ModularProgram to perform operations on particles before they are updated.
To implement a new operator, derive from this class and override the operate() method. You should also override the beginOperate() method to query the calling program for the reference frame used, and initialize the right transformations if needed.

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.

return the name of the object's class type.
Must be defined by derived classes.
Implements osg::Object.

Reimplemented from osg::Object.

Do something on a particle.
This method is called by ModularProgram objects to perform some operations on the particles. You must override it in descendant classes. Common operations consist of modifying the particle's velocity vector. The dt parameter is the time elapsed from last operation.
Implemented in osgParticle::AccelOperator, osgParticle::AngularAccelOperator, osgParticle::FluidFrictionOperator, and osgParticle::ForceOperator.
| virtual void osgParticle::Operator::beginOperate | ( | Program * | ) | [inline, virtual] |
Do something before processing particles via the operate() method.
Overriding this method could be necessary to query the calling Program object for the current reference frame. If the reference frame is RELATIVE_RF, then your class should prepare itself to do all operations in local coordinates.
Reimplemented in osgParticle::AccelOperator, osgParticle::AngularAccelOperator, osgParticle::FluidFrictionOperator, and osgParticle::ForceOperator.
| virtual void osgParticle::Operator::endOperate | ( | ) | [inline, virtual] |
Do something after all particles have been processed.
