[Mesa3d-dev] NV_vertex_program parser / code generator

[Jeff E. <je...@us...>]

After reading about NV_vertex_program, an OpenGL extension which is
supported in hardware on the GeForce3 in Windows, I became interested
in implementing a software version of the feature.  NVidia has recently
documented this feature in a comprehensive pdf document of OpenGL
extensions.

I have a (somewhat tested) parser for the language and a (nearly untested)
3DNow!/gas code generator for the vertex program language (one
instruction unimplemented, two instructions partially implemented,
the rest implemented but I've never actually executed the code, just
eyeballed it) This code is written in Python, and is thus far from likely
to be suitable for inclusion in its current form.

I have implemented none of the added functions in Mesa, since I am
unfamiliar with the rendering pipeline.  Right now all that exists is a
commandline program which takes the vertex program source and emits
assembly code suitable for feeding to GNU as.  

If you're interested in having a gander at my code, just drop me a line.
It's a ~20k tarball file which should run on any system with Python 1.5
or newer installed.

I'd also like to hear what thoughts people have on the NV_vertex_program
extension, on this list if it's considered topical, otherwise in private
e-mail.

Have a nice day,
Jeff
