I wrote a filter called vtkVoxelizePolyData that converts a PolyData
to an ImageData. It should be easy to extend to converting an
UnstructuredGrid to an ImageData. Of course, you will lose most of the
information, and end up with an approximation (how good depends on the
fineness of the grid) of the points.

It is available here:

Please let me know if this is what you were looking for and if you
have any questions.

Thanks,
