python 3d绘图旋转_python – 如何在matplotlib中旋转3D表面

根据我的评论：

import mayavi.mlab as mlab

import numpy as np

x,y = np.mgrid[-1:1:0.001, -1:1:0.001]

z = x**2+y**2

s = mlab.mesh(x, y, z)

alpha = 30 # degrees

mlab.view(azimuth=0, elevation=90, roll=-90+alpha)

mlab.show()

import numpy as np

from matplotlib import pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

from math import sin, cos, pi

import matplotlib.cm as cm

fig = plt.figure()

ax = fig.add_subplot(111, projection='3d')

#creating grid

y = np.linspace(-1,1,200)

x = np.linspace(-1,1,200)

x,y = np.meshgrid(x,y)

#set z values

z0 = x**2+y**2

# rotate the samples by pi / 4 radians around y

a = pi / 4

t = np.transpose(np.array([x,y,z0]), (1,2,0))

m = [[cos(a), 0, sin(a)],[0,1,0],[-sin(a), 0, cos(a)]]

x,y,z = np.transpose(np.dot(t, m), (2,0,1))

# or `np.dot(t, m)` instead `t @ m`

#label axes

ax.set_xlabel('x')

ax.set_ylabel('y')

ax.set_zlabel('z')

#plot figure

ax.plot_surface(x,y,z,linewidth=0, antialiased=False, shade = True, alpha = 0.5, facecolors=cm.viridis(z0))

plt.show()
