Member Function Documentation

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.

Definition at line 59 of file Projector.h.

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.

Here is the call graph for this function:

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.

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.
