Interface SurfaceEmitter

All Superinterfaces:
X3DNode, X3DParticleEmitterNode
All Known Implementing Classes:
SurfaceEmitter
public interface SurfaceEmitter
extends X3DParticleEmitterNode
SurfaceEmitter generates particles from the surface of an object.

X3D 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).
