[vtkusers] Picking individual polygons specified in a .vtk (POLYDATA) file

[Surajit Nundy]

Hello,
	I have a .vtk file which I can read, display (and pick ) whose header 
is below. I would like to be able to pick individual polygons from this 
dataset.  Unfortunately, when I display the data as a vtkActor whose 
input is a vtkPolyDataMapper whose input is a vtkPolyDataReader, I can 
only pick (using vtkRenderer.PickProp) the whole Actor.  My facility 
with vtk ends here.  Is there some way that I could pick the individual 
polygons in this dataset?

Thanks
Surajit Nundy
