旋转 3D 图

一个非常简单的关于三个轴旋转的 3D 图动画。

有关 3D 图动画的另一个示例，请参阅为 3D 线框图制作动画。

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import axes3d

fig = plt.figure()
ax = fig.add_subplot(projection='3d')

# Grab some example data and plot a basic wireframe.
X, Y, Z = axes3d.get_test_data(0.05)
ax.plot_wireframe(X, Y, Z, rstride=10, cstride=10)

# Set the axis labels
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z')

# Rotate the axes and update
for angle in range(0, 360*4 + 1):
    # Normalize the angle to the range [-180, 180] for display
    angle_norm = (angle + 180) % 360 - 180

    # Cycle through a full rotation of elevation, then azimuth, roll, and all
    elev = azim = roll = 0
    if angle <= 360:
        elev = angle_norm
    elif angle <= 360*2:
        azim = angle_norm
    elif angle <= 360*3:
        roll = angle_norm
    else:
        elev = azim = roll = angle_norm

    # Update the axis view and title
    ax.view_init(elev, azim, roll)
    plt.title('Elevation: %d°, Azimuth: %d°, Roll: %d°' % (elev, azim, roll))

    plt.draw()
    plt.pause(.001)
