'''OpenGL extension NV.texgen_emboss
This module customises the behaviour of the
OpenGL.raw.GL.NV.texgen_emboss to provide a more
Python-friendly API
Overview (from the spec)
This extension provides a new texture coordinate generation mode
suitable for multitexture-based embossing (or bump mapping) effects.
Given two texture units, this extension generates the texture
coordinates of a second texture unit (an odd-numbered texture unit)
as a perturbation of a first texture unit (an even-numbered texture
unit one less than the second texture unit). The perturbation is
based on the normal, tangent, and light vectors. The normal vector
is supplied by glNormal; the light vector is supplied as a direction
vector to a specified OpenGL light's position; and the tanget
vector is supplied by the second texture unit's current texture
coordinate. The perturbation is also scaled by program-supplied
scaling constants.
If both texture units are bound to the same texture representing a
height field, by subtracting the difference between the resulting two
filtered texels, programs can achieve a per-pixel embossing effect.
The official definition of this extension is available here:
