A rapid test here :-)

It is unexpected fun to me.
It is a bit like a (shrub)maze.
Not bad.

Simply, I could not resist;)
isosurface {
function { f_result2(x,y) }
contained_by { sphere { <0,0,0>,5 } }
threshold 0.75
max_gradient 1000
pigment { color Cyan }
rotate <60,0,0>
scale 5
}
Since the functions given by And are constant in direction z, with an
isosurface the container will limit the functions in this direction. So,
I thought a sphere would look better than a box as container.
Best regards
Michael

Now that's pretty cool - it almost looks like one of those sci-fi "city-planets"
kinda like "Dark City" or something like that.

LOL! Yes, even better!

This looks still planar mapping.

Sorry, but I have no idea, what "planar mapping" could mean.

I mean it is not a spherical wrapping
