【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。更多还原

【Abstract】 An algorithm for constructing GC2 continuous parametric curve by a sequence of quartic Bézier 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.更多还原
