通过Python绘制九种二次曲面的示例详解

>>> import matplotlib.pyplot as plt
>>> import numpy as np
>>> theta = np.arange(0,6.4,0.1).reshape(64,1)
>>> phi = np.arange(0,3.2,0.1).reshape(1,32)
>>> x = np.sin(theta)*np.cos(phi)
>>> y = np.sin(theta)*np.sin(phi)
>>> z = np.cos(theta)
>>> ax = plt.gca(projection='3d')
>>> ax.plot_surface(x,y,z)
<mpl_toolkits.mplot3d.art3d.Poly3DCollection object at 0x000001CECF13A730>
>>> plt.show()
