## There are various ways to get dependency output from gcc. Here's

## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.

\`configure' configures mesa-demos 8.1.0 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]

/* Example for PC game developers to show how to *combine* texturing,
reflections, and projected shadows all in real-time with OpenGL.
Robust reflections use stenciling. Robust projected shadows
use both stenciling and polygon offset. PC game programmers
should realize that neither stenciling nor polygon offset are
supported by Direct3D, so these real-time rendering algorithms
are only really viable with OpenGL.
The program has modes for disabling the stenciling and polygon
offset uses. It is worth running this example with these features
toggled off so you can see the sort of artifacts that result.
Notice that the floor texturing, reflections, and shadowing
all co-exist properly. */
/* When you run this program: Left mouse button controls the
view. Middle mouse button controls light position (left &
right rotates light around dino; up & down moves light
position up and down). Right mouse button pops up menu. */

reflection blending and surface stenciling is done. You can
also see in "redraw" how the projected shadows are rendered,
including the use of stenciling and polygon offset. */

* Draw the "fire" test program on the six faces of a cube using
* fbo render-to-texture.
*
* Much of the code comes from David Bucciarelli's "fire"
* test program. The rest basically from Brian Paul's "gearbox" and
* fbotexture programs.
*
* By pressing the 'q' key, you can make the driver choose different
* internal texture RGBA formats by giving it different "format" and "type"
* arguments to the glTexImage2D function that creates the texture
* image being rendered to. If the driver doesn't support a texture image
* format as a render target, it will usually fall back to software when
* drawing the "fire" image, and frame-rate should drop considerably.
*
* Performance:
* The rendering speed of this program is usually dictated by fill rate
* and the fact that software fallbacks for glBitMap makes the driver
* operate synchronously. Low-end UMA hardware will probably see around
* 35 fps with the help screen disabled and 32bpp window- and user
* frame-buffers (2008).
*
* This program is released under GPL, following the "fire" licensing.
*
* Authors:
* David Bucciarelli ("fire")
* Brian Paul ("gearbox", "fbotexture")
* Thomas Hellstrom (Putting it together)

------------
This directory is usually included in the Mesa demos distribution or
in the GLUT distribution.
I have written the demos included in this directory mainly for showing
the capabilities of the Mesa library when using the Voodoo driver.
However all the demos are written using the GLUT and OpenGL so they
work with any GLUT/OpenGL platform (tested: Linux+Mesa+Voodoo driver,
Linux+Mesa+X11 driver, Win95+Mesa+Voodoo driver and SGI Onyx IR thanks
to Mark Kilgard).
All the demos make an heavy use of texture mapping, blending, etc. so
you _need_ some kind of hardware support for the OpenGL otherwise they
will run at ~1fps. You need also a OpenGL 1.1 compliant library.
You can find some screenshot of these demos at
http://www-hmw.caribel.pisa.it/fxmesa/fxdemos.hmtl
Write me if you find some bug in the demos.

A BRIEF DESCRIPTION OF THE DEMOS
--------------------------------
IPERS
-----
Sources: ipers.c image.c
A nice spinning fractal object.
RAY
---
Sources: ray.c
I'm using ray tracing to dynamically generate texture maps with
specular, diffuse, shadows, and mirror colors. Each frame the texture
maps of the plane and of the sphere are partially updated. With this
technique you can obtain true mirrors, shadows, specular highlights,
bump mapping, etc. in realtime. This demo is really CPU intensive
(~25fps on a PentiumII@300MHz with a Pure3D). Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TUNNEL
------
Sources: tunnel.c image.c sources.c
Data: bw.rgb tile.rgb
The model was designed and prelighted with Alias|Wavefront
PowerAnimator V8. Triangle strips were built with a tool written by me
and then statically included in the sources. This demo doesn't
require the ZBuffer and use antialiased polygons. Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TUNNEL2
------
Sources: tunnel2.c image.c sources.c
Data: bw.rgb tile.rgb
The some tunnel demo but with two output channels. A nice
example of the Mesa/Voodoo support for multiple boards in
the some PC.
TEAPOT
------
Sources: teapot.c image.c dteapot.c shadow.c
Data: bw.rgb tile.rgb
The shadow is drawn projecting the teapot geometry over the plane. All
other light effects are drawn using the standard OpenGL capabilities.
Support on-the-fly switching between fullscreen and in-window
rendering under Linux/Mesa (start your X server in 16 bpp mode and
press the spacebar).
FIRE
----
Sources: fire.c image.c
Data: s128.rgb tree2.rgb
The demo use a small particle system to draw some nice visual effect.
You can interactively change many parameters of the particle system
and you can choose the number of particles at the startup ('fire
4000'). This demo should be called fountain. Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TERRAIN
-------
Sources: mesaland.c
This demo is base on another demo written by Mikael SkiZoWalker. I
have added the capabilities to freely fly around, view culling and
some nice color. Support on-the-fly switching between fullscreen and
in-window rendering under Linux/Mesa (start your X server in 16 bpp
mode and press the spacebar).
GLTEST
------
Sources: gltest.c
This is a simple benchmark suite that I'm using in the development of
the Mesa/Voodoo driver. Type 'gltest >my.res' and you will get some
data about the performances of your OpenGL. Follow the results with my
PC (Linux+Mesa-2.6+PentiumII@300MHz+Pure3D):

PALTEX and GLBPALTX
-------------------
Sources: paltex.c and glbpaltx.c
The PALTEX example was written by Brian Paul and it shows the
capabilities of the GL_EXT_paletted_texture extension. I have written
the other example in order to show the capabilities of the
gl3DfxSetPaletteEXT() (it used only by GLQuake and Quake2).

/*
* GLUT demonstration of texturing with specular highlights.
*
* When drawing a lit, textured surface one usually wants the specular
* highlight to override the texture colors. However, OpenGL applies
* texturing after lighting so the specular highlight is modulated by
* the texture.
*
* The solution here shown here is a two-pass algorithm:
* 1. Draw the textured surface without specular lighting.
* 2. Enable blending to add the next pass:
* 3. Redraw the surface with a matte white material and only the
* specular components of light sources enabled.

* Demo of (nearly) flicker-free drawing with a single color buffer.
*
* Basically, draw the scene into the Z buffer first, then draw the
* scene into the color buffer. Finally, "clear" the background by
* setting the fragments we didn't hit earlier.
*
* This won't work if you need blending. The technique works best

/* Draw test patterns to help determine correct gamma value for a display.
When the intensities of the inner squares nearly match the intensities
of their frames (from some distance the borders should disappear) then
you've found the right gamma value.
You can set Mesa's gamma values (for red, green and blue) with the
MESA_GAMMA environment variable. But only on X windows!
For example:
setenv MESA_GAMMA 1.5 1.6 1.4
Sets the red gamma value to 1.5, green to 1.6 and blue to 1.4.
See the main README file for more information.
For more info about gamma correction see:
