我们提出了一种基于单纯形网格表示和变形的复杂模型动画制作方法。单纯形网格的特征在于三个顶点之间的连通性，并且可以通过对偶从三角剖分获得。除了他们的一般性的表示，单纯形网格有一个紧凑和明确的形状描述，有关的概念，平均curvity.We设计了一个基于物理的变形算法，依赖于这些网格的内在形状表示。该算法处理不同拓扑或边界条件的对象之间的变换。从深度图像或三角剖分数据中提取各种形状的单纯形网格，然后应用广义网格变换进行变形。
We propose a methodology for animating complex models based on simplex mesh representation and deformation. A simplex mesh is characterized by a connectivity between vertices of three and can be obtained by duality from a triangulation. In addition to their generality of representation, simplex meshes have a compact and unambiguous shape description, related to the notion of mean curvature.We devised a physically-based metamorphism algorithm that rests on the intrinsic shape representation of these meshes. This algorithm handles transformations between objects of different topology or boundary conditions. Various simplex mesh shapes were extracted from range images or some triangulated data and then metamorphosed by applying generalized mesh transformations.
