| 摘 要： | 将选点修改法和能量法相结合，提出了一种新的曲线光顺方法。和传统的选点修改法以及能量法的区别是：选点修改法每次只修改一个坏点，能量法一次性地修改所有控制顶点，而本文的方法则是用能量法一次性地修改所有对坏点有影响的控制顶点。数值实例表明，这是一种有效的曲线光顺方法。

| Abstract: | A new fairing method for B-spline curves is presented. Our new approach differs trom me traditional way of selecting and modifying bad points in that we modify all the control vertices of a B-spline curve which have influence to the bad points through energy minimization. There is a difference between our approach and the traditional energy method that we only modified those vertices which affect the bad points rather than all control vertices. Numerical experiments show that this is a very practical fairing approach for curves. |
