Detailed Description

An abstract base class for particle emitters. Descendant classes must override the emitParticles() method to generate new particles by calling the ParticleSystem::createParticle() method on the particle system associated to the emitter.

Member Function Documentation

virtual void osgParticle::Emitter::accept ( osg::NodeVisitor nv)
inlinevirtual

Visitor Pattern : calls the apply method of a NodeVisitor with this node's type.

Reimplemented from osgParticle::ParticleProcessor.

References osg::NodeVisitor::apply(), osg::NodeVisitor::popFromNodePath(), osg::NodeVisitor::pushOntoNodePath(), and osg::NodeVisitor::validNodeMask().

virtual const char* osgParticle::Emitter::className ( ) const
inlinevirtual

return the name of the node's class type.

Reimplemented from osgParticle::ParticleProcessor.

virtual void osgParticle::Emitter::emitParticles ( double  dt)
protectedpure virtual

Implemented in osgParticle::ModularEmitter.

Referenced by process().

const Particle & osgParticle::Emitter::getParticleTemplate ( ) const
inline

Get the particle template.

References _ptemp.

bool osgParticle::Emitter::getUseDefaultTemplate ( ) const
inline

Return whether the particle system's default template should be used.

References _usedeftemp.

virtual bool osgParticle::Emitter::isSameKindAs ( const osg::Object obj) const
inlinevirtual

return true if this and obj are of the same kind of object.

Reimplemented from osgParticle::ParticleProcessor.

virtual const char* osgParticle::Emitter::libraryName ( ) const
inlinevirtual

return the name of the node's library.

Reimplemented from osgParticle::ParticleProcessor.

Emitter& osgParticle::Emitter::operator= ( const Emitter )
inlineprotected
void osgParticle::Emitter::process ( double  dt)
inlineprotectedvirtual
void osgParticle::Emitter::setParticleTemplate ( const Particle p)
inline

Set the particle template (particle is copied).

References _ptemp, and _usedeftemp.

void osgParticle::Emitter::setUseDefaultTemplate ( bool  v)
inline

Set whether the default particle template should be used. When this flag is true, the particle template is ignored, and the particle system's default template is used instead.
