Abstract: In recent years, computer crowd animation has been widely used in various applications such as virtual reality, computer game, education, amusement, and simulation training. The critical two areas of crowd simulations include: the first one is focusing on the simulation model of large crowd motion that is how to simulate realism behavior in crowd animation; the second one is high-quality visualization that is how to regularly use virtual scene in large crowd motion by 3D model. Some wonderful results have been achieved in the two areas. The authors presented the definition of crowd animation and structure of crowd animation, gave a survey on realism behavior in crowd animation from crowd simulation timeline, crowd modeling and crowd simulation algorithms. At last, the authors also presented the conclusions and discussed the prospect.

Key words: crowd animation, realism behavioral, cognize modeling, behavioral modeling
