Hello list,
I know it is not recommended to use matplotlib for 3d plotting, but for a
while simple plots worked fine for me. This is not the case with actual svn
version and therefore my question is: Would it break at lost or cost much
effort to make the 3d-plot-examples of the Cookbook work?
if I try:
[1] import matplotlib.axes3d as p3
I get the error attached below.
Thanks for any advise in advance.
best regards Matthias

I'm not very familiar with how axes3d works, but just by looking at the number of transform calls and objects, it appears that it will take significant effort to update it. It was never one of the goals of the transformation refactoring to have that working. Personally, I'm +1 on removing axes3d.py to avoid confusion.
However, a motivated user could follow the information in API_CHANGES to update axes3d.py. I'd be happy to help if you got stuck, but I don't really have the motivation/mandate to do the whole thing myself.
Cheers,
Mike

I agree. This is overdue.

Mike, just a question about the new transforms backend -- can the input
dimensionality be greater than 2? (I realize functions to do so probably
don't currently exist, but the question is about the transforms
machinery itself.)

In theory, yes, but it's a completely untested theory. Each transform class has an input_dims and output_dims member that defines the input and output dimensions. So theoretically, you could create a perspective or orthogonal projection that maps from 3D to 2D.
