I've rushed through an update of my Isosurface Tutorial to include the
isosurface syntax used in POV-Ray 3.5 beta 1.
All the example source files are now available in both MegaPOV and POV
3.5b1 formats. The main text now follows 3.5b1 syntax with the
significant MegaPOV differences highlighted.
Absolute beginners to isosurfaces would benefit by looking through the
isosurface tutorial pages included in the 3.5b1 documentation before
digging too deep into my pages.
I'm sure that there are still lots of new tricks that can be done with
3.5b1 that were not possible with MegaPOV, and I'll be updating the
tutorial as I find them.
It's at <http://www.econym.demon.co.uk/isotut/index.htm>

While I was looking at http://www.econym.demon.co.uk/isotut/nfunc2.htm ,
the second item claims to be a quantum-mechanical function. I'm a
physics student myself, and I don't recall ever having seen it; the
image above it, however looks VERY familiar! A 3-d version of an
electron density function. Someone's gotten confused, but don't worry;
it's not you.

This answers my questions about surface deforms!!
one more thing, just for interest sake - is it at all possible to have
isosufaces with interiors? for instance a waterblob floating in space with
ior?
I would suppose not, but it would be nice to know if it can be done...

Why do you suppose that isosurfaces have no interior?

I get that from iso-*surfaces*
just a guess, though

OK,
I see now that they do have interiors.
Thanx

All objects in POV-Ray are surfaces. There are no solid objects.
(Don't confuse "hollow" with this. It's a completely different context.)

OK...
All tutorials about isos I read give me more Questions than Answers. Is it a
criminal act to understand those things not? :p
But this is no criticism. I guess I would laud it if i had a brain :))
