[vtkusers] how to clip and cut DEM data?

[Karthik Krishnan]

DEM data is just 2D image data with the scalar values representing the
height field. So you do need to transform it to polygonal data to be able to
render it and then cut it.

See  IO/Testing/Tcl/dem.tcl for an example of how to transform it to a
polydata.
