[vtk-developers] vtkCubeSource bad topology

I'm sure that this won't be able to be changed for backwards
compatibility purposes, but shouldn't the cube source have 8 points
and 6 quads? It currently has 24 points (all of the corners are
repeated 3 times (each corner of each face is it's own
geometry/point). You can see this by running vtkFeatureEdges to view
the BoundaryEdges - all edges are boundary edges, when the cube,
supposedly being a closed mesh, should have zero boundary edges.

Is there any reason it is created like this?

Thanks,

David
