Class SphereConstraint

java.lang.Object
  toxi.physics.constraints.SphereConstraint

All Implemented Interfaces:

ParticleConstraint

public class SphereConstraint
extends java.lang.Object
implements ParticleConstraint

This class implements a spherical constraint for 3D VerletParticles. The constraint can be configured in two ways: A bounding sphere not allowing particles to escape or alternatively does not allow particles to enter the space occupied by the sphere.

Field Summary

static boolean	INSIDE
boolean	isBoundingSphere
static boolean	OUTSIDE
toxi.geom.Sphere	sphere

Constructor Summary

SphereConstraint(toxi.geom.Sphere sphere, boolean isBoundary)
Creates a new instance using the sphere definition and constraint mode given.

SphereConstraint(toxi.geom.Vec3D origin, float radius, boolean isBoundary)
Creates a new instance using the sphere definition and constraint mode given.

Method Summary

void	apply(VerletParticle p) Applies the constraint to the passed in particle.

Constructor Detail

SphereConstraint

public SphereConstraint(toxi.geom.Sphere sphere,
                        boolean isBoundary)

Creates a new instance using the sphere definition and constraint mode given.

Parameters:

sphere - sphere instance

isBoundary - constraint mode. Use INSIDE or OUTSIDE to specify constraint behaviour.

SphereConstraint

public SphereConstraint(toxi.geom.Vec3D origin,
                        float radius,
                        boolean isBoundary)

Creates a new instance using the sphere definition and constraint mode given.

Parameters:

origin - sphere origin

radius - sphere radius

isBoundary - constraint mode. Use INSIDE or OUTSIDE to specify constraint behaviour.

Method Detail

apply

public void apply(VerletParticle p)

Description copied from interface: ParticleConstraint

Applies the constraint to the passed in particle. The method is assumed to manipulate the given instance directly.

Specified by:

apply in interface ParticleConstraint

Parameters:

p - particle
