I ran into a similar problem a few weeks back with vtkStructuredGrid.

For the issue of a vtkUnstructuredGrid... I'll try to summarize what I
said in [http://public.kitware.com/pipermail/vtkusers/2005-July/080704.html]:
I stored 3-d chunks of connected points with an unstructured grid.
Every volume of space in my data was stored as a vtkVoxel cell. Since
each cell is unstructured, it doesn't matter where you set it up in
vtk as long as you have your 8 indices (to a points list) correct for
I had no luck with vtkMergePoints either.
Let me know if that helps you get started
