What exactly is it you wish to achieve within POV-Ray?

As far as I can see, if you use an external heightfield,
its either seamless or not, and if you have some kind of
function for the terrain you don't really need tiles as
you already get arbitrary extent and resolution?

But it's an interesting construct, I never thought of
projective planes in terms of landscape tiling - I was
actually thrown off track for a bit by the unusual array
directions but I'd still say its a projective plane ;)
