All Superinterfaces:: X3DNode, X3DParticleEmitterNode

All Known Implementing Classes:: SurfaceEmitter

public interface SurfaceEmitter extends X3DParticleEmitterNode

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 interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
