ARB_vertex_program

Is there a tutorial on this subject? So far I’ve read the GDC presentation and found it easy to setup. However, when I tried to expirement with the asm code, I keep on getting errors. I’ve tried to read the VP specification but ended up getting confused on how to use the instruction. The specification talks about how each instruction work, but it does not show any working examples.

Any info on how to use the assembly language would be great.

There are demos at nvidia and ati developer sites, some of which include source code.
I’ve also submitted one for NeHe Productions at http://nehe.gamedev.net/data/downloads/download.asp?letter=C
This is for Cel Shading and includes full source code and a complete walkthrough of the vertex program.
