Both licenses pass the common definition of 'open source license' as commonly defined (e.g. at http://www.opensource.org). The licenses, although different, are compatible with each other. The applicable licenses are: examples, man pages, documentation: Artistic License A copy of this license is in COPYING.artistic source code: IBM standard example source code license (free use, free distribution, free modification, disclaimer of warrenty) A copy of this license is in COPYING.src The file CERTOR.script ('certificate of originality') documents the provenance of this code. -------------------------------------------------------------------- Alternately, at your choosing, you may choose to accept the source code and the man pages/documentation under the GPL: the GNU General Public License version 2, as given below. If you use this code, you must accept either the licenses above, or the GPL. -------------------------------------------------------------------- GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the 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 a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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. 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 convey 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 2 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, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision 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, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This 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 Library General Public License instead of this License. gle-3.1.2/ChangeLog000066400000000000000000000002021446777505400140530ustar00rootroot00000000000000 Oct 18, 2001: * There is no formal ChangeLog for this project; see, however, doc/html/index.html for an informal changelog. gle-3.1.2/INSTALL000066400000000000000000000000061446777505400133340ustar00rootroot00000000000000blank gle-3.1.2/Makefile.am000066400000000000000000000002701446777505400143420ustar00rootroot00000000000000 SUBDIRS = src doc examples man ms-visual-c swig ACLOCAL_AMFLAGS = -I m4 EXTRA_DIST = \ .cvsignore \ gle.spec docdir = $(datadir)/doc/gle/ doc_DATA = AUTHORS README.md COPYING gle-3.1.2/Makefile.in000066400000000000000000000660461446777505400143700ustar00rootroot00000000000000# Makefile.in generated by automake 1.16.3 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2020 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__is_gnu_make = { \ if test -z '$(MAKELEVEL)'; then \ false; \ elif test -n '$(MAKE_HOST)'; then \ true; \ elif test -n '$(MAKE_VERSION)' && test -n '$(CURDIR)'; then \ true; \ else \ false; \ fi; \ } am__make_running_with_option = \ case $${target_option-} in \ ?) ;; \ *) echo "am__make_running_with_option: internal error: invalid" \ "target option '$${target_option-}' specified" >&2; \ exit 1;; \ esac; \ has_opt=no; \ sane_makeflags=$$MAKEFLAGS; \ if $(am__is_gnu_make); then \ sane_makeflags=$$MFLAGS; \ else \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ bs=\\; \ sane_makeflags=`printf '%s\n' "$$MAKEFLAGS" \ | sed "s/$$bs$$bs[$$bs $$bs ]*//g"`;; \ esac; \ fi; \ skip_next=no; \ strip_trailopt () \ { \ flg=`printf '%s\n' "$$flg" | sed "s/$$1.*$$//"`; \ }; \ for flg in $$sane_makeflags; do \ test $$skip_next = yes && { skip_next=no; continue; }; \ case $$flg in \ *=*|--*) continue;; \ -*I) strip_trailopt 'I'; skip_next=yes;; \ -*I?*) strip_trailopt 'I';; \ -*O) strip_trailopt 'O'; skip_next=yes;; \ -*O?*) strip_trailopt 'O';; \ -*l) strip_trailopt 'l'; skip_next=yes;; \ -*l?*) strip_trailopt 'l';; \ -[dEDm]) skip_next=yes;; \ -[JT]) skip_next=yes;; \ esac; \ case $$flg in \ *$$target_option*) has_opt=yes; break;; \ esac; \ done; \ test $$has_opt = yes am__make_dryrun = (target_option=n; $(am__make_running_with_option)) am__make_keepgoing = (target_option=k; $(am__make_running_with_option)) pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

That original website is mirrored here, in the [doc/html](/doc/html/) directory. This update is a snapshot of the final version 3.1.0 of the codebase, and includes work from Dave Richards, providing a MSWindows-friendly C++ wrapper. Dave's work is in the [cgle-c++](cgle-c++) directory. GLE --- GLE is a library package of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. Generically, the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. GLE uses the GL or OpenGL(R) API's to perform the actual rendering. The demos use GLUT and require GLUT to be installed. ![img](/doc/html/basic.gif "Basic Cylinders") ![img](/doc/html/texscr.gif "Textured Screw") ![img](/doc/html/twist3.gif "Cut surface") Obtaining OpenGL ---------------- OpenGL is available on UNIX, Linux, Mac and Windows. Find more about OpenGL at https://www.opengl.org/ Obtaining GLUT -------------- The demos require that the GLUT windowing and utility library be installed. Most OpenGL distributions come with GLUT (I think). On Linux/Debian --------------- On modern Linux systems, skip the above, and instead, just say: ``` sudo apt-get install libgle3-dev ``` This will give you everything in this git repo, precompiled. If you want to compile from source, you will need this: ``` apt-get install libgl1-mesa-dev libxmu-dev libxi-dev freeglut3-dev ``` ![img](/doc/html/helix2.gif "Helix") ![img](/doc/html/helixtex.gif "Textured Helix") Compiling --------- GLE uses the standard GNU automake/autoconf build process, and thus should be portable to essentially all computing platforms. At the command line simply type `./configure` to set things up for your CPU & operating system. Then run `make` to compile. Finally, cd to the examples directory, and run the script `rundemo` to launch each of the demos in order (from most basic, to advanced). Use the left mouse button to move, the middle mouse button to access the pop-down menu. If `configure` fails, its probably because some library or another is missing. Look at the file 'config.log' to see what actually went wrong. In particular, pay attention to the short program at the end: trying to compile it by hand will give you a good idea on why it failed. ### Flags that can be supplied to `./configure`: `--enable-lenient-tess` If you have a tesselator that is happy with anything, including degenerate points, colinear segments, etc. then define this. Otherwise, don't specify this flag. Setting this flag provides a minor performance improvement. I beleive that the stock SGI tesselator is "lenient", despite explicit disclaimers in the documentation. (circa 1995). Early versions of the MesaGL tesselator are not at all forgiving of degenerate points. This resulted in frequent crashes and/or hangs. (circa 1997-2000). Recent versions (as of 2001) seem to work fine. `--disable-auto-texture` Disable texture mapping code. Disabling texture mapping may provide a very minor performance improvement. `--enable-irisgl` Compile for old IrisGL/GL-3.2 API. This used to work, but hasn't been tested in a long time. `--enable-debug` Will compile sources so printf routines will be called instead of OpenGL routines. Warning: this will generate a *lot* of output! ### Website Mirror More information about building, as well as this package, can be found in the mirror of the original website, in the [doc/html](https://github.com/linas/glextrusion/tree/master/doc/html/) directory. ![img](/doc/html/helix4.gif "Ribbon") ![img](/doc/html/shear.gif "Shearing") RedHat RPM's ------------ RedHat RPM's can be built using the `gle.spec` file. Python, SWIG ------------ Python bindings for gle can be found in the [/swig](swig) directory. Be sure to read the readme. Compiling for Windows ------------------------ To compile with Visual C++, just do the following: ``` cd src cl -c -DWIN32 -DOPENGL_10=1 *.c lib -out:gle.lib *.obj ``` Alternately, there are a set of Microsoft Visual Studio Project files in the directory [ms-visual-c](ms-visual-c) that should do the same thing. Running ------- Some of the example programs will hang or crash when run on older (pre-2001) versions of MesaGL/Linux. This was due to bugs in the MesaGL tesellator. Newer versions should work fine. gle-3.1.2/acconfig.h000066400000000000000000000016571446777505400142420ustar00rootroot00000000000000/********************************************************************\ * acconfig.h -- configuration defines for gle * * Copyright (C) 2000 Linas Vepstas (linas@linas.org) * \********************************************************************/ #ifndef __GLE_CONFIG_H__ #define __GLE_CONFIG_H__ /* Package name and version number */ #undef PACKAGE #undef VERSION /* Standard C headers present */ #undef STDC_HEADERS /* limits.h header present */ #undef HAVE_LIMITS_H /* Build for OpenGL by default, and not for old IrisGL aka GL 3.2 */ #define OPENGL_10 1 #undef GL_32 /* Disable debugging stuff (debugging replaces GL output with printfs) */ #undef DEBUG_OUTPUT /* Do we have a lenient tesselator? */ #undef LENIENT_TESSELATOR #define DELICATE_TESSELATOR 1 /* Enable texture mapping by default. */ #define AUTO_TEXTURE 1 /* assume a modern C compiler */ #undef FUNKY_C #endif gle-3.1.2/aclocal.m4000066400000000000000000001221241446777505400141510ustar00rootroot00000000000000# generated automatically by aclocal 1.16.3 -*- Autoconf -*- # Copyright (C) 1996-2020 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Introduction

This library is an adaptation of the Tubing and Extrusions library that comes as part of the GLUT download. That library's original author is Linas Vepstas. Linas has a web site dedicated to GLE at http://linas.org/gle/index.html. Further info is available in Copyright and License Info. Excerpts from Linas' original MAN documents are italicized like the one below.

