This paper uses the idea of matrix circles model which regards the circle as a polygon (at least dodecagon), and connect the polygon edges in different ways to make up the desired filled pattern.
文中用阵列相圆模型的设计思想 ,将圆看作多边形 (至少 12边形 ) ,对每个边进行拓扑连接 ,即可构成圆圈符号填充模式 ;再以此填充模式为基础 ,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、曲线和原有的点、线一起作为基本图元 ,便可组合成任意复杂的图案填充模式 。
