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::SpherePlaneProjector, osgManipulator::SphereProjector, osgManipulator::PlaneProjector, and osgManipulator::LineProjector.
