| '''OpenGL extension EXT.index_func | |
| This module customises the behaviour of the | |
| OpenGL.raw.GL.EXT.index_func to provide a more | |
| Python-friendly API | |
| Overview (from the spec) | |
| This extension provides a way to discard fragments when a comparison | |
| between the fragment's index value and a reference index fails. This | |
| may be used similarly to the alpha test which is available in RGBA mode. | |
| The official definition of this extension is available here: | |
| http://www.opengl.org/registry/specs/EXT/index_func.txt | |
