Hi everybody, I run a display routine with a vertex shader with Cg in OpenGL, the first time through (first frame of the display) it runs well (although the CPU part takes way too long, but that's another issue). The second frame, when I call cgGLBindProgram(v_thesis_prog); CheckCgError(); The program detects and prints the following error on the console: CG ERROR : An unsupported GL extension was required to perform this operation. I've been basing my code to tie in with the shader on Cg samples that don't require GL extensions and that run well in my computer, and I've included everything I've seen they include in these programs. Any suggestions or comments would be greatly appreciated. Thank you in advance.
