Often you'll need point distributions with non-overlapping points. Be it that you want to pack scales onto the surface of a fish or distribute vegetation on your procedural terrain. Although the "distribute points on faces" node comes with a poisson disc mode to remove overlapping points, that is not always the ideal solution. Relaxing the point positions through simulation can help in these situations. In this tutorial Manuel uses one of the experimental Geometry Nodes Simulation builds to implement a point relaxation simulation.
