'''OpenGL extension EXT.compiled_vertex_array
This module customises the behaviour of the
OpenGL.raw.GL.EXT.compiled_vertex_array to provide a more
Python-friendly API
Overview (from the spec)
This extension defines an interface which allows static vertex array
data to be cached or pre-compiled for more efficient rendering. This
is useful for implementations which can cache the transformed results
of array data for reuse by several DrawArrays, ArrayElement, or
DrawElements commands. It is also useful for implementations which
can transfer array data to fast memory for more efficient processing.
For example, rendering an M by N mesh of quadrilaterals can be
accomplished by setting up vertex arrays containing all of the
vertexes in the mesh and issuing M DrawElements commands each of
which operate on 2 * N vertexes. Each DrawElements command after
the first will share N vertexes with the preceding DrawElements
command. If the vertex array data is locked while the DrawElements
commands are executed, then OpenGL may be able to transform each
of these shared vertexes just once.
The official definition of this extension is available here:
