正多边形螺旋线的画法

Method for Normal Polygon

在计算机图形、图象处理技术中，算法占有极其重要的地位。正多边形围绕其中心旋转且放大，得到一组正多边形，若放大后的正多边形恰好包含它的前一个正多边形，由这样一组正多边形便形成了螺旋线。对于正多边形如何生成螺旋线，提出了一个通用的算法，讨论了其中容易出现的问题，给出了实例。

Algoriths play an important part in computer graphics and image processing.A series of Normal polygon can be got through continuously rotating and amplifying a normal polygon on its center.Normal polygon helix will be got if the next Normal polygon just include the previous one.One General Algorithm for helix of Normal polygon is given.One problem that ofen occured is also discussed.Some helixes of Normal polygon are presented.
