) box1f time time associated with first and last key in `motion.*` arrays (for deformation motion blur), default [0, 1] -------------------- ----------------------- --------------------------------- : Parameters defining a mesh geometry. The data type of index arrays differentiates between the underlying geometry, triangles are used for a index with `vec3ui` type and quads for `vec4ui` type. Quads are internally handled as a pair of two triangles, thus mixing triangles and quads is supported by encoding some triangle as a quad with the last two vertex indices being identical (`w=z`). The `vertex.position` array is mandatory to create a valid mesh. The `index` array is optional. If none is provided, a 'triangle soup' is assumed, i.e., each three consecutive vertices form one triangle; unless the boolean `quadSoup` is set to true, then a 'quad soup' is assumed i.e., each four subsequent vertices form one quad. If the size of the `vertex.position` array is not a multiple of three for triangles or four for quads, the remainder vertices are ignored. Face-varying attributes (`normal`, `motion.normal`, `color`, `texcoord`) map unique values to each vertex of a primitive/face (triangle or quad), thus attributes can be different for the same vertex that is shared by multiple primitives. Essentially, face-varying attributes are a 'attribute soup' and behave similar to the implicit index, the size of the array must be at least three times the number of triangles or four times the number of quads, respectively. Face-varying attributes take precedence over the respective vertex attributes (`vertex.normal`, `motion.vertex.normal`, `vertex.color`, `vertex.texcoord`) when both arrays of the same attribute are present. ### Subdivision A mesh consisting of subdivision surfaces, created by specifying a geometry of type "`subdivision`". Once created, a subdivision recognizes the following parameters: ------- ------------------- -------------------------------------------------- Type Name Description ------- ------------------- -------------------------------------------------- vec3f[] vertex.position [data] array of vertex positions vec4f[] color optional [data] array of face-varying colors (linear RGBA) vec4f[] vertex.color optional [data] array of vertex-varying colors (linear RGBA) vec2f[] texcoord optional [data] array of vertex-varying texture coordinates vec2f[] vertex.texcoord optional [data] array of vertex-varying texture coordinates float level global level of tessellation, default 5 uint[] index [data] array of indices (into the vertex array(s)) float[] index.level optional [data] array of per-edge levels of tessellation, overrides global level uint[] face optional [data] array holding the number of indices/edges (3 to 15) per face, defaults to 4 (a pure quad mesh) vec2i[] edgeCrease.index optional [data] array of edge crease indices float[] edgeCrease.weight optional [data] array of edge crease weights uint[] vertexCrease.index optional [data] array of vertex crease indices float[] vertexCrease.weight optional [data] array of vertex crease weights uint mode `OSPSubdivisionMode` subdivision edge boundary mode, supported modes are: `OSP_SUBDIVISION_NO_BOUNDARY` `OSP_SUBDIVISION_SMOOTH_BOUNDARY` (default) `OSP_SUBDIVISION_PIN_CORNERS` `OSP_SUBDIVISION_PIN_BOUNDARY` `OSP_SUBDIVISION_PIN_ALL` ------- ------------------- -------------------------------------------------- : Parameters defining a Subdivision geometry. The `vertex` and `index` arrays are mandatory to create a valid subdivision surface. If no `face` array is present then a pure quad mesh is assumed (the number of indices must be a multiple of 4). Optionally supported are edge and vertex creases. ### Spheres A geometry consisting of individual spheres, each of which can have an own radius, is created by calling `ospNewGeometry` with type string "`sphere`". The spheres will not be tessellated but rendered procedurally and are thus perfectly round. To allow a variety of sphere representations in the application this geometry allows a flexible way of specifying the data of center position and radius within a [data] array: -------- ---------------- -------- --------------------------------------- Type Name Default Description -------- ---------------- -------- --------------------------------------- vec3f[] sphere.position [data] array of center positions float[] sphere.radius NULL optional [data] array of the per-sphere radius vec3f[] sphere.normal NULL optional [data](#data) array of normals (only for “oriented discâ€) vec2f[] sphere.texcoord NULL optional [data] array of texture coordinates (constant per sphere) float radius 0.01 default radius for all spheres (if `sphere.radius` is not set) uint type `OSPSphereType` for rendering the sphere. Supported types are: `OSP_SPHERE` (default) `OSP_DISC` `OSP_ORIENTED_DISC` -------- ---------------- -------- --------------------------------------- : Parameters defining a spheres geometry. ### Curves A geometry consisting of multiple curves is created by calling `ospNewGeometry` with type string "`curve`". The parameters defining this geometry are listed in the table below. ------------------ ---------------------- ------------------------------------------- Type Name Description ------------------ ---------------------- ------------------------------------------- vec4f[] vertex.position_radius [data] array of vertex position and per-vertex radius vec2f[] vertex.texcoord [data] array of per-vertex texture coordinates vec4f[] vertex.color [data] array of corresponding vertex colors (linear RGBA) vec3f[] vertex.normal [data] array of curve normals (only for "ribbon" curves) vec4f[] vertex.tangent [data] array of curve tangents (only for "hermite" curves) uint32[] index [data] array of indices to the first vertex or tangent of a curve segment uint type `OSPCurveType` for rendering the curve. Supported types are: `OSP_FLAT` `OSP_ROUND` `OSP_RIBBON` `OSP_DISJOINT` uint basis `OSPCurveBasis` for defining the curve. Supported bases are: `OSP_LINEAR` `OSP_BEZIER` `OSP_BSPLINE` `OSP_HERMITE` `OSP_CATMULL_ROM` ------------------ ---------------------- ------------------------------------------- : Parameters defining a curves geometry. Positions in `vertex.position_radius` parameter supports per-vertex varying radii with data type `vec4f[]` and instantiate Embree curves internally for the relevant type/basis mapping. The following section describes the properties of different curve basis' and how they use the data provided in data buffers: OSP_LINEAR : The indices point to the first of 2 consecutive control points in the vertex buffer. The first control point is the start and the second control point the end of the line segment. The curve goes through all control points listed in the vertex buffer. OSP_BEZIER : The indices point to the first of 4 consecutive control points in the vertex buffer. The first control point represents the start point of the curve, and the 4th control point the end point of the curve. The Bézier basis is interpolating, thus the curve does go exactly through the first and fourth control vertex. OSP_BSPLINE : The indices point to the first of 4 consecutive control points in the vertex buffer. This basis is not interpolating, thus the curve does in general not go through any of the control points directly. Using this basis, 3 control points can be shared for two continuous neighboring curve segments, e.g., the curves $(p0, p1, p2, p3)$ and $(p1, p2, p3, p4)$ are C1 continuous. This feature make this basis a good choice to construct continuous multi-segment curves, as memory consumption can be kept minimal. OSP_HERMITE : It is necessary to have both vertex buffer and tangent buffer for using this basis. The indices point to the first of 2 consecutive points in the vertex buffer, and the first of 2 consecutive tangents in the tangent buffer. This basis is interpolating, thus does exactly go through the first and second control point, and the first order derivative at the begin and end matches exactly the value specified in the tangent buffer. When connecting two segments continuously, the end point and tangent of the previous segment can be shared. OSP_CATMULL_ROM : The indices point to the first of 4 consecutive control points in the vertex buffer. If $(p0, p1, p2, p3)$ represent the points then this basis goes through $p1$ and $p2$, with tangents as $(p2-p0)/2$ and $(p3-p1)/2$. The following section describes the properties of different curve types' and how they define the geometry of a curve: OSP_FLAT : This type enables faster rendering as the curve is rendered as a connected sequence of ray facing quads. OSP_ROUND : This type enables rendering a real geometric surface for the curve which allows closeup views. This mode renders a sweep surface by sweeping a varying radius circle tangential along the curve. OSP_RIBBON : The type enables normal orientation of the curve and requires a normal buffer be specified along with vertex buffer. The curve is rendered as a flat band whose center approximately follows the provided vertex buffer and whose normal orientation approximately follows the provided normal buffer. Not supported for basis `OSP_LINEAR`. OSP_DISJOINT : Only supported for basis `OSP_LINEAR`; the segments are open and not connected at the joints, i.e., the curve segments are either individual cones or cylinders. ### Boxes OSPRay can directly render axis-aligned bounding boxes without the need to convert them to quads or triangles. To do so create a boxes geometry by calling `ospNewGeometry` with type string "`box`". Type Name Description ---------- ---------- ------------------------------------------------------ box3f[] box [data] array of boxes ---------- ---------- ------------------------------------------------------ : Parameters defining a boxes geometry. ### Planes OSPRay can directly render planes defined by plane equation coefficients in its implicit form $ax + by + cz + d = 0$. By default planes are infinite but their extents can be limited by defining optional bounding boxes. A planes geometry can be created by calling `ospNewGeometry` with type string "`plane`". Type Name Description ---------- ------------------ ------------------------------------------------- vec4f[] plane.coefficients [data] array of plane coefficients $(a, b, c, d)$ box3f[] plane.bounds optional [data] array of bounding boxes ---------- ------------------ ------------------------------------------------- : Parameters defining a planes geometry. ### Isosurfaces OSPRay can directly render multiple isosurfaces of a volume without first tessellating them. To do so create an isosurfaces geometry by calling `ospNewGeometry` with type string "`isosurface`". The appearance information of the surfaces is set through the Geometric Model. Per-isosurface colors can be set by passing per-primitive colors to the Geometric Model, in order of the isosurface array. Type Name Description ------------------ --------- -------------------------------------------------- float isovalue single isovalues float[] isovalue [data] array of isovalues OSPVolume volume handle of the [Volume] to be isosurfaced ------------------ --------- -------------------------------------------------- : Parameters defining an isosurfaces geometry. ### GeometricModels Geometries are matched with surface appearance information through GeometricModels. These take a geometry, which defines the surface representation, and applies either full-object or per-primitive color and material information. To create a geometric model, call OSPGeometricModel ospNewGeometricModel(OSPGeometry); The passed geometry can be `NULL` as long as the geometry to be used is passed as a parameter. If both a geometry is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the geometry object passed on object creation is again used. Color and material are fetched with the primitive ID of the hit (clamped to the valid range, thus a single color or material is fine), or mapped first via the `index` array (if present). All parameters are optional, however, some renderers (notably the [path tracer]) require a material to be set. Materials are either handles of `OSPMaterial`, or indices into the `material` array on the [renderer], which allows to build a [world] which can be used by different types of renderers. An `invertNormals` flag allows to invert (shading) normal vectors of the rendered geometry. That is particularly useful for clipping. By changing normal vectors orientation one can control whether inside or outside of the clipping geometry is being removed. For example, a clipping geometry with normals oriented outside clips everything what's inside. ----------------------------------------------- ------------- ---------------------------------------------------- Type Name Description ----------------------------------------------- ------------- ---------------------------------------------------- OSPGeometry geometry optional [geometry] object this model references OSPMaterial / OSPMaterial[] / uint32 / uint32[] material optional ([data] array of per-primitive) [material], may be an index into the `material` parameter on the renderer (if it exists) vec4f / vec4f[] color optional ([data] array of per-primitive) color assigned to the geometry (linear RGBA) uint8[] index optional [data] array of per-primitive indices into `color` and `material` bool invertNormals inverts all shading normals (Ns), default false uint32 id optional user ID, for [framebuffer] channel `OSP_FB_ID_OBJECT`, default -1u ----------------------------------------------- ------------- ---------------------------------------------------- : Parameters understood by GeometricModel. Lights ------ To create a new light source of given type `type` use OSPLight ospNewLight(const char *type); All light sources accept the following parameters: --------- ------------------ -------- -------------------------------------------- Type Name Default Description --------- ------------------ -------- -------------------------------------------- vec3f color white color of the light (linear RGB) float intensity 1 intensity of the light (a factor) uint intensityQuantity `OSPIntensityQuantity` to set the radiometric quantity represented by `intensity`. The default value depends on the light source. bool visible true whether the light can be directly seen --------- ------------------ -------- -------------------------------------------- : Parameters accepted by all lights. In OSPRay the `intensity` parameter of a light source can correspond to different types of radiometric quantities. The type of the value represented by a light's `intensity` parameter is set using `intensityQuantity`, which accepts values from the enum type `OSPIntensityQuantity`. The supported types of `OSPIntensityQuantity` differ between the different light sources (see documentation of each specific light source). ---------------------------------- ---------------------------------------------------- Name Description ---------------------------------- ---------------------------------------------------- OSP_INTENSITY_QUANTITY_POWER the overall amount of light energy emitted by the light source into the scene, unit is W OSP_INTENSITY_QUANTITY_INTENSITY the overall amount of light emitted by the light in a given direction, unit is W/sr OSP_INTENSITY_QUANTITY_RADIANCE the amount of light emitted by a point on the light source in a given direction, unit is W/sr/m^2^ OSP_INTENSITY_QUANTITY_IRRADIANCE the amount of light arriving at a surface point, assuming the light is oriented towards to the surface, unit is W/m^2^ OSP_INTENSITY_QUANTITY_SCALE a linear scaling factor for light sources with a built-in quantity (e.g., `HDRI`, or `sunSky`, or when using `intensityDistribution`). ---------------------------------- ---------------------------------------------------- : Types of radiometric quantities used to interpret a light's `intensity` parameter. ### Photometric Lights Measured light sources (IES, EULUMDAT, ...) are supported by the `sphere`, `spot`, and `quad` lights when setting an `intensityDistribution` [data] array to modulate the intensity per direction. The mapping is using the C-γ coordinate system (see also below figure): the values of the first (or only) dimension of `intensityDistribution` are uniformly mapped to γ in [0–π]; the first intensity value to 0, the last value to Ï€, thus at least two values need to be present. ![C-γ coordinate system for the mapping of `intensityDistribution` with photometric lights.][imgCGammaCoords] If the array has a second dimension then the intensities are not rotational symmetric around the main direction (where angle γ is zero), but are accordingly mapped to the C-halfplanes in [0–2Ï€]; the first "row" of values to 0 and 2Ï€, the other rows such that they have uniform distance to its neighbors. The orientation of the C0-plane is specified via `c0`. ---------- --------------------- --------------------------------------------- Type Name Description ---------- --------------------- --------------------------------------------- float[] intensityDistribution luminous intensity distribution for photometric lights; can be 2D for asymmetric illumination; values are assumed to be uniformly distributed vec3f c0 orientation, i.e., direction of the C0-(half)plane (only needed if illumination via `intensityDistribution` is asymmetric) ---------- --------------------- --------------------------------------------- : Special parameters for photometric lights. When using an `intensityDistribution` then the default and only valid value for `intensityQuantity` is `OSP_INTENSITY_QUANTITY_SCALE`. The following light types are supported by most OSPRay renderers. ### Directional Light / Distant Light The distant light (or traditionally the directional light) is thought to be far away (outside of the scene), thus its light arrives (almost) as parallel rays. It is created by passing the type string "`distant`" to `ospNewLight`. The distant light supports `OSP_INTENSITY_QUANTITY_RADIANCE` and `OSP_INTENSITY_QUANTITY_IRRADIANCE` (default) as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights the distant light supports the following special parameters: Type Name Default Description --------- ---------------- ------------ --------------------------------------------- vec3f direction $(0, 0, 1)$ main emission direction of the distant light float angularDiameter 0 apparent size (angle in degree) of the light --------- ---------------- ------------ --------------------------------------------- : Special parameters accepted by the distant light. Setting the angular diameter to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer]). For instance, the apparent size of the sun is about 0.53°. ### Point Light / Sphere Light The sphere light (or the special case point light) is a light emitting uniformly in all directions from the surface toward the outside. It does not emit any light toward the inside of the sphere. It is created by passing the type string "`sphere`" to `ospNewLight`. The point light supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` (then default) and `OSP_INTENSITY_QUANTITY_RADIANCE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the sphere light supports the following special parameters: Type Name Default Description ------- ---------- ------------ -------------------------------- vec3f position $(0, 0, 0)$ the center of the sphere light float radius 0 the size of the sphere light vec3f direction $(0, 0, 1)$ main orientation of `intensityDistribution` ------- ---------- ------------ -------------------------------- : Special parameters accepted by the sphere light. Setting the radius to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer]). ### Spotlight / Ring Light The spotlight is a light emitting into a cone of directions. It is created by passing the type string "`spot`" to `ospNewLight`. The spotlight supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` (then default) and `OSP_INTENSITY_QUANTITY_RADIANCE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the spotlight supports the special parameters listed in the table. ---------- --------------------- ----------- --------------------------------- Type Name Default Description ---------- --------------------- ----------- --------------------------------- vec3f position $(0, 0, 0)$ the center of the spotlight vec3f direction $(0, 0, 1)$ main emission direction of the spot float openingAngle 180 full opening angle (in degree) of the spot; outside of this cone is no illumination float penumbraAngle 5 size (angle in degree) of the "penumbra", the region between the rim (of the illumination cone) and full intensity of the spot; should be smaller than half of `openingAngle` float radius 0 the size of the spotlight, the radius of a disk with normal `direction` float innerRadius 0 in combination with `radius` turns the disk into a ring ---------- --------------------- ----------- --------------------------------- : Special parameters accepted by the spotlight. ![Angles used by the spotlight.][imgSpotLight] Setting the radius to a value greater than zero will result in soft shadows when the renderer uses stochastic sampling (like the [path tracer]). Additionally setting the inner radius will result in a ring instead of a disk emitting the light. ### Quad Light The quad^[actually a parallelogram] light is a planar, procedural area light source emitting uniformly on one side into the half-space. It is created by passing the type string "`quad`" to `ospNewLight`. The quad light supports only `OSP_INTENSITY_QUANTITY_SCALE` when `intensityDistribution` is set, or otherwise `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` and `OSP_INTENSITY_QUANTITY_RADIANCE` (then default) as `intensityQuantity` parameter. In addition to the [general parameters](#lights) understood by all lights and the [photometric parameters](#photometric-lights) the quad light supports the following special parameters: Type Name Default Description ------ --------- ------------ ----------------------------------------- vec3f position $(0, 0, 0)$ position of one vertex of the quad light vec3f edge1 $(1, 0, 0)$ vector to one adjacent vertex vec3f edge2 $(0, 1, 0)$ vector to the other adjacent vertex ------ --------- ------------ ----------------------------------------- : Special parameters accepted by the quad light. ![Defining a quad light which emits toward the reader.][imgQuadLight] The emission side is determined by the cross product of `edge1`×`edge2`. which is also the main emission direction for `intensityDistribution`. Note that only renderers that use stochastic sampling (like the path tracer) will compute soft shadows from the quad light. Other renderers will just sample the center of the quad light, which results in hard shadows. ### Cylinder Light The cylinder light is a cylinderical, procedural area light source emitting uniformly outwardly into the space beyond the boundary. It is created by passing the type string "`cylinder`" to `ospNewLight`. The cylinder light supports `OSP_INTENSITY_QUANTITY_POWER`, `OSP_INTENSITY_QUANTITY_INTENSITY` and `OSP_INTENSITY_QUANTITY_RADIANCE` (default) as `intensityQuantity` parameter. In addition to the [general parameters](#lights) understood by all lights the cylinder light supports the following special parameters: Type Name Default Description ------- ----------- ------------ -------------------------------------- vec3f position0 $(0, 0, 0)$ position of the start of the cylinder vec3f position1 $(0, 0, 1)$ position of the end of the cylinder float radius 1 radius of the cylinder ------- ----------- ------------ -------------------------------------- : Special parameters accepted by the cylinder light. Note that only renderers that use stochastic sampling (like the path tracer) will compute soft shadows from the cylinder light. Other renderers will just sample the closest point on the cylinder light, which results in hard shadows. ### HDRI Light The HDRI light is a textured light source surrounding the scene and illuminating it from infinity. It is created by passing the type string "`hdri`" to `ospNewLight`. The values of the HDRI correspond to radiance and therefore the HDRI light only accepts `OSP_INTENSITY_QUANTITY_SCALE` as `intensityQuantity` parameter value. In addition to the [general parameters](#lights) the HDRI light supports the following special parameters: ------------ --------- ------------ -------------------------------------------------- Type Name Default Description ------------ --------- ------------ -------------------------------------------------- vec3f up $(0, 1, 0)$ up direction of the light vec3f direction $(0, 0, 1)$ direction to which the center of the texture will be mapped to (analog to [panoramic camera]) OSPTexture map environment map in latitude / longitude format ------------ --------- ------------ -------------------------------------------------- : Special parameters accepted by the HDRI light. ![Orientation and Mapping of an HDRI Light.][imgHDRILight] Note that the [SciVis renderer] only shows the HDRI light in the background (like an environment map) without computing illumination of the scene. ### Ambient Light The ambient light surrounds the scene and illuminates it from infinity with constant radiance (determined by combining the [parameters `color` and `intensity`](#lights)). It is created by passing the type string "`ambient`" to `ospNewLight`. The ambient light supports `OSP_INTENSITY_QUANTITY_RADIANCE` and `OSP_INTENSITY_QUANTITY_IRRADIANCE` (default) as `intensityQuantity` parameter value. Note that the [SciVis renderer] uses ambient lights to control the color and intensity of the computed ambient occlusion (AO). ### Sun-Sky Light The sun-sky light is a combination of a `distant` light for the sun and a procedural `hdri` light for the sky. It is created by passing the type string "`sunSky`" to `ospNewLight`. The sun-sky light surrounds the scene and illuminates it from infinity and can be used for rendering outdoor scenes. The radiance values are calculated using the HoÅ¡ek-Wilkie sky model and solar radiance function. The underlying model of the sun-sky light returns radiance values and therefore the light only accepts `OSP_INTENSITY_QUANTITY_SCALE` as `intensityQuantity` parameter value. To rescale the returned radiance of the sky model the default value for the `intensity` parameter is set to `0.025`. In addition to the [general parameters](#lights) the following special parameters are supported: --------- ---------------- ------------ ------------------------------------- Type Name Default Description --------- ---------------- ------------ ------------------------------------- vec3f up $(0, 1, 0)$ zenith of sky vec3f direction $(0, -1, 0)$ main emission direction of the sun float turbidity 3 atmospheric turbidity due to particles, in [1–10] float albedo 0.3 ground reflectance, in [0–1] float horizonExtension 0.01 extend the sky dome by stretching the horizon, fraction of the lower hemisphere to cover, in [0–1] --------- ---------------- ------------ ------------------------------------- : Special parameters accepted by the `sunSky` light. The lowest elevation for the sun is restricted to the horizon. Note that the [SciVis renderer] only computes illumination from the sun (yet the sky is still shown in the background, like an environment map). ### Emissive Objects The [path tracer] will consider illumination by [geometries] which have a light emitting material assigned (for example the [Luminous] or [Principled] material). Materials --------- Materials describe how light interacts with surfaces, they give objects their distinctive look. To create a new material of given type `type` call OSPMaterial ospNewMaterial(const char *material_type); The returned handle can then be used to assign the material to a given geometry with void ospSetObject(OSPGeometricModel, "material", OSPMaterial); ### OBJ Material The OBJ material is the workhorse material supported by both the [SciVis renderer] and the [path tracer] (the [Ambient Occlusion renderer] only uses the `kd` and `d` parameter). It offers widely used common properties like diffuse and specular reflection and is based on the [MTL material format](http://paulbourke.net/dataformats/mtl/) of Lightwave's OBJ scene files. To create an OBJ material pass the type string "`obj`" to `ospNewMaterial`. Its main parameters are Type Name Default Description ------------- --------- ---------- ----------------------------------------- vec3f kd white 0.8 diffuse color (linear RGB) vec3f ks black specular color (linear RGB) float ns 10 shininess (Phong exponent), usually in \[2–10^4^\] float d opaque opacity vec3f tf black transparency filter color (linear RGB) OSPTexture map_bump NULL normal map ------------- --------- ---------- ----------------------------------------- : Main parameters of the OBJ material. In particular when using the path tracer it is important to adhere to the principle of energy conservation, i.e., that the amount of light reflected by a surface is not larger than the light arriving. Therefore the path tracer issues a warning and renormalizes the color parameters if the sum of `kd`, `ks`, and `tf` is larger than one in any color channel. Similarly important to mention is that almost all materials of the real world reflect at most only about 80% of the incoming light. So even for a white sheet of paper or white wall paint do better not set `kd` larger than 0.8; otherwise rendering times are unnecessary long and the contrast in the final images is low (for example, the corners of a white room would hardly be discernible, as can be seen in the figure below). ![Comparison of diffuse rooms with 100% reflecting white paint (left) and realistic 80% reflecting white paint (right), which leads to higher overall contrast. Note that exposure has been adjusted to achieve similar brightness levels.][imgDiffuseRooms] If present, the color component of [geometries] is also used for the diffuse color `kd` and the alpha component is also used for the opacity `d`. Normal mapping can simulate small geometric features via the texture `map_bump`. The normals $n$ in the normal map are with respect to the local tangential shading coordinate system and are encoded as $½(n+1)$, thus a texel $(0.5, 0.5, 1)$^[respectively $(127, 127, 255)$ for 8\ bit textures and $(32767, 32767, 65535)$ for 16\ bit textures] represents the unperturbed shading normal $(0, 0, 1)$. Because of this encoding an sRGB gamma [texture] format is ignored and normals are always fetched as linear from a normal map. Note that the orientation of normal maps is important for a visually consistent look: by convention OSPRay uses a coordinate system with the origin in the lower left corner; thus a convexity will look green toward the top of the texture image (see also the example image of a normal map). If this is not the case flip the normal map vertically or invert its green channel. ![Normal map representing an exalted square pyramidal frustum.][imgNormalMap] Note that `tf` colored transparency is implemented in the SciVis and the path tracer but normal mapping with `map_bump` is currently supported in the path tracer only. All parameters (except `tf`) can be textured by passing a [texture] handle, prefixed with "`map_`". The fetched texels are multiplied by the respective parameter value. If only the texture is given (but not the corresponding parameter), only the texture is used (the default value of the parameter is *not* multiplied). The color textures `map_kd` and `map_ks` are typically in one of the sRGB gamma encoded formats, whereas textures `map_ns` and `map_d` are usually in a linear format (and only the first component is used). Additionally, all textures support [texture transformations]. ![Rendering of a OBJ material with wood textures.][imgMaterialOBJ] ### Principled The Principled material is the most complex material offered by the [path tracer], which is capable of producing a wide variety of materials (e.g., plastic, metal, wood, glass) by combining multiple different layers and lobes. It uses the GGX microfacet distribution with approximate multiple scattering for dielectrics and metals, uses the Oren-Nayar model for diffuse reflection, and is energy conserving. To create a Principled material, pass the type string "`principled`" to `ospNewMaterial`. Its parameters are listed in the table below. ------ ----------------- ---------- ------------------------------------------------------ Type Name Default Description ------ ----------------- ---------- ------------------------------------------------------ vec3f baseColor white 0.8 base reflectivity (diffuse and/or metallic, linear RGB) vec3f edgeColor white edge tint (metallic only, linear RGB) float metallic 0 mix between dielectric (diffuse and/or specular) and metallic (specular only with complex IOR) in [0–1] float diffuse 1 diffuse reflection weight in [0–1] float specular 1 specular reflection/transmission weight in [0–1] float ior 1 dielectric index of refraction float transmission 0 specular transmission weight in [0–1] vec3f transmissionColor white attenuated color due to transmission (Beer's law, linear RGB) float transmissionDepth 1 distance at which color attenuation is equal to transmissionColor float roughness 0 diffuse and specular roughness in [0–1], 0 is perfectly smooth float anisotropy 0 amount of specular anisotropy in [0–1] float rotation 0 rotation of the direction of anisotropy in [0–1], 1 is going full circle float normal 1 default normal map/scale for all layers float baseNormal 1 base normal map/scale (overrides default normal) bool thin false flag specifying whether the material is thin or solid float thickness 1 thickness of the material (thin only), affects the amount of color attenuation due to specular transmission float backlight 0 amount of diffuse transmission (thin only) in [0–2], 1 is 50% reflection and 50% transmission, 2 is transmission only float coat 0 clear coat layer weight in [0–1] float coatIor 1.5 clear coat index of refraction vec3f coatColor white clear coat color tint (linear RGB) float coatThickness 1 clear coat thickness, affects the amount of color attenuation float coatRoughness 0 clear coat roughness in [0–1], 0 is perfectly smooth float coatNormal 1 clear coat normal map/scale (overrides default normal) float sheen 0 sheen layer weight in [0–1] vec3f sheenColor white sheen color tint (linear RGB) float sheenTint 0 how much sheen is tinted from sheenColor toward baseColor float sheenRoughness 0.2 sheen roughness in [0–1], 0 is perfectly smooth float opacity 1 cut-out opacity/transparency, 1 is fully opaque vec3f emissiveColor black color (and intensity) of the emitted light ------ ----------------- ---------- ------------------------------------------------------ : Parameters of the Principled material. All parameters can be textured by passing a [texture] handle, prefixed with "`map_`" (e.g., "`map_baseColor`"). [texture transformations] are supported as well. ![Rendering of a Principled coated brushed metal material with textured anisotropic rotation and a dust layer (sheen) on top.][imgMaterialPrincipled] ### CarPaint The CarPaint material is a specialized version of the Principled material for rendering different types of car paints. To create a CarPaint material, pass the type string "`carPaint`" to `ospNewMaterial`. Its parameters are listed in the table below. ------ ----------------- ---------- ------------------------------------------------------ Type Name Default Description ------ ----------------- ---------- ------------------------------------------------------ vec3f baseColor white 0.8 diffuse base reflectivity (linear RGB) float roughness 0 diffuse roughness in [0–1], 0 is perfectly smooth float normal 1 normal map/scale vec3f flakeColor Aluminium color of metallic flakes (linear RGB) float flakeDensity 0 density of metallic flakes in [0–1], 0 disables flakes, 1 fully covers the surface with flakes float flakeScale 100 scale of the flake structure, higher values increase the amount of flakes float flakeSpread 0.3 flake spread in [0–1] float flakeJitter 0.75 flake randomness in [0–1] float flakeRoughness 0.3 flake roughness in [0–1], 0 is perfectly smooth float coat 1 clear coat layer weight in [0–1] float coatIor 1.5 clear coat index of refraction vec3f coatColor white clear coat color tint (linear RGB) float coatThickness 1 clear coat thickness, affects the amount of color attenuation float coatRoughness 0 clear coat roughness in [0–1], 0 is perfectly smooth float coatNormal 1 clear coat normal map/scale vec3f flipflopColor white reflectivity of coated flakes at grazing angle, used together with coatColor produces a pearlescent paint (linear RGB) float flipflopFalloff 1 flip flop color falloff, 1 disables the flip flop effect ------------------------------------------------------------------------------------------- : Parameters of the CarPaint material. All parameters can be textured by passing a [texture] handle, prefixed with "`map_`" (e.g., "`map_baseColor`"). [texture transformations] are supported as well. ![Rendering of a pearlescent CarPaint material.][imgMaterialCarPaint] ### Metal The [path tracer] offers a physical metal, supporting changing roughness and realistic color shifts at edges. To create a Metal material pass the type string "`metal`" to `ospNewMaterial`. Its parameters are -------- ---------- ---------- -------------------------------------------- Type Name Default Description -------- ---------- ---------- -------------------------------------------- vec3f[] ior Aluminium [data] array of spectral samples of complex refractive index, each entry in the form (wavelength, eta, k), ordered by wavelength (which is in nm) vec3f eta RGB complex refractive index, real part vec3f k RGB complex refractive index, imaginary part float roughness 0.1 roughness in [0–1], 0 is perfect mirror -------- ---------- ---------- -------------------------------------------- : Parameters of the Metal material. The main appearance (mostly the color) of the Metal material is controlled by the physical parameters `eta` and `k`, the wavelength-dependent, complex index of refraction. These coefficients are quite counter-intuitive but can be found in [published measurements](https://refractiveindex.info/). For accuracy the index of refraction can be given as an array of spectral samples in `ior`, each sample a triplet of wavelength (in nm), eta, and k, ordered monotonically increasing by wavelength; OSPRay will then calculate the Fresnel in the spectral domain. Alternatively, `eta` and `k` can also be specified as approximated RGB coefficients; some examples are given in below table. Metal eta k -------------- ----------------------- ----------------- Ag, Silver (0.051, 0.043, 0.041) (5.3, 3.6, 2.3) Al, Aluminium (1.5, 0.98, 0.6) (7.6, 6.6, 5.4) Au, Gold (0.07, 0.37, 1.5) (3.7, 2.3, 1.7) Cr, Chromium (3.2, 3.1, 2.3) (3.3, 3.3, 3.1) Cu, Copper (0.1, 0.8, 1.1) (3.5, 2.5, 2.4) -------------- ----------------------- ----------------- : Index of refraction of selected metals as approximated RGB coefficients, based on data from https://refractiveindex.info/. The `roughness` parameter controls the variation of microfacets and thus how polished the metal will look. The roughness can be modified by a [texture] `map_roughness` ([texture transformations] are supported as well) to create notable edging effects. ![Rendering of golden Metal material with textured roughness.][imgMaterialMetal] ### Alloy The [path tracer] offers an alloy material, which behaves similar to [Metal], but allows for more intuitive and flexible control of the color. To create an Alloy material pass the type string "`alloy`" to `ospNewMaterial`. Its parameters are Type Name Default Description ------ ---------- ---------- -------------------------------------------------------- vec3f color white 0.9 reflectivity at normal incidence (0 degree, linear RGB) vec3f edgeColor white reflectivity at grazing angle (90 degree, linear RGB) float roughness 0.1 roughness, in [0–1], 0 is perfect mirror ------ ---------- ---------- -------------------------------------------------------- : Parameters of the Alloy material. The main appearance of the Alloy material is controlled by the parameter `color`, while `edgeColor` influences the tint of reflections when seen at grazing angles (for real metals this is always 100% white). If present, the color component of [geometries] is also used for reflectivity at normal incidence `color`. As in [Metal] the `roughness` parameter controls the variation of microfacets and thus how polished the alloy will look. All parameters can be textured by passing a [texture] handle, prefixed with "`map_`"; [texture transformations] are supported as well. ![Rendering of a fictional Alloy material with textured color.][imgMaterialAlloy] ### Glass The [path tracer] offers a realistic a glass material, supporting refraction and volumetric attenuation (i.e., the transparency color varies with the geometric thickness). To create a Glass material pass the type string "`glass`" to `ospNewMaterial`. Its parameters are Type Name Default Description ------ -------------------- -------- ----------------------------------------------- float eta 1.5 index of refraction vec3f attenuationColor white resulting color due to attenuation (linear RGB) float attenuationDistance 1 distance affecting attenuation ------ -------------------- -------- ----------------------------------------------- : Parameters of the Glass material. For convenience, the rather counter-intuitive physical attenuation coefficients will be calculated from the user inputs in such a way, that the `attenuationColor` will be the result when white light traveled through a glass of thickness `attenuationDistance`. ![Rendering of a Glass material with orange attenuation.][imgMaterialGlass] ### ThinGlass The [path tracer] offers a thin glass material useful for objects with just a single surface, most prominently windows. It models a thin, transparent slab, i.e., it behaves as if a second, virtual surface is parallel to the real geometric surface. The implementation accounts for multiple internal reflections between the interfaces (including attenuation), but neglects parallax effects due to its (virtual) thickness. To create a such a thin glass material pass the type string "`thinGlass`" to `ospNewMaterial`. Its parameters are Type Name Default Description --------- -------------------- -------- ------------------------------------------------ float eta 1.5 index of refraction vec3f attenuationColor white resulting color due to attenuation (linear RGB) float attenuationDistance 1 distance affecting attenuation float thickness 1 virtual thickness --------- -------------------- -------- ------------------------------------------------ : Parameters of the ThinGlass material. For convenience the attenuation is controlled the same way as with the [Glass] material. Additionally, the color due to attenuation can be modulated with a [texture] `map_attenuationColor` ([texture transformations] are supported as well). If present, the color component of [geometries] is also used for the attenuation color. The `thickness` parameter sets the (virtual) thickness and allows for easy exchange of parameters with the (real) [Glass] material; internally just the ratio between `attenuationDistance` and `thickness` is used to calculate the resulting attenuation and thus the material appearance. ![Rendering of a ThinGlass material with red attenuation.][imgMaterialThinGlass] ![Example image of a colored window made with textured attenuation of the ThinGlass material.][imgColoredWindow] ### MetallicPaint The [path tracer] offers a metallic paint material, consisting of a base coat with optional flakes and a clear coat. To create a MetallicPaint material pass the type string "`metallicPaint`" to `ospNewMaterial`. Its parameters are listed in the table below. Type Name Default Description --------- ------------ ---------- -------------------------------------- vec3f baseColor white 0.8 color of base coat (linear RGB) float flakeAmount 0.3 amount of flakes, in [0–1] vec3f flakeColor Aluminium color of metallic flakes (linear RGB) float flakeSpread 0.5 spread of flakes, in [0–1] float eta 1.5 index of refraction of clear coat --------- ------------ ---------- -------------------------------------- : Parameters of the MetallicPaint material. The color of the base coat `baseColor` can be textured by a [texture] `map_baseColor`, which also supports [texture transformations]. If present, the color component of [geometries] is also used for the color of the base coat. Parameter `flakeAmount` controls the proportion of flakes in the base coat, so when setting it to 1 the `baseColor` will not be visible. The shininess of the metallic component is governed by `flakeSpread`, which controls the variation of the orientation of the flakes, similar to the `roughness` parameter of [Metal]. Note that the effect of the metallic flakes is currently only computed on average, thus individual flakes are not visible. ![Rendering of a MetallicPaint material.][imgMaterialMetallicPaint] ### Luminous The [path tracer] supports the Luminous material which emits light uniformly in all directions and which can thus be used to turn any geometric object into a light source. It is created by passing the type string "`luminous`" to `ospNewMaterial`. The amount of constant radiance that is emitted is determined by combining the general parameters of lights: [`color` and `intensity`](#lights) (which essentially means that parameter `intensityQuantity` is not needed because it is always `OSP_INTENSITY_QUANTITY_RADIANCE`). Type Name Default Description ------ ------------ -------- --------------------------------------- vec3f color white color of the emitted light (linear RGB) float intensity 1 intensity of the light (a factor) float transparency 0 material transparency ------ ------------ -------- --------------------------------------- : Parameters accepted by the Luminous material. The emission can be textured by passing a `map_color` [texture] handle, [texture transformations] are supported as well. ![Rendering of a yellow Luminous material.][imgMaterialLuminous] Texture ------- OSPRay currently implements two texture types (`texture2d` and `volume`) and is open for extension to other types by applications. More types may be added in future releases. To create a new texture use OSPTexture ospNewTexture(const char *type); ### Texture2D The `texture2d` texture type implements an image-based texture, where its parameters are as follows Type Name Description -------------- --------- ---------------------------------- uint format `OSPTextureFormat` for the texture uint filter default `OSP_TEXTURE_FILTER_LINEAR`, alternatively `OSP_TEXTURE_FILTER_NEAREST` OSPData data the actual texel 2D [data] uint / vec2ui wrapMode `OSPTextureWrapMode` for the texture coordinates s and t; supported wrap modes are: `OSP_TEXTURE_WRAP_REPEAT` (default) `OSP_TEXTURE_WRAP_MIRRORED_REPEAT` `OSP_TEXTURE_WRAP_CLAMP_TO_EDGE` -------------- --------- ---------------------------------- : Parameters of `texture2d` texture type. The supported texture formats for `texture2d` are: Name Description ------------------- ---------------------------------------------------------- OSP_TEXTURE_RGBA8 8\ bit [0–255] linear components red, green, blue, alpha OSP_TEXTURE_SRGBA 8\ bit sRGB gamma encoded color components, and linear alpha OSP_TEXTURE_RGBA32F 32\ bit float components red, green, blue, alpha OSP_TEXTURE_RGBA16F 16\ bit float components red, green, blue, alpha OSP_TEXTURE_RGB8 8\ bit [0–255] linear components red, green, blue OSP_TEXTURE_SRGB 8\ bit sRGB gamma encoded components red, green, blue OSP_TEXTURE_RGB32F 32\ bit float components red, green, blue OSP_TEXTURE_RGB16F 16\ bit float components red, green, blue OSP_TEXTURE_R8 8\ bit [0–255] linear single component red OSP_TEXTURE_RA8 8\ bit [0–255] linear two components red, alpha OSP_TEXTURE_L8 8\ bit [0–255] gamma encoded luminance (replicated into red, green, blue) OSP_TEXTURE_LA8 8\ bit [0–255] gamma encoded luminance, and linear alpha OSP_TEXTURE_RA32F 32\ bit float two component red, alpha OSP_TEXTURE_R32F 32\ bit float single component red OSP_TEXTURE_RA16F 16\ bit float two component red, alpha OSP_TEXTURE_R16F 16\ bit float single component red OSP_TEXTURE_RGBA16 16\ bit [0–65535] linear components red, green, blue, alpha OSP_TEXTURE_RGB16 16\ bit [0–65535] linear components red, green, blue OSP_TEXTURE_RA16 16\ bit [0–65535] linear two components red, alpha OSP_TEXTURE_R16 16\ bit [0–65535] linear single component red ------------------- ---------------------------------------------------------- : Supported texture formats by `texture2d`, i.e., valid constants of type `OSPTextureFormat`. The size of the texture is inferred from the size of the 2D array `data`, which also needs have a compatible type to `format`. The texel data in `data` starts with the texels in the lower left corner of the texture image, like in OpenGL. Per default a texture fetch is filtered by performing bi-linear interpolation of the nearest 2×2 texels; if instead fetching only the nearest texel is desired (i.e., no filtering) then pass the `OSP_TEXTURE_FILTER_NEAREST` flag. Texturing with `texture2d` image textures requires [geometries] with texture coordinates, e.g., a [mesh] with `vertex.texcoord` provided. ### Volume Texture The `volume` texture type implements texture lookups based on 3D object coordinates of the surface hit point on the associated geometry. If the given hit point is within the attached volume, the volume is sampled and classified with the transfer function attached to the volume. This implements the ability to visualize volume values (as colored by a transfer function) on arbitrary surfaces inside the volume (as opposed to an isosurface showing a particular value in the volume). Its parameters are as follows Type Name Description ------------------- ---------------- ----------------------------------------- OSPVolume volume [Volume] used to generate color lookups OSPTransferFunction transferFunction [transfer function] applied to `volume` ------------------- ---------------- ----------------------------------------- : Parameters of `volume` texture type. TextureVolume can be used for implementing slicing of volumes with any geometry type. It enables coloring of the slicing geometry with a different transfer function than that of the sliced volume. ### Texture Transformations All materials with textures also offer to manipulate the placement of these textures with the help of texture transformations. If so, this convention shall be used: the following parameters are prefixed with "`texture_name.