在三角网格的生成过程中,不可避免地会出现噪声,如何有效地消除这些噪声已经成为计算机辅助设计以及计算机图形学领域的一个重要课题.该文给出了基于主方向的平滑算法,并结合平均曲率流算法和法向滤波算法进行了改进.此平滑算法能够较好的保持曲面的几何特征,防止曲面特征磨光的情况,并能使得曲面原有的特征曲线得以保持.此算法仍是一个线性算法,实验结果说明了实验的有效性.
Abstract：The undesirable noise will inevitably occur in the generation of the triangular mesh.Therefore,how to effectively remove the noise has become an important project in computer-aided design and computer graphics.The paper presents a smoothing algorithm based on the main direction combined with the mean curvature flow and the normal filter method.This smoothing algorithm preserves desirable geometric features,avoids over-smoothing and keeps the original characteristic curve.It's linear and the result of the experiment proves the validity of this algorithm.
