GLU ES - GLU 1.3 port for OpenGL ES

For a long time I was looking for a library capable of triangulating self-intersecting polygons or splitting them into simple polygons . In the end, I settled on the libtess of the GLU ES - in my case it is more convenient to connect with the mercurial subrepos a complete thirdparty library than roughly ruining and copying a piece of source code.



The GLU ES is the complete (as opposed to iGLU ) GLU 1.3 port under OpenGL ES. The porting was done by Mikhail Gorchak, for which he thanks a lot!



The library is available under the SGI FREE SOFTWARE LICENSE B license .

The library includes:

1. Matrix operations: gluLookAt, gluPerspective, etc.
2. Utilities for generating MIP-textures: gluScaleImage, gluBuild {1,2,3} DMipmaps, gluBuild {1,2,3} DMipmapLevels.
3. In a military manner, a universal API for triangulating polygons, which, among other things, makes it possible to implement Boolean operations on polygons.
4. Geometrical drawing utility utilities are gluSphere, gluCylinder, gluDisk, gluPartialDisk.
5. API for triangulating or directly drawing NURBS surfaces.
6. A small but pleasant trifle in the form of gluErrorString.

Unfortunately, the version on Google Code does not contain project files for building a project under iOS. Therefore, I forked the project and slightly modified it with a file. Fork is available on bitbucket . Screenshots of test applications are here , and the illustrated instructions for setting up a project are here .



I plan to infuse my changes into the main branch, but so far I have not managed to get in touch with Mikhail.
