Hello,
I have a series of particle data files that I have written using the VTK XML
PolyData file format (.vtp, I guess). I can use those to display the actual
particles just fine with glyphs, but I'd like to also see a pathline being
displayed for particles. I am therefore trying to use the 'Particle Pathline'
filter.
The particles are simulated in a flow field, where new particles come in and
older particles leave the system at every timestep. I therefore also have a
'point data' array called "ParticleID" which tags a unique ID to each particle
(starting with a zero index). It is defined as such:
<PointData>
<DataArray type="Int32" Name="ParticleID" NumberOfComponents="1"
format="ascii">
...
</DataArray>
... other arrays...
</PointData>
When I try to use this array as the "Id Channel Array" in the filter, however,
I get no output whatsoever from the filter. I think the rest of the file is
correct because the filter DOES generate pathlines when I leave the "Id Channel
Filter" to "Global or Local IDs", but the paths get messed up as soon as some
particles start leaving the domain (as they should, I guess).
What am I doing wrong? Do I need to define this 'ParticleID' array differently?
Thank you for your help,
Charles Boivin
