摘要
利用四次的Bézier曲线段构造了GC2连续的参数四次插值样条曲线,该样条曲线是保形的和局部的,且计算十分简单,所有的Bézier点由型值点和曲率直接计算产生,避免了求解矢量方程。最后,给出了一个数值实例。
An algorithm for constructing GC2 continuous parametric curve by a sequence of quartic Bezier segments is presented. The curve is shap preserving to data points, and the local shape modification is possible. Finally, a numerical example illustrates that the algorithm is effective for computing aided geometric design and computer graphics.
