If Isosurfaces where using complex shapes as containers, it wouldn't be 
as efficient, because the intersection tests that are supposed to save 
you a lot of function evalutations would take a lot of time.
Instead of a tube, you should try to fine tune the appropriate long box 
which would contain it.

But anyway, isosurfaces take a lot of time ... unfortunately
