OpenGL.GL.NV.texgen_reflection

OpenGL extension NV.texgen_reflection

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

Overview (from the spec)

This extension provides two new texture coordinate generation modes that are useful texture-based lighting and environment mapping. The reflection map mode generates texture coordinates (s,t,r) matching the vertex's eye-space reflection vector. The reflection map mode is useful for environment mapping without the singularity inherent in sphere mapping. The normal map mode generates texture coordinates (s,t,r) matching the vertex's transformed eye-space normal. The normal map mode is useful for sophisticated cube map texturing-based diffuse lighting models.
