[Matplotlib-users] Diplaying 2D images in mplot3d

[Fabrice C. <kap...@ya...>]

Dear list,

I would like to display a 2D image in a mplot3d axe in order to combine 
it with a surface3D or a bar3d plot for instance. The effect I am 
looking for is similar to what can be seen in the bottom XY plane of 
http://matplotlib.org/1.4.0/examples/mplot3d/contourf3d_demo2.html, 
except that I would like to have a custom image instead of the filled 
contours.

I googled the subject and found only messages dating at best from 2010. 
These messages mentioned that the imshow() method did not work on a 
mplot3d. Indeed it does not.
The only alternatives offered by the googled answer to my problem were 
to switch to VTK or Mayavi. For one thing, I never managed to install 
VTK on my PC, and I already have other matplotlib figures in my wxpython 
application so I would really like to stick to matplotlib.

Does anyone have pointers as to how I could display a 2D image in 
mplot3d? Do I need to create a new artist in order to replace the 
non-functionning imshow?
I see that patch collections work fine in mplot3D. Would it be feasible 
to load an image and have it displayed as a patch collection (1 patch 
for each pixel)?

Any advice would be highly appreciated,

Fabrice
