On McAllister s View of Scientific Revolution;
浅析麦卡里斯特的科学革命观
In this paper, we obtain the tanget vector at each point of the regular rational Be ziter curve of degree n by using the improved rational de Casteljau algorithm.
通过利用改进的有理德卡斯特里奥算法求得正则有理n次Bezier曲线各点处的切矢,由此得到各点的单位法矢量,应用于求原始曲线的等距曲线,从而巧妙地解决了原始正则有理n次Bezier曲线上各点的单位法矢量难求的困难。
