实现复杂填充图案定制的多边形拟合模型

Polygon fitted model for complex filled patterns customization

提出了实现复杂填充图案定制的多边形拟合模型 ,即将圆看作多边形 (至少 12边形 ) ,依所处相位及拓扑关系对诸边连接 ,即可构成圆形填充图案 ,再以此填充图案为基础 ,去掉某些边则为弧段 ,半径的不同则可产生曲率不同的弧 ;将不同的弧段相连可构成任意的曲线 ;最后 ,不同曲率半径的圆、弧和CAD软件系统提供的点、线元素一起作为基本填充元 。

Most of CAD softwares offer the simple filled patterns only. This paper introduces the idea of polygon fitted model for complex filled patterns customization. That is, the circle is regarded as a polygon(at least dodecagon). And connect the polygon edges in different ways to make up the desired complex filled patterns. Two customization samples for filled patterns and their text description files are given.
