Sorry. What I am referring to as the "synthetic environment" is the three dimensional image that you appear to be inside of as you play. Every time you move the computer needs to re-create the image from your location and the direction you are looking. That means vector arithmetic that rotates every item in the 3-D database usually using 4 x 4 matrix multiplications for each point in the image. It is a whole lot of arithmetic that has to worry about which parts of the scene are obscured by others and shadows due to the lighting. The more you move around using the mouse or game console to make the moves the more the computer has to do and it can be a whole lot. The computation gets so intense that it is often unloaded to something like an Nvidia graphics board that's made for the purpose. -- --> A fair tax is one that you pay but I don't <-- -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
