I am using python3. When I googled, it came out that I should write the following code to write a sphere with matplotlib. However, here we use matrices for x, y, and z as arguments to plot_surface. What kind of calculation does this do internally and plot the graph? If anyone knows, please professor. Thank you.
from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt import numpy as np fig = plt.figure() ax = fig.gca(projection='3d') # Make data u = np.linspace(0, 2 * np.pi, 100) v = np.linspace(0, np.pi, 100) x = 10 * np.outer(np.cos(u), np.sin(v)) y = 10 * np.outer(np.sin(u), np.sin(v)) z = 10 * np.outer(np.ones(np.size(u)), np.cos(v)) # Plot the surface ax.plot_surface(x, y, z, color='b') plt.show()
