A note on Cg

skiritis · 2005-07-05T16:48:53

I started reading shaders and Cg recently and i want to get some things clear bout pixel shader languages. Well, i own an Ati radeon 9800Pro, Cg is developed by nVidia and it seems that programmes written with Cg don't run on my ati card. Is this for real? Is Cg supposed to work on nVidia cards only? And what about HLSL and GLSL? If the above really is true and if i want to make wertex and pixel shading programmes that can run on all cards should i study GLSL and leave Cg? I really need some help here on these matter in which i'm new. Thanx. --- The big brother is watching you ---