*`"). Type Name Description --------- ------------ ------------------------------------------------- linear2f transform linear transformation (rotation, scale) float rotation angle in degree, counterclockwise, around center vec2f scale enlarge texture, relative to center $(0.5, 0.5)$ vec2f translation move texture in positive direction (right/up) --------- ------------ ------------------------------------------------- : Parameters to define 2D texture coordinate transformations. Above parameters are combined into a single `affine2d` transformation matrix and the transformations are applied in the given order. Rotation, scale and translation are interpreted "texture centric", i.e., their effect seen by an user are relative to the texture (although the transformations are applied to the texture coordinates). Type Name Description -------- ------------ -------------------------------------------------------- affine3f transform linear transformation (rotation, scale) plus translation -------- ------------ -------------------------------------------------------- : Parameter to define 3D volume texture transformations. Similarly, volume texture placement can also be modified by an `affine3f` transformation matrix. Cameras ------- To create a new camera of given type `type` use OSPCamera ospNewCamera(const char *type); All cameras accept these parameters: ----------- ----------------------- --------------------- ------------------------------------------ Type Name Default Description ----------- ----------------------- --------------------- ------------------------------------------ vec3f position $(0, 0, 0)$ position of the camera vec3f direction $(0, 0, 1)$ main viewing direction of the camera vec3f up $(0, 1, 0)$ up direction of the camera affine3f transform identity additional world-space transform, overridden by `motion.*` arrays float nearClip 10^-6^ near clipping distance vec2f imageStart $(0, 0)$ start of image region (lower left corner) vec2f imageEnd $(1, 1)$ end of image region (upper right corner) affine3f[] motion.transform additional uniformly distributed world-space transforms vec3f[] motion.scale additional uniformly distributed world-space scale, overridden by `motion.transform` vec3f[] motion.pivot additional uniformly distributed world-space translation which is applied before `motion.rotation` (i.e., the rotation center), overridden by `motion.transform` quatf[] motion.rotation additional uniformly distributed world-space quaternion rotation, overridden by `motion.transform` vec3f[] motion.translation additional uniformly distributed world-space translation, overridden by `motion.transform` box1f time [0, 1] time associated with first and last key in `motion.*` arrays box1f shutter [0.5, 0.5] start and end of shutter time (for motion blur), in [0, 1] uint shutterType `OSP_SHUTTER_GLOBAL` `OSPShutterType` for motion blur, also allowed are: `OSP_SHUTTER_ROLLING_RIGHT` `OSP_SHUTTER_ROLLING_LEFT` `OSP_SHUTTER_ROLLING_DOWN` `OSP_SHUTTER_ROLLING_UP` float rollingShutterDuration 0 for a rolling shutter (see `shutterType`) the "open" time per line, in [0, `shutter`.upper-`shutter`.lower] ----------- ----------------------- --------------------- ------------------------------------------ : Parameters accepted by all cameras. The camera is placed and oriented in the world with `position`, `direction` and `up`. Additionally, an extra transformation `transform` can be specified, which will only be applied to 3D vectors (i.e., `position`, `direction` and `up`), but does *not* affect any sizes (e.g., `nearClip`, `apertureRadius`, or `height`). The same holds for the array of transformations `motion.transform` to achieve camera motion blur (in combination with `time` and `shutter`). OSPRay uses a right-handed coordinate system. The region of the camera sensor that is rendered to the image can be specified in normalized screen-space coordinates with `imageStart` (lower left corner) and `imageEnd` (upper right corner). This can be used, for example, to crop the image, to achieve asymmetrical view frusta, or to horizontally flip the image to view scenes which are specified in a left-handed coordinate system. Note that values outside the default range of [0–1] are valid, which is useful to easily realize overscan or film gate, or to emulate a shifted sensor. ### Perspective Camera The perspective camera implements a simple thin lens camera for perspective rendering, supporting optionally depth of field and stereo rendering (with the [path tracer]). It is created by passing the type string "`perspective`" to `ospNewCamera`. In addition to the [general parameters](#cameras) understood by all cameras the perspective camera supports the special parameters listed in the table below. ----- ----------------------- ----------------- ----------------------------------------- Type Name Default Description ----- ----------------------- ----------------- ----------------------------------------- float fovy 60 the field of view (angle in degree) of the frame's height float aspect 1 ratio of width by height of the frame (and image region) float apertureRadius 0 size of the aperture, controls the depth of field float focusDistance 1 distance at where the image is sharpest when depth of field is enabled bool architectural false vertical edges are projected to be parallel uint stereoMode `OSP_STEREO_NONE` `OSPStereoMode` for stereo rendering, also allowed are: `OSP_STEREO_LEFT` `OSP_STEREO_RIGHT` `OSP_STEREO_SIDE_BY_SIDE` `OSP_STEREO_TOP_BOTTOM` (left eye at top half) float interpupillaryDistance 0.0635 distance between left and right eye when stereo is enabled ----- ----------------------- ----------------- ----------------------------------------- : Additional parameters accepted by the perspective camera. Note that when computing the `aspect` ratio a potentially set image region (using `imageStart` & `imageEnd`) needs to be regarded as well. In architectural photography it is often desired for aesthetic reasons to display the vertical edges of buildings or walls vertically in the image as well, regardless of how the camera is tilted. Enabling the `architectural` mode achieves this by internally leveling the camera parallel to the ground (based on the `up` direction) and then shifting the lens such that the objects in direction `dir` are centered in the image. If finer control of the lens shift is needed use `imageStart` & `imageEnd`. Because the camera is now effectively leveled its image plane and thus the plane of focus is oriented parallel to the front of buildings, the whole façade appears sharp, as can be seen in the example images below. The resolution of the [framebuffer] is not altered by `imageStart`/`imageEnd`. ![Example image created with the perspective camera, featuring depth of field.][imgCameraPerspective] ![Enabling the `architectural` flag corrects the perspective projection distortion, resulting in parallel vertical edges.][imgCameraArchitectural] ![Example 3D stereo image using `stereoMode = OSP_STEREO_SIDE_BY_SIDE`.][imgCameraStereo] ### Orthographic Camera The orthographic camera implements a simple camera with orthographic projection, without support for depth. It is created by passing the type string "`orthographic`" to `ospNewCamera`. In addition to the [general parameters](#cameras) understood by all cameras the orthographic camera supports the following special parameters: Type Name Description ------ ------- ------------------------------------------------------------ float height size of the camera's image plane in y, in world coordinates float aspect ratio of width by height of the frame ------ ------- ------------------------------------------------------------ : Additional parameters accepted by the orthographic camera. For convenience the size of the camera sensor, and thus the extent of the scene that is captured in the image, can be controlled with the `height` parameter. The same effect can be achieved with `imageStart` and `imageEnd`, and both methods can be combined. In any case, the `aspect` ratio needs to be set accordingly to get an undistorted image. ![Example image created with the orthographic camera.][imgCameraOrthographic] ### Panoramic Camera The panoramic camera implements a simple camera with support for stereo rendering. It captures the complete surrounding with a latitude / longitude mapping and thus the rendered images should best have a ratio of 2:1. A panoramic camera is created by passing the type string "`panoramic`" to `ospNewCamera`. It is placed and oriented in the scene by using the [general parameters](#cameras) understood by all cameras. ----- ---------------------- ----------------------------------------- Type Name Description ----- ---------------------- ----------------------------------------- uint stereoMode `OSPStereoMode` for stereo rendering, possible values are: `OSP_STEREO_NONE` (default) `OSP_STEREO_LEFT` `OSP_STEREO_RIGHT` `OSP_STEREO_SIDE_BY_SIDE` `OSP_STEREO_TOP_BOTTOM` (left eye at top half) float interpupillaryDistance distance between left and right eye when stereo is enabled, default 0.0635 ----- ---------------------- ----------------------------------------- : Additional parameters accepted by the panoramic camera. ![Latitude / longitude map created with the panoramic camera.][imgCameraPanoramic] Scene Hierarchy --------------- ### Groups Groups in OSPRay represent collections of GeometricModels, VolumetricModels and Lights which share a common local-space coordinate system. To create a group call OSPGroup ospNewGroup(); Groups take arrays of geometric models, volumetric models, clipping geometric models and lights, but they are all optional. In other words, there is no need to create empty arrays if there are no geometries, volumes or lights in the group. By adding `OSPGeometricModel`s to the `clippingGeometry` array a clipping geometry feature is enabled. Geometries assigned to this parameter will be used as clipping geometries. Any supported geometry can be used for clipping^[including spheres, boxes, infinite planes, closed meshes, closed subdivisions and curves], the only requirement is that it has to distinctly partition space into clipping and non-clipping one. The use of clipping geometry that is not closed or infinite could result in rendering artifacts. User can decide which part of space is clipped by changing shading normals orientation with the `invertNormals` flag of the [GeometricModel]. All geometries and volumes assigned to `geometry` or `volume` will be clipped. All clipping geometries from all groups and [Instances] will be combined together – a union of these areas will be applied to all other objects in the [world]. -------------------- ---------------- ---------- -------------------------------------- Type Name Default Description -------------------- ---------------- ---------- -------------------------------------- OSPGeometricModel[] geometry NULL [data] array of [GeometricModels] OSPVolumetricModel[] volume NULL [data] array of [VolumetricModels] OSPGeometricModel[] clippingGeometry NULL [data] array of [GeometricModels] used for clipping OSPLight[] light NULL [data] array of [lights] bool dynamicScene false tell Embree to use faster BVH build (slower ray traversal), otherwise optimized for faster ray traversal (slightly slower BVH build) bool compactMode false tell Embree to use a more compact BVH in memory by trading ray traversal performance bool robustMode false tell Embree to enable more robust ray intersection code paths (slightly slower) -------------------- ---------------- ---------- --------------------------------------- : Parameters understood by groups. ### Instances Instances in OSPRay represent a single group's placement into the world via a transform. To create and instance call OSPInstance ospNewInstance(OSPGroup); The passed group can be `NULL` as long as the group to be instanced is passed as a parameter. If both a group is specified on object creation and as a parameter, the parameter value is used. If the parameter value is later removed, the group object passed on object creation is again used. ------------ ----------------- ---------- -------------------------------------------------------- Type Name Default Description ------------ ----------------- ---------- -------------------------------------------------------- OSPGroup group optional [group] object to be instanced affine3f transform identity world-space transform for all attached geometries and volumes, overridden by `motion.*` arrays affine3f[] motion.transform uniformly distributed world-space transforms vec3f[] motion.scale uniformly distributed world-space scale, overridden by `motion.transform` vec3f[] motion.pivot uniformly distributed world-space translation which is applied before `motion.rotation` (i.e., the rotation center), overridden by `motion.transform` quatf[] motion.rotation uniformly distributed world-space quaternion rotation, overridden by `motion.transform` vec3f[] motion.translation uniformly distributed world-space translation, overridden by `motion.transform` box1f time [0, 1] time associated with first and last key in `motion.*` arrays (for motion blur) uint32 id -1u optional user ID, for [framebuffer] channel `OSP_FB_ID_INSTANCE` ------------ ----------------- ---------- -------------------------------------------------------- : Parameters understood by instances. ### World Worlds are a container of scene data represented by [instances]. To create an (empty) world call OSPWorld ospNewWorld(); Objects are placed in the world through an array of instances. Similar to [groups], the array of instances is optional: there is no need to create empty arrays if there are no instances (though there will be nothing to render). Applications can query the world (axis-aligned) bounding box after the world has been committed. To get this information, call OSPBounds ospGetBounds(OSPObject); The result is returned in the provided `OSPBounds`^[`OSPBounds` has essentially the same layout as the `OSP_BOX3F` [`OSPDataType`][data].] struct: typedef struct { float lower[3]; float upper[3]; } OSPBounds; This call can also take `OSPGroup` and `OSPInstance` as well: all other object types will return an empty bounding box. Finally, Worlds can be configured with parameters for making various feature/performance trade-offs (similar to groups). ------------- ---------------- -------- ------------------------------------- Type Name Default Description ------------- ---------------- -------- ------------------------------------- OSPInstance[] instance NULL [data] array with handles of the [instances] OSPLight[] light NULL [data] array with handles of the [lights] bool dynamicScene false tell Embree to use faster BVH build (slower ray traversal), otherwise optimized for faster ray traversal (slightly slower BVH build) bool compactMode false tell Embree to use a more compact BVH in memory by trading ray traversal performance bool robustMode false tell Embree to enable more robust ray intersection code paths (slightly slower) ------------- ---------------- -------- ------------------------------------- : Parameters understood by worlds. Renderers --------- A renderer is the central object for rendering in OSPRay. Different renderers implement different features and support different materials. To create a new renderer of given type `type` use OSPRenderer ospNewRenderer(const char *type); General parameters of all renderers are -------------- ------------------ ----------------------- ----------------------------------------- Type Name Default Description -------------- ------------------ ----------------------- ----------------------------------------- int pixelSamples 1 samples per pixel, best results when a power of 2 int maxPathLength 20 maximum ray recursion depth float minContribution 0.001 sample contributions below this value will be neglected to speedup rendering float varianceThreshold 0 threshold for adaptive accumulation float / backgroundColor black, background color and alpha (linear vec3f / vec4f transparent A/RGB/RGBA), if no `map_backplate` is set OSPTexture map_backplate optional [texture] image used as background (use texture type `texture2d`) OSPTexture map_maxDepth optional screen-sized float [texture] with maximum far distance per pixel (use texture type `texture2d`) OSPMaterial[] material optional [data] array of [materials] which can be indexed by a [GeometricModel]'s `material` parameter uint pixelFilter `OSP_PIXELFILTER_GAUSS` `OSPPixelFilterType` to select the pixel filter used by the renderer for antialiasing. Possible pixel filters are listed below. float mipMapBias 0 bias for texture MIP-mapping, balancing between sharpness/aliasing and blurriness due to prefiltering -------------- ------------------ ----------------------- ----------------------------------------- : Parameters understood by all renderers. OSPRay's renderers support a feature called adaptive accumulation, which accelerates progressive [rendering] by stopping the rendering and refinement of image regions that have an estimated variance below the `varianceThreshold`. This feature requires a [framebuffer] with an `OSP_FB_VARIANCE` channel. Per default the background of the rendered image will be transparent black, i.e., the alpha channel holds the opacity of the rendered objects. This eases transparency-aware blending of the image with an arbitrary background image by the application (via $ospray.rgb + appBackground.rgbâ‹…(1-ospray.alpha)$). The parameter `backgroundColor` or `map_backplate` can be used to already blend with a constant background color or backplate texture, respectively, (and alpha) during rendering. OSPRay renderers support depth composition with images of other renderers, for example to incorporate help geometries of a 3D UI that were rendered with OpenGL. The screen-sized [texture] `map_maxDepth` must have format `OSP_TEXTURE_R32F` and flag `OSP_TEXTURE_FILTER_NEAREST`. The fetched values are used to limit the distance of primary rays, thus objects of other renderers can hide objects rendered by OSPRay. OSPRay supports antialiasing in image space by using pixel filters, which are aligned around the center of a pixel. The size $w×w$ of the filter depends on the selected filter type. The types of supported pixel filters are defined by the `OSPPixelFilterType` enum and can be set using the `pixelFilter` parameter. -------------------------------- --------------------------------------------- Name Description -------------------------------- --------------------------------------------- OSP_PIXELFILTER_POINT a point filter only samples the center of the pixel, therefore the filter width is $w = 0$ OSP_PIXELFILTER_BOX a uniform box filter with a width of $w = 1$ OSP_PIXELFILTER_GAUSS a truncated, smooth Gaussian filter with a standard deviation of $\sigma = 0.5$ and a filter width of $w = 3$ OSP_PIXELFILTER_MITCHELL the Mitchell-Netravali filter with a width of $w = 4$ OSP_PIXELFILTER_BLACKMAN_HARRIS the Blackman-Harris filter with a width of $w = 3$ -------------------------------- --------------------------------------------- : Pixel filter types supported by OSPRay for antialiasing in image space. OSPRay also antialiases textures with prefiltering and MIP-mapping, which can be adjusted with parameter `mipMapBias`. For final frame rendering with a high number of `pixelSamples` or accumulated frames `mipMapBias` can be lowered (e.g., set to -0.5 or -2) to result in sharper textures which are essentially anisotropically filtered. Conversely, for preview rendering with just a single sample per pixel a higher `mipMapBias` of 1 or 2 can reduce texture aliasing and increase rendering speed. ### SciVis Renderer The SciVis renderer is a fast ray tracer for scientific visualization which supports volume rendering and ambient occlusion (AO). It is created by passing the type string "`scivis`" to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers, the SciVis renderer supports the following parameters: ------ ------------------- --------- ---------------------------------- Type Name Default Description ------ ------------------- --------- ---------------------------------- bool shadows false whether to compute (hard) shadows int aoSamples 0 number of rays per sample to compute ambient occlusion float aoDistance 10^20^ maximum distance to consider for ambient occlusion float volumeSamplingRate 1 sampling rate for volumes bool visibleLights false whether light sources are potentially visible (as in the [path tracer], regarding each light's `visible`) ------ ------------------- --------- ---------------------------------- : Special parameters understood by the SciVis renderer. Note that the intensity (and color) of AO is deduced from an [ambient light] in the `lights` array.^[If there are multiple ambient lights then their contribution is added.] If `aoSamples` is zero (the default) then ambient lights cause ambient illumination (without occlusion). ### Ambient Occlusion Renderer This renderer supports only a subset of the features of the [SciVis renderer] to gain performance. As the name suggest its main shading method is ambient occlusion (AO), [lights] are *not* considered at all. Volume rendering is supported. The Ambient Occlusion renderer is created by passing the type string "`ao`" to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers the following parameters are supported as well: ------------- ---------------------- ------------ ---------------------------- Type Name Default Description ------------- ---------------------- ------------ ---------------------------- int aoSamples 1 number of rays per sample to compute ambient occlusion float aoDistance 10^20^ maximum distance to consider for ambient occlusion float aoIntensity 1 ambient occlusion strength float volumeSamplingRate 1 sampling rate for volumes ------------- ---------------------- ------------ ---------------------------- : Special parameters understood by the Ambient Occlusion renderer. ### Path Tracer The path tracer supports soft shadows, indirect illumination and realistic materials. This renderer is created by passing the type string "`pathtracer`" to `ospNewRenderer`. In addition to the [general parameters](#renderer) understood by all renderers the path tracer supports the following special parameters: ------ -------------------------- -------- ---------------------------------- Type Name Default Description ------ -------------------------- -------- ---------------------------------- int lightSamples all number of random light samples per path vertex, best results when a power of 2; per default all light sources are sampled bool limitIndirectLightSamples true after the first non-specular (i.e., diffuse and glossy) path vertex take (at most) a single light sample (instead of `lightSamples` many) int roulettePathLength 5 ray recursion depth at which to start Russian roulette termination int maxScatteringEvents 20 maximum number of non-specular (i.e., diffuse and glossy) bounces float maxContribution ∞ samples are clamped to this value before they are accumulated into the framebuffer bool backgroundRefraction false allow for alpha blending even if background is seen through refractive objects like glass ------ -------------------------- -------- ---------------------------------- : Special parameters understood by the path tracer. The path tracer requires that [materials] are assigned to [geometries], otherwise surfaces are treated as completely black. The path tracer supports [volumes](#volumes) with multiple scattering. The scattering albedo can be specified using the [transfer function]. Extinction is assumed to be spectrally constant. Framebuffer ----------- The framebuffer holds the rendered 2D image (and optionally auxiliary information associated with pixels). To create a new framebuffer object of given size `size` (in pixels), color format, and channels use OSPFrameBuffer ospNewFrameBuffer(int size_x, int size_y, OSPFrameBufferFormat format = OSP_FB_SRGBA, uint32_t frameBufferChannels = OSP_FB_COLOR); The parameter `format` describes the format the color buffer has _on the host_, and the format that `ospMapFrameBuffer` will eventually return. Valid values are: Name Description --------------- ------------------------------------------------------------- OSP_FB_NONE framebuffer will not be mapped by the application OSP_FB_RGBA8 8\ bit [0–255] linear component red, green, blue, alpha OSP_FB_SRGBA 8\ bit sRGB gamma encoded color components, and linear alpha OSP_FB_RGBA32F 32\ bit float components red, green, blue, alpha --------------- ------------------------------------------------------------- : Supported color formats of the framebuffer that can be passed to `ospNewFrameBuffer`, i.e., valid constants of type `OSPFrameBufferFormat`. The parameter `frameBufferChannels` specifies which channels the framebuffer holds, and can be combined together by bitwise OR from the values of `OSPFrameBufferChannel` listed in the table below. Name Description ------------------- ---------------------------------------------------------- OSP_FB_COLOR RGB color including alpha OSP_FB_DEPTH euclidean distance to the camera (_not_ to the image plane), as linear 32\ bit float; for multiple samples per pixel their minimum is taken OSP_FB_ACCUM accumulation buffer for progressive refinement OSP_FB_VARIANCE for estimation of the current noise level if OSP_FB_ACCUM is also present, see [rendering] OSP_FB_NORMAL accumulated world-space normal of the first non-specular hit, as vec3f OSP_FB_ALBEDO accumulated material albedo (color without illumination) at the first non-specular hit, as vec3f OSP_FB_ID_PRIMITIVE primitive index of the first hit, as uint32 OSP_FB_ID_OBJECT geometric/volumetric model `id`, if specified, or index in [group] of first hit, as uint32 OSP_FB_ID_INSTANCE user defined [instance] `id`, if specified, or instance index of first hit, as uint32 ------------------- ---------------------------------------------------------- : Framebuffer channels constants (of type `OSPFrameBufferChannel`), naming optional information the framebuffer can store. These values can be combined by bitwise OR when passed to `ospNewFrameBuffer`. If a certain channel value is _not_ specified, the given buffer channel will not be present. Note that OSPRay makes a clear distinction between the _external_ format of the framebuffer and the internal one: The external format is the format the user specifies in the `format` parameter; it specifies what color format OSPRay will eventually _return_ the framebuffer to the application (when calling `ospMapFrameBuffer`): no matter what OSPRay uses internally, it will simply return a 2D array of pixels of that format, with possibly all kinds of reformatting, compression/decompression, etc., going on in-between the generation of the _internal_ framebuffer and the mapping of the externally visible one. In particular, `OSP_FB_NONE` is a perfectly valid pixel format for a framebuffer that an application will never map. For example, an application driving a display wall may well generate an intermediate framebuffer and eventually transfer its pixel to the individual displays using an `OSPImageOperation` [image operation]. The application can map the given channel of a framebuffer – and thus access the stored pixel information – via const void *ospMapFrameBuffer(OSPFrameBuffer, OSPFrameBufferChannel = OSP_FB_COLOR); Note that `OSP_FB_ACCUM` or `OSP_FB_VARIANCE` cannot be mapped. The origin of the screen coordinate system in OSPRay is the lower left corner (as in OpenGL), thus the first pixel addressed by the returned pointer is the lower left pixel of the image. A previously mapped channel of a framebuffer can be unmapped by passing the received pointer `mapped` to void ospUnmapFrameBuffer(const void *mapped, OSPFrameBuffer); The individual channels of a framebuffer can be cleared with void ospResetAccumulation(OSPFrameBuffer); This function will clear *all* accumulating buffers (`OSP_FB_VARIANCE`, `OSP_FB_NORMAL`, and `OSP_FB_ALBEDO`, if present) and resets the accumulation counter `accumID`. It is unspecified if the existing color and depth buffers are physically cleared when `ospResetAccumulation` is called. If `OSP_FB_VARIANCE` is specified, an estimate of the variance of the last accumulated frame can be queried with float ospGetVariance(OSPFrameBuffer); Note this value is only updated after synchronizing with `OSP_FRAME_FINISHED`, as further described in [asynchronous rendering]. The estimated variance can be used by the application as a quality indicator and thus to decide whether to stop or to continue progressive rendering. The framebuffer takes a list of pixel operations to be applied to the image in sequence as an `OSPData`. The pixel operations will be run in the order they are in the array. -------------------- --------------- ----------------------------------------- Type Name Description -------------------- --------------- ----------------------------------------- OSPImageOperation[] imageOperation ordered sequence of image operations int targetFrames anticipated number of frames that will be accumulated for progressive refinement, used renderers to generate a blue noise sampling pattern; should be a power of 2, is always 1 without `OSP_FB_ACCUM`; default 0 (disabled) -------------------- --------------- ----------------------------------------- : Parameters accepted by the framebuffer. If the total number of frames to be accumulated is known, then `targetFrames` should be set, because then renderers can generate more pleasing blue noise patterns. Accumulation stops when `targetFrames` is reached. ### Image Operation Image operations are functions that are applied to every pixel of a frame. Examples include post-processing, filtering, blending, tone mapping, or sending tiles to a display wall. To create a new pixel operation of given type `type` use OSPImageOperation ospNewImageOperation(const char *type); #### Tone Mapper The tone mapper is a pixel operation which implements a generic filmic tone mapping operator. Using the default parameters it approximates the Academy Color Encoding System (ACES). The tone mapper is created by passing the type string "`tonemapper`" to `ospNewImageOperation`. The tone mapping curve can be customized using the parameters listed in the table below. ------ ---------- --------- --------- ----------------------------------------- Type Name Default Filmic Description ------ ---------- --------- --------- ----------------------------------------- float exposure 1.0 1.0 amount of light per unit area float contrast 1.6773 1.1759 contrast (toe of the curve); typically is in [1–2] float shoulder 0.9714 0.9746 highlight compression (shoulder of the curve); typically is in [0.9–1] float midIn 0.18 0.18 mid-level anchor input; default is 18% gray float midOut 0.18 0.18 mid-level anchor output; default is 18% gray float hdrMax 11.0785 6.3704 maximum HDR input that is not clipped bool acesColor true false apply the ACES color transforms ------ ---------- --------- --------- ----------------------------------------- : Parameters accepted by the tone mapper. The column "Filmic" lists alternative values for the popular "Uncharted 2" tone mapping curve (note that that curve includes an exposure bias to match 18% middle gray). #### Denoiser OSPRay comes with a module that adds support for Intel® Open Image Denoise (OIDN). This is provided as an optional module as it creates an additional project dependency at compile time. The module implements a "`denoiser`" frame operation, which denoises the entire frame before the frame is completed. OIDN will automatically select the fastest device, using a GPU when available. The device selection be overridden by the environment variable `OIDN_DEFAULT_DEVICE`, possible values are `cpu`, `sycl`, `cuda`, `hip`, or a physical device ID ----- ------------- ---------------------------------------------------------- Type Name Description ----- ------------- ---------------------------------------------------------- uint quality `OSPDenoiserQuality` for denoiser quality, default is `OSP_DENOISER_QUALITY_MEDIUM`: balanced quality/performance for interactive/real-time rendering; also allowed are: `OSP_DENOISER_QUALITY_LOW`: high performance, for interactive/real-time preview rendering `OSP_DENOISER_QUALITY_HIGH`: high quality, for final frame rendering bool denoiseAlpha whether to denoise the alpha channel as well, default false ----- ------------- ---------------------------------------------------------- : Parameters accepted by the denoiser. Rendering --------- ### Asynchronous Rendering Rendering is by default asynchronous (non-blocking), and is done by combining a framebuffer, renderer, camera, and world. What to render and how to render it depends on the renderer's parameters. If the framebuffer supports accumulation (i.e., it was created with `OSP_FB_ACCUM`) then successive calls to `ospRenderFrame` will progressively refine the rendered image (until `targetFrames` is reached). To start an render task, use OSPFuture ospRenderFrame(OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld); This returns an `OSPFuture` handle, which can be used to synchronize with the application, cancel, or query for progress of the running task. When `ospRenderFrame` is called, there is no guarantee when the associated task will begin execution. Progress of a running frame can be queried with the following API function float ospGetProgress(OSPFuture); This returns the approximated progress of the task in [0-1]. Applications can cancel a currently running asynchronous operation via void ospCancel(OSPFuture); Applications can wait on the result of an asynchronous operation, or choose to only synchronize with a specific event. To synchronize with an `OSPFuture` use void ospWait(OSPFuture, OSPSyncEvent = OSP_TASK_FINISHED); The following are values which can be synchronized with the application -------------------- -------------------------------------------------------- Name Description -------------------- -------------------------------------------------------- OSP_NONE_FINISHED Do not wait for anything to be finished (immediately return from `ospWait`) OSP_WORLD_COMMITTED Wait for the world to be committed (not yet implemented) OSP_WORLD_RENDERED Wait for the world to be rendered, but not post-processing operations (Pixel/Tile/Frame Op) OSP_FRAME_FINISHED Wait for all rendering operations to complete OSP_TASK_FINISHED Wait on full completion of the task associated with the future. The underlying task may involve one or more of the above synchronization events -------------------- -------------------------------------------------------- : Supported events that can be passed to `ospWait`. Currently only rendering can be invoked asynchronously. However, future releases of OSPRay may add more asynchronous versions of API calls (and thus return `OSPFuture`). Applications can query whether particular events are complete with int ospIsReady(OSPFuture, OSPSyncEvent = OSP_TASK_FINISHED); As the given running task runs (as tracked by the `OSPFuture`), applications can query a boolean [0, 1] result if the passed event has been completed. Applications can query how long an async task ran with float ospGetTaskDuration(OSPFuture); This returns the wall clock execution time of the task in seconds. If the task is still running, this will block until the task is completed. This is useful for applications to query exactly how long an asynchronous task executed without the overhead of measuring both task execution + synchronization by the calling application. ### Synchronous Rendering For convenience in certain use cases, `ospray_util.h` provides a synchronous version of `ospRenderFrame`: float ospRenderFrameBlocking(OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld); This version is the equivalent of: ospRenderFrame ospWait(f, OSP_TASK_FINISHED) return ospGetVariance(fb) This version is closest to `ospRenderFrame` from OSPRay v1.x. ### Rendering and ospCommit The use of either `ospRenderFrame` or `ospRenderFrameBlocking` requires that all objects in the scene being rendered have been committed before rendering occurs. If a call to `ospCommit` happens while a frame is rendered, the result is undefined behavior and should be avoided. ### Picking To get the world-space position of the geometry (if any) seen at [0–1] normalized screen-space pixel coordinates `screenPos_x` and `screenPos_y` use void ospPick(OSPPickResult *, OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld, float screenPos_x, float screenPos_y); The result is returned in the provided `OSPPickResult` struct: typedef struct { int hasHit; float worldPosition[3]; OSPInstance instance; OSPGeometricModel model; uint32_t primID; } OSPPickResult; Note that `ospPick` considers exactly the same camera of the given renderer that is used to render an image, thus matching results can be expected. If the camera supports depth of field then the center of the lens and thus the center of the circle of confusion is used for picking. Note that the caller needs to `ospRelease` the `instance` and `model` handles of `OSPPickResult` once the information is not needed anymore. Modules and Devices =================== CPU ---- The CPU module is implicitly loaded and the `cpu` device is automatically used if no other options are specified. GPU (Beta) --------- To use the GPU for rendering load the `gpu` module and select the `gpu` device: ```sh ./ospExamples --osp:load-modules=gpu --osp:device=gpu ``` or via explicit device creation by the application: ospLoadModule("gpu"); OSPDevice dev = ospNewDevice("gpu"); ospDeviceCommit(dev); ospSetCurrentDevice(dev); Type Name Description -------- ------------- -------------------------------- void\ * syclContext SYCL context void\ * syclDevice SYCL device -------- ------------- -------------------------------- : Parameters specific to the `gpu` device. Applications can set their SYCL context and device to share device memory with OSPRay or to control which device should be used (e.g., in case multiple GPUs are present). If neither parameter is set, the `gpu` device will automatically create a context internally and select a GPU (that selection can be influenced via environment variable `ONEAPI_DEVICE_SELECTOR`, see [Intel oneAPI DPC++ Compiler documentation](https://intel.github.io/llvm-docs/EnvironmentVariables.html#oneapi-device-selector)). Compile times for just in time compilation (JIT compilation) can be large. To resolve this issue we recommend enabling persistent JIT compilation caching inside your application before the SYCL device is created, by setting environment variables `SYCL_CACHE_PERSISTENT=1` (and optionally `SYCL_CACHE_DIR=` to some proper directory where the JIT cache should get stored). To reduce GPU memory allocation overhead when rendering scenes with many objects (geometries, instances, etc.), memory pooling should be enabled by setting the environment variable `SYCL_PI_LEVEL_ZERO_USM_ALLOCATOR="1;0;shared:1M,0,2M"`. See [Intel oneAPI DPC++ Compiler documentation](https://intel.github.io/llvm-docs/EnvironmentVariables.html#debugging-variables-for-level-zero-plugin) for more details. ### Known Issues {-} The following features are not implemented yet or are not working correctly on the GPU device: - Multiple volumes in the scene - Clipping - Motion blur - Subdivision surfaces - Progress reporting via `ospGetProgress` or canceling the frame via `ospCancel` - Picking via `ospPick` - Adaptive accumulation via `OSP_FB_VARIANCE` and `varianceThreshold` - Framebuffer channels `OSP_FB_ID_*` (id buffers) - Experimental support for shared device-only data, works only for `structuredRegular` volume There will be some delay on start-up as the kernel code is JIT compiled for the device, and similar pauses when changing the scene configuration, because the kernel specialized and re-compiled. For some combination of compiler, GPU driver and scene the rendered images might show artifacts (e.g., vertical lines or small blocks). Distributed Rendering with MPI ------------------------------ The purpose of OSPRay's MPI modules is to provide distributed rendering capabilities for OSPRay. The modules enables image- and data-parallel rendering across HPC clusters using MPI, allowing applications to transparently distribute rendering work, or to render data sets which are too large to fit in memory on a single machine. OSPRay provides multiple MPI modules that expose different distributed rendering capabilities. The `mpi_offload` module provides image-parallel rendering through the `mpiOffload` device; it enables OSPRay applications written for local rendering to be replicated across multiple nodes to distribute the rendering work without code changes. And the `mpi_distributed_cpu` and `mpi_distributed_gpu` modules provides data-parallel rendering through the `mpiDistributed` device, which allows MPI distributed applications to use OSPRay for distributed rendering. Each rank using the `mpiDistributed` device can render an independent piece of a global data set, or perform hybrid rendering where ranks partially or completely share data. The `mpiDistributed` device's image-parallel rendering support can be used to accelerate data loading for image-parallel applications, where all ranks load the same data from a shared disk and then perform image-parallel rendering on the replicated data, as if the `mpiOffload` device where being used. ### MPI Offload Rendering The `mpiOffload` device can be used to distribute image rendering tasks across a cluster without requiring modifications to the application itself. Existing applications using OSPRay for local rendering simply be passed command line arguments to load the module and indicate that the `mpiOffload` device should be used for image-parallel rendering. To load the module, pass `--osp:load-modules=mpi_offload`, to select the MPIOffloadDevice, pass `--osp:device=mpiOffload`. For example, the `ospExamples` application can be run as: ```sh mpirun -n ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload ``` and will automatically distribute the image rendering tasks among the corresponding `N` nodes. Note that in this configuration rank 0 will act as a master/application rank, and will run the user application code but not perform rendering locally. Thus, a minimum of 2 ranks are required, one master to run the application and one worker to perform the rendering. Running with 3 ranks for example would now distribute half the image rendering work to rank 1 and half to rank 2. If more control is required over the placement of ranks to nodes, or you want to run a worker rank on the master node as well you can run the application and the `ospray_mpi_worker` program through MPI's MPMD mode. The `ospray_mpi_worker` will load the MPI module and select the offload device by default. ```sh mpirun -n 1 ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload \ : -n ./ospray_mpi_worker ``` If initializing the `mpiOffload` device manually, or passing parameters through the command line, the following parameters can be set: -------- ------------------------ --------- --------------------------------- Type Name Default Description -------- ------------------------ --------- --------------------------------- string mpiMode mpi The mode to communicate with the worker ranks. `mpi` will assume you are launching the application and workers in the same mpi command (or split launch command). `mpi` is the only supported mode uint maxCommandBufferEntries 8192 Set the max number of commands to buffer before submitting the command buffer to the workers uint commandBufferSize 512\ MiB Set the max command buffer size to allow. Units are in MiB. Max size is 1.8\ GiB uint maxInlineDataSize 32\ MiB Set the max size of an OSPData which can be inline'd into the command buffer instead of being sent separately. Max size is half the commandBufferSize. Units are in MiB -------- ------------------------ --------- --------------------------------- : Parameters specific to the `mpiOffload` device. The `maxCommandBufferEntries`, `commandBufferSize`, and `maxInlineDataSize` can also be set via the environment variables: `OSPRAY_MPI_MAX_COMMAND_BUFFER_ENTRIES`, `OSPRAY_MPI_COMMAND_BUFFER_SIZE`, and `OSPRAY_MPI_MAX_INLINE_DATA_SIZE`, respectively. The `mpiOffload` device uses a dynamic load balancer by default. If you wish to use a static load balancer you can do so by setting the `OSPRAY_STATIC_BALANCER` environment variable to 1. For the worker ranks to create GPU devices instead of the default CPU devices set the environment variable `OSPRAY_MPI_DISTRIBUTED_GPU`, e.g., ```sh export OSPRAY_MPI_DISTRIBUTED_GPU=1 ``` or ```sh mpiexec -genv OSPRAY_MPI_DISTRIBUTED_GPU 1 \ -n 1 ./ospExamples --osp:load-modules=mpi_offload --osp:device=mpiOffload \ : -n 2 ./ospray_mpi_worker ``` The `mpiOffload` device does not support multiple init/shutdown cycles. Thus, to run `ospBenchmark` for this device make sure to exclude the init/shutdown test by passing `--benchmark_filter=-ospInit_ospShutdown` through the command line. ### MPI Distributed Rendering While MPI Offload rendering is used to transparently distribute rendering work without requiring modification to the application, MPI Distributed rendering is targeted at use of OSPRay within MPI-parallel applications. The MPI distributed device can be selected by loading the `mpi_distributed_cpu` module for CPU rendering or `mpi_distributed_gpu` for GPU rendering, and manually creating and using an instance of the `mpiDistributed` device, for example: ospLoadModule("mpi_distributed_cpu"); OSPDevice mpiDevice = ospNewDevice("mpiDistributed"); ospDeviceCommit(mpiDevice); ospSetCurrentDevice(mpiDevice); Your application can either initialize MPI before-hand, ensuring that `MPI_THREAD_SERIALIZED` or higher is supported, or allow the device to initialize MPI on commit. Thread multiple support is required if your application will make MPI calls while rendering asynchronously with OSPRay. When using the distributed device each rank can specify independent local data using the OSPRay API, as if rendering locally. However, when calling `ospRenderFrameAsync` the ranks will work collectively to render the data. The distributed device supports both image-parallel, where the data is replicated, and data-parallel, where the data is distributed, rendering modes. The `mpiDistributed` device will by default use each rank in `MPI_COMM_WORLD` as a render worker; however, it can also take a specific MPI communicator to use as the world communicator. Only those ranks in the specified communicator will participate in rendering. -------- ------------------ ---------------- -------------------------------- Type Name Default Description -------- ------------------ ---------------- -------------------------------- void\ * worldCommunicator MPI_COMM_WORLD The MPI communicator which the OSPRay workers should treat as their world -------- ------------------ ---------------- -------------------------------- : Parameters specific to the `mpiDistributed` device. -------- ------- --------- ----------------------------------------------- Type Name Default Description -------- ------- --------- ----------------------------------------------- box3f[] region NULL A list of bounding boxes which bound the owned local data to be rendered by the rank -------- ------- --------- ----------------------------------------------- : Parameters specific to the distributed `OSPWorld`. ------ ------------------- --------- ------------------------------------------------ Type Name Default Description ------ ------------------- --------- ------------------------------------------------ int aoSamples 0 The number of AO samples to take per-pixel float aoDistance 10^20^ The AO ray length to use. Note that if the AO ray would have crossed a rank boundary and ghost geometry is not available, there will be visible artifacts in the shading float volumeSamplingRate 1 sampling rate for volumes ------ ------------------- --------- ------------------------------------------------ : Parameters specific to the `mpiRaycast` renderer. #### Image Parallel Rendering in the MPI Distributed Device If all ranks specify exactly the same data, the distributed device can be used for image-parallel rendering. This works identical to the offload device, except that the MPI-aware application is able to load data in parallel on each rank rather than loading on the master and shipping data out to the workers. When a parallel file system is available, this can improve data load times. Image-parallel rendering is selected by specifying the same data on each rank, and using any of the existing local renderers (e.g., `scivis`, `pathtracer`). See [ospMPIDistribTutorialReplicated](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialReplicated.cpp) for an example. #### Data Parallel Rendering in the MPI Distributed Device The MPI Distributed device also supports data-parallel rendering with sort-last compositing. Each rank can specify a different piece of data, as long as the bounding boxes of each rank's data are non-overlapping. The rest of the scene setup is similar to local rendering; however, for distributed rendering only the `mpiRaycast` renderer is supported. This renderer implements a subset of the `scivis` rendering features which are suitable for implementation in a distributed environment. By default the aggregate bounding box of the instances in the local world will be used as the bounds of that rank's data. However, when using ghost zones for volume interpolation, geometry or ambient occlusion, each rank's data can overlap. To clip these non-owned overlap regions out a set of regions (the `region` parameter) can pass as a parameter to the `OSPWorld` being rendered. Each rank can specify one or more non-overlapping `box3f`'s which bound the portions of its local data which it is responsible for rendering. See the [ospMPIDistribTutorialVolume](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialVolume.cpp) for an example. Finally, the MPI distributed device also supports hybrid-parallel rendering, where multiple ranks can share a single piece of data. For each shared piece of data the rendering work will be assigned image-parallel among the ranks. Partially-shared regions are determined by finding those ranks specifying data with the same bounds (matching regions) and merging them. See the [ospMPIDistribTutorialPartialRepl](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorialPartialRepl.cpp) for an example. #### Picking on Distributed Data in the MPI Distributed Device {-} Calling `ospPick` in the distributed device will find and return the closest global object at the screen position on the rank that owns that object. The other ranks will report no hit. Picking in the distributed device takes into account data clipping applied through the `regions` parameter to avoid picking ghost data. ### Interaction with User Modules The MPI Offload rendering mode trivially supports user modules, with the caveat that attempting to share data directly with the application (e.g., passing a `void *` or other tricks to the module) will not work in a distributed environment. Instead, use the `ospNewSharedData` API to share data from the application with OSPRay, which will in turn be copied over the network to the workers. The MPI Distributed device also supports user modules, as all that is required for compositing the distributed data are the bounds of each rank's local data. MultiDevice ----------- The multidevice module is an experimental OSPRay device type that renders images by delegating off pixel tiles to a number of internal delegate OSPRay devices. If you wish to try it set the `OSPRAY_NUM_SUBDEVICES` environmental variable to the number of subdevices you want to create and tell OSPRay to both load the `multidevice_cpu` extension and create a multidevice for rendering instead of the default CPU device. One example in a bash like shell is as follows: ```sh OSPRAY_NUM_SUBDEVICES=6 ./ospTutorial --osp:load-modules=multidevice_cpu --osp:device=multidevice ``` Note that the multidevice currently does not support `OSPImageOperation`s for denoising nor tone mapping.

