人体运动捕捉嵌入了丰富的细节和风格，这是很难产生与竞争的动画合成技术。然而，这种记录的数据需要用于在不可预测的情况下产生响应的原则性手段，例如在撞击后立即产生响应。本文介绍了一种新的技术，将意外的影响到一个运动捕捉驱动的动画系统，通过一个物理模拟，响应接触力和一个专门的搜索例程，确定最好的合理的重新进入运动库播放后的影响相结合。使用驱动的动态模型，我们的系统生成一个基于物理的响应，同时连接运动捕捉段。我们的方法允许角色根据给定接触的特定动态效果对环境中的意外变化做出响应，同时还利用了通过运动捕捉提供的逼真运动。我们展示了我们的系统在各种条件下的结果，并使用武术动作捕捉作为测试平台的不同反应。
Human motion capture embeds rich detail and style which is difficult to generate with competing animation synthesis technologies. However, such recorded data requires principled means for creating responses in unpredicted situations, for example reactions immediately following impact. This paper introduces 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. Using an actuated dynamic model, our system generates a physics-based response while connecting motion capture segments. Our method allows characters to respond to unexpected changes in the environment based on the specific dynamic effects of a given contact while also taking advantage of the realistic movement made available through motion capture. We show the results of our system under various conditions and with varying responses using martial arts motion capture as a testbed.
