摘要
本文提出了空间三角形网格的优化算法,给定一组三维散乱点集和一个初始三角形网格,对三角形网格顶点位置优化和应用三角片局部细分方法,使该网格能更好的逼近三维散乱点,提高了网格对散乱点的逼近精度。
A mesh optimization algorithm is presented. Given a set of 3D scattered data point and aninitial triangular mesh,the mesh can be optimized and approximate the data points more accurately by the optimization of venices positions and lOcal tesselation.
