[vtk-developers] vtkGeometryFilter

[Andreas Buykx]

Hi all,

I have a vtkUnstructuredGrid containing 50 vtkLine cells and 26 vtkHexahedron cells. The vtkHexahedrons are stacked, and the vtkLines form two (coincident) lines running through the middle of the stack.
When I feed the grid to the vtkGeometryFilter, the resulting celldata arrays are shorter than expected by 50 tuples.

I've been looking at the code of vtkGeometryFilter but cannot understand how this could happen.

Any help is greatly appreciated!

Thanks,
Andresa
