[Mesa3d-dev] GLSL support in drivers

2007-03-26 Thread Brian Paul
Here's a quick little list of things that'll need to be addressed in the DRI drivers if we want to update them to run shading language programs. The drivers that currently support GL_ARB_vertex/fragment_program are the likely candidates. 1. New instructions The shading language has conditiona
