摘　　要：曲线曲面的光顺处理一直是CAGD中研究的热点问题之一,如何快速、简便、正确地光顺曲线曲面,是光顺处理问题研究的核心。文章针对B-spline曲线提出了一种光顺方法,并描述了其基本原理和光顺准则。实例表明,文章所提出的光顺方法快速、简便,是一种较为实用的光顺方法。同时,该方法也可扩展到对曲面的光顺处理。The process of fairing curves and surfaces is one of important technologies in CAGD.The central problem on fairing surfaces is how to smooth surfaces quickly and simply and rightly.In this paper,a method is put forward for fairing B-spline curves,and the fundamental principle and the fairing criterion are described.Examples experienced show that it is quick and simple,and it is a practicable method for fairing curves.Further more,the method can be extended to smooth bicubic parametric surfaces.
