[Paraview] Problem displaying only point data

[David E DeMarle]

Ah, I see, the spreadsheet view says that your cell types are all "Empty"
instead of "Vertex". You can confirm that by "file->save data"ing the file
out as vtu ascii and you'll find:
"        …
        <DataArray type="UInt8" Name="types" format="ascii" RangeMin="0"
RangeMax="0">
          0 0 0 0 0 0
          …
"
inside. And from vtkCellTypes.h 0 means VTK_EMPTY_CELL. So I suspect
something is going wrong where you are trying to write them all out as
1=VTK_VERTEX.

In paraview you could use the glyph filter (Glyph Type=2D, secondary Glyph
Type = Vertex) to correct for that, but you should find out what's going
wrong in the exporter if you can.
