Member Enumeration Documentation

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.

Member Function Documentation

void osgManipulator::MotionCommand::addSelection

(

Selection *

)

Add Selection (receiver) to the command.

The command will be executed on all the selections.

virtual void osgManipulator::MotionCommand::applyConstraint

(

const Constraint *

)

[pure virtual]

Apply a constraint to the command.

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

virtual bool osgManipulator::MotionCommand::execute

(

)

[pure virtual]

Execute the command.

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

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.

virtual osg::Matrix osgManipulator::MotionCommand::getMotionMatrix

(

)

const [pure virtual]

Gets the matrix for transforming the Selection.

This matrix is in the command's coordinate systems.

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

const SelectionList& osgManipulator::MotionCommand::getSelectionList

(

)

const [inline, protected]

SelectionList& osgManipulator::MotionCommand::getSelectionList

(

)

[inline, protected]

Stage osgManipulator::MotionCommand::getStage

(

)

const [inline]

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.

void osgManipulator::MotionCommand::removeSelection

(

Selection *

)

Remove Selection (receiver) from the command.

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.

void osgManipulator::MotionCommand::setStage

(

const Stage

s

)

[inline]

virtual bool osgManipulator::MotionCommand::unexecute

(

)

[pure virtual]

Undo the command.

The inverse of this command is executed.

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