Detailed Description

Base class for Projectors. Projectors maps 2D cursor motions to 3D motions.

Member Function Documentation

§ getLocalToWorld()

const osg::Matrix& osgManipulator::Projector::getLocalToWorld ( ) const
inline

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

§ getWorldToLocal()

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

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

§ 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.