Should you want to specify a different compiler, run cmake manually while specifying the desired compiler. The default compiler on most linux machines is `gcc`, but it can be pointed to `clang` instead by executing the following: cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang .. CMake will now use Clang instead of GCC. If you are OK with using the default compiler on your system, then simply skip this step. Note that the compiler variables cannot be changed after the first `cmake` or `ccmake` run. - Open the CMake configuration dialog ccmake .. - Make sure to properly set build mode and enable the components you need, etc.; then type 'c'onfigure and 'g'enerate. When back on the command prompt, build it using make - You should now have `libospray.[so,dylib]` as well as a set of [example applications]. ### Compiling OSPRay on Windows On Windows using the CMake GUI (`cmake-gui.exe`) is the most convenient way to configure OSPRay and to create the Visual Studio solution files: - Browse to the OSPRay sources and specify a build directory (if it does not exist yet CMake will create it). - Click "Configure" and select as generator the Visual Studio version you have; OSPRay needs "Visual Studio 15 2017 Win64" or newer, 32\ bit builds are not supported, e.g., "Visual Studio 17 2022". - If the configuration fails because some dependencies could not be found then follow the instructions given in the error message, e.g., set the variable `embree_DIR` to the folder where Embree was installed and `openvkl_DIR` to where Open VKL was installed. - Optionally change the default build options, and then click "Generate" to create the solution and project files in the build directory. - Open the generated `OSPRay.sln` in Visual Studio, select the build configuration and compile the project. Alternatively, OSPRay can also be built without any GUI, entirely on the console. In the Visual Studio command prompt type: cd path\to\ospray mkdir build cd build cmake -G "Visual Studio 17 2022" [-D VARIABLE=value] .. cmake --build . --config Release Use `-D` to set variables for CMake, e.g., the path to Embree with "`-D embree_DIR=\path\to\embree`". You can also build only some projects with the `--target` switch. Additional parameters after "`--`" will be passed to `msbuild`. For example, to build in parallel only the OSPRay library without the example applications use cmake --build . --config Release --target ospray -- /m Finding an OSPRay Install with CMake ------------------------------------ Client applications using OSPRay can find it with CMake's `find_package()` command. For example, find_package(ospray 3.0.0 REQUIRED) finds OSPRay via OSPRay's configuration file `osprayConfig.cmake`^[This file is usually in `${install_location}/[lib|lib64]/cmake/ospray-${version}/`. If CMake does not find it automatically, then specify its location in variable `ospray_DIR` (either an environment variable or CMake variable).]. Once found, the following is all that is required to use OSPRay: target_link_libraries(${client_target} ospray::ospray) This will automatically propagate all required include paths, linked libraries, and compiler definitions to the client CMake target (either an executable or library). Advanced users may want to link to additional targets which are exported in OSPRay's CMake config, which includes all installed modules. All targets built with OSPRay are exported in the `ospray::` namespace, therefore all targets locally used in the OSPRay source tree can be accessed from an install. For example, `ospray_module_cpu` can be consumed directly via the `ospray::ospray_module_cpu` target. All targets have their libraries, includes, and definitions attached to them for public consumption (please [report bugs] if this is broken!).

