摘要
本文给出了带有给定切线多边形的保形有理三次Ｂ样条曲线，其部分权因子可通过选取切点的位置来确定。由此方法还导出了保形有理三次Ｂ样条插值曲线。最后，给出了两个例子。
A closed shape preserving rational cubic B-spline curve with given tangent polygon is presented and part of its weight factors can be given by choosing the positions of the contact points. A shape preserving rational cubic B-spline interpolation curve is derived. Two examples are given.
