[vtkusers] vtkDecimatePro Bug

[Sebastien_MARAUX]

Hi

Whereas decimatePro is setup to preserve topology,
It issues a 90% decimated polydata with modified topology, 
where do I do something wrong (first decimation is quadric 
clustering) ?

 vtkDecimatePro *decimation2 = vtkDecimatePro::New();
 decimation2->SetInput(decimation->GetOutput());
 decimation2->PreserveTopologyOn();
 //decimation2->SetTargetReduction(0.5);
 decimation2->BoundaryVertexDeletionOff();
 decimation2->SplittingOff();
 decimation2->SetErrorIsAbsolute(1);
 decimation2->SetAbsoluteError(0);
 decimation2->SetMaximumError(0.0);
 decimation2->Update();

Thanks for any help
