A Study on Improving the Accuracy of Continuous Collision Detection of Rotating Rigid Bodies in Real-Time Graphics

Abstract

Few of the CCD (Continuous Collision Detection) methods in today’s computer games deal with rotational motion. In addition, the Speculative CCD method of Unity, which is an example of a method that addresses rotational motion, has the problem of low accuracy in collision determination. To solve this problem, this study aimed to improve the accuracy of continuous collision determination for rotating rigid bodies by interpolating the rotational motion trajectory by a fan shape, which is an approximate shape of the rotational motion trajectory. In this paper, we define and propose an interference determination between a fan shape and several primitive shapes.
