Motion Skills for Simulated Humans

描绘人体运动是计算机图形学和动画的一个重要方面，其应用包括训练模拟、计算机游戏和电影视觉效果。与计算机图形学中的其他现象一样，如皮肤的逼真渲染或流体或头发的逼真动画，根据基本原理和对给定现象的深入理解开发的模型为实现高质量和可推广的结果提供了最好的前景。基于物理的原则性模型的发展从根本上改变了用于计算机图形渲染和被动现象动画的工具集。然而，在基于物理学的人体运动模型上取得类似的进展仍然具有巨大的挑战性。它需要解决许多相同的控制问题，而这些问题似乎是人体在日常运动中毫不费力地解决的。我们的研究目标是，目前的技术水平与人类相当高的运动技能之间仍然存在着相当大的差距，目前的技术水平主要基于运动剪辑和布娃娃模拟。我们的重点是运动，如行走、攀登、室内和室外环境中与运动相关的任务，以及对象抓取和操纵。

Depicting human movement is an essential aspect of computer graphics and animation, with applications that include training simulations, computer games, and visual effects for film. As has been the case for other phenomena in computer graphics, such as the realistic rendering of skin or the realistic animation of fluids or hair, models that are developed from first principles and from a deep understanding of a given phenomenon offer the best prospects for achieving high-quality and generalizable results. The development of principled physics-based models has radically transformed the tool-sets used in computer graphics rendering and for the animation of passive phenomena. However, achieving similar progress for physics-based models of human motion remains hugely challenging. It requires solving many of the same control problems that are seemingly solved so effortlessly by the human body during our daily movements. Our research targets the considerable gap that remains between the current state of the art, which is largely based on motion clips and "rag doll" simulations, and the considerable motor skills of humans. Our focus is on motions such as walking, climbing, movement-related tasks in indoor and outdoor environments, and object grasping and manipulation.