The following is an excerpt from Linas' original gle documentation:


The most general extrusion supported by this library allows an arbitrary 2D contour to be swept around an arbitrary 3D path. A set of colors and affine matrices can be specified to go along with the 3D path. The colors are used to color along the path. The affine matrices are used to operate on the contour as it is swept along. If no affine matrices are specified, the contour is extruded using the mathematical concept of "parallel translation" or "Gaussian translation". That is, the contour is moved (and drawn) along the extrusion path in a "straight" manner. If there are affine matrices, they are applied to the contour at each extrusion segment before the segment is drawn.

The affine matrices allow work in a quasi-non-Euclidean space. They essentially allow the contour to be distorted as it is swept along. The allow the contour to be rotated, translated and rescaled as it is drawn. For example, a rescaling will turn a polycylinder into a poly-cone, since the circle that is being extruded is scaled to a different size at each extrusion vertex. A rotation allows the contour to be spun around while it is being extruded, thus for instance allowing drill-bit type shapes to be drawn. A translation allows the appearance of shearing in real space; that is, taking a contour and displacing it, without otherwise bending it. Note that the affines are 2x3 matrices, not 3x4 matrices, since they apply to the 2D contour as it is being extruded.

A "sweep" or "extrusion" is a 2D contour (polyline) that is swept or extruded along a 3D path (polyline). For example, sweeping a circle along a straight line will generate a cylinder. Sweeping a circle along a circular path will generate a doughnut (torus).

The library also includes a set of utility routines for drawing some of the more common extruded shapes: a polycylinder, a polycone, a generalized torus (circle swept along a helical path), a "helix" (arbitrary contour swept along a helical path) and a "lathe" (arbitrary contour swept along a helical path, with torsion used to keep the contour aligned).


This version of the gle library implements the class heirarchy depicted here.

GLE32 differs from Linas' original C library in that include all the original gle primitives, along with a couple that were presented in examples of the library's use - the screw, for instance. By placing most of the functional code into a single base class, most of the parameters from the drawing code function calls could be replaced with data members global to the class. In addition, I moved all the memory allocation possible into the object's constructors, reducing the amount of code necessary in the rendering loop, boosting performance. I also upgraded the tessellator code from OpenGL 1.0 compatible code to OpenGL 1.1, and using some code from one Linas' example programs, eliminated the need to specify normal vectors for the contour points.

The original library used glColor3f to optionally set individual color values at each point along the extrusion path. Getting color to change under lighting involved the use of glColorMaterial to link a set of material parameters to the glColor command. This implementation still supports that option, plus allows the user to more directly set the ambient, emmisive and diffuse material components through the use of a 'UseLitMaterial' member function.


The extruded objects are based on Linas' code. Generally speaking, they are created by specifying a) a cross-section pattern; and b) a 3-space coordinate array used to define a PolyLine that the extrusion will follow. The effect is like an OpenGL Play-Doh machine. The manner in which bends are made and ends terminated is controlled by Join Style settings. Various normal vector configurations allowing proper lighting effects may be specified with Vector Style constants. The textured drawing methods for each object can generate various configurations of texture coordinates; these are selected with the Texture Mode constants. The up direction of the cross section can be specified with LoadUpVector. Some classes expose the base class capability of applying an affine transformation matrix to the extrusion; these classes have a SetTForm function. An optional array of color values can be used when rendering the objects; it's use is controlled be the UseLitMaterial member function.

Definitions: * "Package" refers to the collection of files (in this directory and its subdirectories) distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. * "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder. * "Copyright Holder" is whoever is named in the copyright or copyrights for the package. * "You" is you, if you're thinking about copying or distributing this Package. * "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) * "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. 6. The graphic art and geometrical data supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Package. 7. C or perl subroutines supplied by you and linked into this Package shall not be considered part of this Package. 8. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission. 9.

Generically, the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. GLE uses the GL or OpenGL API's to perform the actual rendering. Keywords: graphics surface sweep tube extrude polycone polycylinder OpenGL Author: linas@linas.org (Linas Vepstas) Maintained-by: linas@linas.org (Linas Vepstas) Primary-site: 697k metalab.unc.edu pub/Linux/libs/X/gle-3.0.0.tar.gz Alternate-site: 485k tsx-11.mit.edu pub/linux/sources/libs/gle.2.2.7.tar.gz Original-site: 697k http://linas.org/gle/gle-3.0.0.tar.gz Platform: GLE is known to compile and run on the following: RS/6000 (AIX 3.2.5, AIX 4.1, with xlc and gcc, OpenGL LPP) Linux (Linux 1.x, 2.x with gcc and MesaGL) SGI (Irix 5.x) Reported to compile & run with Digital UNIX, HPUX, IBM OS/2, Microsoft NT Copying-policy: Freely distributable, AS-IS, no warrenty.

GLE Tubing and Extrusion Library
GLE, written by Linas Vepstas, is a library package of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. Generically, the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. OpenGL is used to perform the actual rendering. GLE is also included with the latest release of Mark Kilgard's GLUT toolkit.

GLE Build Notes & General Info

Background and Overview

The GLE Tubing and Extrusion Library is a graphics application programming interface (API). The library consists of a number of "C" language subroutines for drawing tubing and extrusions. The library is distributed in source code form, in a package that includes documentation, a VRML proposal, Makefiles, and full source code and header files. It uses the OpenGL (TM) programming API to perform the actual drawing of the tubing and extrusions.

GLE is known to run on UNIX(r) and UNIX-like operating systems such as Linux, AIX, IRIX, Ultrix and HPUX with OpenGL or Mesa. GLE is also known to run on OS/2 Warp.

A spec file is included for automatically building RedHat RPM's.

Build Notes

The GLE build system uses the GNU automake/autoconf tools. These tools should allow GLE to build cleanly on virtually all computing platforms.

To build the library, simply type configure at the command line to set things up for your CPU & operating system. Then run make to compile. Finally, cd to the examples directory, and run the shell script rundemo to launch each of the demos in order (from most basic, to advanced).

You may find the following configure flags useful:

--enable-lenient-tess
If you have a tesselator that is happy with anything, including degenerate points, collinear segments, etc. then define this. Otherwise, don't specify this flag. Setting this flag provides a minor performance improvement. I believe that the stock SGI tesselator is "lenient", despite explicit disclaimers in the documentation. (circa 1995). Early versions of the MesaGL tesselator are not at all forgiving of degenerate points. This resulted in frequent crashes and/or hangs. (circa 1997-2000). Recent versions (as of 2001) seem to work fine. If you have an old version of MesaGL, do not set --enable-lenient-tess

--disable-auto-texture
Disable texture mapping code. Disabling texture mapping may provide a very minor performance improvement.

--enable-irisgl
Compile for old IrisGL/GL-3.2 API. This used to work, but hasn't been tested in a long time.

--enable-debug
Will compile sources so printf routines will be called instead of OpenGL routines. Warning: this will generate a *lot* of output!

If you have difficulties... here are some notes:

IBM AIX, SGI Irix, HP and DEC Systems
There are no known compile or run time problems. If you have difficulty making on these systems, make sure that OpenGL and GLUT are present. (Note: the new automake/autoconf build process has *not* been tested on these systems.)

Linux Systems
Older MesaGL tesselator was prone to hangs and crashes. Recent (2001) versions seem to do just fine. There are currently no other known compile or runtime problems.

Windows NT/2000 and Windows 95/98
GLE will compile & run on these Microsoft systems under several different development environments. The subdirectory ms-visual-c contains project files. The README contains additional information.

Macintosh OS version 9
GLE has been reported to compile & run on this Apple operating system using the CodeWarrier development environment, once some 'standard' modifications are made. (??)

GL and OpenGL Libraries
The tubing and extrusion library can be compiled for GL 3.2 or for OpenGL. By default, the Makefile are configured for OpenGL. (Warning: the library has NOT been run on GL 3.2 in years, and so might be broken in minor ways. With tweaking, though it should work.)

Obtaining the GL, OpenGL and GLUT libraries
OpenGL is available on most UNIX(R) workstations, as well as OS/2(R) and Windows NT. Contact your workstation vendor for more information or visit the OpenGL Web Site (See also SGI's OpenGL site). GLE also works with Mesa, a public-domain OpenGL-like API. Mesa can be found at http://www.mesa3d.org/

The demos require that the GLUT windowing and utility library be installed. GLUT can be obtained at http://reality.sgi.com/opengl/glut3/

GLUT Libraries
The demos require the GLUT library and headers to be installed.

Compile time warnings
You may see some compile time warnings. Ignore these. These occur because not all compilers correctly handle doubly-index subscripts, and so the code does some funny business to get around this. To the best of my knowledge, the code still executes correctly despite these warnings. Note, however, that my efforts to eliminate these warning may result in code that old compilers will not be able to compile, or will compile but not execute correctly.

