  Actually the reason why the object disappears is not floating point
inaccuracy but because POV-Ray drops the object if it's too far away.
  Naturally POV-Ray does this in order to avoid the accuracy problems,
but it's not the accuracy which is dropping out the object but POV-Ray.
There's a reason for this: It's very possible that if POV-Ray didn't
drop the object, it might render with bad artifacts.

  See http://tag.povray.org/povQandT/languageQandT.html#largescaleproblems
for details.
