Class SphereConstraint

java.lang.Object

toxi.physics3d.constraints.SphereConstraint

All Implemented Interfaces:

ParticleConstraint3D

public class SphereConstraint
extends Object
implements ParticleConstraint3D

This class implements a spherical constraint for 3D VerletParticle3Ds. 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.

Constructor Details

SphereConstraint

public SphereConstraint(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(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 Details

apply

public void apply(VerletParticle3D p)

Description copied from interface: ParticleConstraint3D

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

Specified by:

apply in interface ParticleConstraint3D

Parameters:

p - particle
