OpenGL.GL.ARB.shadow

OpenGL extension ARB.shadow

This module customises the behaviour of the OpenGL.raw.GL.ARB.shadow to provide a more Python-friendly API

Overview (from the spec)

This extension clarifies the GL_SGIX_shadow extension.

This extension supports comparing the texture R coordinate to a depth texture value in order to produce a boolean texture value. This can be used to implement shadow maps.

The extension is written in generic terms such that other texture comparison modes can be accommodated in the future.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/ARB/shadow.txt
