Hello everybody. I want to visualize particles and their pathlines in Paraview. Everything works so far with the Table to Points filter and then the Temporal Particles to Pathlines Filter. However, I am missing a feature that lets me determine the tracklength. I would like to “layer” multiple timesteps above each other while animating it in time. Just like the “Group time steps” filter does, but not statically (only for a predefined interval) but dynamically (defining the interval length and being able to animate through the whole time series).

Is anyone aware of such a feature or knows a workaround to this problem? I would be super grateful!
