This class handles all of the intersection processing for HAT/HOT, LOS , and Collision segment 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 ( const DtHatHotResponder::DtHatHotRequestData & request )

protectedvirtual

Slot called when signal_hatHotRequested is received from the CIGI connection. Passes on the request to performHatHotRequest.

virtual void makVrv::DtCigiIntersectionHandler::performHatHotRequest ( const DtHatHotResponder::DtHatHotRequestData & request )

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.

virtual void makVrv::DtCigiIntersectionHandler::slot_lineOfSightCheckRequest	(	DtCigiLosRequest *	request,
		bool	takeOwnership
	)

protectedvirtual

Slot called when signal_losSegRequested is received from the CIGI connection. Passes on the request to performLineOfSightRequest.

virtual void makVrv::DtCigiIntersectionHandler::performLineOfSightRequest	(	DtCigiLosRequest *	request,
		bool	takeOwnership
	)

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::slot_onCollisionSegmentCheckRequest ( DtCollisionResponder::DtCollisionSegmentDefinitionData * request )

protectedvirtual

Slot called when signal_collisionSegmentCheckRequest is called from collision handler. Passes request to performCollisionSegmentRequest. Will queue performCollisionSegmentRequest up for the render thread if using thread.

virtual void makVrv::DtCigiIntersectionHandler::performCollisionSegmentRequest ( DtCollisionResponder::DtCollisionSegmentDefinitionData * request )

protectedvirtual

Performs intersection request with a line segment and generates collision segment responses based on intersections Called from performCollisionSegmentRequest, and calls generateCollisionSegmentResponse This method runs in the render thread if DtCigiConnection is running in a thread.

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 void makVrv::DtCigiIntersectionHandler::setEntityCoordinateFromDatabase	(	DtUniqueID	entity,
		const DtVector &	databaseCoord,
		DtVector &	entityCoord
	)

protectedvirtual

Looks up the entity and uses the entity's position and orientation to transformn the database coordinate into the entity's coordinate system.

Parameters

entity	The unique ID of the entity.
databaseCoord	The coordinate to transform
entityCoord	The result in entity coordinates

virtual void makVrv::DtCigiIntersectionHandler::setGeodeticCoordinateFromDatabase	(	const DtVector &	from,
		DtGeodeticCoord &	to
	)

protectedvirtual

Utility function sets a geodetic coordinate from a database coordinate.

virtual void makVrv::DtCigiIntersectionHandler::getNormalAzAndEl	(	const DtVector &	databaseCoord,
		const DtVector &	normal,
		float &	normalAz,
		float &	normalEl
	)

protectedvirtual

Get the azimuth and elevation of the supplied normal wrt north and up. If the database is geocentric, create a topo system at the location of the databaseCoord; otherwise it can be ignored, as the normal is already wrt north and up.
