Member Function Documentation

virtual void osgManipulator::Scale2DCommand::applyConstraint ( const Constraint ) [virtual]

Apply a constraint to the command.

Implements osgManipulator::MotionCommand.

virtual bool osgManipulator::Scale2DCommand::execute ( ) [virtual]

Execute the command.

Implements osgManipulator::MotionCommand.

const osg::Vec2d& osgManipulator::Scale2DCommand::getMinScale ( ) const [inline]
virtual osg::Matrix osgManipulator::Scale2DCommand::getMotionMatrix ( ) const [inline, virtual]

Gets the matrix for transforming the Selection.

This matrix is in the command's coordinate systems.

Implements osgManipulator::MotionCommand.
