摘要
通过对三次均匀有理B样条曲线权因子几何意义的分析 ,从而研究了三次有理B样条曲线的几何特性。在此基础上深入探讨了权因子对于B样条曲线形状的影响 。
By analysing geometrical meanings of the cubic rational B spline weight factor, the paper presents a study of the geometrical characteristics of cubic rational B spline curves. It also discusses the effect of the weight factor on the shape of B spline curves, providing a way for constructing B spline curves for special requirements.