(In my humble opinion, the way in which the C/C++ language handles doubly, triply, etc. subscripted arrays is fundamentally broken. The syntax is not self-consistent. Many important constructs are undefined by ANSI-C (and C++). In the good old days, when most compilers were broken in this area anyway, you could happily work around this with single-index arrays and fancy address calculation. Now that compilers have been fixed, and, thanks to C++, strict-type-checking is all the rage, the fundamental short-comings of C/C++ in this area start becoming horribly apparent. To put it another way, I agonized over how subscripting should be handled, and what, if any new types needed to be introduced. Sadly, I was unable to design code that compiled on most compilers, AND not introduce new types, AND avoid strict-typechecking warning messages. Sadly, the result is a horrible mess. )

The Hard Facts

The GLE Tubing and Extrusion Library is a graphics application programming interface (API). The library consists of a number of "C" language subroutines for drawing tubing and extrusions. It is a very fast implementation of these shapes, outperforming all other implementations, most by orders of magnitude. The library is distributed in source code form, in a package that includes documentation, a VRML proposal, Makefiles, and full source code and header files. It uses the OpenGL (TM) programming API to perform the actual drawing of the tubing and extrusions.

GLE is designed for and maintained on the Linux operating system, and is known to run on other Unix operating systems such as AIX, IRIX, Ultrix and HPUX with OpenGL or Mesa. GLE is also known to run on IBM OS/2 Warp, Apple Macintosh OS9, and Microsoft Windows NT and has been used to develop screen-savers for some of these popular PC operating systems.

News: Alpha Blending/Transparency now supported by means of new *_c4f routines that allow RGBA values to be passed down into the API.

News: Dave Richards has created a set of MSWindows-specific C++ classes that are derived from gle. See the GLE32 site. (mirror)

News: There is now a mailing list to discuss gle: gle-discuss@lists.sourceforge.net. Subscribe by web or view the archives.

News: Version 3.0 is out, sporting an improved/simplified build system, which should make compiling this package a lot less confusing. Project has been moved to SourceForge, which means you can get live CVS, and should make it easier for folks to submit patches & participate in this project.

News: ShapeShifter is a re-write of the GLE library in Java. Available freely, under the 'Artistic License'.

News: OpenGL internals programmers & hardware developers, please read this.

News: Python bindings are shipped with this release. They were generated with a non-standard version of SWIG. There is also another (different) set of bindings for GLE that come standard with OpenGL at the PyOpenGL site. At this point, neither set should be considered to be more 'standard' than the other.

A Gentle Introduction

The libgle.a library contains a collection of routines for drawing sweeps and extrusions. A "sweep" or "extrusion" is a 2D contour (polyline) that is swept or extruded along a 3D path (polyline). For example, sweeping a circle along a straight line will generate a cylinder. Sweeping a circle along a circular path will generate a doughnut (torus).

The library also includes a set of utility routines for drawing some of the more common extruded shapes: a polycylinder, a polycone, a generalized torus (circle swept along a helical path), a "helix" (arbitrary contour swept along a helical path) and a "lathe" (arbitrary contour swept along a helical path, with torsion used to keep the contour aligned).

The most general extrusion supported by this library allows an arbitrary 2D contour to be swept around an arbitrary 3D path. A set of normal vectors can be specified to go along with the contour; the normal vectors determine the appearance of the contour when lighting is turned on. A set of colors and affine matrices can be specified to go along with the 3D path. The colors are used to color along the path. The affine matrices are used to operate on the contour as it is swept along. If no affine matrices are specified, the contour is extruded using the mathematical concept of "parallel translation" or "Gaussian translation". That is, the contour is moved (and drawn) along the extrusion path in a "straight" manner. If there are affine matrices, they are applied to the contour at each extrusion segment before the segment is drawn.

The affine matrices allow work in a quasi-non-Euclidean space. They essentially allow the contour to be distorted as it is swept along. The allow the contour to be rotated, translated and rescaled as it is drawn. For example, a rescaling will turn a polycylinder into a poly-cone, since the circle that is being extruded is scaled to a different size at each extrusion vertex. A rotation allows the contour to be spun around while it is being extruded, thus for instance allowing drill-bit type shapes to be drawn. A translation allows the appearance of shearing in real space; that is, taking a contour and displacing it, without otherwise bending it. Note that the affines are 2x3 matrices, not 3x4 matrices, since they apply to the 2D contour as it is being extruded.

Subroutine Descriptions

int gleGetJoinStyle (void); 
void gleSetJoinStyle (int style);	      /* bitwise OR of flags */
Query and Set the join style flags. This word is a bitwise OR of the flags described below.

Extrusion Join Styles

TUBE_JN_RAW
Draw polycylinders, polycones, extrusions, etc. with no special treatment of the extrusion ends.

TUBE_JN_ANGLE
Draw polycylinders, polycones, extrusions, etc. by extending the different segments until they butt into each other with an angular style.

TUBE_JN_CUT
Draw polycylinders, polycones, extrusions, etc. by joining together the different segments and slicing off the joint at half the angle between the segments. A cap is drawn. Note that the slicing plane runs through the origin of the contour coordinate system. Thus, the amount of slice can be varied by offsetting the contour with respect to the origin.

Note that when two segments meet at a shallow angle, the cut join style will potentially shave off a whole lot of the contour, leading to "surprising" results...

TUBE_JN_ROUND
Joints will be rounded. Strictly speaking, the part of the joint above the origin will be rounded. The part below the origin will come together in an angular join.

TUBE_JN_MASK
Mask bits. This can be used to mask off the bit field that defines the join style.

End Caps

TUBE_JN_CAP
If this is set, a cap will be drawn at each end of the extrusion.

Automatic Normal Vector Generation

TUBE_NORM_FACET
A normal vector is generated per facet. Useful for having an extrusion have a "faceted" look, such as when extruding a square -- each of the four sides of the square will look flat.

TUBE_NORM_EDGE
Normal vectors are generated so that they lie along edges. Useful for making angular things look rounded under lighting. For example, when extruding a hexagon and using this flag, the hexagonal extrusion will look (more like a) smooth perfectly round cylinder, rather than a six-sided shape.

TUBE_NORM_PATH_EDGE
Normal vectors are generated so that they both lie on edges, and so that they interpolate between neighboring segments. Useful for drawing "spaghetti" -- extrusions that follow a spline path. Because the spline path must be "tessellated" into small straight segments, each segment will look straight unless this flag is set.

TUBE_NORM_MASK
A mask useful for masking out the "norm" bits.

Closed or Open Contours

TUBE_CONTOUR_CLOSED
If this bit is set, the contour will be treated as a "closed" contour, where the last point connects back up to the first. It is useful to set this flag when drawing closed shapes (such as extruded cylinders, star-shapes, I-Beams, etc.) When drawing open extrusions (e.g. corrugated sheet metal), you DON'T want to set this flag.

Texture Routines

In addition to the default TexGen modes that are supplied by OpenGL, the tubing library also contains some of its own automatic texture coordinate generation routines. This is needed in order to be able to draw a texture that 'sticks' to the extruded surface. The GLE library supplies 12 different texture mapping modes; in addition, user-defined texture coord generation routines can be supplied. (See the pipeline documentation for details). GLE needs to specify these many routines, since no one method is appropriate for all shapes. The 'flat' texture modes are appropriate for flat, open surfaces. The 'cylinder' texture modes are appropriate for long spaghetti shapes. The 'sphere' modes are appropriate for ball-like surfaces of revolution. Use the 'vertex' versions of these routines if your surface is nearly isometric (i.e. when the distances between the points in the contour are roughly equal to the distances between these same points in final 3D shape.) Use the 'normal' versions of these routines when changes in the normal vector are a better indicator of the distance between points on the surface. (In the case of a cylinder, one should expect that 'vertex' and 'normal' texturing yield the same results.) The 'model' modes will in general pin the texture onto the surface, and so the surface wiggles, it will look like the texture is painted on. The non-model modes will use real-space coordinates, and so the texture may fit better on static, fixed shapes; however, if the shape wiggles, then the texture will squirm around on the surface. You'll need to pick an appropriate mode for your shape. If you're clever, then define your own. (and send me patches if possible).

To use GLE texture mapping with the extrusion library, one must remember to "do the obvious":

  • Enable texture mapping through OpenGL
  • Define and load (lmdef/lmbind) a texture
  • If you enable gleTextures, then disable glTexgGen 
gleTextureMode(int mode);   /* bitwise OR of flags */
This routine can be used to set the type of automatic texture coordinate generation to be used. The argument should be a bitwise-OR of any of the following flags:
GLE_TEXTURE_ENABLE
If this bit is set, then texturing is enabled. If this bit is NOT set, then automatic texture coordinate generation is disabled.

The way in which the automatic texture coordinate generation occurs is determined by one of the following flags. One and only one of these should be selected at a time. These tokens are enumerants, not bit-flags.
GLE_TEXTURE_VERTEX_FLAT
Uses the vertexes "x" coordinate as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate.

GLE_TEXTURE_NORMAL_FLAT
Uses the normal vector's "x" coordinate as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate.

GLE_TEXTURE_VERTEX_CYL
Uses u = phi/(2*pi) = arctan (vy/vx)/(2*pi) as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. In the above equation, "vx" and "vy" stand for the vertex's x and y coordinates.

