You need to use the vtkPicker class.  I think the default 
vtkRenderWindowInteractor has the 'p' key bound to some picking routine, 
but you are not limited to that behaviour.  The class docs for the 
vtkPicker class (and the vtkPointPicker and vtkCellPicker subclasses) are 
pretty decent, although no examples are provided.

If you need more help after reading the doxygen docs, let me know.
