They're not basalt, they're just.. columns. The image isn't meant to
look perfectly realistic and natural.
The vturbulence() suggestion is interesting, but I'd have to figure out
how it works first.

One problem you might explore is making the tops of the prisms slope in
various directions, everything I tried either gave hollow uncapped prisms of
very strange results.

Did you try intersecting the prisms with planes? Clipped_by would give you
hollow prisms for sure, but intersection should work....

Is this supposed to model a realistic natural formation, or is it your own
imagination? I've never seen anything like this.

They are, in fact, perfect hexagons.
You rotate and translate them like any other object. Since that seems
pretty obvious, I have to assume that I'm misunderstanding your question...

Cool!
Gee, by the time we have POV 5.0, it'll practically make your scenes for you.
Just slap together some features and you're bound to get something cool.
Of course, not to say you didn't put any work into it.

No, they are very very very miniscually warped by roundoff errors. ;)

My statements are definitive. Reality is frequently inaccurate. ;)
