> 中文摘要: 提出了一种修改NURBS曲面形状的新方法.利用约束优化方法,得到计算曲面新的控制顶点的显式公式,并给出例子以比较所提出的方法和Piegl方法的效果.
中文关键词: NURBS曲面  形状修改  约束优化
Abstract:A new method for shape modification of NURBS surfaces is proposed in this paper. Explicit formulae for computing new control points are derived by using constrained opimization method. Examples are also given to compare the results of Piegl's method with those of the new method.