GLE_TEXTURE_NORMAL_CYL
Uses u = phi/(2*pi) = arctan (ny/nx)/(2*pi) as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. In the above equation, "nx" and "ny" stand for the normal's x and y coordinates.

GLE_TEXTURE_VERTEX_SPH
Uses u = phi/(2*pi) = arctan (vy/vx)/(2*pi) as the texture "u" coordinate, and v = theta/pi = (1.0 - arccos(vz))/pi as the texture "v" coordinate. In the above equation, "vx","vy" and "vz" stand for the vertex's x, y and z coordinates.

GLE_TEXTURE_NORMAL_SPH
Uses u = phi/(2*pi) = arctan (ny/nx)/(2*pi) as the texture "u" coordinate, and v = theta/pi = (1.0 - arccos(nz))/pi as the texture "v" coordinate. In the above equation, "nx","ny" and "nz" stand for the normal's x, y and z coordinates.

These define texture mapping modes that are very similar to those described above, except that the untransformed vertices and/or normals are used. As a result, textures tends to stick to the extrusion according to the extrusions local surface coordinates rather than according to real-space coordinates. This will in general provide the correct style of texture mapping when affine transforms are being applied to the contour, since the coordinates used are those prior to the affine transform.


How it Works

To best understand how to use the above functions, it is best to understand how the tubing is actually drawn. Let us start by defining some terms. The tubing library "extrudes" a "contour" along a "path". The contour is a 2D polyline. The path is a 3D polyline. We use the word "segment" to refer to a straight-line segment of the path polyline. We also interchangeably use the word "segment" to stand for the section of the extrusion that lies along a path segment.

The tubing library draws segments one at a time. It uses glPushmatrix() and glPopmatrix() to orient each segment along the negative z-axis. The segment starts at z=0 and ends at some negative z-value (equal to the length of the segment). The segment is then drawn by calling glVertex3f() (and glNormal3F()) by drawing the 2D contour at z=0 and again at z=-len. (Of course, if the join style is one of the fancy ones, then the end-points are trimmed in a variety of ways, and do not land exactly on z=0, or z=-len, but they do come close). Note that glBegin() and glEnd() are called around each segment. (Note also that additional glBegins/Ends may be called to draw end-caps or filleting triangles for the more complex join styles.)

The obvious way to automatically generate textures is to warp the glVertex() and glNormal() functions, and compute texture coordinates based on the 3-space vertex and normal coordinates. This is essentially what the tubing code does, except that it passes some extra parameters. The glBegin calls are wrapped, and the integer segment number and the floating-point length of the segment are passed in. By knowing the segment number, and the segment length, the texture coordinates can be adjusted. Knowing the length allows the length to be accumulated, so that a texture is applied lengthwise along the extrusion. It is this accumulated length that is used in the FLAT and CYL mapping modes.

For each vertex, not only are the vertex x,y,z coordinates available, but so is a contour vertex counter indicating which contour vertex this corresponds to. There is also a flag indicating whether the vertex corresponds to a front or back vertex (i.e. a z=0 or z=-len vertex). Again, this info can be used to avoid confusion when drawing the more complex join styles.


Hints, Tips and Techniques

  • Hint: Confused? RUN THE DEMOS! The best way to understand what all the different texture modes are doing is to see them in action.
  • Hint: The texture matrix can be used to your advantage! That is, you can use glMatrixMode(GL_TEXTURE) to control how textures are mapped to the surface. In particular, you may/will want to use it to to rescale the V coordinate.
  • The origin of the contour will in general change the vertex x's and y's, thus changing the texture coordinates.
  • The contour "up" vector will NOT influence the texture coordinates.
  • For the FLAT and CYL modes, the accumulated length really is the accumulated length of the segments in modeling coordinates. Unless the extrusion is very small, this length will probably be much larger than 1.0, and so the resulting texture coordinate will wrap. You will generally want to rescale the "V" coordinate to make the texture map fit.
  • If the texture is "swimming" around on the surface in an undesired way, try using the "MODEL" version of the texture generation flag.
  • Typically, you will NOT want to use the "SPH" versions of the texture generation engine unless you really, really have an extrusion for which spherical coordinates are appropriate. Most uses of extrusions are best handled with the "FLAT" and "CYL" generation methods.
  • User-defined texture generation callbacks are not currently implemented, but these should be very, very easy to hack in as desired. It should be easy to let your imagination run wild in here. Look at texgen.c -- what needs to be done should be obvious, I hope. When in doubt, experiment.

Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc.

The color array may be NULL. If NULL, the current color is used. If not NULL, the glColor3f() routine is used to set the color; therefore, specifying the glColorMaterial() subroutine before this primitive can be used to set diffuse, specular, ambient, etc. colors. The glePolyCylinder_c4f() routine calls glColor4f() instead, thus allowing alpha-blending (transparency) to be performed.

By default, the cross-section of the cylinder is drawn as a 20-sided polygon. This number can be changed using the gleSetNumSides() routine.

                   gleDouble radius_array[]); /* cone radii at polyline verts */
Draw polycone, specified as a polyline with radii.

Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc.

By default, the cross-section of the cylinder is drawn as a 20-sided polygon. This number can be changed using the gleSetNumSides() routine. 

 int gleGetNumSides(void);
 void gleSetNumSides(int slices);
Query and set the GLE cylinder and cone roundness. When GLE draws a cylinder or a cone, it approximates the circular cross-section with a polygon (of 20 sides by default). These subroutines can be used to change the default number of sides in this cross-section. A smaller number of sides can typically be drawn much faster, at the loss of some visual accuracy. Increasing the number of sides to more than 20 will typically have no noticeable visual effect.

Extrude arbitrary 2D contour along arbitrary 3D path. The argument "contour" specifies the 2D contour to be extruded, while the argument "point_array" specifies the path along which to extrude. The vector "up" defines the orientation of the contour y-axis in real 3D space.

Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc.

The normal array may be NULL. If it is, normal vectors will NOT be automatically generated, and the object will look terrible when lit.

                gleDouble twist_array[]);   /* contour twists (in degrees) */
Extrude arbitrary 2D contour along arbitrary 3D path, specifying local rotations (twists). As the contour is extruded, it will be twisted by the amount specified in the array "twist_array". The angles are measured in degrees, and the rotation is about the origin of the contour coordinate system.

The argument "contour" specifies the 2D contour to be extruded, while the argument "point_array" specifies the path along which to extrude. The vector "up" defines the orientation of the contour y-axis in real 3D space.

Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc.

                gleDouble xform_array[][2][3]);   /* 2D contour xforms */
Extrude arbitrary 2D contour along arbitrary 3D path, specifying local affine transformations. As the contour is extruded, the affine will be applied to the points in the contour.

The argument "contour" specifies the 2D contour to be extruded, while the argument "point_array" specifies the path along which to extrude. The vector "up" defines the orientation of the contour y-axis in real 3D space.

Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc.

             gleDouble startTheta,	/* start angle in x-y plane */
             gleDouble sweepTheta);	/* degrees to spiral around */
Sweep an arbitrary contour along a helical path.

The axis of the helix lies along the modeling coordinate z-axis.

An affine transform can be applied as the contour is swept. For most ordinary usage, the affines should be given as NULL.

The "startXform[][]" is an affine matrix applied to the contour to deform the contour. Thus, "startXform" of the form 

|  cos     sin    0   |
|  -sin    cos    0   |
will rotate the contour (in the plane of the contour), while 
|  1    0    tx   |
|  0    1    ty   |
will translate the contour, and 
|  sx    0    0   |
|  0    sy    0   |
scales along the two axes of the contour. In particular, note that 
|  1    0    0   |
|  0    1    0   |
is the identity matrix.

The "dXformdTheta[][]" is a differential affine matrix that is integrated while the contour is extruded. Note that this affine matrix lives in the tangent space, and so it should have the form of a generator. Thus, dx/dt's of the form 

|  0     r    0   |
|  -r    0    0   |
rotate the the contour as it is extruded (r == 0 implies no rotation, r == 2*PI implies that the contour is rotated once, etc.), while 
|  0    0    tx   |
|  0    0    ty   |
translates the contour, and 
|  sx    0    0   |
|  0    sy    0   |
scales it. In particular, note that 
|  0    0    0   |
|  0    0    0   |
is the identity matrix -- i.e. the derivatives are zero, and therefore the integral is a constant.

Sweep an arbitrary contour along a helical path. The sweep will be performed as a shear along the z-axis, so that the orientation of the contour is displaced, rather than translated, as the contour is swept.

The axis of the helix lies along the modeling coordinate z-axis.

An affine transform can be applied as the contour is swept. For most ordinary usage, the affines should be given as NULL.

             gleDouble twist);          /* number of rotations */
Draws screw-type shapes. Takes a contour, and extrudes it along the z-axis, from a start z value of startz to an end z-value of endz. During the extrusion, it will spin the contour along the contour origin by twist degrees.

