[Matplotlib-users] Matplotlib 3D: Remove axis ticks & draw upper edge border?

[Benjamin Root]

Sorry, those features are just not possible with the current design. The
code assumes that all rotations are done from the center. And the tick
marks aren't handled the same way they are in 2D graphs, unfortunately.
Also, the code has just three backing panels. It is possible to make one or
more of them invisible, but you can't add more panels. In fact, you
wouldn't want other panels to appear because it is assumed that these
panels will always appear behind any other artists. Any other panels would
run the risk of being composed incorrectly with the contents of the plot,
creating "Escher effects" -- visual paradoxes. Nothing is stopping you,
though, from putting in your own panel from a Poly3D or Patch3D object. In
fact, you can just create a Patch artist and put it through the 2d to 3d
converter function in mplot3d.art3d.

I would consider the current state of tick control to be buggy, and I agree
that effort should be spent fixing it. Having the ability to specify an
arbitrary point of rotation is an interesting feature and I wouldn't be
opposed to a merge request adding that feature.
