As someone else already pointed out: POV-Ray is a renderer, so it's not
its task to export scenes. (To make it easier to write a parser for
modellers and converters I suggest using something like ANTLR for
POV-Ray 4.0.)

(This file has been generated with megapov.)

Here I must confess that I don't know what this is in this context.
Or are you talking about mesh refinement for finite element methods?
