摘要
针对双圆弧拟合算法绘制一条B样条曲线,需要反复多次计算各坐标分量的3次多项式,计算量大,绘制拟合速度极慢,难以满足实际需要等情况,该算法提出了一种简单的二次B样条曲线拟合算法,该算法提高了B样条曲线的绘制速度,有效地解决了4个点以上控制点的拟合问题。
Because of fussy calculate in the course of fitting a thrice B-spline curve by four points. This paper put forward a simple arithmetic of secondary B-spline curve fitting. That is to say thrice B-spline curve is replaced with two secondary B-spline curves that can produce simple compute, satisfactory slick degree and quick speed.
