我想知道如何交互式地旋转一个三维图形,就像this视频中描述的那样(无论是从上方、下方、右侧还是左侧决定视角)。我可以在Spyder或Jupyter Notebook中生成一个三维图形,但之后它仍然是静态的,我无法与之交互并旋转/改变视点的角度。
这是代码:
这是代码:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.ticker import LinearLocator, FormatStrFormatter
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
scale = 8
# Make data.
X = np.arange(-scale, scale, 0.25)
Y = np.arange(-scale, scale, 0.25)
X, Y = np.meshgrid(X, Y)
Z = X**2 + Y**2
# Plot the surface.
surf = ax.plot_surface(X, Y, Z, cmap=cm.coolwarm,
linewidth=0, antialiased=False)
# Customize the z axis.
ax.set_zlim(0, 100)
ax.zaxis.set_major_locator(LinearLocator(10))
ax.zaxis.set_major_formatter(FormatStrFormatter('%.02f'))
# rotate the axes and update
for angle in range(0, 360):
ax.view_init(30, 40)
# Add a color bar which maps values to colors.
fig.colorbar(surf, shrink=0.5, aspect=5)
plt.show()
