摘要
n次有理Bezier曲线在t点的导矢的第二种表示形式为P'(t)=sum from i=0 to n-1(λ_i(t)(P_(i+1)-P_i)) (山西师大学报97增2已证)本文将给出并证明n次有理Bezier曲线导矢的第三种形式。
The second expresses of the derivative of rational Bezier of degree n P(t) at t isP'(t) =sum from i=0 to n-1λi(t)(Pi+1 - Pi)This paper will proof the third expresses of the derivative rational Bezier curve.
