Public Member Functions
	Projector ()
virtual bool	project (const PointerInfo &pi, osg::Vec3d &projectedPoint) const =0
	Calculates the object/world coordinates (projectedPoint) of a window coordinate (pointToProject) when projected onto some shape or geometry (implemented in derived classes).
void	setLocalToWorld (const osg::Matrix &localToWorld)
	Sets the matrix for transforming the projector's local coordinate system to the world/object coordinate system.
const osg::Matrix &	getLocalToWorld () const
	Gets the matrix for transforming the projector's local coordinate system to the world/object coordinate system.
const osg::Matrix &	getWorldToLocal () const
	Gets the matrix for transforming the world/object coordinate system to the command's local coordinate system.
Public Member Functions inherited from osg::Referenced
	Referenced ()
	Referenced (bool threadSafeRefUnref)
	Deprecated, Referenced is now always uses thread safe ref/unref, use default Referenced() constructor instead.
	Referenced (const Referenced &)
Referenced &	operator= (const Referenced &)
virtual void	setThreadSafeRefUnref (bool)
	Deprecated, Referenced is always theadsafe so there method now has no effect and does not need to be called.
bool	getThreadSafeRefUnref () const
	Get whether a mutex is used to ensure ref() and unref() are thread safe.
OpenThreads::Mutex *	getRefMutex () const
	Get the mutex used to ensure thread safety of ref()/unref().
int	ref () const
	Increment the reference count by one, indicating that this object has another pointer which is referencing it.
int	unref () const
	Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
int	unref_nodelete () const
	Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
int	referenceCount () const
	Return the number of pointers currently referencing this object.
ObserverSet *	getObserverSet () const
	Get the ObserverSet if one is attached, otherwise return NULL.
ObserverSet *	getOrCreateObserverSet () const
	Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet.
void	addObserver (Observer *observer) const
	Add a Observer that is observing this object, notify the Observer when this object gets deleted.
void	removeObserver (Observer *observer) const
	Remove Observer that is observing this object.

inline

Gets the matrix for transforming the projector's local coordinate system to the world/object coordinate system.

References _localToWorld.

getWorldToLocal()

const osg::Matrix & osgManipulator::Projector::getWorldToLocal ( ) const

project()

virtual bool osgManipulator::Projector::project ( const PointerInfo & pi, osg::Vec3d & projectedPoint ) const

pure virtual

Calculates the object/world coordinates (projectedPoint) of a window coordinate (pointToProject) when projected onto some shape or geometry (implemented in derived classes).

SceneView in used for i projecting window coordinates into object coordinates and vice versa. Returns true on successful projection.

Implemented in osgManipulator::CylinderPlaneProjector, osgManipulator::CylinderProjector, osgManipulator::LineProjector, osgManipulator::PlaneProjector, osgManipulator::SpherePlaneProjector, and osgManipulator::SphereProjector.

setLocalToWorld()

void osgManipulator::Projector::setLocalToWorld ( const osg::Matrix & localToWorld )

inline

Sets the matrix for transforming the projector's local coordinate system to the world/object coordinate system.

References _localToWorld, and _worldToLocalDirty.
