Representing objects by combining non manifold modeling and physically based modeling enlarges the representing domain for both topology and geometry.

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。

In the progress of modeling, We often meet Non-Manifold polygonal surfaces, but a lot of graphical algorithms that operate exclusively on a Manifold polygonal surfaces.

实际建模过程中，经常会遇到非流形的多边形表面，但很多现有的图形学算法都是基于流形结构的。

An identification edge structure is put forward to represent non manifold modeling, which is built on the concepts and methods of the complex and CW complex in algebraic topology.

提出了一个非流形结构的表示方法——粘合边结构，其数学基础是代数拓扑中的复形理论。
