Optimization of Collision Handling based on Differential Thresholds of Human Perception

Abstract: An efficient collision handling mechanism is essential for most computer animation and to achieve realistic yet efficient animations we need to consider human perception in these animation systems. Current states of art collision handling algorithms do not consider human perception in depth, particularly in differentiating thresholds of various collision parameters. Yet the human perception plays a significant role in the quality of perceived animation when multiple collisions are presented in an animated scene. The responsiveness of the objects at the right time and the right behavior makes the animation system look natural. In this paper we describe an approach, which approximates objects by using an interruptible detection algorithm to proximately test for collisions between different objects. Based on the inputs from the user study made we are able to adjust the various parameters in our collision detection algorithm and were able to get considerable speed up.
