| 摘 要： | 1.引言 任意拓扑的三角形网格的曲面插值和逼近又称曲面重构,特别是样条曲面插值和逼近,是反向工程中非常重要的一部分,在CAD/CAM/CAGD以及计算机图形图像中有非常广泛的应用,是近年来讨论比较多的问题之一,其中一般包括多元样条逼近方法,Bezier样条逼近方法和NURBS逼近方法.复杂曲面的逼近可分为分片逼近和整体逼近,通常的做法

| Abstract: | The purpose of this paper is to present a method for choosing interpolation nodes of spline approximation of complicated surfaces. The method can be used to a variety of surfaces which are equivalent to disks topologically. Moreover the method shown in this paper is better than other ordinary optimization methods. |
