DtSimpleIntersector is a higher-level intersector class which adds functions for line of sight, height above terrain and height over terrain. This also enables the user to find out the type of element intersected with (terrain patch, entity, prop, etc)

Member Function Documentation

static DtSimpleIntersector& makVrv::DtSimpleIntersector::instance ( DtDe & de )

static

Get the instance of the DtSimpleIntersector.

static void makVrv::DtSimpleIntersector::registerInstance	(	DtDe &	de,
		DtSimpleIntersector *	anInstance
	)

static

Register the instance with the DtDe.

virtual double makVrv::DtSimpleIntersector::heightAboveTerrain	(	const DtVector &	loc,
		DtSimpleIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`,
		bool	includeEntities = `false`,
		std::vector< DtElementID > *	ignoreList = `0`
	)

virtual

Returns the height above the terrain at location loc. The position of the terrain is returned in terrainLoc.

virtual double makVrv::DtSimpleIntersector::heightAboveTerrain	(	DtElementID	element,
		DtSimpleIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`,
		bool	includeEntities = `false`,
		std::vector< DtElementID > *	ignoreList = `0`
	)

virtual

virtual double makVrv::DtSimpleIntersector::heightOfTerrain	(	const DtVector &	loc,
		DtSimpleIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`
	)

virtual

Returns the height of the terrain at the given location using local coordinates. It will return the altutide in geodetic coordinates. Hit location defaults to the supplied location if no intersection occurred.

virtual bool makVrv::DtSimpleIntersector::hasLineOfSight	(	const DtVector &	fromLoc,
		const DtVector &	toLoc,
		DtSimpleIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`,
		bool	includeEntities = `false`,
		std::vector< DtElementID > *	ignoreList = `0`
	)

virtual

Returns true if there is nothing blocking line of sight between the two points. If false is returned, the location of the intersection will be stored in hitLoc.

virtual bool makVrv::DtSimpleIntersector::hasLineOfSight	(	DtElementID	fromElem,
		DtElementID	toElem,
		DtSimpleIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`,

	)

virtual

virtual DtUniqueID makVrv::DtSimpleIntersector::sceneObjectIdFromElementId	(	DtElementID	element,
		DtModelSetId	modelSet
	)

protectedvirtual

Gets the scene object ID from the element ID.

virtual DtVector makVrv::DtSimpleIntersector::positionFromSceneObjectId ( DtUniqueID sceneObjectId )

protectedvirtual

Gets the position of the scene object.

virtual bool makVrv::DtSimpleIntersector::getTerrainIntersection	(	const DtVector &	loc,
		DtIntersectorResult &	result,
		DtModelSetId	modelSet = `DtModelSetId::Models3D`,
		bool	useHighLod = `false`,
		bool	includeEntities = `false`,
		std::vector< DtElementID > *	ignoreList = `0`
	)

protectedvirtual

Returns true if there is an intersection, putting the intersection result in result.

virtual void makVrv::DtSimpleIntersector::fillInElementType ( DtSimpleIntersectorResult & result )

protectedvirtual

virtual void makVrv::DtSimpleIntersector::slot_coordinateSystemChanged ( )

protectedvirtual

slot for when the coordinate system changes
