Physically Based Character Animation, Editing, Control, Deformation, and Contact

这项研究调查了基于物理的角色动画中的挑战。数据驱动技术可以实现高质量的动画，但当环境或角色发生变化时，为虚拟人生成自然可信的运动变得困难。我遵循的方法是使用基于物理的模拟，在创建新的角色编辑工具时使用，并在开发控制器时允许虚拟角色交互地产生物理正确的响应。该方案涉及手部在操作过程中的灵巧运动以及全身运动，其方法既包括物理方法，也包括涉及捕捉运动和力的数据驱动方法，提出了一系列新的编辑和控制器设计策略。这项研究还致力于开发新的近似和模型来模拟变形和接触，因为快速和准确地模拟复杂的被动现象将有许多好处，包括更快地学习离散事件驱动的角色控制器。这项工作在游戏、培训、人体工程学、康复和机器人方面都有应用，并将有益于计算机动画产业，加拿大在该产业一直是先驱，并继续拥有强大的产业存在。

This research investigates challenges in physics based character animation. Data driven techniques allow for high quality animations, but producing a natural plausible motion for a virtual human becomes difficult when changes to the environment or character are introduced. The approach I follow is to use physics based simulation, in the creation of new tools for character editing, and in the development of controllers that allow a virtual character to interactively produce a physically correct response. This proposal involves dexterous motions of hands during manipulation as well as full body motion, with the approach that both physics, and a data driven methods involving capture motion and forces presents a collection of new editing and controller design strategies. The research also addresses the development of new approximations and models for the simulation of deformation and contact because fast and accurate simulations of complex passive phenomena will have many benefits, including faster learning of discrete event driven character controllers. This work has applications in games, training, ergonomics, rehabilitation, and robotics, and will be of benefit to within the computer animation industry, in which Canada has been a pioneer and continues to have a strong industrial presence.
