一种保持特征的三角网格光顺方法

Triangle Mesh Smoothing Method with Feature Preservation

网格光顺是逆向工程中一种常用的数据处理手段,其主要目的是为了减少网格模型中的噪声,提高网格模型的质量。但网格上的一些特征常常会在光顺时丢失。如何在光顺时保持网格模型的特征成为提高光顺质量的一个关键问题。在实现常用光顺方法的基础上,该文提出了一种能较好保持网格特征的自适应光顺方法,通过对特征进行判断,根据网格顶点的不同性质对其采用不同的操作方法以达到光顺和保持特征的目的。

Mesh Smoothing is a common used method of processing triangle mesh in reverse engineering.The main effect of this method is to reduce the noise of triangle meshes and to improve the quality of the mesh.Some features or shapes of triangle meshes often lost during smoothing.So smoothing with Feature Preservation is a key problem of improving the quality of smoothing.This paper proposes a new triangle mesh smoothing method which keeps the shape or feature of meshes.It adopts a way to recognize the shape or feature of meshes and uses different ways to update different vertexes of the mesh.
