They monitor these groups,
On the lookout for Ken,
But that Povray Punster,
Has struck once again.

EEEeeeikes! I still have that migraine, dude, all I can think of is Ice
Packs! But if you think it will help I would be anxious to see it. I was
planning on making layers of toroidal densities and laying some crackle
media on them.

I stand corrected. Not with a single sor, that is. You can make a
torus using CSG and two sors.

I am having the same problem with this that I have had with other
formulas. It appears to make an intersection of two spheres with a sphere
punched out of the middle.
This make a good torus in an Isosurface statement, but chops off the
inner curve in media. I tried laying it over a spherical and cylindrical
density and playing with the density in a color_map but all that gave me was
a faded convex edge (see p.b.i.)
Did you have any better results with media?

Never mind....
...contain it in a torus of the same size and then use color_map to take
away rings....

That's what I do, or you can try (if the 'min' function works for
isisurfaces)
min (1, sqrt( y*y + (sqrt(x*x+z*z)-1)*(sqrt(x*x+z*z)-1) ))
John sent mi this function per my request for a toroidal 'wood'
pattern, so it's not clipped like the cylindrical or spherical
patterns are. The change applied above should make it a unity toroidal
pattern clipped to 1.

Difference between the "outside" part - shaped a bit like a flattened
sphere - and the "inside" part - shaped somewhat like a one-sheet
hyperboloid.
