[vtkusers] Unstructured grid to structured grid?

[chrism]

Is it possible to (easily) convert an unstructured grid to a structured grid
(Image data)?

Is unstructured -> polydata -> image data  the only way? If so, how example
(http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/DataSetSurfaceFilter ??)

Ultimately, the unstructured grid represents a topography, and I am looking
to 'rasterize' it for use in a GIS.
