That's sort of how the povexport.py that is available for Vpython works
(though I use my own 'enhanced' version of the 'official' povexport.py, same
principle, handles some neglected and newer Vpython primitives, I release it
to the Vpython folks, might have needed a tweak here or there for their
purposes, nothing happens, 2 years later, another story)
 
Can you envision a way to make the pattern you are describing real time and
interactive?  

Maybe so, and maybe I can apply it.

Did he say interactive?

That's right, mouse clicks - am I a hypocrite or what. Or else middle
ground, middle ground.
