Documentation

An abstract base class used by 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.

virtual const char* libraryName() const

virtual const char* className() const

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

virtual void operate(Particle* P, double dt) = 0

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.

virtual void beginOperate(Program* )

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_TO_PARENTS, then your class should prepare itself to do all operations in local coordinates.

virtual void endOperate()

Do something after all particles have been processed

virtual ~Operator()

Operator& operator=(const Operator &)

inline Operator()

inline Operator(const Operator &copy, const osg::CopyOp &copyop)

inline bool isEnabled() const

Get whether this operator is enabled

inline void setEnabled(bool v)

Enable or disable this operator
