我正在使用tkinter生成二维形态图。我发现它非常慢。例如,这个脚本在我的8核Xeon上花了将近10秒钟:
#!/usr/bin/env python3
import random
import tkinter as tk
A = 3.419384662527591
B = 2.0158889752347022
C = 19.479697084985673
D = 61.006212908774614
F = 1.3449991745874286
G = 1.9590223710983992
H = 5.129501734860241
WIDTH = 800
HEIGHT = 600
class Morphogenic(tk.Frame):
def __init__(self, root):
tk.Frame.__init__(self, root)
self.canvas = tk.Canvas(width=WIDTH, height=HEIGHT, borderwidth=1)
self.canvas.pack(side="top", fill="both", expand=True)
def rand(self):
A = 3 + random.random() * 10
B = 1 + random.random() * 5
C = 1 + random.random() * 20
D = 1 + random.random() * 200
F = 1 + random.random() * 2
G = 1 + random.random() * 20
H = 1 + random.random() * 20
def draw(self):
points = [0] * HEIGHT
points_space = [0] * HEIGHT
points_energy = [0] * HEIGHT
w = WIDTH
h = HEIGHT
min_x = 0
last_x = 0
last_y = 0
while min_x < w:
min_x = w
lrand = 0
for y in range(1, h):
points_space[y] = points_space[y] + \
(points_space[y - 1] - points_space[y]) / F
for y in range(0, h):
lrand = lrand + (random.random() - 0.5) / C
new_point = points[y] + points_space[y] + lrand
points_space[y] = (new_point - points[y]) + \
points_energy[y] / G
points_space[y] = points_space[y] + (A - points_space[y]) / D
points_energy[y] = points_energy[y] / H
if (points_space[y] < B):
points_energy[y] = points_space[y] - B
points_space[y] = B
points[y] = points[y] + points_space[y]
if (min_x > points[y]):
min_x = points[y]
self.canvas.create_line(last_x, last_y, points[y], y)
last_x = points[y]
last_y = y
if __name__ == "__main__":
root = tk.Tk()
m = Morphogenic(root)
m.pack(fill="both", expand=True)
m.rand()
m.draw()
root.mainloop()
tkinter对于这种工作来说太弱了吗?我应该看一个不同的2D库吗?

我也使用Tk作为应用程序。
这是一个使用XML文件自动生成GUI的应用程序,TK太慢了。
我转向PYside并对此感到非常高兴。它不像Tkinter那么容易使用,但它更快,并且具有很多可能性

您的代码创建了超过150,000行。这开始推动canvas小部件的性能。它可以很容易地处理成千上万的物品,甚至成千上万的物品。 150,000件物品比它设计的要多一点。
