Documentation

An abstract ParticleProcessor descendant for modifying particles "on the fly" during the cull traversal. Descendants of this class must implement the execute() method, which should iterate through all particles in the linked particle system and modify them somehow (usually updating their velocity vector).

Program()

Program(const Program &copy, const osg::CopyOp &copyop = osg::CopyOp::SHALLOW_COPY)

virtual const char* libraryName() const

virtual const char* className() const

virtual bool isSameKindAs(const osg::Object* obj) const

virtual void accept(osg::NodeVisitor& nv)

virtual ~Program()

Program& operator=(const Program &)

virtual void execute(double dt) = 0

Execute the program on the particle system. Must be overriden in descendant classes.

inline void process(double dt)

Implementation of ParticleProcessor::process(). Do not call this method by yourself.
