OpenGL.GL.NV.light_max_exponent

OpenGL extension NV.light_max_exponent

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

Overview (from the spec)

Default OpenGL does not permit a shininess or spot exponent over 128.0. This extension permits implementations to support and advertise a maximum shininess and spot exponent beyond 128.0.

Note that extremely high exponents for shininess and/or spot light cutoff will require sufficiently high tessellation for acceptable lighting results.

Paul Deifenbach's thesis suggests that higher exponents are necessary to approximate BRDFs with per-vertex ligthing and multiple passes.
