[vtkusers] vtk append polydata

[Chiranjib Sur]

Hi Als,
This example might help you :
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filtering/CombinePolyData

When you are appending new data you are missing the information of the old
data with which you need to append.

I am doing it this way

appendPolydata->AddInputConnection( OldPolyData->GetProducerPort());
appendPolydata->AddInputConnection( NewPolyData->GetProducerPort());

appenPolydata->Update();
