[vtk-developers] vtkHyperOctree Deep Copy

[Philippe Pébay]

Hello Trevor,

Yes indeed, because I have not yet written a replacement for this class. I
need to look into it. In the meantime I am attaching a paper which we wrote
for the 21st International Meshing Roundtable and that explains several
aspects of the hyper tree grid.

Best,
Philippe
