How to Simulate a 100.000+ Fish Swarm in Blender!

In this video, we will procedurally generate a fish swarm with thousands of fish using Simulation Nodes in Blender 4.0. The fish school is very interactive in that you have complete control over the movements and the rotations of the fish. We will even make the Geometry Nodes system to make the fish avoid objects just like in real life! All of this is done by using specific mathematical equations to, for example, calculate the angle from point to centre, the new position of a point over time, and a real-time updating velocity vector.
