Summary

0013004: composite data set iterator seems buggy with vtkOverlappingAMR

Description

If you run the following code snippet,

  vtkNew<vtkAMRGaussianPulseSource> imageSource;
  imageSource->Update();

  vtkOverlappingAMR* amr = vtkOverlappingAMR::SafeDownCast(imageSource->GetOutputDataObject(0));
  vtkCompositeDataIterator * iter = amr->NewIterator();
  iter->InitTraversal();
  while ( !iter->IsDoneWithTraversal() )
    {
    vtkAMRBox box =amr->GetAMRBox(iter);
    vtkUniformGrid* grid = vtkUniformGrid::SafeDownCast(iter->GetCurrentDataObject());
    assert(grid);
    int numCells = grid->GetNumberOfCells();
    cout<<"AMR box info: "<<"level "<<box.GetLevel()<<", Block: "<<box.GetBlockId()<<endl;
    iter->GoToNextItem();
    }

You get the output:

AMR box info: level 0, Block: 0
AMR box info: level 0, Block: 0
AMR box info: level 0, Block: 1

Notice that the first and the second block has identical (level, block) pair. This is not right.

Notes
(0028364) George Zagaris (developer) 2012-03-15 17:18	This is fixed and a topic is pushed to gerrit for review. See T260amr-i: amr-iterator-fixvtkOverlappingAMR::GetAMRBox internally downcasts to vtkUniformGridAMRDataIterator which has access methods to the CurrentLevel and correctly sets the Level of the AMRBox. The AMR box is now correctly constructed.
