In general POV takes 1 or more files as input and outputs an
image to a file. On most systems this would be too slow to run in
real time.

Pre-render all the frames, load them into memory, then "flip" through the
frames based on if the ball should be rolling left or right.

In Beta 17 there is a real time feature in testing, however this
is for rendering multiple views of the same scene, without re-parsing,
no objects can be moved, just the camera view. The camera is set by
defining multiple cameras in a scene, the output is passed as a message
instead of writing a file.

Beta versions of POV will expire, so don't put too much time into it,
it probably will become more stable and useful before it reaches
actual release, which may or may not be in 3.7

I'm sure others could tell you more about the Beta features...
