[vtkusers] topologically correct surfaces

[Bill Lorensen]

No, Marching Cubes only generates locally correct topology.

Perhaps you want a deformable surface. You can start with a sphere then evolve it using a 3D snake. itk, www.itk.org, has a deformable surface, although it may be a be immature at the moment.
