'''OpenGL extension ARB.vertex_blend
This module customises the behaviour of the
OpenGL.raw.GL.ARB.vertex_blend to provide a more
Python-friendly API
Overview (from the spec)
This extension provides the ability to replace the single
modelview transformation with a set of n vertex units. (Where
n is constrained to an implementation defined maximum.) Each
unit has its own modelview transform matrix. For each unit,
there is a current weight associated with the vertex. When
this extension is enabled the vertices are transformed by
the modelview matrices of all of the enabled units. Afterward,
these results are scaled by the weights for the respective
units and then summed to create the eye-space vertex. A
similar procedure is followed for the normals, except they
are transformed by the inverse transpose of the modelview
matrices.
This extension is an orthoganalized version of functionality
already provided by other 3D graphics API's.
The official definition of this extension is available here:
