<div>It sounds like the particles you are extracting are different from one time step to the next. As you have probably guessed already, the Temporal Particles To Pathlines filter assumes that the particles are consistent from one time step to the next. If
the number or order of particles changes, then the filter will draw lines between different points.</div>

</div>
<div><br>
</div>
<div>You need to make sure the particle pathlines filter can uniquely identify the particles from one step to the next. Try first running the Generate Ids filter
<i>before</i> doing the extraction. Then in the properties for the particle pathlines filters, select the variable Ids for the Id Channel Array. That might do the trick.</div>

<div>Thanks Ken! that is exactly what I'm looking for. <br>
<br>
I've been playing around with it and it works very well when I apply the filter directly to my data set. But when I try to extract a region and then apply it, the particles are jumping around causing the pathlines to be incoherent. I guess that it's reading
the wrong particle at the next step. I've been using the threshold and extract selection filters to get to the region I need. Is there a better way to look at a section of particles without this happening? The input data doesn't have a particle key/ID or anything,
which may be some of the problem.<br>

<div dir="ltr">Yes animating them is no problem. What I would like to see is the path that the particles take over time, visualized as a pathline. Visualizing the location of a particle at one point in time is not what I'm after, which is what I see with the

<div>Dear Paraview Community,<br>
<br>
</div>
I am trying to visualise pathlines for my particle data. I have a vtk file with point coordinates as input.<br>
<br>
As an example this is one input file for just three particles. With a collection of these, is it possible to view the movement of these particles over time?
<br>
<br>
# vtk DataFile Version 4.2<br>
Particle data from file output.0 at time 0 ms<br>
ASCII<br>
DATASET POLYDATA<br>
POINTS 3 double<br>
0 0 1<br>
2 0 0<br>
1 1 2<br>
<br>
<br>
<br>
</div>
There's a few temporal filters, and I've had a play with them but they currently produce errors for me, resulting in nothing shown or paraview crashing. I have looked through the archives, and it seems there might have been a way to do this in an old version,
but not right now?<br>
<br>
</div>
Thanks<br>
Tim<br>
