自主性与可控性相结合的群体动画运动控制

The Motion Control with Combination of the Controllability and Autonomy for the Crowd Animation

提出一种自主性与可控性相结合的群体动画运动控制方法.该方法利用全局路径规划方法寻找群体自主运动的最短路径,群体在以该路径自主运动时,可以通过改变路径曲线的控制顶点实现对群体运动的控制;利用引导分量和范围保持分量的矢量场以及个体的引力或斥力分量叠加的方法实现个体的运动控制,通过动态地改变引导分量实现个体运动过程的实时交互控制.实验结果表明:该方法较好地模拟了群体动画自主性运动,同时满足实时交互控制的要求,具有较好的可控性.

This paper proposes a method which combines the controllability and autonomy of the motion control for the crowd animation.This method uses the global path planning to find a best path for the autonomous motion of the group,and complete the controllability by changing the motion curve which the group move on,and it uses the vector field of the guide sub-vector and the range keeping sub-vector,and their superposition with the attraction/repulsion sub-vector of the individuals to complete the individuals motion,achieves the real-time interaction by changing the consistency sub-vector.The experiment result shows that this method simulates the autonomous motion really,and fulfills the requirement of the real-time interaction control,has a good controllability.
