Technically that surface isn't quilted, exactly. When you make a blanket
by securing the layers at single points you do that by tying. It's a less
secure technique than real quilting, where the layers are sewn together
along lines.
It seems like the BOSL2 texture library does collect patterns like this.

Wonderful textures, but how did you create these?
Is it with the 2 waves method?

Another question: I wonder if it is faster to do it with the 2 waves
method or SDF? E.g. with libfive integration in python.

Can you share some examples as to how this works?

Just something like abs(z - sin(x) - sin(y)) <= d/2, where d is the
desired thickness.
I don't have time to compile the python integration for now so I just
tried it with manifold sdf. The surface is not very smooth due to
marching cubes used. It is probably better to do it with the method in
BOSL2.

All the BOSL2 textures were created by hand, I'm afraid. I had a need to do things like knurling on some parts, and that generalized into textures. Since heightfields were insufficient to make some textures cleanly, I expanded the system out to allow more precise VNF based textures. I just made a bunch of standard textures that seemed useful. Textures can be applied to cyl()
s, rotate_sweep()
s, and linear_sweep()
s.
You CAN use the two-wave technique to generate heightfields or VNFs that are useable as textures, but you have to beware how many vertices you introduce.
The fact that you can generate the diamonds I originally needed for knurling via the 2-wave method was actually an interesting surprise to me, though it's far more expensive in vertex counts. The manually created heightfield texture for diamonds in BOSL2 is actually just [[0,1], [1,0]]
