Rotating a 3D plot#

A very simple animation of a rotating 3D plot about all three axes.

See Animate a 3D wireframe plot for another example of animating a 3D plot.

(This example is skipped when building the documentation gallery because it intentionally takes a long time to run)

from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt

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

# 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
        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))
