Class ParticleString3D

java.lang.Object

toxi.physics3d.ParticleString3D

public class ParticleString3D
extends Object

Utility builder/grouping/management class to connect a set of particles into a physical string/thread. Custom spring types can be used by subclassing this class and overwriting the createSpring(VerletParticle3D, VerletParticle3D, float, float) method.
