Placer & | operator= (const Placer &) |
An abstract base class for implementing particle placers.
A placer is an object which take a particle as input, and places it somewhere by setting its position vector. Placer objects are used by the ModularEmitter
class as part of the particle emission process.

osgParticle::Placer::~Placer | ( | ) | [inline, protected] |
virtual const char* osgParticle::Placer::className | ( | ) | const [inline, virtual] |
return the name of the object's class type.
Must be defined by derived classes.
Implements osg::Object.
Reimplemented in osgParticle::CenteredPlacer.
virtual osg::Vec3 osgParticle::Placer::getControlPosition | ( | ) | const [pure virtual] |
Return the control position of particles that placer will generate. Must be implemented in descendant classes.
Implemented in osgParticle::BoxPlacer, osgParticle::MultiSegmentPlacer, osgParticle::SectorPlacer, osgParticle::SegmentPlacer, osgParticle::CompositePlacer, and osgParticle::PointPlacer.
virtual bool osgParticle::Placer::isSameKindAs | ( | const osg::Object * | obj | ) | const [inline, virtual] |
Reimplemented from osg::Object.
Reimplemented in osgParticle::CenteredPlacer.
virtual const char* osgParticle::Placer::libraryName | ( | ) | const [inline, virtual] |
return the name of the object's library.
Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.
Implements osg::Object.
Reimplemented in osgParticle::CenteredPlacer.
virtual void osgParticle::Placer::place | ( | Particle * | P | ) | const [pure virtual] |
Place a particle. Must be implemented in descendant classes.
Implemented in osgParticle::BoxPlacer, osgParticle::MultiSegmentPlacer, osgParticle::SectorPlacer, osgParticle::SegmentPlacer, osgParticle::CompositePlacer, and osgParticle::PointPlacer.
virtual float osgParticle::Placer::volume | ( | ) | const [inline, virtual] |
Volume of the placer. Can be implemented in descendant classes.
Reimplemented in osgParticle::BoxPlacer, osgParticle::MultiSegmentPlacer, osgParticle::SectorPlacer, osgParticle::SegmentPlacer, and osgParticle::CompositePlacer.
