| '''OpenGL extension EXT.fog_coord |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.EXT.fog_coord to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows specifying an explicit per-vertex fog |
| coordinate to be used in fog computations, rather than using a |
| fragment depth-based fog equation. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/EXT/fog_coord.txt |
