Whatever it is, it looks sweet and tasty!

Nice.
Let me guess... An isosurface with cyclical perturbation.

The faceted texture makes it look like a mesh. I was fooled.

Make it out of jello? :D
And also know that related to Jello, sin (b) / tan (b) = . . . ?

I wish! I couldn’t come up with a way to get rid of the infinite
gradient of the ‘object’ pattern on the object’s boundary without
ruining it in the process, so I made do with a ridiculous number of thin
slices of the object rotated appropriately.

Because it's a giant mess. You can do it, and it will be a bit slow, but here's
a link for you:

Thanks, but my goal was to get an arbitrary POV-Ray object—like a text
object consisting of a single theta—into an isosurface, so it could then
be transformed non-linearly at will. Of course, that’d require a
generic way to make up a smooth transition, with a finite gradient, from
the outside to the inside, to replace the ‘object’ pattern’s jump from 0
to 1 at the boundary.

Yes, sorry - I think I botched that reply.
Bill Pokorny helped me along doing the same thing a while back, and here's one
of the files related to that. Feel free to ask any questions if the code
(mostly his) is unclear.

Thank you very much. I guess I have a lot to learn before I face this
problem again.

No worries. I tend to find myself in the deep end of the pool a lot. :D
The trick there is that since it's a discontinuous function with an infinite
gradient, one just inserts a user-made smooth gradient to join up the 2 regions
of the function. And then the isosurface method that you want to use works just
fine.
