摘要
本文取曲线段极值点的参数值和极大值作为控制曲线形状的参数,构造出一类可控制形状的C^2连续插值三次参数样条曲线,同时还给出了使插值曲线保凸或保形的充分条件。
In this paper, a new method of constructing a kind of shapc-controlable C^2-continuous interpolation cubic parametric spline curves is given. Furthermore the conditions under which the interpolation curves are shape preserving or convex preserving are alse given.
