appropriate graphics Lib?

Just realised (I responded to Bob earlier off list saying PyOpenGL should
work) that I should mention OpenGLContext (the testing/demo/learning context
for PyOpenGL).  With the absolute latest version of that (i.e. a CVS version
from today) you could do this by:

Create IndexedFaceset Objects (likely with textures) for each object
Put each IFS inside a Transform object with a name property
Register a mouse-click handler for each name in which you're interested

Then drop the scenegraph into one of the "testing context" objects (see the
tests directory for a raft of samples) and you're off to the races using
GLUT, PyGame or wxPython as your external GUI.

Enjoy,
Mike

pygame might not be the best fit here. it does have code to draw
irregular polygons, but you'd need to do your own intersection
tests for them. (although if you only care about bounding-box
type selection it could be your friend)

i hear tkinter has a pretty powerful canvas widget that i
supports these things. i'm guessing wxPython would have
something like that too.

pyopengl can also do selection, but it'll be more complex
than doing it with one of these higher level canvas widgets
you get with some gui's
