  Truth is it produced nothing. It parses just fine but
nothing appears. I also tried using 2D vectors. This did
produce a result exactly as one would expect. It produced
a single face of the box.
  How would Pov determine the inside of the object ? Would
it just take the normalized vector as it would a plane ?
