   CGGL vs FFP
  I'd like to use vertex program to do VertexBlends(in Skinned Animation),and I'm new to CG.I think I should do something like cgGLBindProgram...the problem is can I use CG & FFP simutaneously in one program?say,can I use CG in VertexBlends,but FFP in something like terrain rendering?   
  The simple answer is yes you can use shaders and non shaders powered graphics in the same application, though not for the same object unless you want to multipass render or re-implement the whole FFP in CG (though that's not very FFP ....). Mearly unbind the shader, and opengl will switch back to the fixed functin pipeline.GOCP;  thank you very much.GOCP:GLSL vs. CG,which one is better?   ;  they are same , no diffrenet between them only the coding style and CG works on  NVIDIA cards and GLSL work on all cards that support ogl2.0+;  CG isn't just Nvidia, it shuold run on ATI cards as well. I switched from CG to GLSL as I work only in Opengl and found it cleaner to work with. Have a search of the forums, lots of threads discussing when one if more apporpriate than the other.I'd go GLSL if you're starting out and don't need DirectX support.GOCP
