[Paraview] ParticlePathLines Filter

[Biddiscombe, John A.]

Erratum

. The ParticlePath filter does NOT work for this kind of data.

The absence of the word NOT being quite important in the context!

The vtkTemporalPathLineFilter does not need to be attached to a stream tracer at all. It was developed for use with any particle dataset, (I just happened to use it with the temporal stream tracer as well and put that in the docs as an example). It is a general purpose filter for joining points up as time evolves and also allows you to provide a selection of points to use to subset the trails produced. The ParticlePath filter does work for this kind of data.
It's true that the Trails filter did not support particles jumping between processes in parallel, but why you would remove this filter is beyond me. Can the support for particles across process boundaries be added to the Trails filter?

I just tried the vtkTemporalPathLineFilter in 3.98 and some of the options seem to have disappeared. I will have to get it working again and submit a patch.

Hi, Christian,

   The old ParticlePathLine filter is replaced by ParticlePath filter.  Unlike the old one, you do not have to attach it to a particle tracer.  Also make sure you set the "TerminationTime" parameter to the largest possible time.

   I have written an article about this work: . http://www.kitware.com/source/home/post/76

   Let me know if this works for you.

thanks,

Leo

Hello,

in Paraview 3.98 the ParticlePathLines Filter is gone away. We use this to show the trajectory of simple particle data (x,y,z), based on ID. Is this intended ?

I got it back by copy & paste the proxysource from filter.xml in 3.14 (line 6679++) to 3.98. Would it be possible to add back the old ParticlePathlines Filter (with single inputsource and Pathline & Particle as output) in 3.98 because I love the webGL scene export in the new Paraview.

Thanks,
Christian
