[vtkusers] vtkOBBTree (and other tree) levels

[David Doria]

In this example:
http://www.vtk.org/Wiki/VTK/Examples/DataStructures/VisualizeOBBTree

I am trying to tell it to generate 6 levels of the tree.

I tried this:
obbTree->AutomaticOff();
obbTree->SetMaxLevel(6);
obbTree->BuildLocator();

but

std::cout << "Generating " << obbTree->GetLevel() << " levels." << std::endl;

outputs "2".

Also, in this example:
http://www.vtk.org/Wiki/VTK/Examples/DataStructures/VisualizeKDTree

Although it says it is generating 8 levels, all of the visualizations
seem to be simply the bounding box. How would one show the levels of
the tree?

Thanks,

David
