vertex shaders

i have a redeon 9000 mobilty card and it doesn’t support any pixel shader extentions in opengl so i assume it’s not opengl 2.0. Any good sites on this topic would be nice or tutorils that explain how to use them.

I mean help on vertex shaders EXT. thank u

check if it supports
ARB_vertex_program (it should)
that will give you control over vertex processing too. just not as “nice” to use since its ASM language.

there should be plenty tutorials around for it

another alternative is using “Cg” it can compile to ARB_vertex_program and gives you advantage of having easier readable code.
Cg does run on ATI (just CgFX is broken a bit)

Here is a good glsl intro to vertex/fragment shaders using OpenGL, this should get you started
