Member Function Documentation

virtual void makVrv::DtDeadReckonUpdater::update ( DtTime tNow )

virtual

call updateSpacial()

Reimplemented from makVrv::DtSceneObjectUpdater.

virtual void makVrv::DtDeadReckonUpdater::setSceneObject ( DtSceneObject * sceneObject )

virtual

sets the scene object to update via the id.

This override called the base implementation as well as ensuring the current motion model is updating the current models on the scene object.

Reimplemented from makVrv::DtSceneObjectUpdater.

virtual void makVrv::DtDeadReckonUpdater::setVelocity ( const DtVector32 & velocity )

virtual

Set the object's velocity.

virtual void makVrv::DtDeadReckonUpdater::setVelocity	(	const DtVector32 &	velocity,
		double	time
	)

virtual

virtual void makVrv::DtDeadReckonUpdater::setAcceleration ( const DtVector32 & acceleration )

virtual

Set the object's velocity.

virtual void makVrv::DtDeadReckonUpdater::setAcceleration	(	const DtVector32 &	acceleration,
		double	time
	)

virtual

virtual void makVrv::DtDeadReckonUpdater::setAngularVelocity ( const DtVector32 & angularVelocity )

virtual

Set the object's rotational velocity.

virtual void makVrv::DtDeadReckonUpdater::setAngularVelocity	(	const DtVector32 &	angularVelocity,
		double	time
	)

virtual

virtual void makVrv::DtDeadReckonUpdater::setInputPosition ( const DtVector & position )

virtual

Set the object's position with a time for absolute timestamping.

Reimplemented from makVrv::DtSceneObjectUpdater.

virtual void makVrv::DtDeadReckonUpdater::setInputPosition	(	const DtVector &	position,
		double	time
	)

virtual

virtual void makVrv::DtDeadReckonUpdater::setInputOrientation ( const DtTaitBryan & ori )

virtual

Set the object's orientation with a time specified for absolute time stampint.

Reimplemented from makVrv::DtSceneObjectUpdater.

virtual void makVrv::DtDeadReckonUpdater::setInputOrientation	(	const DtTaitBryan &	ori,
		double	time
	)

virtual

virtual void makVrv::DtDeadReckonUpdater::setDeadReckoningSettings	(	bool	deadReckonPosition,
		bool	deadReckonVelocity,
		bool	deadReckonOrientation
	)

virtual

Set the object's dead reckoning settings.

virtual void makVrv::DtDeadReckonUpdater::setSmoothingEnabled ( bool enabled )

virtual

Turn the smoother on or off.

virtual void makVrv::DtDeadReckonUpdater::setSmoothingPeriod ( float period )

virtual

Set the period for the smoother.

virtual void makVrv::DtDeadReckonUpdater::resetSmoother ( )

virtual

Reset the smoother. Used when changing from embarked to disembarked and vice versa.

virtual void makVrv::DtDeadReckonUpdater::updateSpacial ( DtTime tNow )

virtual

Update the spacial attributes using the given simulation time.

void makVrv::DtDeadReckonUpdater::setMotionModel ( const std::string & modelName )

Set which motion model the object should use.

DtMotionModel* makVrv::DtDeadReckonUpdater::motionModel ( ) const

Get the motion model.

virtual void makVrv::DtDeadReckonUpdater::setUseAbsoluteTimeStamping ( bool )

virtual

Sets whether or not to use absolute time stamping (default is false).

If true, when the update method is called the de's systemClock() will be used rather than the supplied simulation time

bool makVrv::DtDeadReckonUpdater::useAbsoluteTimeStamping ( ) const

virtual void makVrv::DtDeadReckonUpdater::setFrozen ( bool frozen )

virtual

Suspend / resume dead reckoning.

virtual bool makVrv::DtDeadReckonUpdater::isFrozen ( ) const

virtual

virtual const DtVector& makVrv::DtDeadReckonUpdater::approxLocation ( DtTime curTime ) const

virtual

Because of time stamping, use these routines to get values from the motion model.

Do not go to the motion model itself Get the approximated (i.e. dead-reckoned for base DtDeadReckoner) location at the specified time.

virtual const DtVector32& makVrv::DtDeadReckonUpdater::approxVelocity ( DtTime curTime ) const

virtual

Get the approximated (i.e.

dead-reckoned for base DtDeadReckoner) velocity at the specified time. Note that the 'smoothed' velocity is a misnomer - this velocity has really been potentially 'de-smoothed' to provide a smoothed location when used to do smoothing

virtual const DtVector32& makVrv::DtDeadReckonUpdater::approxUnsmoothedVelocity ( DtTime curTime ) const

virtual

Get the unsmoothed approximated (i.e.

dead-reckoned for base DtDeadReckoner) velocity at the specified time.

virtual

Get the approximated (i.e.

dead-reckoned for base DtDeadReckoner) orientation at the specified time.

virtual

Get the acceleration for the specified time.

virtual const DtVector32& makVrv::DtDeadReckonUpdater::rotationalVelocity ( DtTime curTime ) const

virtual

Get the rotation velocity for the specified time.
