Hello all, I hope i have put this in the right forum... I was wondering, as a beginner in graphics programming... Those programmable pipelines... I know how to setup a vertex/pixel shader, but how can i make use of the multiple programmable pipelines?? My radeon 9800 pro has 4 of them, the new X800 has 6(vertex that is). How should i see this? Setting up 4 vertex shaders, setting 4 streams... and they starting working in parallel? Or will the 4 pipelines be used for the same geometry i send to the video card working with the same shader? I am a bit confused here, maybey someone can clear this up for me

You''re probably thinking of texturing units, in which case it''s the video card''s job to deal with it, not yours.

Well,

I think i found the answer somewhere in an ATI document... I should see it as a SIMD(Single Instruction Multiple Data). So, if there are 4 vertex pipelines, there will be 4 vertex shaders running, all the same, parallel. This means no worries for me about multiple pipelines
