摘　　要：人类的动作捕捉嵌入丰富的细节,很难使用竞技动画合成技术来实现,当出现非预期的情况时,需要及时创建捕捉动作的记录数据进行响应。本文介绍了一种新技术,通过组合对接触力的物理模拟和一个专门的决策,重入动作库中的影响搜索程序,将一个非预期的影响整合到动作捕捉动画系统驱动中。使用一个驱动的动态模型,系统生成一个基于物理响应而连接的动作捕捉片段。该方法允许角色基于特定的动态效应来应对意想不到的环境的变化。结论显示了在武术动作捕捉中,系统在各种条件下的不同响应效果较好。Human motion capture embeds rich detail. The style is difficult to generate with competing animation synthesis technologies. In unpredicted situations the recorded data requires in-time means for creating responses. This paper intro- duces a novel technique for incorporating unexpected impacts into a motion capture-driven animation system through the combination of a physical simulation which responds to contact forces and a specialized search routine which determines the best plausible re-entry into motion library playback following the impact. The method allows characters to respond to unexpected changes in the environment based on the specific dynamic effects. Conclusion shows that？？response effect of the system in martial arts motion capture in various conditions is good.
