| 摘 要： | 针对不均匀截面线族曲面生成问题，本文提出了一种基于最小二乘法的曲面生成算法。这种算法在插值的思想上融合了逼近的思想，因此解决了困截面线旅不均匀而使曲面参数线族不合理并导致曲面光顺性不好的问题。该算法已在自行设计的面向数控的曲面造型系统中实现．

| Abstract: | An algorithm for free form surfaces design, which is based on least sqares and fit for uneven cross-sectional curves, is presented in this papeL The approwiate idea is combined with the interpolate idae in this algorithm, so the problem which the parameter curves is unreasonable and the smoothness is dissatisfied can be solved. This algorithm has been successfully used in a NCoriented free surface design system. |
