The whole form of original curve is retained and control points is reduced with discarding detail curve and retaining approximate curve, so the target of fairness is reached.

小波光顺时，通过丢弃细节曲线，保留近似曲线，既保留了原曲线的总体形状，又减少了控制点，最终达到小波光顺的目的。

The algorithm automatically identifies the point at which the NURBS curve has to be faired. Modifying locally the control polygon, the algorithm yields a NURBS curve with improved fairness.

此算法自动找出NURBS曲线需要修改的那一点，局部修改控制多边形，使生成的新曲线更加光顺。
