DtGimbalCompassOverlaySection extends DtOsgSensorViewCompassOverlaySection so that it can override its update() method. We need to do this because DtOsgSensorViewCompassOverlaySection makes an assumption about the way the observer is set up that is not valid in this case; it assumes that the observer is attached to the platform and then rotated to face the target (hence the observer's getAttachedRotation() can be used to get the orientation of the gimbal relative to the platform). However in this example, a gimbal object is created; oriented to point to the target each frame; and the observer is attached to that gimbal object. Therefore in this case the rotation of the observer relative to what it is attached to (the gimbal object) is always 0.

Member Function Documentation

virtual void DtGimbalCompassOverlaySection::update	(	const makVrv::DtOsgObserverObject &	,
		const makVrv::DtSensorFieldOfViewData &
	)

overridevirtual

This overrides the base update() method. It calls updateNorthIndicator(), updateEntityHeading() and updateAzimuthScale() with values provided by the DtGimbalSensorOverlay. It doesn't use the DtOsgObserverObject.

Reimplemented from makVrv::DtOsgSensorViewCompassOverlaySection.

virtual void DtGimbalCompassOverlaySection::setPlatformTopoOrientation ( double ori )

virtual

Set the topocentric orientation of the platform, in radians (0 to 2*PI)

virtual void DtGimbalCompassOverlaySection::setGimbalOrientation ( double ori )

virtual

Set the topocentric orientation of the gimbal, in radians (0 to 2*PI)
