摘要
n次B(?)zier曲线有一个求导公式为: P'(t)=n(P-1,^(n-1)(t)-P_0,^(n-1)(t))使用的是控制网格段(P_(i+1)-P_i)。在本文中我们对有理B(?)zier曲线也建立这种形式的导数。
One equation is presented which express the derivative of a rational Bezier curve in terms of its control points and weights. This equations is natural generalisations of the non-rational case and various properties are found from them.
