[vtkusers] Picking without an Interactor

[Giancarlo Amati]

Well I siply use an instance of vtkPointPicker to pick points that are in 
the intersection between the camera and mouse position.
Yes it's possible to pick without an interactor. Read about vtkPointPicker 
and it's mother class vtkPicker. Lookat also theire examples on the web 
site.

Bye.
