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.

makVrv::DtCigiIntersectionHandler::DtCigiIntersectionHandler	(	DtDe &	de,

	)

Constructor.

virtual makVrv::DtCigiIntersectionHandler::~DtCigiIntersectionHandler ( )

virtual

Destructor.

Member Function Documentation

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

protectedvirtual

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
	)

protectedvirtual

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
	)

protectedvirtual

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
	)

protectedvirtual

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
	)

protectedvirtual

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
	)

protectedvirtual

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.

virtual void makVrv::DtCigiIntersectionHandler::generateLosResponse	(	int	losId,
		DtUniqueID	entityId,
		bool	visible,
		double	range,
		int	responseCount,
		int	hostFrame
	)

protectedvirtual

Generate a line-of-sight response.

Calls DtLosResponder::generateLosResponse directly if the driver is in a single thread or queue the response on myConnectionThreadFunctions queue if run in a separate thread.

Parameters

losId	The ID of the LOS response
entityId	The unique ID of the entity that was intersected
visible	Set to true if there were no intersection
range	Distance from the source before an intersection was hit.
responseCount	The number of intersections made with the request.
hostFrame	The last host frame when the calculation was made.

virtual void makVrv::DtCigiIntersectionHandler::generateHatHotResponse	(	double	height,
		unsigned int	hotId,
		bool	hat,
		unsigned int	lastFrame,
		bool	valid
	)

protectedvirtual

Generate a line-of-sight response.

Calls DtCigiConnection::sendHatHotResponse directly if the driver is in a single thread or queue the response on myConnectionThreadFunctions queue if run in a separate thread.

Parameters

height	The HAT/HOT
hotId	The ID of the HAT/HOT response
hat	HAT if true, HOT if false
lastFrame	The last host frame when the calculation was made.
valid	True if an intersection was made