This guide is intended as an introduction to the new features and the concepts behind them, and as a guide to porting applications using OSPRay v1.8.x to v2.0.0. Parameters ---------- ### Setting parameters OSPRay traded having a limited number of parameter types (with a unique function signature for each type) by instead having a single generic function that takes any type found in the `OSPDataType` enum. The new function signature is as follows: void ospSetParam(OSPObject, const char *name, OSPDataType type, const void *mem) This function takes the address of the value being set, where care should be taken when setting pointer-based types. For example, consider the following C-array: float myValues[] = {0.f, 1.f, 2.f} If the application wants to set these values as an OSP_VEC3F, note that the `const void *mem` parameter to `ospSetParam` should point to what is the address of what would be a `vec3f`. Thus either of the following are valid: void ospSetParam(object, "some_parameter", OSP_VEC3F, &myValues[0]); or void ospSetParam(object, "some_parameter", OSP_VEC3F, myValues); The second variant relies on implicit casting from `float[]` to `float *`, which will point to the address of the first value. This then gets casted to a `vec3f` to be set on the target `object`. Some of the `ospSet*` functions were preserved as utility wrapper functions outlined later in this document (and can be found in `ospray_util.h`). ### OSPDataType type checking Where it was previously accepted to create data of generic type `OSP_OBJECT` to represent a list of any object type, the `OSPDataType` must now match the object(s) it contains. Objects ------- ### New Object Hierarchy OSPRay objects, such as `OSPGeometry` and `OSPVolume`, have a new hierarchy that affords more control over geometry and volume transformation and instancing in the scene. Previously, the workflow was to create an object, fill it with the necessary parameters, and then place the object into an `OSPModel` via, for example, `ospAddGeometry`. An example is shown below using the C API. OSPGeometry mesh = ospNewGeometry("triangles"); // set parameters on mesh ospCommit(mesh); OSPModel world = ospNewModel(); ospAddGeometry(world, mesh); ospRelease(mesh); ospCommit(world); In OSPRay v2.0.0, there is now an `OSPWorld`, which effectively replaces the old `OSPModel`. In addition, there are now 3 new objects that exist "in between" the geometry and the world: `OSPGeometricModel`, `OSPGroup`, and `OSPInstance`. There is also an `OSPVolumetricModel` equivalent for working with `OSPVolume` objects. The new workflow is shown below. Note that calls to `ospRelease()` have been removed for brevity. // create a geometry OSPGeometry mesh = ospNewGeometry("triangles"); // set parameters on mesh ospCommit(mesh); // put the geometry in a model (a geometry can exist in more than one model) OSPGeometricModel model = ospNewGeometricModel(mesh); ospCommit(model); // put the geometric model(s) in a group OSPGroup group = ospNewGroup(); OSPData geometricModels = ospNewSharedData1D(&model, OSP_GEOMETRIC_MODEL, 1); ospSetObject(group, "geometry", geometricModels); ospCommit(group); // put the group in an instance (a group can be instanced more than once) OSPInstance = ospNewInstance(group); ospCommit(instance); // put the instance in the world OSPWorld world = ospNewWorld(); OSPData instances = ospNewSharedData1D(&instance, OSP_INSTANCE, 1); ospSetObject(world, "instance", instances); ospCommit(world); While this looks more complex at first, the new hierarchy structure provides more fine control over appearance information and instance transformations. In OSPRay v1.x, geometries and volumes contained both structural and appearance information which limited their reuse in other objects. For example, the volume's transfer function can now be different between an isosurface, slice, and rendered volume all in the same scene without duplicating the actual volume itself. #### OSPGeometry and OSPVolume `OSPGeometry` and `OSPVolume` contain the physical data represented by the object. For geometries, this is the intersectable surface. For volumes, it is the scalar field to be sampled. #### OSPGeometricModel and OSPVolumetricModel `OSPGeometricModel` and `OSPVolumetricModel` contain appearance information about the geometry or volume that they hold. They have a one-to-N relationship with `OSPGeometry` and `OSPVolume` objects (i.e. a geometry or volume can exist in more than one model), but commonly exist as one-to-one. This could be used to create multiple copies of a geometry with different materials, for example. `OSPGeometricModel`s can hold primitive color information (e.g. the color used for each sphere in a `Spheres` geometry), a material or list of materials, and primitive material IDs (i.e. indexes into the list of materials if it is used). `OSPVolumetricModel`s can hold transfer functions. #### OSPGroup `OSPGroup` objects contain zero or more `OSPGeometricModel` and `OSPVolumetricModel` objects. They can hold geometries and volumes simultaneously. This is useful to collect together any objects that are logically grouped together in the scene. #### OSPInstance `OSPInstance` contains transformation information on an `OSPGroup` object. It has a one-to-one relationship with `OSPGroup`. This means that each `OSPInstance` contains exactly one `OSPGroup`. Similar to models and groups, a single `OSPGroup` may be placed into multiple `OSPInstace` objects. This allows for *instancing* of multiple objects throughout the scene, each with different transformations. `OSPInstance` objects holds an affine transformation matrix that is applied to all objects in its group. #### OSPWorld `OSPWorld` is the final container for all `OSPInstance` and `OSPLight` objects. It can contain one or more instances and lights. The world is passed along with a renderer, camera, and framebuffer to `ospRenderFrame` to generate an image. ### void ospRetain(OSPObject) To allow the user greater control over the lifetime of objects, a new API `ospRetain` has been introduced. This call increments an object's reference count, and can delay automatic deletion. Updated Public Parameter Names ------------------------------ OSPRay v2.0.0 has updated public parameter names (the strings used in `ospSetParam`) to a more consistent naming convention. OSPRay now will print a warning (visible if debug logs are enabled) if a parameter provided by the user is not used by an object. This can help catch cases where applications are using parameter names from OSPRay v1.8.5 or mistyped names. Some objects have required parameters. In these cases, OSPRay will invoke the error callback indicating which object and which parameter. OSPRay now universally uses the camelCase naming convention for all object types and parameter names. Furthermore, parameter names which are data arrays now use singular names to indicate what the elements are, and parameters which form a logical "struture-of-arrays" are communicated via the `"[structure_name].[member_name]"` naming convention. For example, the `"opacities"` array for `linear` transfer functions is now named `"opacity"`. Finally, some parameters have changed from being string-based to enum-based. All enums can be found in `OSPEnums.h`, where their usage can be found in the main API documentation. ospRenderFrame -------------- `ospRenderFrame` has changed in two ways. The signature has changed from: float ospRenderFrame(OSPFrameBuffer, OSPRenderer, const uint32_t frameBufferChannels = OSP_FB_COLOR); to OSPFuture ospRenderFrame(OSPFrameBuffer, OSPRenderer, OSPCamera, OSPWorld); And, notably, it is no longer blocking. Two new calls `ospIsReady`, and `ospWait` are available to manage synchronization. Utility Library --------------- As a convenience, a lightweight utility library has been provided to help users port from the previous versions and reduce boilerplate code. This set of additional API calls are all implemented in terms of the core API found in `ospray.h`, where they can be found in `ospray_util.h`. Their definitions are compiled into `libospray` (the `ospray::ospray` CMake target) and are compatible with any valid device implementation. ### OSPData and Parameter helpers The core OSPRay API has been simplified by removing many of the type specializations from the data and parameter set calls. The utility library provides wrappers to the familiar calls listed below: ospSetString(OSPObject, const char *n, const char *s); ospSetObject(OSPObject, const char *n, OSPObject obj); ospSetBool(OSPObject, const char *n, int x); ospSetFloat(OSPObject, const char *n, float x); ospSetInt(OSPObject, const char *n, int x); ospSetVec2f(OSPObject, const char *n, float x, float y); ospSetVec3f(OSPObject, const char *n, float x, float y, float z); ospSetVec4f(OSPObject, const char *n, float x, float y, float z, float w); ospSetVec2i(OSPObject, const char *n, int x, int y); ospSetVec3i(OSPObject, const char *n, int x, int y, int z); ospSetVec4i(OSPObject, const char *n, int x, int y, int z, int w); ospSetObjectAsData(OSPObject, const char *n, OSPDataType type, OSPObject obj); OSPRay v1.x calls to `ospSetData` have been replaced with `ospSetObject`. Convenience wrappers have also been provided to specialize `ospNewData`, and the new `ospNewSharedData` and `ospCopyData` APIs. ospNewSharedData1D(const void *sharedData, OSPDataType type, uint32_t numItems); ospNewSharedData1DStride(const void *sharedData, OSPDataType type, uint32_t numItems, int64_t byteStride); ospNewSharedData2D(const void *sharedData, OSPDataType type, uint32_t numItems1, uint32_t numItems2); ospNewSharedData2DStride(const void *sharedData, OSPDataType type, uint32_t numItems1, int64_t byteStride1, uint32_t numItems2, int64_t byteStride2); ospNewSharedData3D(const void *sharedData, OSPDataType type, uint32_t numItems1, uint32_t numItems2, uint32_t numItems3); ospNewData1D(OSPDataType type, uint32_t numItems); ospNewData2D(OSPDataType type, uint32_t numItems1, uint32_t numItems2); ospCopyData1D(const OSPData source, OSPData destination, uint32_t destinationIndex); ospCopyData2D(const OSPData source, OSPData destination, uint32_t destinationIndex1, uint32_t destinationIndex2); ### Object Usage Simplification To simplify setting data onto an object, if there is only a single data item, the wrapper `ospSetObjectAsData` permits the user to assign this item without first creating a data object containing that item. For example: OSPData geometricModels = ospNewSharedData1D(&model, OSP_GEOMETRIC_MODEL, 1); ospSetObject(group, "geometry", geometricModels); ospRelease(geometricModels); simply becomes: ospSetObjectAsData(group, "geometry", OSP_GEOMETRIC_MODEL, model); ### Rendering helpers While `ospRenderFrame` is now asynchronous, some users will prefer the original blocking behavior that returns the frame variance. The utility library provides a wrapper to this functionality: float ospRenderFrameBlocking(OSPFrameBuffer fb, OSPRenderer renderer, OSPCamera camera, OSPWorld world) RenderKit-ospray-85af292/doc/overview.md000066400000000000000000000044501464752671100202330ustar00rootroot00000000000000OSPRay Overview =============== Intel® OSPRay is an **o**pen source, **s**calable, and **p**ortable **ray** tracing engine for high-performance, high-fidelity visualization on Intel Architecture CPUs, Intel Xe GPUs, and ARM64 CPUs. OSPRay is part of the [Intel Rendering Toolkit (Render Kit)](https://software.intel.com/en-us/rendering-framework) and is released under the permissive [Apache 2.0 license](http://www.apache.org/licenses/LICENSE-2.0). The purpose of OSPRay is to provide an open, powerful, and easy-to-use rendering library that allows one to easily build applications that use ray tracing based rendering for interactive applications (including both surface- and volume-based visualizations). OSPRay runs on anything from laptops, to workstations, to compute nodes in HPC systems. OSPRay internally builds on top of Intel [Embree], Intel [Open VKL], and Intel [Open Image Denoise]. The CPU implementation is based on Intel [ISPC (Implicit SPMD Program Compiler)](https://ispc.github.io/) and fully exploits modern instruction sets like Intel SSE4, AVX, AVX2, AVX-512 and NEON to achieve high rendering performance. Hence, a CPU with support for at least SSE4.1 is required to run OSPRay on x86_64 architectures, or a CPU with support for NEON is required to run OSPRay on ARM64 architectures. OSPRay's GPU implementation (beta status) is based on the [SYCL](https://www.khronos.org/sycl/) cross-platform programming language implemented by [Intel oneAPI Data Parallel C++ (DPC++)](https://www.intel.com/content/www/us/en/developer/tools/oneapi/data-parallel-c-plus-plus.html) and currently supports Intel Arcâ„¢ GPUs on Linux and Windows, and Intel Data Center GPU Flex and Max Series on Linux, exploiting ray tracing hardware support.

