A CURVILINEAR COLLISION DETECTION SCHEME FOR AVATARS IN MOTION IN A COLLABORATIVE VIRTUAL ENVIRONMENT

摘要

To assure collision-free movement of an avatar in a Collaborative Virtual Environment (CVE), a collision management scheme must be present to prevent avatars from trespassing on the LocalSpace of obstacles and other avatars. Furthermore, this scheme must provide tools for collision-free linear, as well as, curvilinear motion. This paper seeks to extend the linear concept of horizontal collision detection for Avatar with Avatar to include curvilinear motion.
