[Paraview] particle traces from point data

[Joachim Pouderoux]

Alex,

Again, could you specify how you are loading your files?
If you open them as a file series, then your data should be considered as
temporal and the filter should work.
See https://www.paraview.org/Wiki/Animating_legacy_VTK_file_series
