Aiming at the problem that existing virtual group animation tcchniques is difficult to ensure real-time animation and authenticity, a new method is proposed which combines the motion capture data and particle swarm system to achieve the movement of the group in this paper. In this way, firstly, the motion capture data is analyzed and studied, and then Maya embedded scripting Language(MEL) is used to create and drive the three-dimentional skeleton model. These two steps can generate the skeleton movement and animation. Finally, the movement of the group is realized by using particle swarm system. The experiment results show that this method can successfully achieve the motion simulation of the ancient group of soldiers marching in 3D scene, and also can improve the efficiency and fidelity of the production of group animation.%针对现有的虚拟群体动画技术难以同时保证动画的实时性和真实性等问题,提出了一种采用运动捕获数据和粒子群系统相结合的方法来实现群体的运动.对运动捕获数据进行分析与研究,采用Maya嵌入式脚本语言(MEL)建立并驱动三维骨架模型,从而产生骨架的运动,形成动画,最后采用粒子群系统实现群体的运动.经实验证明,此方法在三维场景中成功实现了古代士兵群体的行军运动仿真,且提高了制作群体动画的效率和逼真度.
