I actually wrote this a while ago, and at that time I think I tried with an
isosurface but can't remember what was not working (on the top of my head I'd
say it was unpractically slow ?)

Thanks :) This is kind of a classic actually, a so-called Seifert surface for a
torus knot. I isolated the problematic part when asking this question but if
you're curious here is what I actually wanted to plot (using jr tweaks ! Thought
I get an error from the +ac0.99 option, I'll try to figure out why).
