Detailed Description

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.

Member Function Documentation

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 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 bool osgParticle::Placer::isSameKindAs ( const osg::Object obj  )  const [inline, virtual]

Reimplemented from 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::PointPlacer, osgParticle::SectorPlacer, and osgParticle::SegmentPlacer.

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::PointPlacer, osgParticle::SectorPlacer, and osgParticle::SegmentPlacer.
