View Full Version : GL_EXT_Cg_shader
06-01-2004, 04:39 AM
It seems that new Nvidia GL driver can eat plain
Cg code using GLSL extensions. I'v just tested simple Cg shader in ShaderDesigned and it works !!!
Even more... I can access to all GLSL matrices from Cg code to avoid boring glTrackMatrix.
Anyone have more info about this?
btw.. Im using FW 61.32 on FX5900XT

I know that it's an old topic but nVidia just released this information.
Do you know something more about this extension? Am I able to use it with NV2x CG fragment shaders?

If driver ext string reports EXT_Cg_shader you can use it. But, older cards doesn't support fragment programs, so you are limited only for vertex programs. Even more, I think that position invariance doesn't work well on non-FX hardware, ie.. if you want multipass then forget fixed funcion pipeline and do it via vertex shaders.
