Mesh simplification algorithm based on control point error control
基于控制点误差控制的网格简化算法

In this paper, a mesh simplification algorithm based on control point error control was introduced. The first control points are the center points of the initial mesh triangles. The second control points are the vertexes of the characteristic lines. The distance between the control point to the under control triangle is the error between the initial mesh and the simplified mesh, The triangles are eollapsed in order according to the weights of the triangles, The triangle collapse operation should meet the requirement that the distances between the control points and the under control triangles are less than the threshold value. Finally the validity of this algorithm is verified by the experiment.
