Class NTreeForces

java.lang.Object

org.graphstream.boids.BoidForces

org.graphstream.boids.forces.ntree.NTreeForces

Direct Known Subclasses:

NTreeForces3D

public class NTreeForces
extends BoidForces

A basic definition of forces for a boid.

The kind of forces exercising on a boid can be changed to either use a n-tree or not, or to account for other kind of forces or another force model. This is the default force system that matches the basic boid definition as defined by Craig Reynolds.
