Viewing Stereographic Projection of an Image

edit

I'm trying to write a program that takes an image and projects it onto a sphere that I can then view using 3dplot. I'm using pylab to read the image, numpy to put it into an array and then a stereographic projection to actually project it onto a sphere. I'm fairly certain the program is working correctly.

The problem I have is that 3dplot is not letting me view an image. The plot doesn't load. I tried the tachyon viewer, and I could get an image of my picture on a sphere, but I would prefer if I had the ability to rotate the sphere that 3dplot provides. Is there a better way to accomplish what I'm trying other than using pylab? I don't know much about other python imaging systems.
