[Paraview] Trouble with DeepCopy()

[Adriano Gagliardi]

Dear All,

I'm executing the filter vtkPlotEdges. I pass in a vtkPolyData object and
receive a vtkMultiBlockDataSet object as output. My output data object is
also of type vtkMultiBlockDataSet, so I'm trying to perform a DeepCopy of
the temp object, but I'm receiving a segmentation fault. Can someone point
out what I'm missing here?

{

vtkMultiBlockDataSet *output = vtkMultiBlockDataSet::SafeDownCast(
outInfo->Get(vtkDataObject::DATA_OBJECT()) );

//polydata is a pointer to a populated vtkPolyData object.

std::cout << "Executing vtkPlotEdges..." << std::endl;
vtkPlotEdges* pe = vtkPlotEdges::New();
pe->SetInput(outputPoly);
pe->Update();

output->DeepCopy(pe->GetOutput());

pe->Delete();

}


Cheers,

Adriano
