以复形为基础的非流形造型与基于物理的造型相结合的物体表示

提出一个新的表示物体的框架。通过非流形造型与基于物理的造型相结合，从拓扑结构和几何信息两个方面扩大了模型的表示范围。以代数拓扑中的复形为基础的非流形造型的作用是生成物体的拓扑框架，既可以表示ＣＡＤ的物体，更适合表示具有复杂拓扑结构的自然物体。基于物理的造型的作用是在拓扑框架上生成最终的几何信息。二者的结合提供了一种新的几何造型手段。

Representing Objects by Combining Complex based Non manifold Modeling and Physically based Modeling

This paper presents a new framework for representing objects. Representing objects by combining non manifold modeling and physically based modeling enlarges the representing domain for both topology and geometry. Complex based non manifold modeling generates topology framework of an object. It is suitable for representing both objects in CAD and especially natural objects with arbitrary topology, which usually contain multiple holes and branches. Physically based modeling generates geometric information on the basis of the topology framework. Combining non manifold modeling and physically based modeling presents a new method for geometric modeling.
