They can't mean that seriously (or perhaps they'll have to re-evaluate after
this contest). Why?! Well, there's PovRay (www.povray.org) a really good
freeware raytracer. If one would spend a little time of actually
transforming the input to PovRay (which is probably not that hard) you'd
blast anyone away. While this might spoil the fun there is certainly a point
in doing that and make practical reuse an issue here ;-)
