Vertex and Pixel shader instructions sets

Vertex and Pixel shader instructions sets

Secondly, does anyone have a link to the complete instruction sets for vertex and pixel shaders? Seems most place google brings me is "shader tutorial, by franky" which is always lacking of low-level detail.

ARB_vertex_program tutorial Another one (pdf) ARB_fragment_program spec ARB_vertex_program spec I think the lack of info on the old assembly shaders is because they were just extensions that were added to the OpenGL 2.0 spec as GLSL. Take a look at Nvidia's Cg (C for graphics). Looks a bit easier to pickup than GLSL, and isn't limited to just OpenGL. This post has been edited by Tom9729: 24 Jun, 2009 - 10:30 AM
