Nothing amazing in this picture. In fact the same picture can be obtained with
/scenes/objects/sor1.pov script. Only one difference - it is completly made
with isosurfaces instead of sor object.

It seems these are very complex functions, so that's impressive. If they are
parametric isosurfaces, I guess the render time hits the roof? But a nice
addition to include in toturials, maybe even the Pov3.5 example files.
Together with Ingo's parametric mesh macro, these sor's could be superior to
the old sor keyword, because these will never have holes / errors when they
render.

I've had an example of a parametric technique to achieve this sort of
effect on my isosurface tutorial page for quite a while

No, that's regular isosurfaces, not parametric{}. Render time is is
reasonably. Slower than traditional sor{}. IIRC this set of six objects took
two hours on my PII 233 with a lot of tasks. Note there is more than one
light_sources so it increase render time.

It was mainly designed for iso_csg library. Main adventage is that like other
isosurfaces it can be simple displaced.
