Member Function Documentation

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

Add the current mouse GUIEvent to internal stack.

bool gfx::TrackballManipulator::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* gfx::TrackballManipulator::className (   )  const [inline, virtual]

Definition at line 33 of file TrackballManipulator.

void gfx::TrackballManipulator::computePosition (  const osg::Vec3 &  eye, const osg::Vec3 &  lv, const osg::Vec3 &  up )

void gfx::TrackballManipulator::flushMouseEventStack (   )  [protected]

Reset the internal GUIEvent stack.

virtual osgUtil::SceneView::FusionDistanceMode gfx::TrackballManipulator::getFusionDistanceMode (   )  const [inline, virtual]

Get the FusionDistanceMode. Used by SceneView for setting up setereo convergence. Definition at line 48 of file TrackballManipulator.

virtual float gfx::TrackballManipulator::getFusionDistanceValue (   )  const [inline, virtual]

Get the FusionDistanceValue. Used by SceneView for setting up setereo convergence. Definition at line 51 of file TrackballManipulator. References _distance.

virtual osg::Matrixd gfx::TrackballManipulator::getInverseMatrix (   )  const [virtual]

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

virtual osg::Matrixd gfx::TrackballManipulator::getMatrix (   )  const [virtual]

get the position of the manipulator as 4x4 Matrix.

virtual osg::Node* gfx::TrackballManipulator::getNode (   )  [virtual]

Return node if attached.

virtual const osg::Node* gfx::TrackballManipulator::getNode (   )  const [virtual]

Return node if attached.

virtual void gfx::TrackballManipulator::getUsage (  osg::ApplicationUsage &  usage  )  const [virtual]

Get the keyboard and mouse usage of this manipulator.

virtual bool gfx::TrackballManipulator::handle (  const osgGA::GUIEventAdapter &  ea, osgGA::GUIActionAdapter &  us )  [virtual]

handle events, return true if handled, false otherwise.

virtual void gfx::TrackballManipulator::home (  const osgGA::GUIEventAdapter &  ea, osgGA::GUIActionAdapter &  us )  [virtual]

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

virtual void gfx::TrackballManipulator::init (  const osgGA::GUIEventAdapter &  ea, osgGA::GUIActionAdapter &  us )  [virtual]

Start/restart the manipulator.

bool gfx::TrackballManipulator::isMouseMoving (   )  [protected]

Check the speed at which the mouse is moving. If speed is below a threshold then return false, otherwise return true.

virtual void gfx::TrackballManipulator::setByInverseMatrix (  const osg::Matrixd &  matrix  )  [inline, virtual]

set the position of the matrix manipulator using a 4x4 Matrix. Definition at line 39 of file TrackballManipulator. References setByMatrix().

virtual void gfx::TrackballManipulator::setByMatrix (  const osg::Matrixd &  matrix  )  [virtual]

set the position of the matrix manipulator using a 4x4 Matrix. Referenced by setByInverseMatrix().

void gfx::TrackballManipulator::setModelScale (  float  scale  )  [inline]

Definition at line 69 of file TrackballManipulator. References _modelScale.

virtual void gfx::TrackballManipulator::setNode (  osg::Node *   )  [virtual]

Attach a node to the manipulator. Automatically detaches previously attached node. setNode(NULL) detaches previously nodes. Is ignored by manipulators which do not require a reference model.

float gfx::TrackballManipulator::tb_project_to_sphere (  float  r, float  x, float  y )  [protected]

void gfx::TrackballManipulator::trackball (  osg::Vec3 &  axis, float &  angle, float  p1x, float  p1y, float  p2x, float  p2y )  [protected]
