public class SurfaceEmitter
extends X3DConcreteNode
implements SurfaceEmitter

SurfaceEmitter generates particles from the surface of an object.

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. SurfaceEmitter node tooltip: (X3D version 3.2 or later) [X3DParticleEmitterNode] SurfaceEmitter generates particles from the surface of an object. New particles are generated by first randomly choosing a face on the tessellated geometry and then a random position on that face. Particles are generated with an initial direction of the normal to that point (including any normal averaging due to normalPerVertex and creaseAngle field settings).

• Hint: ff surface is not solid (solid=false), randomly choose from which side of the surface to emit, negating the normal direction when generating from the back side.
• Warning: only valid geometry shall be used.

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.
