'''OpenGL extension NV.gpu_program4
This module customises the behaviour of the
OpenGL.raw.GL.NV.gpu_program4 to provide a more
Python-friendly API
Overview (from the spec)
This specification documents the common instruction set and basic
functionality provided by NVIDIA's 4th generation of assembly instruction
sets supporting programmable graphics pipeline stages.
The instruction set builds upon the basic framework provided by the
ARB_vertex_program and ARB_fragment_program extensions to expose
considerably more capable hardware. In addition to new capabilities for
vertex and fragment programs, this extension provides a new program type
(geometry programs) further described in the NV_geometry_program4
specification.
NV_gpu_program4 provides a unified instruction set -- all instruction set
features are available for all program types, except for a small number of
features that make sense only for a specific program type. It provides
fully capable signed and unsigned integer data types, along with a set of
arithmetic, logical, and data type conversion instructions capable of
operating on integers. It also provides a uniform set of structured
branching constructs (if tests, loops, and subroutines) that fully support
run-time condition testing.
This extension provides several new texture mapping capabilities. Shadow
cube maps are supported, where cube map faces can encode depth values.
Texture lookup instructions can include an immediate texel offset, which
can assist in advanced filtering. New instructions are provided to fetch
a single texel by address in a texture map (TXF) and query the size of a
specified texture level (TXQ).
By and large, vertex and fragment programs written to ARB_vertex_program
and ARB_fragment_program can be ported directly by simply changing the
program header from "!!ARBvp1.0" or "!!ARBfp1.0" to "!!NVvp4.0" or
"!!NVfp4.0", and then modifying the code to take advantage of the expanded
feature set. There are a small number of areas where this extension is
not a functional superset of previous vertex program extensions, which are
documented in this specification.
The official definition of this extension is available here:
