This example shows how to use 2d plots in a 3d plot:

I don't see a reason why this can't be implemented. It is probably pretty
simple to change the surface plot code to use a polar grid instead of a
rectangular grid. Of course this won't change the look of the rectangular
axes, but maybe that is not a problem.
I invite you to take a shot at
There is an uncommented, and therefore undocumented function:
axes3d.view_init(elev, azim)

Interesting, but I think subdividing triangles like this is unnecessary. For
most cases, when one triangle completely covers the other, all that is required
it to Z order the triangles. This is what mplot3d does already. The only case
we have yet to handle is when one triangle pierces the
I also agree with Reinier. I want my 3d plots to look as close as possible to
my 2d plots. Because mplot3d uses so much of the same matplotlib core, this is
trivial. As Friedrich mentioned, the mplot3d code is actually pretty small.
To me, that is a great feature. I found the mplot3d code

The RectangleSelector has parameters for the min span in the x and y directions
of the rectangle. The units of these are the axes units. It would be nice if
there was an additional similar min size requirement, but in units of pixels.
This way it would be independent of the axes scale.
