virtual Standard_Boolean	IsDirty () const
	Returns TRUE if object state should be updated.

virtual void	MarkDirty ()
	Marks object state as outdated (needs BVH rebuilding).

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
