Edge Collapse Considering Triangular Mesh for Model Simplification

摘要

Because of re-triangularization during the process of traditional edge collapse, this paper introduces a new edge collapsing method improved with the use of triangular mesh. We deal with a series of feature points, and directly establish the triangular mesh which meet the need of simplification, and avoid triangulating secondly. The experiment shows that this method can improve the convergence rate, and simplified effect, under condition of assurance of the triangle mesh approximation precision and the decrease of the amount of the triangular facets.
