No, i meant to do the plants with the isosurface, just make the planted
parts a bit higher and more noisy.

It only means that it's 2d :-) meaning that it calculates the gradient in
a plane. Souldn't matter here, because usually you use something like:

isosurface {
  function { y - fnRMF(x, 0, z) - fnAdditiomalNoise(x, y, z) }
  ...
}

so you only use the RMF function on a 2d plane

Your construction is somewhat different, so i'm not sure if it works.
