I'm not sure if the internal data built during the render
is suitable for your needs, but even if so you'd need to
modify the source code of POV-Ray to get at it.

Alternatively, you can divide the scene into cubes in SDL
and use the trace function to check if they're empty or not
(within some error margin). In 3.7 you could even write
the data out in a binary format (such as df3).
