| '''OpenGL extension SGIX.pixel_texture |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.SGIX.pixel_texture to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows the color components of pixel groups to be used as |
| texture coordinates, effectively converting a color image into a texture |
| coordinate image. Because texture mapping is essentially a |
| multidimensional table lookup, this conversion supports multidimensional |
| color lookups for images. Such multidimensional lookups can be used to |
| implement very accurate color space conversions. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/SGIX/pixel_texture.txt |
