| 摘 要： | 本文从具有Ｂｅｚｉｅｒ性质的一般性参数曲线着手，推导出导关系数为４的另一种变形Ｂｅｚｉｅｒ曲线，由它生成的双三次Ｂｅｚｉｅｒ曲面具有拟合速度快、精度高的特点，同时还可用于对控制点的拟合。为减少拟合时间、较快地生成自由曲面提出了一种策略。

| Abstract: | Starting with general Bezier curve, author Bezier(F-Bezier) curve in which thecoefficient of der ivatives vector is 4 is presented in this paper. The two cubic F-Bener surface forming from this curve has high speed fitting and high accuracy, and fit to controlpoint. This paper gives the method of decreasing the fitting time and rapider forming the parametric surface. |
