小作品—用python画一朵美丽的玫瑰花

代码不是原创的，只是运行出效果。

刚开始导入这些代码可有能报错，需要安装cm  matplotlib

from mpl_toolkits.mplot3d import Axes3D

from matplotlib import cm

from matplotlib.ticker import LinearLocator

import matplotlib.pyplot as plt

import numpy as np

fig=plt.figure()

ax=fig.gca(projection='3d')

[x,t]=np.meshgrid(np.array(range(25))/24.0,np.arange(0,575.5,0.5)/575*17*np.pi-2*np.pi)

p=(np.pi/2)*np.exp(-t/(8*np.pi))

u=1-(1-np.mod(3.6*t,2*np.pi)/np.pi)**4/2

y=2*(x**2-x)**2*np.sin(p)

r=u*(x*np.sin(p)+y*np.cos(p))

surf=ax.plot_surface(r*np.cos(t),r*np.sin(t),u*(x*np.cos(p)-y*np.sin(p)),rstride=1,cstride=1,cmap=cm.gist_rainbow_r,

linewidth=0,antialiased=True)

plt.show()
