Boids is an artificial life program, developed by Craig Reynolds inwhich simulates the flocking behaviour of birds. As with most artificial life simulations, Boids is an example of emergent behavior; that is, the complexity of Boids arises from the interaction of individual agents the boids, in this case adhering to a set of simple rules.
The rules applied in the simplest Boids world are as follows:. The basic model has been extended in several different ways since Reynolds proposed it.
Boids Flocking Model
Olfaction was used to transmit emotion between animals, through pheromones modelled as particles in a free expansion gas. Hartman and Benes  introduced a complementary force to the alignment that they call the change of leadership. This steer defines the reynlods of the boid to become a leader and try to escape. The movement of Boids can be characterized as either chaotic splitting groups and wild behaviour or orderly.
Unexpected behaviours, such as splitting flocks and reuniting after avoiding obstacles, can be considered emergent. The boids framework is often used in computer graphics, providing realistic-looking representations of flocks of birds and other creatures, such as schools of fish or herds of animals.
It was for instance used in the video game Half-Life for the flying bird-like creatures seen at the end of the game on Xennamed “boid” in the game files.
Boids: An Implementation of Craig W. Reynolds’ Flocking Model
At the time of proposal, Reynolds’ approach represented a giant step forward compared to the traditional techniques used in computer animation for motion pictures.
The first animation created with the model was Stanley and Stella in: Breaking the Icefollowed by a feature film debut in Tim Burton ‘s film Batman Returns with computer generated bat swarms and armies of penguins marching through the streets of Gotham City.
The boids model has been used for other interesting applications.
It has been applied to automatically program Internet multi-channel radio stations. From Wikipedia, the free encyclopedia.
