Edit: After doubling the amount of lifetime experience with paraview or vtk since my last email, I think what I ought to do is create a filter that does a single iteration of shape deformation. Then I'll create a script that alternates "calling this filter" and rendering 500 times or so.
Let me know if that sounds incongruous with how Paraview works. Background Idea:The points on the initial sphere should deform in a way that minimizes the total 'energy' of the blob: edges should coincide with sharp contrast in the background volume; surface normals should be minimial.
