[vtkusers] [vtk] reading vtkMultiBlockDataSet

[Tanaka Simon]

i think found the solution:


     vtkSmartPointer<vtkXMLMultiBlockDataReader> reader = 
vtkSmartPointer<vtkXMLMultiBlockDataReader>::New();
reader->SetFileName("vtkMultiBlockDataSetWriter_output.vtm");{
     reader->Update();

     vtkSmartPointer<vtkPolyData> linePolyData =
     vtkSmartPointer<vtkPolyData>::New();
     /* add some vtkLine to linePolyData */

     vtkSmartPointer<vtkMultiBlockDataSet> multiBDS_read = 
vtkSmartPointer<vtkMultiBlockDataSet>::New ();
multiBDS_read->ShallowCopy(reader->GetOutput());
multiBDS_read->(multiBDS->GetNumberOfBlocks(),linePolyData); // append 
one more block

     vtkSmartPointer<vtkXMLMultiBlockDataWriter> writer = 
vtkSmartPointer<vtkXMLMultiBlockDataWriter>::New();
     writer->SetFileName("vtkMultiBlockDataSetWriter_output.vtm");
     writer->SetInput(multiBDS_read);
     writer->Write();
