Detailed Description

A useful node class for updating particle systems automatically.

When a ParticleSystemUpdater is traversed by a cull visitor, it calls the update() method on the specified particle systems. You should place this updater AFTER other nodes like emitters and programs.

)

const [inline]

return true if ParticleSystem is contained within ParticlsSystemUpdater.

unsigned int osgParticle::ParticleSystemUpdater::getParticleSystemIndex

(

const ParticleSystem *

ps

)

const [inline]

get index number of ParticleSystem.

virtual void osgParticle::ParticleSystemUpdater::traverse

(

osg::NodeVisitor &

)

[virtual]

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Node.

virtual osg::BoundingSphere osgParticle::ParticleSystemUpdater::computeBound

(

)

const [virtual]

Compute the bounding sphere around Node's geometry or children.

This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound().

Reimplemented from osg::Node.
