I already feared that, maybe some internal gradient pattern would be
faster.

I don't think that can be compared since Ategeros is only about
heightfields so it's quite limited.  Of course adding some seperate
objects for trees could be quite good even for an isosurface landscape.  

I did not work much on Ategeros recently, also because isosurfaces offer
many things not possible with heightfields.