=========================== The latest OSPRay sources are always available at the [OSPRay GitHub repository](http://github.com/ospray/ospray). The default `master` branch should always point to the latest bugfix release. Prerequisites ------------- OSPRay currently supports Linux, Mac OS\ X, and Windows. In addition, before you can build OSPRay you need the following prerequisites: - You can clone the latest OSPRay sources via: git clone https://github.com/ospray/ospray.git - To build OSPRay you need [CMake](http://www.cmake.org), any form of C++11 compiler (we recommend using GCC, but also support Clang, MSVC, and [Intel® C++ Compiler (icc)](https://software.intel.com/en-us/c-compilers)), and standard Linux development tools. - Additionally you require a copy of the [Intel® Implicit SPMD Program Compiler (ISPC)](http://ispc.github.io), version 1.23.0 or later. Please obtain a release of ISPC from the [ISPC downloads page](https://ispc.github.io/downloads.html). If ISPC is not found by CMake its location can be hinted with the variable `ISPC_EXECUTABLE`. - OSPRay builds on top of the [Intel Rendering Toolkit (Render Kit) common library (rkcommon)](https://www.github.com/ospray/rkcommon). The library provides abstractions for tasking, aligned memory allocation, vector math types, among others. For users who also need to build rkcommon, we recommend the default the Intel [Threading Building Blocks (TBB)](https://www.threadingbuildingblocks.org/) as tasking system for performance and flexibility reasons. TBB must be built from source when targeting ARM CPUs, or can be built from source as part of the [superbuild](#cmake-superbuild). Alternatively you can set CMake variable `RKCOMMON_TASKING_SYSTEM` to `OpenMP` or `Internal`. - OSPRay also heavily uses Intel [Embree], installing version 4.3.3 or newer is required. If Embree is not found by CMake its location can be hinted with the variable `embree_DIR`. - OSPRay supports volume rendering (enabled by default via `OSPRAY_ENABLE_VOLUMES`), which heavily uses Intel [Open VKL], version 2.0.1 or newer is required. If Open VKL is not found by CMake its location can be hinted with the variable `openvkl_DIR`, or disable `OSPRAY_ENABLE_VOLUMES`. - OSPRay also provides an optional module implementing the `denoiser` image operation, which is enabled by `OSPRAY_MODULE_DENOISER`. This module requires Intel [Open Image Denoise] in version 2.3.0 or newer. You may need to hint the location of the library with the CMake variable `OpenImageDenoise_DIR`. - For the optional MPI modules (enabled by `OSPRAY_MODULE_MPI`), which provide the `mpiOffload` and `mpiDistributed` devices, you need an MPI library and [Google Snappy](https://github.com/google/snappy). - The optional example application, the test suit and benchmarks need some version of OpenGL and GLFW as well as [GoogleTest](https://github.com/google/googletest) and [Google Benchmark](https://github.com/google/benchmark/) Depending on your Linux distribution you can install these dependencies using `yum` or `apt-get`. Some of these packages might already be installed or might have slightly different names. Type the following to install the dependencies using `yum`: sudo yum install cmake.x86_64 sudo yum install tbb.x86_64 tbb-devel.x86_64 Type the following to install the dependencies using `apt-get`: sudo apt-get install cmake-curses-gui sudo apt-get install libtbb-dev Under Mac OS\ X these dependencies can be installed using [MacPorts](http://www.macports.org/): sudo port install cmake tbb Under Windows please directly use the appropriate installers for [CMake](https://cmake.org/download/), [TBB](https://github.com/oneapi-src/oneTBB/releases), [ISPC](https://ispc.github.io/downloads.html) (for your Visual Studio version) and [Embree](https://github.com/embree/embree/releases/). ### Additional Prerequisites for GPU Build {-} To build OSPRay's GPU module you need - a SYCL compiler, either the open source [oneAPI DPC++ Compiler 2023-10-26](https://github.com/intel/llvm/releases/tag/nightly-2023-10-26) or the latest [Intel oneAPI DPC++/C++ Compiler](https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html#dpcpp-cpp) - a recent [CMake](http://www.cmake.org), version 3.25.3 or higher RenderKit-ospray-85af292/doc/pvospray.md000066400000000000000000000013021464752671100202410ustar00rootroot00000000000000OSPRay running inside ParaView ============================== [![](related_projects/vtk-paraview/screenshot-paraview-fiu-thumb.jpg)](related_projects/vtk-paraview/screenshot-paraview-fiu.jpg) This picture shows a ParaView plugin that allows ParaView to render through OSPRay, using a ParaView/VTK plugin developed by the Texas Advanced Computing Center.