VRML Tubing Extension Proposal

This page describes a proposed extension to VRML to handle extruded surfaces. An extruded surface is a surface that is generated by moving a 2D curve along a 3D path. Surfaces of revolution, sweeps, and polycylinders are all examples of extruded surfaces. The pictures below show examples of extrusions.

Extrusions are interesting because they potentially provide for a compact representation of surface data. A swept surface of m points by n points requires O(m x n) bytes of data to represent it as a quadrilateral mesh. The same surface requires only O(m + n) bytes when represented as a sweep.

Extrusions are also interesting because they allow a designer to specify complex shapes in a simple manner.

This proposal is based on the API provided through the freely available tubing and extrusion library. The tubing and extrusion library is a C language API that renders extrusions through OpenGL. It automatically generates the surface, normals for lighting, and texture coordinates.

The Proposal

Below follows the proposal. It is preliminary. Alternate suggestions are welcome. You may find this spec to be "under-specified". For immediate questions, consult the tubing/extrusion API documentation and examples. The spec will be updated in time.

(Warning ... this spec is or may soon be superceeded by a similar but different spec in the Moving Worlds proposal. If in doubt, code to the Moving Worlds spec.)

Basically, I cannot make this spec official; only the Moving Worlds folks have the power to write the official spec.

The Extrusion Node

The Extrusion node defines the basic extrusion. The other nodes defined below are either special cases of the extrusion node, or generalizations. 
PROTO Extrusion [             # indicates that this is an extrusion node
   field MFVec2f crssSection  # polyline cross-section to be extruded
   field MFVec2f normals      # normals to the contour
   field MFVec3f spine        # 3D polyline extrusion path / spine
   field MFVec3f pathColors   # colors to be applied along the path.
   field MFVec3f pathXforms   # list of 2 by 3 affine matrices
   field SFVec3f up [0 1 0]   # y-axis of contour in 3-space
   field SFVec3f frontCap     # perpendicular to the front cap.
   field SFVec3f backCap      # perpendicular to the back cap.
   field SFEnum joinstyle  [ANGLE]  # the join style
   field SFBool drawCap    [TRUE]   # if true, draw the end caps
   field SFEnum normStyle  [PATH_EDGE] # how normals are used.
   field SFEnum texGen     [OFF]    # texture coordinate generation style
}
The contour field defines a 2D polyline that represents the cross-section of the extrusion. The contour will be swept along the 3D polyline path (spine) to define the surface. The contour field must be present, otherwise, an extrusion cannot be drawn.

The contourNormals field defines an array of 2D normals to the contour. The 2D normals will be extruded along the polyline path to generate the 3D normals needed for lighting. If the contourNormals field is not present, then facet normals will be computed and used.

The path defines the 3D polyline path (spine) along which the polyline is extruded. The path field MUST be present, otherwise, an extrusion cannot be drawn.

The pathColors field defines colors which will be used to color the vertices along the path. The colors will be used as the diffuse component of the material. If this field is missing, the current material will be used.

The pathXforms field defines a series of 2 by 3 affine matrices that are to be applied to the contour at each path vertex. If this field is missing, then unit matrices are assumed.

The up field defines the orientation of the contour's y-axis in 3D space. That is, the contour is interpreted in a 2D coordinate system whose y-axis is "up", and whose x-axis is defined as the cross product of up and the first segment of path. If this field is missing, the value is taken to be [0 1 0].

The frontCap field defines the orientation of the front end-cap of the extrusion. It is used, in conjunction with the join style, to define how the end of the extrusion should be trimmed. If this field is missing, then the frontCap vector is taken to be parallel to the first segment of the path. That is, the front cap is drawn perpendicular to the first segment of the "path".

The backCap field defines the orientation of the back end-cap of the extrusion. It is used, in conjunction with the join style, to define how the end of the extrusion should be trimmed. If this field is missing, then the backCap vector is taken to be parallel to the last segment of the path. That is, the back cap is drawn perpendicular to the last segment of the "path".

The joinstyle node defines how segments are to be joined. There are four possible values: 

RAW       # ends are perpendicular to segments
ANGLE     # segments join together.
CUT       # joins are trimmed.
ROUND     # joins are rounded.

The drawCap field indicates whether the end caps should be drawn.

The normStyle field indicates how normals should be handled. It can take on one of four values: 

FACET          # one normal per facet
CONTOUR_FACET  # normals along the edge of the path.
PATH_FACET     # normals along the edge of the contour
EDGE           # normals along the edge of both contour and path.

The texGen field indicates whether and how texture coordinates are generated for the extrusion It can take on one of 13 values: 

OFF                 # texture generation disabled.
VERTEX_FLAT         # See API documentation
NORMAL_FLAT
VERTEX_CYL
NORMAL_CYL
VERTEX_SPH
NORMAL_SPH
MODEL_VERTEX_FLAT
MODEL_NORMAL_FLAT
MODEL_VERTEX_CYL
MODEL_NORMAL_CYL
MODEL_VERTEX_SPH
MODEL_NORMAL_SPH

PolyCylinder

The PolyCylinder is a special case of the extrusion, where the extruded contour is a circle. 
PROTO PolyCylinder {                # indicates that this is a polycylinder
   field MFVec3f path               # 3D polyline extrusion path
   field MFVec3f pathColors         # colors to be applied along the path.
   field MFVec3f pathXforms         # list of 2 by 3 affine matrices
   field SFVec3f frontCap           # orientation of the front cap.
   field SFVec3f backCap            # orientation of the back cap.
   field SFEnum joinstyle ANGLE     # the join style
   field SFBool drawCap   TRUE      # if true, draw the end cap
   field SFEnum normStyle PATH_EDGE # how normals are used.
   field SFEnum texGen    OFF       # texture coordinate generation
}

PolyCone

The PolyCone is a special case of the PolyCylinder, where all of the transforms specify a radius. That is, all of the affine transforms are of the form 
r  0  0
0  r  0
That is, the contour is scaled uniformly by the radius at each vertex. 
PROTO PolyCone {             # indicates that this is an extrusion node
   field MFVec3f path               # 3D polyline extrusion path
   field MFVec3f pathColors         # colors to be applied along the path.
   field MFFloat radii              # radius at each vertex
   field SFVec3f frontCap           # orientation of the front cap.
   field SFVec3f backCap            # orientation of the back cap.
   field SFEnum joinstyle ANGLE     # the join style
   field SFBool drawCap   TRUE      # if true, draw the end cap
   field SFEnum normStyle PATH_EDGE # how normals are used.
   field SFEnum texGen    OFF       # texture coordinate generation
}
That's all for now, although clearly some of the other API routines might be interesting ...

Competing Proposals

The current Moving Worlds Specification proposal for VRML 2.0 contains a similar node, called the GeneralCylinder. Below, we provide a brief glossary relating that proposal to this.
spine
We call this the path. We do not define a default, although if we had, it would follow the GL conventions: [0 0 0 0 0 -1], that is, the cross section x and y are screen-aligned, and the extrusion path lies along the negative z-axis, pointing into the screen. This is the canonic system used in the implementation.

crossSection
We call this the contour. Same concept, fewer letters. Our 2D contours live in a 2D x-y space, which, by default, is parallel to the 3D x-y plane. For the GeneralCylinder proposal, the 2D x-y plane is parallel to the 3D X-Z plane.

sides
In our proposal, the sides are always drawn.

beginCap, endCap
In our proposal, these two have been merged into one flag -- either both caps are drawn, or both are not. Our proposal could be generalized in this way ... not a problem, if this is perceived as important.

ccw, solid, convex
The Moving Worlds proposal lacks detail in this area.

creaseAngle
Our proposal does not contain this, primarily because the sample implementation does not support this. Adding this could add some complexity to the implementation. Furthermore, there are really two crease angles: that in the contour (cross-section), and that in the path (spine). These two should be logically kept separates becomes clear if one thinks of how surfaces of revolution are generated.

The effect of crease angles can be emulated by drawing the extrusion in parts, with different normal-generation styles for each part.

width, twist
This is a slightly less general version of our pathXforms field. If I have read the specification correctly, then our 2D affine xform equals 
         |   width*cos(twist)     -width*sin(twist)     0   |
         |   width*sin(twist)      width*cos(twist)     0   |
We have found the full form useful when defining screw-shapes, that is, surfaces of revolution that are offset as they are swept. The third fields (0 in the above), are critical for achieving the shearing motion when sweeping the curve.

