Particle system with 2D vector field For Beginners & Intermediate

Hi!

The idea behind this tutorial is somewhat similar to my older particles on 3D SDF, but instead of mathematically describing 3D geometry with sign distance function, here we using difference in brightness of 2D texture to calculate particle velocities.

Driving particles with vector fields is one of the most common practice in generative art, I'm sure you've seen particle trails made this way. So, here is tutorial for making those in Touch.

You can download main example from attached file or support me on Patreon and get additional example as well
