  This is completely unrelated to the issue in question, but as you are
wanting to make a good object-oriented implementation, I would like to
note that 'void*' is usually against OO principles and extremely rarely,
if at all, needed in a well-designed OO program. (I have never used it
in my programs, that's for sure.)
  (Of course if you are doing this as a POV-Ray patch, you might need to
use it in some places, as the POV-Ray source is still basically C, where
using 'void*' is more common.)

  By the way, isn't that a rather large value for epsilon? Such large value
can introduce visible artifacts.
