[Paraview] Point Cloud in Ensight Case Format

[Berk Geveci]

It looks like you need to glyph the dataset. ParaView does not display
points that are not associated by geometry. The glyph filters creates
geometry (in your cae, you probably want a vertex per point)
associated with points. Apply the glyph filter to your dataset.
