Detailed Description

FlightManipulator is a MatrixManipulator which provides flight simulator-like updating of the camera position & orientation. By default, the left mouse button accelerates, the right mouse button decelerates, and the middle mouse button (or left and right simultaneously) stops dead.

Member Function Documentation

void osgGA::FlightManipulator::addMouseEvent ( const GUIEventAdapter & ea ) [protected]

Add the current mouse GUIEvent to internal stack.

bool osgGA::FlightManipulator::calcMovement ( ) [protected]

For the give mouse movement calculate the movement of the camera. Return true is camera has moved and a redraw is required.

virtual const char* osgGA::FlightManipulator::className ( ) const [inline, virtual]

return the name of the object's class type. Must be defined by derived classes.
Reimplemented from osgGA::MatrixManipulator.

void osgGA::FlightManipulator::computePosition ( const osg::Vec3 & eye,

const osg::Vec3 & lv,

const osg::Vec3 & up

) [protected]

void osgGA::FlightManipulator::flushMouseEventStack ( ) [protected]

Reset the internal GUIEvent stack.

virtual osg::Matrixd osgGA::FlightManipulator::getInverseMatrix ( ) const [virtual]

get the position of the manipulator as a inverse matrix of the manipulator, typically used as a model view matrix.
Implements osgGA::MatrixManipulator.

virtual osg::Matrixd osgGA::FlightManipulator::getMatrix ( ) const [virtual]

get the position of the manipulator as 4x4 Matrix.
Implements osgGA::MatrixManipulator.

virtual osg::Node* osgGA::FlightManipulator::getNode ( ) [virtual]

Return node if attached.
Reimplemented from osgGA::MatrixManipulator.

virtual const osg::Node* osgGA::FlightManipulator::getNode ( ) const [virtual]

Return const node if attached.
Reimplemented from osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::getUsage ( osg::ApplicationUsage & usage ) const [virtual]

Get the keyboard and mouse usage of this manipulator.
Reimplemented from osgGA::GUIEventHandler.

virtual bool osgGA::FlightManipulator::handle ( const GUIEventAdapter & ea,

GUIActionAdapter & us

) [virtual]

Handle events, return true if handled, false otherwise.
Reimplemented from osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::home ( const GUIEventAdapter & ea,

GUIActionAdapter & us

) [virtual]

Move the camera to the default position. May be ignored by manipulators if home functionality is not appropriate.
Reimplemented from osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::init ( const GUIEventAdapter & ea,

GUIActionAdapter & us

) [virtual]

Start/restart the manipulator. FIXME: what does this actually mean? Provide examples.
Reimplemented from osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::setByInverseMatrix ( const osg::Matrixd & matrix ) [inline, virtual]

set the position of the matrix manipulator using a 4x4 Matrix.
Implements osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::setByMatrix ( const osg::Matrixd & matrix ) [virtual]

set the position of the matrix manipulator using a 4x4 Matrix.
Implements osgGA::MatrixManipulator.

virtual void osgGA::FlightManipulator::setNode ( osg::Node * ) [virtual]

Attach a node to the manipulator, automatically detaching any previously attached node. setNode(NULL) detaches previous nodes. May be ignored by manipulators which do not require a reference model.
Reimplemented from osgGA::MatrixManipulator.
