摘要
针对由四点拟合成一条三次B样条曲线过程中计算量大的缺点,提出了一种简单的二次B样条曲线拟合算法。即用两条二次B样条曲线近似一条三次B样条曲线,以期达到计算量小,光滑度也达到要求,提高B样条曲线的绘制速度。
Because of fussy calculate in the course of fitting a thrice B-spline curve by four points, we put forward a simple arithmetic of secondary B-spline curve fitting. That is to say, A thrice B-spline curve is replaced with two secondary B-spline curves that can produce simple compute, satisfactory slick degree and quick speed.
