Python編寫萬花尺圖案實例

Posted on by

小的時候大傢應該都玩過萬花尺，將筆尖放置萬花尺內不停的轉動，便可以畫出一幅精致的線稿圖，現在我們不用萬花尺，我們通過Python也能繪制出萬花尺圖案。

（一）代碼

#!/usr/bin/python# -*- coding: UTF-8 - *-
import mathclass PTS:
def __ init __(self):
self.x = 0
self.y = 0
points = []
def LineToDemo():
from Tkinter import *
screenx = 400
screeny = 400
canvas = Canvas(width = screenx,height = screeny,bg = ‘white')

AspectRatio = 0.85
MAXPTS = 15
h = screeny
w = screenx
xcenter = w / 2
ycenter = h / 2
radius = (h - 30) / (AspectRatio * 2) - 20
step = 360 / MAXPTS
angle = 0.0
for i in range(MAXPTS):
  rads = angle * math.pi / 180.0
  p = PTS()
  p.x = xcenter + int(math.cos(rads) * radius)
  p.y = ycenter - int(math.sin(rads) * radius * AspectRatio)
  angle += step
  points.append(p)
canvas.create_oval(xcenter - radius,ycenter - radius,
          xcenter + radius,ycenter + radius)
for i in range(MAXPTS):
  for j in range(i,MAXPTS):
    canvas.create_line(points[i].x,points[i].y,points[j].x,points[j].y)

canvas.pack()
mainloop()if __name__ == '__main__':
LineToDemo()

（二）實現結果

我們還可以通過修改不同的參數來實現不同的圖案轉化，大傢可以多試試，做出多種不同的效果圖。
