Inheritance:

Public Methods

virtual const char* className() const

virtual void setByMatrix(const osg::Matrixd& matrix) = 0

set the position of the matrix manipulator using a 4x4 Matrix

virtual void setByInverseMatrix(const osg::Matrixd& matrix) = 0

set the position of the matrix manipulator using a 4x4 Matrix

virtual osg::Matrixd getMatrix() const = 0

get the position of the manipulator as 4x4 Matrix

virtual osg::Matrixd getInverseMatrix() const = 0

get the position of the manipulator as a inverse matrix of the manipulator, typically used as a model view matrix

virtual osgUtil::SceneView::FusionDistanceMode getFusionDistanceMode() const

Get the FusionDistanceMode.

virtual float getFusionDistanceValue() const

Get the FusionDistanceValue.

virtual void setNode(osg::Node*)

Attach a node to the manipulator, automatically detaching any previously attached node.

virtual const osg::Node* getNode() const

Return const node if attached

virtual osg::Node* getNode()

Return node if attached

virtual void home(const GUIEventAdapter&, GUIActionAdapter&)

Move the camera to the default position.

virtual void init(const GUIEventAdapter&, GUIActionAdapter&)

Start/restart the manipulator.

virtual bool handle(const GUIEventAdapter& ea, GUIActionAdapter& us)

Handle events, return true if handled, false otherwise.

virtual void accept(GUIEventHandlerVisitor& v)

Handle visitations

Documentation

MatrixManipulator is an abstract base class defining the interface, and a certain amount of default functionality, for classes which wish to control OSG cameras in response to GUI events.

virtual const char* className() const

virtual void setByMatrix(const osg::Matrixd& matrix) = 0

set the position of the matrix manipulator using a 4x4 Matrix

virtual void setByInverseMatrix(const osg::Matrixd& matrix) = 0

set the position of the matrix manipulator using a 4x4 Matrix

virtual osg::Matrixd getMatrix() const = 0

get the position of the manipulator as 4x4 Matrix

virtual osg::Matrixd getInverseMatrix() const = 0

get the position of the manipulator as a inverse matrix of the manipulator, typically used as a model view matrix

virtual osgUtil::SceneView::FusionDistanceMode getFusionDistanceMode() const

Get the FusionDistanceMode. Used by SceneView for setting up setereo convergence.

virtual float getFusionDistanceValue() const

Get the FusionDistanceValue. Used by SceneView for setting up setereo convergence.

virtual void setNode(osg::Node*)

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.

virtual const osg::Node* getNode() const

Return const node if attached

virtual osg::Node* getNode()

Return node if attached

virtual void home(const GUIEventAdapter&, GUIActionAdapter&)

Move the camera to the default position. May be ignored by manipulators if home functionality is not appropriate.

virtual void init(const GUIEventAdapter&, GUIActionAdapter&)

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

virtual bool handle(const GUIEventAdapter& ea, GUIActionAdapter& us)

Handle events, return true if handled, false otherwise.

virtual void accept(GUIEventHandlerVisitor& v)

Handle visitations
