How to describe the motion trajectory of a particle

Hello researchers, I have two VTK files containing particle information, which includes two types of particles. I want to track the motion trajectory of a particle with type = 1 and obtain the results shown in the following figure. What should I do?

Hi @Guanlong

Your archive contains two files, which are two separate 2D point clouds.
Point do have a type property and you can extract the point for type==1 if you want.

However, there is no timesteps inside to create a particle path with.

Thank you for your reply. I want to upload multiple VTK files, but the website has a file size limit, so I can only upload two files. Is there any other way to upload files? I don’t know how to obtain the trajectory of particles.
