Title: Generating Algorithm of Progressive Mesh Model Based on Edge Collapse
Abstract: In order to implement progressive mesh representation of 3D model,the calculation method of collapse cost of model simplification based on edge collapse mode is improved.Firstly,model data from SMF data file is obtained,and the 3D model in the memory is established rapidly,and the weight calculation method of Garland's EM algorithm is redesigned.The square of the largest deviation of triangular plane normal adjacent to the vertex is used as the importance degree of vertex,and bring it into error metric formula,by simplifying progressive mesh is generated.The following experiment shows that the algorithm is succinct,and the generating speed of mesh and the contour information of model are completely preserved.
