I have just started learning OpenGL off of NeHe, and I know DX8 with C++, But will anyone tell me if the really cool things of DX8 like Vertex/Pixel Shaders are available in OpenGL, the reason I ask is that Ive never seen OpenGL documentation or tutorials on the 2 subjects, Thanks Alot in advance [edited by - rickwi22 on April 30, 2002 8:58:08 PM]

I think vertex shaders are the only thing that OpenGL CANT do. Although there are a lot of other things that OpenGL CAN do that DirectX can''t.

OpenGL and DX8 have the same functionality when it comes to the topic at hand:

OpenGL Vertex Program == DX8 Vertex Shader
OpenGL Register Combiners & Texture Shaders == DX8 Pixel Shaders

In fact, Vertex Programs and Vertex Shaders have the same set of 17 basic opcodes (Just not named exactly the same).

You just need to use nVidia Extensions to get at VPs.
