Abstract
CURRENT 3-D ANIMATION TECHNIQUES INVOLVES SIMPLE SHOWING SEPARATELY PREPARED IMAGES IN A SEQUENCE. THESE TECHNIQUES ARE SOMETIMES CALLED REPEAT-STATIC TECHNIQUES BECAUSE THEY MAKE NO USE OF THE SIMILARITY BETWEEN THE SUCCESSIVE IMAGES IN THE PREPARATION OF THE IMAGES. FOR REALISTIC ANIMATION REQUIRING THOUSANDS OF FRAMES, THE COMPUTATIONAL COST CAN BE PROHIBITIVE, AND THE TURN-AROUND TIME UNACCEPTABLE. IN THIS PROPOSAL, WE DESCRIBE HOW FRAME-TO-FRAME COHERENCE CAN BE USED TO DRASTICALLY REDUCE THE IMAGE PREPARATION TIME AND COST. THE APPROACH MAKES USE OF THE FACT THAT IN ANIMATION, ANY IMAGE IN THE SEQUENCE IS USUALLY ALMOST IDENTICAL TO ITS PREDECESSOR. HENCE, MOST INFORMATION REQUIRED FOR VISIBLE STATUS DETERMINATION NEEDS NOT BE RECOMPUTED IF FRAME-TO-FRAME COHERENCE PROPERTY IS INCORPORATED INTO THE IMAGE GENERATION PROCESS.
