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

本研究探讨了基于物理的角色动画的挑战。数据驱动技术允许高质量的动画，但是当环境或角色发生变化时，为虚拟人产生自然可信的运动变得困难。我所遵循的方法是使用基于物理的模拟，创造用于角色编辑的新工具，以及开发允许虚拟角色以交互方式产生物理正确反应的控制器。这一建议涉及灵巧的手在操作过程中的运动以及全身运动，与物理的方法，以及数据驱动的方法，包括捕捉运动和力量提出了一系列新的编辑和控制器设计策略。该研究还解决了变形和接触模拟的新近似和模型的发展，因为快速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字符控制器。这项工作适用于游戏、训练、人体工程学、康复和机器人技术，并将有利于计算机动画行业，加拿大一直是该行业的先驱，并将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.
