计算机图形学试验 画金刚石 把一个圆周等分成

n份，然后每两点之间连线。当n取奇数时，该图案可一笔连续绘成，即用MoveTo函数确定一个当前点，然后连续用LineTo函数连点成线。

-Computer graphics test painting diamond, such as a circle divided into n parts, and then the connection between every two points. When n is odd, the pattern can be plotted as a sum of continuous MoveTo function to determine a current point, and then continuous LineTo function form of line.
