I must admit I didn't know about hg-pov's mesh tools - I was aware of the fork,
but didn't realise what it included. Very interesting!

My macro works in POV-Ray 3.7/3.8, and indeed any version of POV-Ray based on
these (e.g. UberPOV, which I mostly use these days). It looks like one could do
the same things in hg-pov by chaining successive meshes together. The marching
cubes algorithm allows for a greater range of base shapes than my macro, and
will obviously be much faster.

The only advantage my macro appears to offer is the inbuilt uv-mapping that
allows separate texturing of the displaced regions (I couldn't immediately see
how hg-pov's mesh tools would permit this, but it might be possible).

More choice for everyone!
