<br> Happy New Year!<br> I want to use vtkPointPicker to pick out the requested scalars attached to a PolyData dataset.<br> First, the method GetPointId() in vtkPointPicker returns the point Id of the picked one (through the
<br> mouse) ;Second, Polydata->GetPointData()->GetTuple(id). However , I cannot get the correct data.<br> It seems the GetTuple() method is obsolete .<br><br> Anybody can help ? <br> Any idea will be greatly appreciated .
