I don't know how to do this: I would like a torus filled with a pattern
similar to the spherical or cylindrical patterns, i.e. going from 1 (at
the small radius centre) to 0 (at the small radius boundary). Any idea?

warp ? toroidal

Not entirely what I expected but I need to experiment with this. It
comes very close to what I want.
Thanks!

Not what was asked.
This will wrap a pattern around a torus.
The question is about a pattern returning 1 at the major radius of a
torus and dropping to zero at minor radius. Similar to spherical,
cylindrical and planar.
Curently, there is no "toric" pattern. It can be done using a function
as a pattern based on the torus equation.

one could start with a cylindrical pattern and warp it in place to have
the asked pattern.

Yes, but used as a density pattern, it has the interesting effect of
showing swirling matter through the torus. Not my initial image in
p.b.i. because I added a turbulence warp.

I need to test this. It came to my mind too.
