## 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::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 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.

Placer& osgParticle::Placer::operator= | ( | const Placer & |  | ) | `[inline, protected]`

virtual void osgParticle::Placer::place | ( | Particle * | P | ) | const`[pure virtual]`

| Place a particle. Must be implemented in descendant classes. Implemented in osgParticle::MultiSegmentPlacer, osgParticle::PointPlacer, osgParticle::SectorPlacer, and osgParticle::SegmentPlacer.
