Hi ,all
 Happy New Year!
 I want to use vtkPointPicker to pick out the requested scalars attached to
a  PolyData  dataset.
 First, the method GetPointId() in  vtkPointPicker returns the point Id of
the picked one (through the
 mouse) ;Second, Polydata->GetPointData()->GetTuple(id). However , I cannot
get the correct data.
 It seems the GetTuple() method is obsolete .

 Anybody can help ?
 Any idea will be greatly appreciated .
