**HELP** Does anyone know the logic behind a Chromakey operation??? In other words if I have two source pixel sets: (R1,G1,B1) and (R2,G2,B2) and image two is being 'CHROMAKEYED' BEHINF image 1, What is the logic required to produce my destination pixel??? (Rd,Gd,Bd). If anyone knows, please help..this is driving me nutzoid!!! Oh, last question..is it possible to do this in 3DS R3 VP (or anywhere else for that matter??). Thanks.
