Abstract

In this paper, we are concerned with modeling and generation of the moving crowd in three dimensional virtual city to increase reality. In the virtual city, the habitants are usually controlled by some strict rules. To actualize more natural atmosphere, many data and rules are needed.

In such case, we can easily control the shape of the crowd by using the characteristics of chaos. Although random numbers are often applied to such purposes, it is difficult to create and control such patterns. We constructed the models of the crowd in the street and the folk dance. The prototype system was developed for evaluation and it was confirmed that users felt easy to generate and control the crowd.
