Voronoi图，又叫泰森多边形或Dirichlet图，它是由一组由连接两邻点直线的垂直平分线组成的连续多边形组成。-Here to the input voronoi, tyson polygons or dirichlet, it is connected by a group of the two neighboring points straight vertical bisectors of polygon. a series of

Voronoi算法，画出网络三角形，然后做多边形连线，泰森多边形算法

ABAQUS中用来绘制二维泰森多边形的插件，可以方便快捷的绘制出晶粒(ABAQUS used to draw two-dimensional voronoi plug-in, can be convenient and fast draw the grain)
