Motion Skills for Simulated Humans

描绘人体运动是计算机图形和动画的一个重要方面，其应用包括训练模拟、电脑游戏和电影视觉效果。与计算机图形学中的其他现象（如皮肤的逼真渲染或流体或头发的逼真动画）一样，从基本原理和对给定现象的深刻理解中开发的模型为获得高质量和可推广的结果提供了最好的前景。基于原则的物理模型的发展从根本上改变了计算机图形渲染和被动现象动画中使用的工具集。然而，在基于物理的人体运动模型上取得类似的进展仍然是一个巨大的挑战。它需要解决许多与人体在日常运动中似乎毫不费力就能解决的控制问题。我们的研究目标是解决当前技术水平（主要基于运动剪辑和“布娃娃”模拟）与人类相当大的运动技能之间的巨大差距。我们的重点是运动，如步行，攀爬，室内和室外环境中的运动相关任务，以及物体抓取和操作。

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.
