| | '''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: |
