| | '''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 |
