Particle Tracking

We are trying to visualize pathlines using particle tracking (vtkParticleTracer) with an unstructured grid
there is one example TestParticleTracers, which works on a regular grid.
We used the sample example adapting it so it uses an unstructured grid.
on request and execute it seems that it does not find “vectors”.
I guess we are doing something wrong.
is there any more detailed documentation on this ?

Hi there, did you ever get vtkParticleTracer to work? I’m also having a hard time getting it to work on unstructured data. Thanks!

vtkParticleTracer can be tricky to use.

You need to make sure your data is distributed.
