| | '''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 |
