public class ShapeParticleSystem
extends javax.media.j3d.Group
implements ParticleSystemInterface, ParticleLifeCycleListener

A particle system that uses any Shape3D as a particle. This particle system uses the user data of each Shape3D particle to maintain scene graph information. The collision bounds of the shape is assigned by the shape factory based on the radius of the particle. The collision bounds is a BoundingBox.
