OpenGL extension NV.vertex_program3
This module customises the behaviour of the OpenGL.raw.GL.NV.vertex_program3 to provide a more Python-friendly API
Overview (from the spec)
This extension, like the NV_vertex_program2_option extension, provides additional vertex program functionality to extend the standard ARB_vertex_program language and execution environment. ARB programs wishing to use this added functionality need only add:
to the beginning of their vertex programs.
New functionality provided by this extension, above and beyond that already provided by NV_vertex_program2_option extension, includes:
texture lookups in vertex programs,
ability to push and pop address registers on the stack,
address register-relative addressing for vertex attribute and result arrays, and
a second four-component condition code.
