| 摘 要： | 介绍了双三次B样条曲面的变形基础和曲面拼接的表达式，提出了一种双三次B样条曲面生成的改进算法，采用点约束、目标曲线约束两种几何约束驱动双三次B样条曲面变形，在点约束求解中以控制节点位移最小为目标函数，使用LINGO软件计算得到该目标下的最优解，利用MATLAB辅助计算得到变形结果，最后给出了计算实例验证了该方法的可行性。

| Abstract: | In this paper, the basis for deformation of bi-cubic B-spline surface and the expression of curved surface splicing are presented. A improved generating algorithm of bi-cubic B-spline curve is discussed. Geometrical constraints including point constraint, and target curve constraint are adopted to During the point constraint solving, with the control minimum node software was used to obtain the optimal solution under the target. In drive bi-cubic B-spline surface deformations. displacement as objective function, the LINGO the target curve constraint, the results of deformation are auxiliarily calculated by MATLAB. The calculation examples were finally given, and the results indicate that the method is feasible. |
