计算机群体动画中的真实感行为综述

Survey on realistic behavior in crowd animation

近年来,计算机群体动画在虚拟现实、计算机游戏、在线教育、娱乐和模拟训练等多个领域得到广泛深入的应用。目前群体动画技术中两个关键的研究领域是:1)研究并建立大规模群体运动的仿真模型,即如何实现对群体运动的真实感行为模拟;2)研究群体动画中高质量的可视化效果,即如何将大规模群体运动以三维的方式逼真地展现到虚拟场景中。现在这两个领域的技术研究也得到了一些很好的研究成果。定义了群体运动的概念,并给出了群体动画的引擎框架;对群体运动的真实感行为从其发展历程、模型和关键算法等方面进行了归纳与分析;最后讨论了群体动画真实感行为的发展趋势。

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.
