Python3使用turtle绘制超立方体图形示例

本文实例讲述了Python3使用turtle绘制超立方体图形。分享给大家供大家参考，具体如下：

利用Python3中turtle的绘制超立方体。

绘图思路：

1）求出边长100的超立方体的点坐标；

以竖直线为依据，将点分为上下两组：

a为上边点列表，b为下边点列表：

a = [[120.71, 50], [50, 120.71], [-50, 120.71], [-120.71, 50], [-50, -20.71], [50, -20.71], [20.71, 50],[-20.71, 50]]
b = [[120.71, -50], [50, 20.71], [-50, 20.71], [-120.71, -50], [-50, -120.71], [50, -120.71], [20.71, -50],[-20.71, -50]]

2）编写绘制直线函数；

3）编写主程序：绘制点，绘制六角形直线，绘制竖直直线，绘制斜线

代码片段如下，可能不是最简洁的，如有好的建议，请不吝指正。

import turtle
# 创建绘制直线函数
def drawLine(p1, p2, size=3, color="black"):
 turtle.penup()
 turtle.goto(p1)
 turtle.pensize(size)
 turtle.pencolor(color)
 turtle.pendown()
 turtle.goto(p2)
def main():
 # 求取点后，将超立方体点分为上下两个部分，两个列表
 a = [[120.71, 50], [50, 120.71], [-50, 120.71], [-120.71, 50], [-50, -20.71], [50, -20.71], [20.71, 50],
   [-20.71, 50]]
 b = [[120.71, -50], [50, 20.71], [-50, 20.71], [-120.71, -50], [-50, -120.71], [50, -120.71], [20.71, -50],
   [-20.71, -50]]
 # 绘制点
 turtle.pencolor("red")
 turtle.penup()
 for i in range(len(a)):
  turtle.goto(a[i])
  turtle.down()
  turtle.dot(10, "red")
  turtle.penup()
 for i in range(len(b)):
  turtle.goto(b[i])
  turtle.down()
  turtle.dot(10, "red")
  turtle.penup()
 # 绘制六边形直线
 for i in range(6):
  if i <= 4:
   drawLine(a[i], a[i + 1])
   drawLine(b[i], b[i + 1])
  else:
   drawLine(a[i], a[0])
   drawLine(b[i], b[0])
 # 绘制竖直线
 for i in range(len(a)):
  drawLine(a[i], b[i])
 # 绘制斜线
 drawLine(a[6], a[0])
 drawLine(a[6], a[2])
 drawLine(a[6], a[4])
 drawLine(a[7], a[1])
 drawLine(a[7], a[3])
 drawLine(a[7], a[5])
 drawLine(b[6], b[0])
 drawLine(b[6], b[2])
 drawLine(b[6], b[4])
 drawLine(b[7], b[1])
 drawLine(b[7], b[3])
 drawLine(b[7], b[5])
 turtle.done()
if __name__ == '__main__':
 main()
 pass

运行结果：