The affine-matrix form is admittedly confusing to the general public. Therefore, it might make sense to define a node of the form 

PROTO GeneralCylinder {             # indicates that this is an extrusion node
   field MFVec3f path               # 3D polyline extrusion path
   field MFVec3f pathColors         # colors to be applied along the path.
   field MFFloat width              # scale cross section
   field MFFloat twist              # rotate cross section
   field MFFloat tx              # translate cross section in x direction
   field MFFloat ty              # translate cross section in y direction
   field SFVec3f frontCap           # orientation of the front cap.
   field SFVec3f backCap            # orientation of the back cap.
   field SFEnum joinstyle ANGLE     # the join style
   field SFBool drawCap   TRUE      # if true, draw the end cap
   field SFEnum normStyle PATH_EDGE # how normals are used.
   field SFEnum texGen    OFF       # texture coordinate generation
}
where the affine is given by 
         |   width*cos(twist)     -width*sin(twist)     tx   |
         |   width*sin(twist)      width*cos(twist)     ty   |
It is not clear that this less-general form easier or better than the fully general form.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'. Add to this or # override it after sourcing this library to reflect the full set of # options your script accepts. usage_message="\ --debug enable verbose shell tracing -W, --warnings=CATEGORY report the warnings falling in CATEGORY [all] -v, --verbose verbosely report processing --version print version information and exit -h, --help print short or long help message and exit " # Additional text appended to 'usage_message' in response to '--help'. long_help_message=" Warning categories include: 'all' show all warnings 'none' turn off all the warnings 'error' warnings are treated as fatal errors" # Help message printed before fatal option parsing errors. fatal_help="Try '\$progname --help' for more information." ## ------------------------- ## ## Hook function management. ## ## ------------------------- ## # This section contains functions for adding, removing, and running hooks # to the main code.

Definitions: * "Package" refers to the collection of files (in this directory and its subdirectories) distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. * "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder. * "Copyright Holder" is whoever is named in the copyright or copyrights for the package. * "You" is you, if you're thinking about copying or distributing this Package. * "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) * "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. 6. The graphic art and geometrical data supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Package. 7.

The library consists of a number of "C" language subroutines for drawing tubing and extrusions. The library is distributed in source code form, in a package that includes documentation, a VRML proposal, Makefiles, and full source code and header files. It uses the OpenGL (TM) programming API to perform the actual drawing of the tubing and extrusions. A "sweep" or "extrusion" is a 2D contour (polyline) that is swept or extruded along a 3D path (polyline). For example, sweeping a circle along a straight line will generate a cylinder. Sweeping a circle along a circular path will generate a doughnut (torus). The library also includes a set of utility routines for drawing some of the more common extruded shapes: a polycylinder, a polycone, a generalized torus (circle swept along a helical path), a "helix" (arbitrary contour swept along a helical path) and a "lathe" (arbitrary contour swept along a helical path, with torsion used to keep the contour aligned). The most general extrusion supported by this library allows an arbitrary 2D contour to be swept around an arbitrary 3D path. A set of normal vectors can be specified to go along with the contour; the normal vectors determine the appearance of the contour when lighting is turned on. A set of colors and affine matrices can be specified to go along with the 3D path. The colors are used to color along the path. The affine matrices are used to operate on the contour as it is swept along. If no affine matrices are specified, the contour is extruded using the mathematical concept of "parallel translation" or "Gaussian translation". That is, the contour is moved (and drawn) along the extrusion path in a "straight" manner. If there are affine matrices, they are applied to the contour at each extrusion segment before the segment is drawn. The affine matrices allow work in a quasi-non-Euclidean space. They essentially allow the contour to be distorted as it is swept along. The allow the contour to be rotated, translated and rescaled as it is drawn. For example, a rescaling will turn a polycylinder into a poly-cone, since the circle that is being extruded is scaled to a different size at each extrusion vertex. A rotation allows the contour to be spun around while it is being extruded, thus for instance allowing drill-bit type shapes to be drawn. A translation allows the appearance of shearing in real space; that is, taking a contour and displacing it, without otherwise bending it. Note that the affines are 2x3 matrices, not 3x4 matrices, since they apply to the 2D contour as it is being extruded. .SH WEB SITE http://linas.org/gle/index.html .SH SEE ALSO gleExtrusion, gleHelicoid, gleLathe, glePolyCone, glePolyCylinder, gleScrew, gleSetJoinStyle, gleSpiral, gleSuperExtrusion, gleTextureMode, gleToroid, gleTwistExtrusion, gleTwistExtrusion, gleSuperExtrusion .SH AUTHOR Linas Vepstas (linas@linas.org) gle-3.1.2/man/gleExtrusion.man000066400000000000000000000034631446777505400162550ustar00rootroot00000000000000.\" .\" GLE Tubing & Extrusions Library Documentation .\" .TH gleExtrusion 3GLE "3.0" "GLE" "GLE" .SH NAME gleExtrusion - Extrude arbitrary 2D contour along arbitrary 3D path. .SH SYNTAX .nf .LP void gleExtrusion (int ncp, gleDouble contour[][2], gleDouble cont_normal[][2], gleDouble up[3], int npoints, gleDouble point_array[][3], float color_array[][3]); .fi .SH ARGUMENTS .IP \fIncp\fP 1i number of contour points .IP \fIcontour\fP 1i 2D contour .IP \fIcont_normal\fP 1i 2D contour normals .IP \fIup\fP 1i up vector for contour .IP \fInpoints\fP 1i numpoints in poly-line .IP \fIpoint_array\fP 1i polyline vertices .IP \fIcolor_array\fP 1i colors at polyline verts .SH DESCRIPTION Extrude arbitrary 2D contour along arbitrary 3D path. The argument "contour" specifies the 2D contour to be extruded, while the argument "point_array" specifies the path along which to extrude. The vector "up" defines the orientation of the contour y-axis in real 3D space. Note that neither the very first segment, nor the very last segment are drawn. The first and last segments serve only to define the angle of the join at the very ends of the polyline. Thus, to draw one segment, three must be specified. To draw two segments, four must be specified, etc. The normal array may be NULL. If it is, normal vectors will NOT be automatically generated, and the object will look terrible when lit. The color array may be NULL. If NULL, the current color is used. If not NULL, the glColor3f() routine is used to set the color; therefore, specifying the glColorMaterial() subroutine before this primitive can be used to set diffuse, specular, ambient, etc. colors. .SH SEE ALSO gleTwistExtrusion, gleSuperExtrusion .SH AUTHOR Linas Vepstas (linas@linas.org) gle-3.1.2/man/gleHelicoid.man000066400000000000000000000023531446777505400157720ustar00rootroot00000000000000.\" .\" GLE Tubing & Extrusions Library Documentation .\" .TH gleHelicoid 3GLE "3.0" "GLE" "GLE" .SH NAME gleHelicoid - Generalized torus, spiral with circle contour. .SH SYNTAX .nf .LP void gleHelicoid (gleDouble rToroid, gleDouble up[3], gleDouble startRadius, gleDouble drdTheta, gleDouble startZ, gleDouble dzdTheta, gleDouble startXform[2][3], gleDouble dXformdTheta[2][3], gleDouble startTheta, gleDouble sweepTheta); .fi .SH ARGUMENTS .IP \fIrToroid\fP 1i circle contour (torus) radius .IP \fIstartRadius\fP 1i spiral starts in x-y plane .IP \fIdrdTheta\fP 1i change in radius per revolution .IP \fIstartZ\fP 1i starting z value .IP \fIdzdTheta\fP 1i change in Z per revolution .IP \fIstartXform\fP 1i starting contour affine transformation .IP \fIdXformdTheta\fP 1i tangent change xform per revolution .IP \fIstartTheta\fP 1i start angle in x-y plane .IP \fIsweepTheta\fP 1i degrees to spiral around .SH DESCRIPTION Generalized Torus.

This word is a bitwise OR of the flags described below. The initial join style is TUBE_JN_ANGLE | TUBE_JN_CAP | TUBE_NORM_FACET. .B "Extrusion Join Styles" .IP \fBTUBE_JN_RAW\fP Draw polycylinders, polycones, extrusions, etc. with no special treatment of the extrusion ends. .IP \fBTUBE_JN_ANGLE\fP Draw polycylinders, polycones, extrusions, etc. by extending the different segments until they butt into each other with an angular style. .IP \fBTUBE_JN_CUT\fP Draw polycylinders, polycones, extrusions, etc. by joining together the different segments and slicing off the joint at half the angle between the segments. A cap is drawn. Note that the slicing plane runs through the origin of the contour coordinate system. Thus, the amount of slice can be varied by offsetting the contour with respect to the origin. Note that when two segments meet at a shallow angle, the cut join style will potentially shave off a whole lot of the contour, leading to "surprising" results... .IP \fBTUBE_JN_ROUND\fP Joints will be rounded. Strictly speaking, the part of the joint above the origin will be rounded. The part below the origin will come together in an angular join. .IP \fBTUBE_JN_MASK\fP Mask bits.

