Rather than giving away the answer, I think a lesson in fishing is in order.

Look into #debug and the debugging text stream, and expecially into the
str(a,b,c) function, and I think you'll find a way to work out the answer on
your own, in a few short, and very worthwhile, minutes. You'll then also
know how to explore a whole host of other POV questions on your own.

If you still run into trouble, why don't you post back on povray.newusers?
