| '''OpenGL extension ARB.depth_texture |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ARB.depth_texture to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This is a clarification of the GL_SGIX_depth_texture extension. The |
| original overview follows: |
| |
| This extension defines a new depth texture format. An important |
| application of depth texture images is shadow casting, but separating |
| this from the shadow extension allows for the potential use of depth |
| textures in other applications such as image-based rendering or |
| displacement mapping. This extension does not define new depth-texture |
| environment functions, such as filtering or applying the depth values |
| computed from a texture but leaves this to other extensions, such as |
| the shadow extension. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/ARB/depth_texture.txt |