Useful for having an extrusion have a "faceted" look, such as when extruding a square -- each of the four sides of the square will look flat. .IP \fBTUBE_NORM_EDGE\fP Normal vectors are generated so that they lie along edges. Useful for making angular things look rounded under lighting. For example, when extruding a hexagon and using this flag, the hexagonal extrusion will look (more like a) smooth perfectly round cylinder, rather than a six-sided shape. .IP \fBTUBE_NORM_PATH_EDGE\fP Normal vectors are generated so that they both lie on edges, and so that they interpolate between neighboring segments. Useful for drawing "spaghetti" -- extrusions that follow a spline path. Because the spline path must be "tessellated" into small straight segments, each segment will look straight unless this flag is set. .IP \fBTUBE_NORM_MASK\fP A mask useful for masking out the "norm" bits. .B "Closed or Open Contours" .IP \fBTUBE_CONTOUR_CLOSED\fP If this bit is set, the contour will be treated as a "closed" contour, where the last point connects back up to the first. It is useful to set this flag when drawing closed shapes (such as extruded cylinders, star-shapes, I-Beams, etc. When drawing open extrusions (e.g. corrugated sheet metal), you DON'T want to set this flag. .SH BUGS Multiple threads using GLE share a single global join style (although this should be easily fixable because GLE does use a centralized graphics context). .SH SEE ALSO gleExtrusion, gleTextureMode .SH AUTHOR Linas Vepstas (linas@linas.org) gle-3.1.2/man/gleSetNumSides.man000066400000000000000000000020541446777505400164530ustar00rootroot00000000000000.\" .\" GLE Tubing & Extrusions Library Documentation .\" .TH gleSetNumSides 3GLE "3.0" "GLE" "GLE" .SH NAME gleSetNumSides, gleGetNumSides - Query and Set the cylinder roundness. .SH SYNTAX .nf .LP void gleSetNumSides (int nslices); int gleGetNumSides (void); .fi .SH ARGUMENTS .IP \fInslices\fP 1i positive integer number of slices .SH DESCRIPTION Query and set the GLE cylinder and cone roundness.

The axis of the helix lies along the modeling coordinate z-axis. An affine transform can be applied as the contour is swept. For most ordinary usage, the affines should be given as NULL. The "startXform[][]" is an affine matrix applied to the contour to deform the contour. Thus, "startXform" of the form | cos sin 0 | | -sin cos 0 | will rotate the contour (in the plane of the contour), while | 1 0 tx | | 0 1 ty | will translate the contour, and | sx 0 0 | | 0 sy 0 | scales along the two axes of the contour. In particular, note that | 1 0 0 | | 0 1 0 | is the identity matrix. The "dXformdTheta[][]" is a differential affine matrix that is integrated while the contour is extruded. Note that this affine matrix lives in the tangent space, and so it should have the form of a generator. Thus, dx/dt's of the form | 0 r 0 | | -r 0 0 | rotate the the contour as it is extruded (r == 0 implies no rotation, r == 2*PI implies that the contour is rotated once, etc.), while | 0 0 tx | | 0 0 ty | translates the contour, and | sx 0 0 | | 0 sy 0 | scales it. In particular, note that | 0 0 0 | | 0 0 0 | is the identity matrix -- i.e. the derivatives are zero, and therefore the integral is a constant. .SH SEE ALSO gleLathe .SH AUTHOR Linas Vepstas (linas@linas.org) gle-3.1.2/man/gleSuperExtrusion.man000066400000000000000000000040731446777505400172720ustar00rootroot00000000000000.\" .\" GLE Tubing & Extrusions Library Documentation .\" .TH gleSuperExtrusion 3GLE "3.0" "GLE" "GLE" .SH NAME gleSuperExtrusion - Extrude arbitrary 2D contour along arbitrary 3D path, specifying local affine transformations. .SH SYNTAX .nf .LP void gleSuperExtrusion (int ncp, gleDouble contour[][2], gleDouble cont_normal[][2], gleDouble up[3], int npoints, gleDouble point_array[][3], float color_array[][3], gleDouble xform_array[][2][3]); .fi .SH ARGUMENTS .IP \fIncp\fP 1i number of contour points .IP \fIcontour\fP 1i 2D contour .IP \fIcont_normal\fP 1i 2D contour normals .IP \fIup\fP 1i up vector for contour .IP \fInpoints\fP 1i numpoints in poly-line .IP \fIpoint_array\fP 1i polyline vertices .IP \fIcolor_array\fP 1i colors at polyline verts .IP \fIxform_array\fP 1i 2D contour affine transforms .SH DESCRIPTION Extrude arbitrary 2D contour along arbitrary 3D path, specifying local affine transformations.

In addition, user-defined texture coord generation routines can be supplied. To use texture mapping with the extrusion library, one must remember to "do the obvious": .IP Enable texture mapping through OpenGL .IP Define and load (glTexImage2D/glBindTexture) a texture .IP If using the routine below, then disable glTexgGen .LP gleTextureMode can be used to set the type of automatic texture coordinate generation to be used. The argument should be a bitwise-OR of any of the following flags: .IP \fBGLE_TEXTURE_ENABLE\fP If this bit is set, then texturing is enabled. If this bit is NOT set, then automatic texture coordinate generation is disabled. .LP The way in which the automatic texture coordinate generation occurs is determined by one of the following flags. One and only one of these should be selected at a time. These tokens are enumerants, not bit-flags. .IP \fBGLE_TEXTURE_VERTEX_FLAT\fP Uses the vertexes "x" coordinate as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. .IP \fBGLE_TEXTURE_NORMAL_FLAT\fP Uses the normal vector's "x" coordinate as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. .IP \fBGLE_TEXTURE_VERTEX_CYL\fP Uses u = phi/(2*pi) = arctan (vy/vx)/(2*pi) as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. In the above equation, "vx" and "vy" stand for the vertex's x and y coordinates. .IP \fBGLE_TEXTURE_NORMAL_CYL\fP Uses u = phi/(2*pi) = arctan (ny/nx)/(2*pi) as the texture "u" coordinate, and the accumulated segment length as the "v" coordinate. In the above equation, "nx" and "ny" stand for the normal's x and y coordinates. .IP \fBGLE_TEXTURE_VERTEX_SPH\fP Uses u = phi/(2*pi) = arctan (vy/vx)/(2*pi) as the texture "u" coordinate, and v = theta/pi = (1.0 - arccos(vz))/pi as the texture "v" coordinate. In the above equation, "vx","vy" and "vz" stand for the vertex's x, y and z coordinates. .IP \fBGLE_TEXTURE_NORMAL_SPH\fP Uses u = phi/(2*pi) = arctan (ny/nx)/(2*pi) as the texture "u" coordinate, and v = theta/pi = (1.0 - arccos(nz))/pi as the texture "v" coordinate. In the above equation, "nx","ny" and "nz" stand for the normal's x, y and z coordinates. .IP \fBGLE_TEXTURE_VERTEX_MODEL_FLAT\fP .IP \fBGLE_TEXTURE_NORMAL_MODEL_FLAT\fP .IP \fBGLE_TEXTURE_VERTEX_MODEL_CYL\fP .IP \fBGLE_TEXTURE_NORMAL_MODEL_CYL\fP .IP \fBGLE_TEXTURE_VERTEX_MODEL_SPH\fP .IP \fBGLE_TEXTURE_NORMAL_MODEL_SPH\fP These define texture mapping modes that are very similar to those described above, except that the untransformed vertices and/or normals are used. As a result, textures tends to stick to the extrusion according to the extrusions local surface coordinates rather than according to real-space coordinates. This will in general provide the correct style of texture mapping when affine transforms are being applied to the contour, since the coordinates used are those prior to the affine transform. .SH OPERATION To best understand how to use the above functions, it is best to understand how the tubing is actually drawn. Let us start by defining some terms. The tubing library "extrudes" a "contour" along a "path". The contour is a 2D polyline. The path is a 3D polyline. We use the word "segment" to refer to a straight-line segment of the path polyline. We also interchangeably use the word "segment" to stand for the section of the extrusion that lies along a path segment. The tubing library draws segments one at a time. It uses glPushmatrix() and glPopmatrix() to orient each segment along the negative z-axis. The segment starts at z=0 and ends at some negative z-value (equal to the length of the segment). The segment is then drawn by calling glVertex3f() (and glNormal3F()) by drawing the 2D contour at z=0 and again at z=-len. (Of course, if the join style is one of the fancy ones, then the end-points are trimmed in a variety of ways, and do not land exactly on z=0, or z=-len, but they do come close). Note that glBegin() and glEnd() are called around each segment. (Note also that additional glBegins/Ends may be called to draw end-caps or filleting triangles for the more complex join styles.) The obvious way to automatically generate textures is to warp the glVertex() and glNormal() functions, and compute texture coordinates based on the 3-space vertex and normal coordinates. This is essentially what the tubing code does, except that it passes some extra parameters. The glBegin calls are wrapped, and the integer segment number and the floating-point length of the segment are passed in. By knowing the segment number, and the segment length, the texture coordinates can be adjusted. Knowing the length allows the length to be accumulated, so that a texture is applied lengthwise along the extrusion. It is this accumulated length that is used in the FLAT and CYL mapping modes. For each vertex, not only are the vertex x,y,z coordinates available, but so is a contour vertex counter indicating which contour vertex this corresponds to. There is also a flag indicating whether the vertex corresponds to a front or back vertex (i.e. a z=0 or z=-len vertex). Again, this info can be used to avoid confusion when drawing the more complex join styles. .SH HINTS Here are a few hints, tips, and techniques: .IP o Hint: Confused? RUN THE DEMOS! The best way to understand what all the different texture modes are doing is to see them in action. .IP o Hint: The texture matrix can be used to your advantage! That is, you can use glMatrixMode(GL_TEXTURE) to control how textures are mapped to the surface. In particular, you may/will want to use it to to rescale the V coordinate. .IP o The origin of the contour will in general change the vertex x's and y's, thus changing the texture coordinates. .IP o The contour "up" vector will NOT influence the texture coordinates. .IP o For the FLAT and CYL modes, the accumulated length really is the accumulated length of the segments in modeling coordinates. Unless the extrusion is very small, this length will probably be much larger than 1.0, and so the resulting texture coordinate will wrap. You will generally want to rescale the "V" coordinate to make the texture map fit. .IP o If the texture is "swimming" around on the surface in an undesired way, try using the "MODEL" version of the texture generation flag. .IP o Typically, you will NOT want to use the "SPH" versions of the texture generation engine unless you really, really have an extrusion for which spherical coordinates are appropriate. Most uses of extrusions are best handled with the "FLAT" and "CYL" generation methods. .IP o User-defined texture generation callbacks are not currently implemented, but these should be very, very easy to hack in as desired. It should be easy to let your imagination run wild in here. Look at texgen.c -- what needs to be done should be obvious, I hope. When in doubt, experiment. .SH BUGS Multiple threads using GLE share a single texture mode. .SH SEE ALSO gleExtrusion, gleSetJoinStyle .SH AUTHOR Linas Vepstas (linas@linas.org) gle-3.1.2/man/gleToroid.man000066400000000000000000000023221446777505400155060ustar00rootroot00000000000000.\" .\" GLE Tubing & Extrusions Library Documentation .\" .TH gleToroid 3GLE "3.0" "GLE" "GLE" .SH NAME gleToroid - Generalized torus, lathe with circle contour. .SH SYNTAX .nf .LP void gleToroid (gleDouble rToroid, gleDouble up[3], gleDouble startRadius, gleDouble drdTheta, gleDouble startZ, gleDouble dzdTheta, gleDouble startXform[2][3], gleDouble dXformdTheta[2][3], gleDouble startTheta, gleDouble sweepTheta); .fi .SH ARGUMENTS .IP \fIrToroid\fP 1i circle contour (torus) radius .IP \fIstartRadius\fP 1i spiral starts in x-y plane .IP \fIdrdTheta\fP 1i change in radius per revolution .IP \fIstartZ\fP 1i starting z value .IP \fIdzdTheta\fP 1i change in Z per revolution .IP \fIstartXform\fP 1i starting contour affine transformation .IP \fIdXformdTheta\fP 1i tangent change xform per revolution .IP \fIstartTheta\fP 1i start angle in x-y plane .IP \fIsweepTheta\fP 1i degrees to spiral around .SH DESCRIPTION Generalized Torus.

