摘要: 各类网格分割法将曲面网格进行分割后,各子网格区域之间的交界线便可以作为曲面网格的封闭特征线。相反,如果根据网格模型的几何、拓扑特征,确定了网格模型的封闭特征线后,网格曲面便被这些特征线分割开来。为此,从曲面网格封闭特征线的角度出发,提出一种基于特征线的曲面网格分割方法。实验验证了该方法的可行性和有效性。

Abstract: After being segmented by the methods of mesh segmentation for the surface mesh,the common boundaries of each sub-mesh which are the surface mesh’s closing feature lines.On the contrary,according to the geometry and topology characteristic of the mesh model,after extracting the closing feature lines of the mesh model that the surface meshes will be partition.Therefore,according to the surface mesh’s closing feature lines,a method of mesh segmentation is put forward in this paper.The experiments demonstrate the feasibility and validity of the method of segmentation proposed in this paper.
