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:
