摘要
使用重心坐标,以B-网为工具研究了一元顶样条的结构,给出了一元顶样条存在的充要条件;获得了基本顶样条的显式表示;得到了适合于Hermite插值的顶样条;讨论了顶样条与多结点B样条的关系。
We studied the necessary and sufficient condition of theunivariate vertex spline existence, and constructed fundamental vertexspline and Hermite interpolation vertex spline. In the last section,We dis-cussed the relation between vertex spline and multiple konte B-spline.
