I'd like to learn who to programm cg and shader, cause I need to implement some wind sway for my trees I'm currently working on. So I tried Tutorial 47 to learn the basics about vertex shaders. Unfortunatly the programm doesn't run correctly on my Radeon 9700 Mobility. Whenever I start the .exe or compile the project all I see is a flat green grid - no wave, no motion. I've installed cg 1.3 and I got no errors during compilation. I tried ist on Geforce TI 4200 and it works without any problems. Someone has hat the same problem or a clue whats going wrong? I'm new to cg and shader programming, so it could be a very simple mistake... [Edited by - SKerner on June 6, 2005 5:57:43 AM]
