Detailed Description

This class handles all of the intersection processing for HAT/HOT and LOS requests.

It receives signals from the DtCigiConnection when these requests are received and tells the DtCigiDriver to generate responses. If running the CIGI driver in a separate thread, will use the driver's driver function queue to perform the operations.

virtual void makVrv::DtCigiIntersectionHandler::slot_onHatHotRequest	(	DtUniqueID	entityId,
		const DtVector &	localPosition,
		unsigned int	hotId,
		bool	hatRequested,
		unsigned int	lastHostFrameNumber
	)		[protected, virtual]

Slot called when signal_hatHotRequested is received from the CIGI connection.

Passes on the request to performHatHotRequest.

virtual void makVrv::DtCigiIntersectionHandler::performHatHotRequest	(	DtUniqueID	entityId,
		const DtVector &	localPosition,
		unsigned int	hotId,
		bool	hatRequested,
		unsigned int	lastHostFrameNumber
	)		[protected, virtual]

Performs the HAT/HOT calculation and calls generateHatHotResponse on the DtCigiDriver, which will (possibly) put it on the simulation function queue, telling the DtCigiConnection to queue up the response and send it the next time it sends CIGI messages.

Parameters:

entityId	The unique ID of the entity used in calculations. If this is 0, a database location is used in the calculation.
localPosition	The database location, or entity offset if the entityId is 0.
hotId	The HOT ID to respond with.
hatRequested	If true, calculates height above terrain. Calculates height of terrain if false.
lastHostFrameNumber	The last host frame received before the calculation takes place

virtual void makVrv::DtCigiIntersectionHandler::slot_onLineOfSightRequest	(	DtUniqueID	srcId,
		const DtVector &	srcLocation,
		DtUniqueID	dstId,
		const DtVector &	dstLocation,
		int	losId,
		int	hostFrame
	)		[protected, virtual]

Slot called when signal_losSegRequested is received from the CIGI connection.

Passes on the request to performLineOfSightRequest.

virtual void makVrv::DtCigiIntersectionHandler::performLineOfSightRequest	(	DtUniqueID	srcId,
		const DtVector &	srcLocation,
		DtUniqueID	dstId,
		const DtVector &	dstLocation,
		int	losId,
		int	hostFrame
	)		[protected, virtual]

Performs the line of sigh calculation and calls generateLosResponse on the DtCigiDriver, which will (possibly) put it on the simulation function queue, telling the DtCigiConnection to queue up the response and send it the next time it sends CIGI messages.

Parameters:

srcId	The unique ID of the source entity used in calculations. If this is 0, a database location is used in the calculation.
srcLocation	The database location of the source location, or entity offset if the srcId is 0.
dstId	The unique ID of the source entity used in calculations. If this is 0, a database location is used in the calculation.
dstLocation	The database location of the source location, or entity offset if the srcId is 0.
losId	The LOS ID to respond with.
hostFrame	The last host frame received before the calculation takes place

virtual void makVrv::DtCigiIntersectionHandler::setDatabaseCoordinateFromEntity	(	DtUniqueID	entity,
		const DtVector &	entityCoord,
		DtVector &	databaseCoord
	)		[protected, virtual]

Looks up the entity and uses the entity coordinates to calculate the database coordinate.

Parameters:

entity	The unique ID of the entity.
entityCoord	The entity coordinates (X out the front, Y out the right, Z down)
databaseCoord	Filled in with the database coordinate.

virtual double makVrv::DtCigiIntersectionHandler::groundHeight	(	const DtVector &	currentLocal,
		bool &	foundIntersection
	)		[protected, virtual]

Calculates the height of the terrain below currentLocal.

Parameters:

currentLocal	The point in database coordinates.
foundIntersection	Set to true if an intersection exists, false otherwise.

Returns:

The height of the terrain.
