Thanks for you help! I've been developing with Cg for a while now. I've just recently purchased the OpenGL Shading Language book and I'm on the hunt for examples. nVIDIA has numerous and very helpful Cg downloads, toolkits, utilities, etc. Does 3DLabs provide anything? I've been to their web site and thus far have found nothing.
Also, I've not been very impressed with the book examples and color plates. I've not seen any Fresnel examples ... couldn't find a refract function, etc. But, maybe I've overlooked things. I am just starting out.
