Crowd Behavior Animation in Three-Dimensional Space

Abstract

This paper proposes an animation method for crowd behavior in three-dimensional space. In this method, each movement model in the computer generated virtual reality space has a movement vector and personal space to avoid collisions with other movement models. When a movement model enters the personal space of an another movement model, the movement model avoids a collision with the incoming models by a calculation of the movement vector. The uniqueness of the proposed method is that real time behavior animation in crowds can be realized by a simple geometric calculation, and the general idea of personal space can be applied to fast moving objects. Our experimental results demonstrate that this method is effective in real time animation.
