| | '''OpenGL extension SGIX.shadow |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.SGIX.shadow to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension defines two new operations to be performed on texture |
| | values before they are passed on to the filtering subsystem. These |
| | operations perform either a <= or >= test on the value from texture |
| | memory and the iterated R value, and return 1.0 or 0.0 if the test |
| | passes or fails, respectively. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/SGIX/shadow.txt |
