Now let's set the projection to '3d', set the range for the viewing angles and disable pad_aspect (as it doesn't play nicely with animations).

autofig.gcf().axes.pad_aspect = False
autofig.gcf().axes.projection = '3d'
autofig.gcf().axes.elev.value = [0, 30]
autofig.gcf().axes.azim.value = [-75, 0]

anim = autofig.animate(i=times, tight_layout=False, 
                       save='phoebe_meshes_3d.gif', save_kwargs={'writer': 'imagemagick'})
