Dispose particle emitter.
Should be called when destroying particle emitter.
Particle emitter state is automatically updated before rendering.
Reload internal material and geometry of this particle emitter.
Recretes the group and emitter object attached to the particle.
May be required after changing material related parameters.
Serialize object to JSON.
Update particle object matrix.
Ignores the particle position if the moveEmitter attribute is set true.
A dynamic particle emmiter ignores the position in its transform and applies it directly to the emitter origin.
