切片厚度加权的二次误差测度网格简化算法
Mesh Simplification with Slice Thickness-Weighted Quadric Error Metric
摘要
Abstract
Aiming at the low efficiency of triangular mesh simplification and the loss of subtle features on the model surface,the classical quadratic error metric algorithm was improved based on the model slice processing algorithm.The algorithm used the half-edge structure to store the model data,and used the least-cost edge collapse quadric error metric algorithm to analyze the distance from the point to the adja-cent plane,and the slice thickness weight was used to reduce the step surface,thus ensuring the subtle features of the simplified model surface.The experimental results show that the proposed algorithm is 9.2％ higher than the classical quadratic error metric algorithm for the number of more than 60000 origi-nal triangular faces,and the proposed algorithm is 7.1％ higher than the classical quadratic error metric algorithm for the less than 10000 original triangular faces,and the fine features of the model are well preserved after large scale simplification.关键词
