I'm looking for a way to use matplotlib's 3D plotting
capabilities to display a flat image (a png or tiff) in 3D
space for some visualization I'd like to do.
The documentation is not very helpful,
is this even possible?
Here's a post that shows how to do what you're looking for.

I want to plot 2d slices of 3d data as shown in this figure (). Is it possible to do it in python, preferably using matplotlib? I am hoping to have someone provide me with guidance, or a sample code is even better. I appreciate any help anyone can provide.
As far as I know Matplotlib so far can not handle the intersecting planes correctly.

You can try to use mayavi or plotly. In particular check out this link
I am having a 2d numpy array serving georeferenced information like a radar image or a temperature field. I know the coordinates of all points and can define the bounding box in EPSG:3857.
What is the fastest way to plot this data into a tms tile pyramid?
A well known solution is to plot data as a geotiff and use gdal2tiles but this is very slow for hgh zoom levels >10.
I hope anyone can recommend a software doing this or can provide a code snippet. Thanks a lot!
The left image was drawn using MATLAB and color changing is smooth, beautiful! The right image was drawn using Python matplotlib hist2D and it is sharp.
Is there any method to make it more beautiful like MATLAB's?
I have an array of points (x,y,z) that I would like to animate in 3D using Mayavi (Python). I am currently using a Plot3D command to plot all of the points simultaneously (modeling the movement of a particle), but would love some help on the animation.
Thanks!
Matplotlib offers a lot of possibilities for animation. Have a look at the specific routines for animation. In particular, there's a specific example for 3D plotting.
There are quite a few tutorials on the 'web. Eg. Matplotlib Animation Tutorial and Animated 3-D Plots in Python
Using basemap it's easy to plot a set of coordinates, like so:
x, y = m(lons, lats)
m.plot(x, y, 'go')
but would it be possible to use an image instead of the green circle ('go')? I didn't find a direct way of doing this from the documentation.
So, let's clarify this a bit: I'm using a map generated with basemap as a background and would like to plot some .png images on top of it instead of the regular plain markers.
If you want to draw .png images then you should try http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
