[LagrangianParticleTracker] Faster locator for vtkimage data

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.


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


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