| 摘 要： | 在计算机辅助几何设计中，曲线，曲面拟合多彩多项式作为基函数，本文通过几种曲线，曲面生成算法分析，提出了一种Ｂ３样条的拟合方法。它具有Ｂ样条的主要优点，且通过所有型值点，这一方法适用于自由曲线，曲面的设计。本文还结合拱坝体形设计实例说明了用此方法进行造型设计的方法。

| Abstract: | Polynomial is often used to approah curve surface as a kernel funcition on the comuter aided geomtric design. B3-Spline methed Of approaching curve surface is proposed based on the analysis of me curves to be formed. The method is as goos as B-Spline and all controlling points are passed. In addition, Some examples of the arch-dam moulding are gived in this paper. |
