Problem is that `PVGeometryFilter` uses `vtkDataSetSurfaceFilter` to generate the grid geometry. However, this filter only generates quads or triangle strips for >=2 dimensional grids.
Suggestion for a fix: use `vtkRectilinearGridSurfaceFilter` and `vtkStructuredGridSurfaceFilter` when dimension is < 2.
