摘要
描述了一种与给定多边形相切的有理样条曲线的算法。在算法中,所有的有理样条曲线的控制点可以通过对多边形的顶点简单计算产生。所构造的曲线对多边形具有保形性。曲线可以局部修改。最后给出了两个算例。
In this paper, an algorithm for constructing rational spline curve which is tangent to the given polygon is described. The control points of the rational spline to be constructed are computed simply by the vertices of the given polygon. The constructed curve is shape-preserving to the polygon. The local modification to the rational spline curve can be completed by simply adjusting the corresponding control parameters. Two examples are given.