An example of building `ospTutorial.c` with CMake can be found in [`apps/tutorials/ospTutorialFindospray/`](https://github.com/ospray/ospray/tree/master/apps/ospTutorial/ospTutorialFindospray). To build the tutorial on Linux, build it in a build directory with gcc -std=c99 ../apps/ospTutorial/ospTutorial.c \ -I ../ospray/include -L . -lospray -Wl,-rpath,. -o ospTutorial On Windows build it can be build manually in a "build_directory\\$Configuration" directory with cl ..\..\apps\ospTutorial\ospTutorial.c -I ..\..\ospray\include -I ..\.. ospray.lib Running `ospTutorial` will create two images of two triangles, rendered with the Scientific Visualization renderer with full Ambient Occlusion. The first image `firstFrame.ppm` shows the result after one call to `ospRenderFrame` – jagged edges and noise in the shadow can be seen. Calling `ospRenderFrame` multiple times enables progressive refinement, resulting in antialiased edges and converged shadows, shown after ten frames in the second image `accumulatedFrames.ppm`. ![First frame.][imgTutorial1] ![After accumulating ten frames.][imgTutorial2] ospExamples ----------- Apart from tutorials, `OSPRay` comes with a C++ app called [`ospExamples`](https://github.com/ospray/ospray/tree/master/apps/ospExamples) which is an elaborate easy-to-use tutorial, with a single interface to try various `OSPRay` features. It is aimed at providing users with multiple simple scenes composed of basic geometry types, lights, volumes etc. to get started with OSPRay quickly. `ospExamples` app runs a `GLFWOSPRayWindow` instance that manages instances of the camera, framebuffer, renderer and other OSPRay objects necessary to render an interactive scene. The scene is rendered on a `GLFW` window with an `imgui` GUI controls panel for the user to manipulate the scene at runtime. The application is located in [`apps/ospExamples/`](https://github.com/ospray/ospray/tree/master/apps/ospExamples) directory and can be built with CMake. It can be run from the build directory via: ``` ./ospExamples ``` The command line parameter is optional however. ![`ospExamples` application with default `boxes` scene.][imgOspExamples] ### Scenes Different scenes can be selected from the `scenes` dropdown and each scene corresponds to an instance of a special `detail::Builder` struct. Example builders are located in [`apps/common/ospray_testing/builders/`](https://github.com/ospray/ospray/tree/master/apps/common/ospray_testing/builders). These builders provide a usage guide for the OSPRay scene hierarchy and OSPRay API in the form of `cpp` wrappers. They instantiate and manage objects for the specific scene like `cpp::Geometry`, `cpp::Volume`, `cpp::Light` etc. The `detail::Builder` base struct is mostly responsible for setting up OSPRay `world` and objects common in all scenes (for example lighting and ground plane), which can be conveniently overridden in the derived builders. ### Renderer This app comes with four [renderer] options: `scivis`, `pathtracer`, `ao` and `debug`. The app provides some common rendering controls like `pixelSamples` and other more specific to the renderer type like `aoSamples` for the `scivis` and `ao` renderer or `maxPathLength` for the `pathtracer`. The sun-sky lighting can be used in a sample scene by enabling the `renderSunSky` option of the `pathtracer` renderer. It allows the user to change `turbidity` and `sunDirection`. ![Rendering an evening sky with the `renderSunSky` option.][imgRenderSunSky] ospMPIDistribTutorial --------------------- A minimal working example demonstrating how to use OSPRay for rendering distributed data can be found at [`modules/mpi/tutorials/ospMPIDistribTutorial.c`](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorial.c)^[A C++ version that uses the C++ convenience wrappers of OSPRay's C99 API via [`include/ospray/ospray_cpp.h`](https://github.com/ospray/ospray/blob/master/ospray/include/ospray/ospray_cpp.h) is available at [`modules/mpi/tutorials/ospMPIDistribTutorial.cpp`](https://github.com/ospray/ospray/blob/master/modules/mpi/tutorials/ospMPIDistribTutorial.cpp).]. The compilation process via CMake is the similar to [`apps/tutorials/ospTutorialFindospray/`](https://github.com/ospray/ospray/tree/master/apps/ospTutorial/ospTutorialFindospray), with the addition of finding and linking MPI. To build the tutorial on Linux, build it in a build directory with mpicc -std=c99 ../modules/mpi/tutorials/ospMPIDistribTutorial.c \ -I ../ospray/include -L . -lospray -Wl,-rpath,. -o ospMPIDistribTutorial On Windows build it can be build manually in a "build_directory\\$Configuration" directory with cl ..\..\modules\mpi\tutorials\ospMPIDistribTutorial.c -I ..\..\ospray\include -I ..\.. ospray.lib The MPI module does not need to be linked explicitly, as it is loaded as a module at runtime. ![The first frame output by the `ospMPIDistribTutorial` or C++ tutorial with 4 ranks.][imgMPIDistribTutorial1] ![The accumulated frame output by the `ospMPIDistribTutorial` or C++ tutorial with 4 ranks.][imgMPIDistribTutorial2] ospMPIDistribTutorialSpheres and ospMPIDistribTutorialVolume ------------------------------------------------------------ The spheres and volume distributed tutorials are built as part of the MPI tutorials when building OSPRay with the MPI module and tutorials enabled. These tutorials demonstrate using OSPRay to render distributed data sets where each rank owns some subregion of the data, and displaying the output in an interactive window. The domain is distributed in a grid among the processes, each of which will generate a subset of the data corresponding to its subdomain. In `ospMPIDistribTutorialSpheres`, each process generates a set of spheres within its assigned domain. The spheres are colored from dark to light blue, where lighter colors correspond to higher ranks. ![Running `ospMPIDistribTutorialSpheres` on 4 ranks.][imgMPIDistribTutorialSpheres] In `ospMPIDistribTutorialVolume`, each process generates a subbrick of volume data, which is colored by its rank. ![Running `ospMPIDistribTutorialVolume` on 4 ranks.][imgMPIDistribTutorialVolume] ospMPIDistribTutorialPartialRepl -------------------------------- The partially replicated MPI tutorial demonstrates how to use OSPRay's distributed rendering capabilities to render data sets that are partially replicated among the processes. Each pair of ranks generates the same volume brick, allowing them to subdivide the rendering workload between themselves. For example, when run with two ranks, each will generate the same brick and be responsible for rendering half of the image tiles it projects to. When run with four ranks, the pairs of ranks 0,1 and 2,3 will generate the same data and divide the rendering workload for that data among themselves. The image work subdivision happens automatically, based on which ranks specify the same bounding box for their data, as demonstrated in the tutorial. The partially replicated distribution is useful to support load-balanced rendering of data sets that are too large to be fully replicated among the processes, but are small enough to be partially replicated among them. ospMPIDistribTutorialReplicated ------------------------------- The replicated MPI tutorial demonstrates how OSPRay's distributed rendering capabilities can be used to render data sets that are fully replicated among the ranks with advanced illumination effects. In this case, although the processes are run MPI parallel, each rank specifies the exact same data. OSPRay's MPI parallel renderer will detect that the data is replicated in this case and use the same image-parallel rendering algorithms employed in the MPI offload rendering configuration to render the data. This image-parallel rendering algorithm supports all rendering configurations that are used in local rendering, e.g., path tracing, to provide high-quality images. The replicated MPI tutorial supports the same scenes and parameters as the [`ospExamples`][ospExamples] app described above. This mode can be useful when high-quality rendering is desired and it is possible to copy the entire data set on to each rank, or to accelerate loading of a large model by leveraging a parallel file system.

