Complex 3D Paths

Hi everyone.
How to create complex 3D paths along which particles can flow in Fusion?
Looks like:

Just animate the emitter position and create a path. What part of this do you need assistance with?
Your example doesn't look that complex. It's just a x/z circle that goes round and round while moving up in the y direction.

Thank you very much for your reply.
