All Implemented Interfaces:: X3DNode, PointEmitter, X3DParticleEmitterNode

public class PointEmitterObject
extends X3DConcreteNode
implements PointEmitter

PointEmitter generates particles from a specific point in space using the specified direction and speed.

X3D node tooltip: (X3D version 3.2 or later) [X3DParticleEmitterNode] PointEmitter generates particles from a specific point in space using the specified direction and speed. *

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
