摘要
B样条曲线的升阶是CAGD中的一个重要课题 .本文根据传统的样条函数理论 ,提出了一个用高次B样条函数表示低次B样条函数的方法 .该方法用于B样条曲线的升阶是快捷、有效的 .
Degree elevation of B-spline cruves is an important issue in CAGD.In this paper,a method for representing B-spline basis functions of degree p by those of degree p+1 is provided.This method is simple and effective when being used to raise the degree of B-spline curves.
