OpenGL.GL.SGIS.fog_function

OpenGL extension SGIS.fog_function

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

Overview (from the spec)

This extension allows to define application-specific fog blend-factor function. Function is defined by the set of the "control" points and should be monotonic. Each control point represented as a pair of the eye-space distance value and corresponding value of the fog blending factor. The minimum number of control points is one. The maximum number is implementation dependent.

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