摘要
给出了一种使三次均匀有理Ｂ样条曲线光顺的权因子优化算法，通过优化计算，得到了光顺曲线的权因子。本文采用了非线性优化技术计算光顺曲线的权因子。
This paper introduces a weights optimization method which makes uniform rational B spline curves fairness. The trapezoid integration is used to approximatly calculate the second derivative norm and the third derivative norm and the weights of fairing curves are obtained through calculation of optimization. Nonlinear optimization techniques are used in this paper.
