Detailed Description

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,
		int	modelSet = 0,
		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,
		int	modelSet = 0,
		bool	useHighLod = false,
		bool	includeEntities = false,
		std::vector< DtElementID > *	ignoreList = 0
	)		[virtual]

virtual double makVrv::DtSimpleIntersector::heightOfTerrain	(	const DtVector &	loc,
		DtSimpleIntersectorResult &	result,
		int	modelSet = 0,
		bool	useHighLod = false
	)		[virtual]

Returns the height of the terrain at the given location.

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

virtual DtUniqueID makVrv::DtSimpleIntersector::sceneObjectIdFromElementId	(	DtElementID	element,
		int	modelSet
	)		[protected, virtual]

Gets the scene object ID from the element ID.

virtual DtVector makVrv::DtSimpleIntersector::positionFromSceneObjectId

(

DtUniqueID

sceneObjectId

)

[protected, virtual]

Gets the position of the scene object.

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

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