I again started making some experiments with isosurfaces and radiosity,
now with a new faster computer that's much more fun than before, but still
quite slow.
The isosurface function is fairly simple, a 'blob' from a plane and a
sphere with an agate pigment function added.
The radiosity quality settings are quite high, probably could reduce count
to some extend without visible artefacts. The scene took 52 hours to
render at this size, statistics showed an incredible amount of 105 billion
DNoise calls, again a sign that current isosurface code is far from being
efficient with slow isosurface functions.

That's very realistic! Looks like some sort of mineral deposit from a
hot spring.

Very very impressive. It's amazing how good a "simple" isosurface can look :)
Can you post the source please? I'd love to have a look at the isosurface and
radiosity settings.

Agreed.

Except mineral deposits don't hover in mid-air!

No less than incredible. A *real* beautiful render.

Who threw that rock?

Maybe, but there isn't any water around...
For rocks, it's much too smooth, probably. Will have to work on that...
