It depends. Detailed meshes and heighfileds located in complicated scenes
takes large amount of memory while a few simple isosurfaces are very small.
Meny referrences to various places in large scenes cause swaping memory cache
a lot while small isosurface written by experienced user can be efficient. So
saying anything about majority of cases is wrong without considering specific
object/scene as it was already pointed out a few times.
