OpenGL.GL.EXT.light_texture

OpenGL extension EXT.light_texture

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

Overview (from the spec)

This extension defines a general mechanism for substituting the fragment color computed during texture environment processing in place of other fragment attributes such as the fragment normal, or as sources for some of the computations in the fragment processing pipeline, for example as material or light parameters in the fragment lighting computations.
