public class ConeEmitter
extends X3DConcreteNode
implements ConeEmitter

ConeEmitter generates all available particles from a specific point in space.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. ConeEmitter node tooltip: (X3D version 3.2 or later) [X3DParticleEmitterNode] ConeEmitter generates all available particles from a specific point in space. Particles are emitted from the single point specified by the position field emanating in a direction randomly distributed within the cone specified by the angle and direction fields. *


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.
