  I believe that what he meant is that he wants to take *any* given object,
regardless of what it is, and bend it. He just gave two illustrative
examples to demonstrate the effect he wants, not meaning he actually
wants to bend precisely these two objects in question.
  Isosurfaces are not really the answer (besides, technically what you
are proposing is not *bending* the isosurface, it's just creating another
isosurface which looks like a bent version of the original).

  The general answer is that it's not possible. See more on this at:
