Detailed Description

Base class for motion commands that are generated by draggers.

Member Enumeration Documentation

Stage

enum osgManipulator::MotionCommand::Stage

Motion command are based on click-drag-release actions. So each command needs to indicate which stage of the motion the command represents.

Enumerator
NONE
START	Click or pick start.
MOVE	Drag or pick move.
FINISH	Release or pick finish.

References osgManipulator::DraggerCallback::receive().

createCommandInverse()

virtual MotionCommand * osgManipulator::MotionCommand::createCommandInverse ( )

pure virtual

create a MotionCommand that is the inverse of this command, and if applied will undo this commands changes.

Implemented in osgManipulator::Rotate3DCommand, osgManipulator::Scale1DCommand, osgManipulator::Scale2DCommand, osgManipulator::ScaleUniformCommand, osgManipulator::TranslateInLineCommand, and osgManipulator::TranslateInPlaneCommand.

References MotionCommand().

getLocalToWorld()

const osg::Matrix & osgManipulator::MotionCommand::getLocalToWorld ( ) const

inline

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

getMotionMatrix()

virtual osg::Matrix osgManipulator::MotionCommand::getMotionMatrix ( ) const

pure virtual

Gets the matrix for transforming the object being dragged. This matrix is in the command's coordinate systems.

Implemented in osgManipulator::Rotate3DCommand, osgManipulator::Scale1DCommand, osgManipulator::Scale2DCommand, osgManipulator::ScaleUniformCommand, osgManipulator::TranslateInLineCommand, and osgManipulator::TranslateInPlaneCommand.

getStage()

Stage osgManipulator::MotionCommand::getStage ( ) const

inline

getWorldToLocal()

const osg::Matrix & osgManipulator::MotionCommand::getWorldToLocal ( ) const

inline

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

setLocalToWorldAndWorldToLocal()

void osgManipulator::MotionCommand::setLocalToWorldAndWorldToLocal ( const osg::Matrix & localToWorld, const osg::Matrix & worldToLocal )

inline

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

setStage()

void osgManipulator::MotionCommand::setStage ( const Stage s )

inline
