3D Boids is a curious simulator that`s especially created for all those who like ornithology. It simulates the behaviour of birds while they fly, both solo or in flocks.
3D Boids shows you the distinct and intelligent shapes that the birds create, and how the number of them influences the shapes and patterns of flight. The simulator also studies the cohesion (how they all interact while flying), the way they align depending on the speed of the flock, the designation of the leader, the random behaviours, etc.
3D Boids is a completely free simulator.