The sun was too bright: this affected both normal and alien sun scenarios. The coefficients of the solar radiance function were changed to fix this. 1.3 January 21st, 2013 (not released to the public) Added support for solar discs that are not exactly the same size as the terrestrial sun. Also added support for suns with a different emission spectrum ("Alien World" functionality). 1.2a December 18th, 2012 Fixed a mistake and some inaccuracies in the solar radiance function explanations found in ArHosekSkyModel.h. The actual source code is unchanged compared to version 1.2. 1.2 December 17th, 2012 Native RGB data and a solar radiance function that matches the turbidity conditions were added. 1.1 September 2012 The coefficients of the spectral model are now scaled so that the output is given in physical units: W / (m^-2 * sr * nm). Also, the output of the XYZ model is now no longer scaled to the range [0...1]. Instead, it is the result of a simple conversion from spectral data via the CIE 2 degree standard observer matching functions. Therefore, after multiplication with 683 lm / W, the Y channel now corresponds to luminance in lm. 1.0 May 11th, 2012 Initial release.

The sun was too bright: this affected both normal and alien sun scenarios. The coefficients of the solar radiance function were changed to fix this. 1.3 January 21st, 2013 (not released to the public) Added support for solar discs that are not exactly the same size as the terrestrial sun. Also added support for suns with a different emission spectrum ("Alien World" functionality). 1.2a December 18th, 2012 Fixed a mistake and some inaccuracies in the solar radiance function explanations found in ArHosekSkyModel.h. The actual source code is unchanged compared to version 1.2. 1.2 December 17th, 2012 Native RGB data and a solar radiance function that matches the turbidity conditions were added. 1.1 September 2012 The coefficients of the spectral model are now scaled so that the output is given in physical units: W / (m^-2 * sr * nm). Also, the output of the XYZ model is now no longer scaled to the range [0...1]. Instead, it is the result of a simple conversion from spectral data via the CIE 2 degree standard observer matching functions. Therefore, after multiplication with 683 lm / W, the Y channel now corresponds to luminance in lm. 1.0 May 11th, 2012 Initial release. Please visit http://cgg.mff.cuni.cz/projects/SkylightModelling/ to check if an updated version of this code has been published! ============================================================================ */ /* This code is taken from ART, a rendering research system written in a mix of C99 / Objective C. Since ART is not a small system and is intended to be inter-operable with other libraries, and since C does not have namespaces, the structures and functions in ART all have to have somewhat wordy canonical names that begin with Ar.../ar..., like those seen in this example. Usage information: ================== Model initialisation -------------------- A separate ArHosekSkyModelState has to be maintained for each spectral band you want to use the model for. So in a renderer with 'num_channels' bands, you would need something like ArHosekSkyModelState * skymodel_state[num_channels]; You then have to allocate and initialise these states. In the following code snippet, we assume that 'albedo' is defined as float albedo[num_channels]; with a ground albedo value between [0,1] for each channel. The solar elevation is given in radians. for ( unsigned int i = 0; i < num_channels; i++ ) skymodel_state[i] = arhosekskymodelstate_alloc_init( turbidity, albedo[i], solarElevation ); Note that starting with version 1.3, there is also a second initialisation function which generates skydome states for different solar emission spectra and solar radii: 'arhosekskymodelstate_alienworld_alloc_init()'. See the notes about the "Alien World" functionality provided further down for a discussion of the usefulness and limits of that second initialisation function. Sky model states that have been initialised with either function behave in a completely identical fashion during use and cleanup. Using the model to generate skydome samples ------------------------------------------- Generating a skydome radiance spectrum "skydome_result" for a given location on the skydome determined via the angles theta and gamma works as follows: float skydome_result[num_channels]; for ( unsigned int i = 0; i < num_channels; i++ ) skydome_result[i] = arhosekskymodel_radiance( skymodel_state[i], theta, gamma, channel_center[i] ); The variable "channel_center" is assumed to hold the channel center wavelengths for each of the num_channels samples of the spectrum we are building. Cleanup after use ----------------- After rendering is complete, the content of the sky model states should be disposed of via for ( unsigned int i = 0; i < num_channels; i++ ) arhosekskymodelstate_free( skymodel_state[i] ); CIE XYZ Version of the Model ---------------------------- Usage of the CIE XYZ version of the model is exactly the same, except that num_channels is of course always 3, and that ArHosekTristimSkyModelState and arhosek_tristim_skymodel_radiance() have to be used instead of their spectral counterparts. RGB Version of the Model ------------------------ The RGB version uses sRGB primaries with a linear gamma ramp. The same set of functions as with the XYZ data is used, except the model is initialized by calling arhosek_rgb_skymodelstate_alloc_init. Solar Radiance Function ----------------------- For each position on the solar disc, this function returns the entire radiance one sees - direct emission, as well as in-scattered light in the area of the solar disc. The latter is important for low solar elevations - nice images of the setting sun would not be possible without this. This is also the reason why this function, just like the regular sky dome model evaluation function, needs access to the sky dome data structures, as these provide information on in-scattered radiance. CAVEAT #1: in this release, this function is only provided in spectral form! RGB/XYZ versions to follow at a later date. CAVEAT #2: (fixed from release 1.3 onwards) CAVEAT #3: limb darkening renders the brightness of the solar disc inhomogeneous even for high solar elevations - only taking a single sample at the centre of the sun will yield an incorrect power estimate for the solar disc! Always take multiple random samples across the entire solar disc to estimate its power! CAVEAT #4: in this version, the limb darkening calculations still use a fairly computationally expensive 5th order polynomial that was directly taken from astronomical literature. For the purposes of Computer Graphics, this is needlessly accurate, though, and will be replaced by a cheaper approximation in a future release. "Alien World" functionality --------------------------- The Hosek sky model can be used to roughly (!) predict the appearance of outdoor scenes on earth-like planets, i.e. planets of a similar size and atmospheric make-up. Since the spectral version of our model predicts sky dome luminance patterns and solar radiance independently for each waveband, and since the intensity of each waveband is solely dependent on the input radiance from the star that the world in question is orbiting, it is trivial to re-scale the wavebands to match a different star radiance. At least in theory, the spectral version of the model has always been capable of this sort of thing, and the actual sky dome and solar radiance models were actually not altered at all in this release. All we did was to add some support functionality for doing this more easily with the existing data and functions, and to add some explanations. Just use 'arhosekskymodelstate_alienworld_alloc_init()' to initialise the sky model states (you will have to provide values for star temperature and solar intensity compared to the terrestrial sun), and do everything else as you did before. CAVEAT #1: we assume the emission of the star that illuminates the alien world to be a perfect blackbody emission spectrum. This is never entirely realistic - real star emission spectra are considerably more complex than this, mainly due to absorption effects in the outer layers of stars. However, blackbody spectra are a reasonable first assumption in a usage scenario like this, where 100% accuracy is simply not necessary: for rendering purposes, there are likely no visible differences between a highly accurate solution based on a more involved simulation, and this approximation. CAVEAT #2: we always use limb darkening data from our own sun to provide this "appearance feature", even for suns of strongly different temperature. Which is presumably not very realistic, but (as with the unaltered blackbody spectrum from caveat #1) probably not a bad first guess, either. If you need more accuracy than we provide here, please make inquiries with a friendly astro-physicst of your choice. CAVEAT #3: you have to provide a value for the solar intensity of the star which illuminates the alien world. For this, please bear in mind that there is very likely a comparatively tight range of absolute solar irradiance values for which an earth-like planet with an atmosphere like the one we assume in our model can exist in the first place! Too much irradiance, and the atmosphere probably boils off into space, too little, it freezes. Which means that stars of considerably different emission colour than our sun will have to be fairly different in size from it, to still provide a reasonable and inhabitable amount of irradiance. Red stars will need to be much larger than our sun, while white or blue stars will have to be comparatively tiny. The initialisation function handles this and computes a plausible solar radius for a given emission spectrum. In terms of absolute radiometric values, you should probably not stray all too far from a solar intensity value of 1.0. CAVEAT #4: although we now support different solar radii for the actual solar disc, the sky dome luminance patterns are *not* parameterised by this value - i.e. the patterns stay exactly the same for different solar radii! Which is of course not correct. But in our experience, solar discs up to several degrees in diameter (! - our own sun is half a degree across) do not cause the luminance patterns on the sky to change perceptibly. The reason we know this is that we initially used unrealistically large suns in our brute force path tracer, in order to improve convergence speeds (which in the beginning were abysmal). Later, we managed to do the reference renderings much faster even with realistically small suns, and found that there was no real difference in skydome appearance anyway. Conclusion: changing the solar radius should not be over-done, so close orbits around red supergiants are a no-no. But for the purposes of getting a fairly credible first impression of what an alien world with a reasonably sized sun would look like, what we are doing here is probably still o.k. HINT #1: if you want to model the sky of an earth-like planet that orbits a binary star, just super-impose two of these models with solar intensity of ~0.5 each, and closely spaced solar positions. Light is additive, after all. Tattooine, here we come... :-) P.S. according to Star Wars canon, Tattooine orbits a binary that is made up of a G and K class star, respectively. So ~5500K and ~4200K should be good first guesses for their temperature. Just in case you were wondering, after reading the previous paragraph. */ #ifndef _ARHOSEK_SKYMODEL_H_ #define _ARHOSEK_SKYMODEL_H_ typedef float ArHosekSkyModelConfiguration[9]; // Spectral version of the model /* ---------------------------------------------------------------------------- ArHosekSkyModelState struct --------------------------- This struct holds the pre-computation data for one particular albedo value. Most fields are self-explanatory, but users should never directly manipulate any of them anyway. The only consistent way to manipulate such structs is via the functions 'arhosekskymodelstate_alloc_init' and 'arhosekskymodelstate_free'. 'emission_correction_factor_sky' 'emission_correction_factor_sun' The original model coefficients were fitted against the emission of our local sun. If a different solar emission is desired (i.e. if the model is being used to predict skydome appearance for an earth-like planet that orbits a different star), these correction factors, which are determined during the alloc_init step, are applied to each waveband separately (they default to 1.0 in normal usage). This is the simplest way to retrofit this sort of capability to the existing model. The different factors for sky and sun are needed since the solar disc may be of a different size compared to the terrestrial sun. ---------------------------------------------------------------------------- */ typedef struct ArHosekSkyModelState { ArHosekSkyModelConfiguration configs[11]; float radiances[11]; float turbidity; float solar_radius; float emission_correction_factor_sky[11]; float emission_correction_factor_sun[11]; float albedo; float elevation; } ArHosekSkyModelState; /* ---------------------------------------------------------------------------- arhosekskymodelstate_alloc_init() function ------------------------------------------ Initialises an ArHosekSkyModelState struct for a terrestrial setting. ---------------------------------------------------------------------------- */ ArHosekSkyModelState *arhosekskymodelstate_alloc_init( const float solar_elevation, const float atmospheric_turbidity, const float ground_albedo); /* ---------------------------------------------------------------------------- arhosekskymodelstate_alienworld_alloc_init() function ----------------------------------------------------- Initialises an ArHosekSkyModelState struct for an "alien world" setting with a sun of a surface temperature given in 'kelvin'. The parameter 'solar_intensity' controls the overall brightness of the sky, relative to the solar irradiance on Earth. A value of 1.0 yields a sky dome that is, on average over the wavelengths covered in the model (!), as bright as the terrestrial sky in radiometric terms. Which means that the solar radius has to be adjusted, since the emissivity of a solar surface with a given temperature is more or less fixed. So hotter suns have to be smaller to be equally bright as the terrestrial sun, while cooler suns have to be larger. Note that there are limits to the validity of the luminance patterns of the underlying model: see the discussion above for more on this. In particular, an alien sun with a surface temperature of only 2000 Kelvin has to be very large if it is to be as bright as the terrestrial sun - so large that the luminance patterns are no longer a really good fit in that case. If you need information about the solar radius that the model computes for a given temperature (say, for light source sampling purposes), you have to query the 'solar_radius' variable of the sky model state returned *after* running this function. ---------------------------------------------------------------------------- */ ArHosekSkyModelState *arhosekskymodelstate_alienworld_alloc_init( const float solar_elevation, const float solar_intensity, const float solar_surface_temperature_kelvin, const float atmospheric_turbidity, const float ground_albedo); void arhosekskymodelstate_free(ArHosekSkyModelState *state); float arhosekskymodel_radiance( ArHosekSkyModelState *state, float theta, float gamma, float wavelength); // CIE XYZ and RGB versions ArHosekSkyModelState *arhosek_xyz_skymodelstate_alloc_init( const float turbidity, const float albedo, const float elevation); ArHosekSkyModelState *arhosek_rgb_skymodelstate_alloc_init( const float turbidity, const float albedo, const float elevation); float arhosek_tristim_skymodel_radiance( ArHosekSkyModelState *state, float theta, float gamma, int channel); // Delivers the complete function: sky + sun, including limb darkening. // Please read the above description before using this - there are several // caveats! float arhosekskymodel_solar_radiance( ArHosekSkyModelState *state, float theta, float gamma, float wavelength); float arhosekskymodel_solar_radiance_internal2(ArHosekSkyModelState *state, float wavelength, float elevation, float gamma); #endif // _ARHOSEK_SKYMODEL_H_ RenderKit-ospray-85af292/modules/cpu/lights/sky_model/sky_model_data_ciexyz.h000066400000000000000000002303761464752671100275500ustar00rootroot00000000000000/* This source is published under the following 3-clause BSD license.

