Particle trajectory

hello

I want to know how to control the trajectory of a particles field in a 2d set system. For example following a square ,a circle or a triangle. How to apply a model of particle trajectory ?I need to understand it because I have complex shapes to map

thank you

hello, as i understand the particle field nodes from vux, the velocity field is a grid, at each grid point there is a vector that points into a direction. when a particle is near a grid point it goes into the direction of this point. so when you want the particles to go along a certain path, you have to form a vector field that leads the particles this way.

in the help patch you can see the velocity field, just play around with it. try to understand how the node works…

thank you tf

I’ll try to understand how it works
