使用动作捕捉数据生成的角色动画具有许多在人体运动中看到的风格细节，而通过模拟生成的动画对于角色的动态参数来说在物理上是真实的。我们通过使用动态模拟和约束跟踪和修改人体运动捕捉数据来结合这两种方法。跟踪系统生成适合图形字符的运动，同时保持原始人体运动的特征。该系统施加接触和任务约束，以增加与环境交互的动态影响并修改行为级别的运动。该系统能够编辑动作数据以适应角色和环境的变化，并在动作捕捉序列之间创建平滑的过渡。我们通过跟踪各种上半身运动的数据以及使用不同的运动学和动态参数对模型进行动画处理来展示结合这两种方法的力量。
Character animations produced with motion capture data have many of the stylistic details seen in human motion while those generated with simulation are physically realistic for the dynamic parameters of the character. We combine these two approaches by tracking and modifying human motion capture data using dynamic simulation and constraints. The tracking system generates motion that is appropriate for the graphical character while maintaining characteristics of the original human motion. The system imposes contact and task constraints to add dynamic impacts for interactions with the environment and to modify motions at the behavior level. The system is able to edit motion data to account for changes in the character and the environment as well as create smooth transitions between motion capture sequences. We demonstrate the power of combining these two approaches by tracking data for a variety of upper-body motions and by animating models with differing kinematic and dynamic parameters.
