摘要

本文提出了一个弹性变形角色骨骼驱动动画的框架。字符嵌入在粗体积控制格中,该控制格提供了应用有限元法所需的结构。为了结合骨架控制,我们沿着简单骨架的骨架引入线约束。骨骼被制作成与控制晶格的边缘重合,这使我们能够使用代数方法有效地应用约束。为了加速计算,我们将体积网格的区域与特定的骨骼相关联,并执行局部线性化的模拟,这些模拟在每个时间步混合。我们在控制格上定义了一个层次基础,因此对于详细的交互,仿真可以适应细节级别。我们展示了动画复杂模型的能力,使用简单的骨架和粗体积网格,以一种以交互速率模拟二次运动的方式。

Interactive skeleton-driven dynamic deformations
This paper presents a framework for the skeleton-driven animation of elastically deformable characters. A character is embedded in a coarse volumetric control lattice, which provides the structure needed to apply the finite element method. To incorporate skeletal controls, we introduce line constraints along the bones of simple skeletons. The bones are made to coincide with edges of the control lattice, which enables us to apply the constraints efficiently using algebraic methods. To accelerate computation, we associate regions of the volumetric mesh with particular bones and perform locally linearized simulations, which are blended at each time step. We define a hierarchical basis on the control lattice, so for detailed interactions the simulation can adapt the level of detail. We demonstrate the ability to animate complex models using simple skeletons and coarse volumetric meshes in a manner that simulates secondary motions at interactive rates.
