[LagrangianParticleTracker] Faster locator for vtkimage data

ParaView Support
1

Hey all,

I’d like to trace particles in an image-based velocity field (1000x500x500). Now everything works well but it is too slow to trace even 10k particles in such dataset. I found the following code may help to speed up the process.

https://gitlab.kitware.com/vtk/vtk/-/blob/2f1976cc6585643f62fc13ed42cbfd9b13b15c25/Filters/FlowPaths/vtkLagrangianBasicIntegrationModel.cxx#L1218

But how can I select such fast cartesian grid locator in Paraview?

Thanks,
Bin

You already are using it if you input data is a vtkImageData.
