Good luck!

I am trying to use vtkPointPicker to select points on a given actor.  I am
confused as to what initialization steps are necessary to use
vtkPointPicker.

I do the following:
           create an instance picker of vtkPointPicker
           add picker to the renderWindowInteractor using iren->SetPicker()
           and then try to do picker->GetPointId() which returns -1.

What am I missing?  Is there some sample code somewhere to do this?

Thanks,
-Sarah
