One Effective Method of Identifying Feature Edges of Triangular Meshes

Zhang Wei;Jin Tao;Department of Mechanical Engineering, Zhejiang Institute of Mechanical & Electrical Engineering;Institute of Chemical Machinery, Zhejiang University;  
Feature edges identification for triangular meshes is widely used in digital geometry processing and computer aided manufacturing(CAM) of dies. The shortcomings and corresponding origin of the existing algorithms about feature edges detection are pointed out in the paper. Furthermore, a new robust algorithm that identifies feature edges of triangular meshes is presented. The proposed algorithm is based on the identification of feature vertices of the mesh, and it can identify the edges with small dihedral angles which are often ignored by the existing algorithms. The proposed algorithm can improve the accuracy of identifying mesh edges with C1 discontinuities. This conclusion is supported by lots of examples in the paper.
