| '''OpenGL extension EXT.index_material |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.EXT.index_material to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extends color index lighting to include a way for the current |
| index to contribute to the color index produced by lighting. This |
| works much like ColorMaterial does for RGBA lighting by allowing |
| one or more color index material properties to be attached to the |
| current index. |
| |
| The color index lighting formula is also modified so that the lit |
| color index may be bitwise shifted in order to allow greater control |
| when using lighting and fog together in color index mode. |
| |
| The official definition of this extension is available here: |
