| | '''OpenGL extension SGIX.depth_texture |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.SGIX.depth_texture to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | 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/SGIX/depth_texture.txt |
