This geometry nodes setup provides presets for generating and simulating Brownian motion in Blender. Users can create single or multiple random paths, with or without spatial confinement. The presets allow particles to follow generated paths while independently maintaining rotation.

The system includes simulation capabilities for animating multiple particles within a confined space. The physics calculation treats collisions exclusively against the main collision object rather than computing complex inter-particle collisions. To prevent intersections, the node setup includes a function to relax positions and push apart overlapping particles.
