摘要
用Ｂ样条函数对复杂曲面进行数据拟合。利用Ｂ样条曲线、曲面的重顶点技术，对具有折痕、或坑洼的特殊情况进行了强约束条件的曲面逼近。
This paper presents an important method for the curves and surface with imposed condition approximation.The paper mainly concerns with the multiple vertices method to approximate some imposed conditions on curves and surface.It is found that faults and creases of surface are approximated by B spline.The complex surface with imposed conditions can be modeled by computer.
