[Matplotlib-users] 3D surfaces and scatter plots have weird alpha behavior?

2010-10-04 Thread Erik Tollerud
I've noticed some odd behavior in the mplot3d toolkit when using scatter3D with plot_surface. What I want to do is generate the surface with an alpha level of 0.5, such that any points that are between me and the surface should come out fully opaque, and any points behind the surface should be

You're right - if I just change the surface to be opaque, some of the scatter points randomly disappear and reappear depending on camera angle. So how does it decide which points are behind/in front of the surface, then? I can't figure out any obvious pattern... And is it possible to use the
