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

§ 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.
