圆上的点

CirclePoints 函数返回等间距分布在圆上的点的坐标. 以下为通过将其与图形基元结合后可完成的一些范例.

画出指向圆上七个等间距点的箭头.

In[1]:=

Graphics[Arrow[{{0, 0}, #}] & /@ CirclePoints[7]]

Out[1]=

将前八个标准多边形放在八边形的顶点上.

In[2]:=

Graphics[MapIndexed[RegularPolygon[#1, 0.25, First@#2 + 2] &, CirclePoints[8]]]

Out[2]=

将 CirclePoints 和 BezierCurve 组合使用.

In[3]:=

Graphics[{ BezierCurve[{{0, 0}, ##, {2, 0}}], BezierCurve[{{0, 0}, ##, {0, 2}}], BezierCurve[{{0, 0}, ##, {-2, 0}}], BezierCurve[{{0, 0}, ##, {0, -2}}] } & /@ CirclePoints[32] ]

Out[3]=

In[4]:=

Graphics[Table[ Rotate[BezierCurve[{{0, 0}, #, {1, 0}}] & /@ CirclePoints[8], i], {i, 0, 2 Pi, Pi/16}]]

Out[4]=
