Hi,
Animations of 3d scenes is a bit tricky, because set_data() functions
for wireframe and surface plots are not available. However, you can
still do it by creating new surfaces or wireframes every frame, and
removing the old one. I've attached an example that does this and will
be added to svn soon.
You could also rotate the 3d axes:
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
import numpy as np
plt.ion()
fig = plt.figure()
ax = axes3d.Axes3D(fig)
X, Y, Z = axes3d.get_test_data(0.1)
ax.plot_wireframe(X, Y, Z, rstride=5, cstride=5)
for angle in range(0, 360):
ax.view_init(30, angle)
plt.draw()
Regards,
Reinier
