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:
注:使用eclipse+pyDev结合Python3环境开发时,会提示:Undefined variable from import: penup及Undefined variable from import: goto等错误,无需理会直接运行仍可绘制出该图形。
