No OpenGL. The 3d graphics all goes through the same layering engine as the
2D plots. They aren't real 3D plots but rather what I like to call "2.1D"
plots. A single point of a 3D element is chosen to determine how to layer
it with everything else. So, it is very easy to get visualization
artifacts, especially with polygons.
Do this from python:
import matplotlib
import mpl_toolkits.mplot3d
print matplotlib.__file__
print mpl_toolkits.mplot3d.__file__
And tell us what that returns.
Cheers!