The sun was too bright: this affected both normal and alien sun scenarios. The coefficients of the solar radiance function were changed to fix this. 1.3 January 21st, 2013 (not released to the public) Added support for solar discs that are not exactly the same size as the terrestrial sun. Also added support for suns with a different emission spectrum ("Alien World" functionality). 1.2a December 18th, 2012 Fixed a mistake and some inaccuracies in the solar radiance function explanations found in ArHosekSkyModel.h. The actual source code is unchanged compared to version 1.2. 1.2 December 17th, 2012 Native RGB data and a solar radiance function that matches the turbidity conditions were added. 1.1 September 2012 The coefficients of the spectral model are now scaled so that the output is given in physical units: W / (m^-2 * sr * nm). Also, the output of the XYZ model is now no longer scaled to the range [0...1]. Instead, it is the result of a simple conversion from spectral data via the CIE 2 degree standard observer matching functions. Therefore, after multiplication with 683 lm / W, the Y channel now corresponds to luminance in lm. 1.0 May 11th, 2012 Initial release. Please visit http://cgg.mff.cuni.cz/projects/SkylightModelling/ to check if an updated version of this code has been published!

The sun was too bright: this affected both normal and alien sun scenarios. The coefficients of the solar radiance function were changed to fix this. 1.3 January 21st, 2013 (not released to the public) Added support for solar discs that are not exactly the same size as the terrestrial sun. Also added support for suns with a different emission spectrum ("Alien World" functionality). 1.2a December 18th, 2012 Fixed a mistake and some inaccuracies in the solar radiance function explanations found in ArHosekSkyModel.h. The actual source code is unchanged compared to version 1.2. 1.2 December 17th, 2012 Native RGB data and a solar radiance function that matches the turbidity conditions were added. 1.1 September 2012 The coefficients of the spectral model are now scaled so that the output is given in physical units: W / (m^-2 * sr * nm). Also, the output of the XYZ model is now no longer scaled to the range [0...1]. Instead, it is the result of a simple conversion from spectral data via the CIE 2 degree standard observer matching functions. Therefore, after multiplication with 683 lm / W, the Y channel now corresponds to luminance in lm. 1.0 May 11th, 2012 Initial release. Please visit http://cgg.mff.cuni.cz/projects/SkylightModelling/ to check if an updated version of this code has been published!

In particular, how this geometry can use its "commit()" method to query data the user has added to it. 2) how to use embree and ispc to implement this geometry type's intersect() and postIntersect() functoins 3) how to do this through a 'module' that is dynamically loadable; and 4) how to use this module - and geometry - from within your own applications Using this example you should be able to write your own modules, with your own geometry types. For the purpose of this geometry we have chosen a intentionally very simple type of geometry - a bilinear patch. Notes: - Names matter. E.g., for ospray to find the module "myModuleName" the module _has_ to build a library of name libospray_module_myModuleName.so. Similarly, a module that wants to define a new geometry type "MyGeometry" _has_ to have a OSPRAY_REGISTER_GEOMETRY(WhatEverYouCallItInYourImplementation,MyGeometry) macro invocation in one of its cpp files. - This example only demonstrates how to write a _geometry_ type. It is similarly possible to write new renderers, new camera types, new volume types, etc. Running the Example =================== Build OSPRay (make sure that OSPRAY_MODULE_BILINEAR_PATCH is on!), then in your build directory, do a ./ospExampleViewer --sg:module bilinear_patches ../modules/pluggableGeometryExample/examples/shadows.patches --renderer pt RenderKit-ospray-85af292/modules/pluggableGeometryExample/examples/000077500000000000000000000000001464752671100255535ustar00rootroot00000000000000RenderKit-ospray-85af292/modules/pluggableGeometryExample/examples/shadows.patches000066400000000000000000000003411464752671100305720ustar00rootroot00000000000000# a sample file of patches. any line that does not contain three # floats is ignored, and any set of four successive 3-float lines # form one bi-linear patch -1 -1 0 2 -1 0 -1 2 0 2 2 .1 0 0 -.02 1 0 -.02 0 1 -.02 1 1 -.1 RenderKit-ospray-85af292/modules/pluggableGeometryExample/examples/test1.patches000066400000000000000000000003561464752671100301700ustar00rootroot00000000000000# a sample file of patches. any line that does not contain three # floats is ignored, and any set of four successive 3-float lines # form one bi-linear patch 0 0 0 1 0 0 0 0 .1 1 1 .1 2 2 2 2 2 3 2 3 2 2 3 3 2 0 1 2 1 0 3 1 1 3 0 0 RenderKit-ospray-85af292/modules/pluggableGeometryExample/ospray/000077500000000000000000000000001464752671100252525ustar00rootroot00000000000000RenderKit-ospray-85af292/modules/pluggableGeometryExample/ospray/CMakeLists.txt000066400000000000000000000041751464752671100300210ustar00rootroot00000000000000## Copyright 2009 Intel Corporation ## SPDX-License-Identifier: Apache-2.0 # this subdirectory builds the actual ospray plugin into a library # "libospray_module_.so". # # This shared library can depend on libospray, but should _not_ assume # that it is living in the same address space as the application: When # running in MPI mode ospray will, upon encountering the # ospLoadModule(""), actually load and use this library on # every worker node (which will typically not run the application).

By default, the result is an install directory, with each dependency in its own directory. Run with: ```sh mkdir build cd build cmake [/scripts/superbuild] cmake --build . ``` On Windows make sure to select a 64\ bit generator, e.g. ```sh cmake -G "Visual Studio 17 2022" [/scripts/superbuild] ``` The resulting `install` directory (or the one set with `CMAKE_INSTALL_PREFIX`) will have everything in it, with one subdirectory per dependency. CMake options to note (all have sensible defaults): CMAKE_INSTALL_PREFIX : will be the root directory where everything gets installed. BUILD_JOBS : sets the number given to `make -j` for parallel builds. INSTALL_IN_SEPARATE_DIRECTORIES : toggles installation of all libraries in separate or the same directory. BUILD_OPENVKL : whether to enable volume rendering via Open VKL BUILD_EMBREE_FROM_SOURCE : set to OFF will download a pre-built version of Embree. BUILD_OIDN_FROM_SOURCE : set to OFF will download a pre-built version of Open Image Denoise. OIDN_VERSION : determines which version of Open Image Denoise to pull down. BUILD_OSPRAY_MODULE_MPI : set to ON to build OSPRay’s MPI module for data-replicated and distributed parallel rendering on multiple nodes. BUILD_GPU_SUPPORT : enables beta GPU support, fetching the SYCL variants of the dependencies and builds `OSPRAY_MODULE_GPU` BUILD_TBB_FROM_SOURCE : set to ON to build TBB from source (required for ARM support). The default setting is OFF. For the full set of options, run: ```sh ccmake [/scripts/superbuild] ``` or ```sh cmake-gui [/scripts/superbuild] ``` ### Cross-Compilation with the Superbuild The superbuild can be passed a [CMake Toolchain file](https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html) to configure for cross-compilation. This is done by passing the toolchain file when running cmake. When cross compiling it is also likely that you’ll want to build TBB and Embree from source to ensure they’re built for the correct target, rather than the target the Github binaries are built for. It may also be necessary to disable specific ISAs for the target by passing `BUILD_ISA_=OFF` as well. ```sh mkdir build cd build cmake --toolchain [toolchain_file.cmake] [path/to/this/directory] -DBUILD_TBB_FROM_SOURCE=ON \ -DBUILD_EMBREE_FROM_SOURCE=ON \ ``` While OSPRay supports ARM natively, it may be desirable to cross-compile it for `x86_64` to run in Rosetta depending on the application integrating OSPRay. This can be done using the toolchain file `toolchains/macos-rosetta.cmake`, and by disabling all non-SSE ISAs when building. This can also be done by launching an `x86_64` bash shell and then compiling as usual in this environment, which will cause the compilation chain to target `x86_64`.

PATH and LD_LIBRARY_PATH should contain ${OSPRAY_BUILD_DIR}. 1. Build OSPRay Compile OSPRay in a build directory of your choosing. We will refer to this directory as ${OSPRAY_BUILD_DIR}. 2. Generate baseline images (OPTIONAL) Build OSPRay with OSPRAY_TESTING on. Only generate new images for a test that has changed. To generate new images for a specific test run ./ospTestSuite --gtest_filter="*TESTNAME*" --dump-img --baseline-dir=test_image_data/ which will create images in a folder called test_image_data. To make new images for all tests, In ${OSPRAY_BUILD_DIR}, run the "generate_baseline.sh" script: % ${OSPRAY_SOURCE_DIR}/scripts/tests/generate_baseline.sh This will output generated images in a folder named generated_test_images. These images will not automatically be used as baseline images for the tests unless put into the correct folder (/build_regression_tests/regression_test_baseline/) or the update script is used (5). 3. Run regression tests To verify whether a change to the codebase broke anything, run % ${OSPRAY_SOURCE_DIR}/scripts/tests/run_tests.sh ${OSPRAY_SOURCE_DIR} * where ISA is empty if using own generated images, or "AVX2" or "AVX512SKX" to * download golden images for that ISA target This will download golden baseline images into a folder named build_regression_tests/regression_test_baseline in the current working directory (OSPRAY_BUILD_DIR) and run tests to compare them. 4. To run an individual test ./ospTestSuite --gtest_list_tests this will output a list of test names ./ospTestSuite --gest_filter="*NAME*" will run a single test 5. Add or update generated test images to ospray Use the included update_test_baseline.sh script and then send the resulting files to ospray developers or do the following steps: call md5sum on the resulting .png files. Add a .png.md5 file to tests/baseling/TESTNAME.png.md5 with the value of the checksum. rename the .png file to be the checksum value, and then send this to OSPRay Devs who will add it to https://github.com/ospray/ospray-test-data / https://www.ospray.org/ospray-test-data/.

If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed. 4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions: (a) You must give any other recipients of the Work or Derivative Works a copy of this License; and (b) You must cause any modified files to carry prominent notices stating that You changed the files; and (c) You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and (d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear. The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License. You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License. 5.

GCC RUNTIME LIBRARY EXCEPTION Version 3.1, 31 March 2009 Copyright (C) 2009 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This GCC Runtime Library Exception ("Exception") is an additional permission under section 7 of the GNU General Public License, version 3 ("GPLv3"). It applies to a given file (the "Runtime Library") that bears a notice placed by the copyright holder of the file stating that the file is governed by GPLv3 along with this Exception. When you use GCC to compile a program, GCC may combine portions of certain GCC header files and runtime libraries with the compiled program. The purpose of this Exception is to allow compilation of non-GPL (including proprietary) programs to use, in this way, the header files and runtime libraries covered by this Exception. 0. Definitions. A file is an "Independent Module" if it either requires the Runtime Library for execution after a Compilation Process, or makes use of an interface provided by the Runtime Library, but is not otherwise based on the Runtime Library. "GCC" means a version of the GNU Compiler Collection, with or without modifications, governed by version 3 (or a specified later version) of the GNU General Public License (GPL) with the option of using any subsequent versions published by the FSF. "GPL-compatible Software" is software whose conditions of propagation, modification and use would permit combination with GCC in accord with the license of GCC. "Target Code" refers to output from any compiler for a real or virtual target processor architecture, in executable form or suitable for input to an assembler, loader, linker and/or execution phase. Notwithstanding that, Target Code does not include data in any format that is used as a compiler intermediate representation, or used for producing a compiler intermediate representation. The "Compilation Process" transforms code entirely represented in non-intermediate languages designed for human-written code, and/or in Java Virtual Machine byte code, into Target Code. Thus, for example, use of source code generators and preprocessors need not be considered part of the Compilation Process, since the Compilation Process can be understood as starting with the output of the generators or preprocessors. A Compilation Process is "Eligible" if it is done using GCC, alone or with other GPL-compatible software, or if it is done without using any work based on GCC. For example, using non-GPL-compatible Software to optimize any GCC intermediate representations would not qualify as an Eligible Compilation Process. 1. Grant of Additional Permission. You have permission to propagate a work of Target Code formed by combining the Runtime Library with Independent Modules, even if such propagation would otherwise violate the terms of GPLv3, provided that all Target Code was generated by Eligible Compilation Processes. You may then convey such a combination under terms of your choice, consistent with the licensing of the Independent Modules. 2. No Weakening of GCC Copyleft. The availability of this Exception does not imply any general presumption that third-party software is unaffected by the copyleft requirements of the license of GCC. libquadmath/*.[hc]: Copyright (C) 2010 Free Software Foundation, Inc.

Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. 6. Disclaimer of Warranty Covered Software is provided under this License on an "as is" basis, without warranty of any kind, either expressed, implied, or statutory, including, without limitation, warranties that the Covered Software is free of defects, merchantable, fit for a particular purpose or non-infringing. The entire risk as to the quality and performance of the Covered Software is with You. Should any Covered Software prove defective in any respect, You (not any Contributor) assume the cost of any necessary servicing, repair, or correction. This disclaimer of warranty constitutes an essential part of this License. No use of any Covered Software is authorized under this License except under this disclaimer. 7. Limitation of Liability Under no circumstances and under no legal theory, whether tort (including negligence), contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as permitted above, be liable to You for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for lost profits, loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, even if such party shall have been informed of the possibility of such damages. This limitation of liability shall not apply to liability for death or personal injury resulting from such party's negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You. 8. Litigation Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party's ability to bring cross-claims or counter-claims. 9. Miscellaneous This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor. 10. Versions of the License 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached. Exhibit A - Source Code Form License Notice This Source Code Form is subject to the terms of the Mozilla Public License, v. 2.0.

Mateusz Kwiatkowski Workaround for bug 62258 in libstdc++ GPL 3.0 with GCC Runtime Library Exception 3.1 GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (c) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . GCC RUNTIME LIBRARY EXCEPTION Version 3.1, 31 March 2009 Copyright (c) 2009 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This GCC Runtime Library Exception ("Exception") is an additional permission under section 7 of the GNU General Public License, version 3 ("GPLv3"). It applies to a given file (the "Runtime Library") that bears a notice placed by the copyright holder of the file stating that the file is governed by GPLv3 along with this Exception. When you use GCC to compile a program, GCC may combine portions of certain GCC header files and runtime libraries with the compiled program. The purpose of this Exception is to allow compilation of non-GPL (including proprietary) programs to use, in this way, the header files and runtime libraries covered by this Exception. 0. Definitions. A file is an "Independent Module" if it either requires the Runtime Library for execution after a Compilation Process, or makes use of an interface provided by the Runtime Library, but is not otherwise based on the Runtime Library. "GCC" means a version of the GNU Compiler Collection, with or without modifications, governed by version 3 (or a specified later version) of the GNU General Public License (GPL) with the option of using any subsequent versions published by the FSF. "GPL-compatible Software" is software whose conditions of propagation, modification and use would permit combination with GCC in accord with the license of GCC. "Target Code" refers to output from any compiler for a real or virtual target processor architecture, in executable form or suitable for input to an assembler, loader, linker and/or execution phase. Notwithstanding that, Target Code does not include data in any format that is used as a compiler intermediate representation, or used for producing a compiler intermediate representation. The "Compilation Process" transforms code entirely represented in non-intermediate languages designed for human-written code, and/or in Java Virtual Machine byte code, into Target Code. Thus, for example, use of source code generators and preprocessors need not be considered part of the Compilation Process, since the Compilation Process can be understood as starting with the output of the generators or preprocessors. A Compilation Process is "Eligible" if it is done using GCC, alone or with other GPL-compatible software, or if it is done without using any work based on GCC. For example, using non-GPL-compatible Software to optimize any GCC intermediate representations would not qualify as an Eligible Compilation Process. 1. Grant of Additional Permission. You have permission to propagate a work of Target Code formed by combining the Runtime Library with Independent Modules, even if such propagation would otherwise violate the terms of GPLv3, provided that all Target Code was generated by Eligible Compilation Processes. You may then convey such a combination under terms of your choice, consistent with the licensing of the Independent Modules. 2. No Weakening of GCC Copyleft. The availability of this Exception does not imply any general presumption that third-party software is unaffected by the copyleft requirements of the license of GCC. _______________________________________________________________________________________________________ 5.