Built libraries will be located in the lib-folder. The Debug-version is named gled.lib and the release-version gle.lib. Both are compiled using the run-time libraries "Debug Multithreaded DLL" and "Multithreaded DLL". When the library is built an include/GL directory will be created and the gle.h file from the src directory will be copied into it.

will make no visual difference when join style is CAP. ------------------------------------------------------------------- Work left to be done: --------------------- 1) cylnder/cone tesselation should be adaptive ... 2) round-join tessleation should be adaptive. 4) Need to interpolate normal vectors for fillet triangles. Not doing this results in visual artifacts in certain cases. 5) Need to interpolate colors for fillet triangles (not doing this leaves potential for visual artifacts, although I haven't yet seen any.) 6) allow user to install callbacks for V3F, etc (similar to callbacks in gluTess). 7) given i, j point, return actual x,y,z, coords. 10) Some end-caps are concave ... OpenGL GLU utilioty does a sloppy job of concave polygons ... so some of the figures look bad. What to do about this? 11) The ex_raw.c module would probably execute ()some tens of cycles) faster if it had a ex_angle type interface for the normal vector gorp. 13) Testing problem -- I'm worried that contours with only two points will croak the "cut_join" style code. Be sure to test this. 17) polycone raw endcaps are flashing colors -- some kind of bug. 18) Write the @#$%^&*( documentation. ------------------------------------------------------------------- FIXED: ------ 3) round join style not doing backfacing properly at this moment. FIXED 3 June 1993 9) extrusions with more than 64 vertices in the contour may overflow the hardware ... our bgn...end constructs may have to check for such cases ... (for h/w with the 256 vertex limit only). A: Punt. Most hardware today doesn't have this limit anymore. 12) Another significant optimization that can be performed is to convert many of the routines to work along z-axis only. One reason this was not done right off the bat was for readability and maintainability. However, once the code becomes stable, this may be a good idea. (What I mean here is that many routines, such as "intersect()" and "CUTTING_PLANE()" perform operations on x and y coordinates. These are needed for a GENERAL "intersect()" routine; however, the way that they are used below does not require that generality (since all of the drawing occurs parallel to the z-axis). With a little bit of careful thought, the x and y computations could be ripped out). A: But this will not work if there are twists in the contour, since now, extrusions do NOT run parallel to z-axis, and the x,y coordinates are non-trivial. 14) Q: convert extrude.c to work in a bgn/end style of collecting up data? (how to handle 2x3 affine matricies in the bgn/end style?) A: Don't do it. It would make it hard to deal with the per-vertex affine matrices. A much better idea is to implement a C++ object which has a begin-end interface for each poly extrusion object. 15) convert to OpenGL Done. However, see note 10 above. 16) add texture demos that demo the texutre hack. ------------------------------------------------------------------- gle-3.1.2/src/copy.h000066400000000000000000000006451446777505400142260ustar00rootroot00000000000000 /* * * Written By Linas Vepstas November 1991 */ #define COPY_THREE_WORDS(A,B) { \ struct three_words { long a, b, c, }; \ *(struct three_words *) (A) = *(struct three_words *) (B); \ } #define COPY_FOUR_WORDS(A,B) { \ struct four_words { long a, b, c, d, }; \ *(struct four_words *) (A) = *(struct four_words *) (B); \ } /* ============================================================= */ gle-3.1.2/src/ex_alpha.c000066400000000000000000000037441446777505400150330ustar00rootroot00000000000000/* * FILE: * ex_alpha.c * * FUNCTION: * Framework file to auto-generate subroutines with different * signature for color argument.

It is this: * * This module attempts to correctly treat contour normal vectors * by applying the inverse transpose of the 2D contour affine * transformation to the 2D contour normals. This is perfectly correct, * when applied to the "raw" join style. However, if the affine transform * has a strong rotational component, AND the join style is angle or * cut, then the normal vectors would continue to rotate as the * intersect point is extrapolated. * * The extrapolation of the inverse-transpose matrix to the intersection * point is not done. This would appear to be overkill for most * situations. The viewer might possibly detect an artifact of the * failure to do this correction IF all three of the following criteria * were met: * 1) The affine xform has a strong rotational component, * 2) The angle between two succesive segments is sharp (greater than 15 or * 30 degrees). * 3) The join style is angle or cut. * * However, I beleive that it is highly unlikely that the viewer will * detect any artifacts. The reason I beleive this is that a strong * rotational component will twist a segment so strongly that the more * visible artifact will be that a segment is composed of triangle strips. * As the user attempts to minimize the tesselation artifacts by shortening * segments, then the rotational component will decrease in proportion, * and the lighting artifact will fall away. * * To summarize, there is a slight inexactness in this code.

The problem presented here * is that the tolerance could run out before single-precision ran * out, and so the CAD packages would perceive this as a "bug". * One alternative is to fiddle around & try to tighten the tolerance. * However, the right alternative is to code the graphics pipeline in * double-precision (and tighten the tolerance). * * By the way, note that Degernate Tolerance is a "dimensionless" * quantitiy -- it has no units -- it does not measure feet, inches, * millimeters or pixels.

One set is included in this directory. Another set comes by default with the OpenGL Python wrappers at http://pyopengl.sourceforge.net/ Neither set should be considered more 'official' or 'standard' than the other: use the one that is most convenient for you. Python and SWIG --------------- The Simple Wrapper Generator (SWIG) can be used to create python bindings for gle functions. Normally, a small definition file, run through swig, is enough. This directory contains the definition and autogenerated code for a special, non-generally available version of SWIG. It should work; however, it is unmaintainable. If you are willing to maintain this code, let me (linas@linas.org) know. See email below: > From: "Michel Sanner" > To: linas@linas.org > Subject: resending -- Re: Gle wrapper source] > > Hi Linas, > > In fact I used a "special" version of SWIG (1.2a1) which David Baisley gave me > a few yars ago when I was working on typemaps for Numeric arrays. This version > provides pre-processing capabilities which are necessary for the typemaps I > used in gle.i. Unfortunately, these capabilities never made it into SWIG (at > least not up to now) and therefore noone out there would have a SWIG capable of > generating the wrapper code from that interface. > > The pre-processing capabilities are used to generate dimension arguments from > the shape of numeric arrays.
