OpenGL extension AMD.conservative_depth
This module customises the behaviour of the OpenGL.raw.GL.AMD.conservative_depth to provide a more Python-friendly API
Overview (from the spec)
There is a common optimization for hardware accelerated implementation of OpenGL which relies on an early depth test to be run before the fragment shader so that the shader evaluation can be skipped if the fragment ends up being discarded because it is occluded.
This optimization does not affect the final rendering, and is typically possible when the fragment does not change the depth programmatically. (i.e.: it does not write to the built-in gl_FragDepth output). There are, however a class of operations on the depth in the shader which could still be performed while allowing the early depth test to operate.
This extension allows the application to pass enough information to the GL implementation to activate such optimizations safely.
The official definition of this extension is available here:
