virtual bool DtEllipsoidTerrainImplementation::loadTerrain	(	const makArchives::DtGenericTerrainRecord &	rec,
		const TerrainSettings &	settings = TerrainSettings()
	)		[virtual]

Loads a terrain given the terrain record and a key/value pair of settings.

These settings are interpreted (or not) by the implementation

Implements DtTerrainImplementation.

virtual const Coordinate_System* DtEllipsoidTerrainImplementation::coordinateSystem

(

)

const [virtual]

Implements DtTerrainImplementation.

virtual bool DtEllipsoidTerrainImplementation::chordIntersect	(	const DtChord &	chord,
		DtChordIntersectionRecord &	record,
		DtIntersectionRecord::DtIntersectionType	irtFlag = DtIntersectionRecord::INT_ALL_DATA,
		bool *	dataAvailable = 0,
		bool	overrideBlockingAssert = false
	)		const [virtual]

Returns topmost intersection of chord with terrain in record.

irtFlag specifies what intersection data should be filled in for the record.

Implements DtTerrainImplementation.

virtual bool DtEllipsoidTerrainImplementation::allIntersectsAlongChord	(	const DtChord &	chord,
		DtChordIntersectRecordList &	intList,
		DtIntersectionRecord::DtIntersectionType	irtFlag = DtIntersectionRecord::INT_ALL_DATA,
		bool *	dataAvailable = 0,
		bool	overrideBlockingAssert = false
	)		const [virtual]

Returns all intersections of chord with terrain.

intList is the list of each intersection record. irtFlag specifies what intersection data should be filled in for the record.

Implements DtTerrainImplementation.

virtual bool DtEllipsoidTerrainImplementation::sphereIntersect	(	const DtSphere &	sphere,
		DtSphereIntersectionRecord &	record,
		DtIntersectionRecord::DtIntersectionType	irtFlag = DtIntersectionRecord::INT_ALL_DATA,
		bool *	dataAvailable = 0,
		bool	overrideBlockingAssert = false
	)		const [virtual]

Returns intersection of sphere with the terrain in the record irtFlag specifies what intersection data should be filled in for the record.

Implements DtTerrainImplementation.

virtual const DtVectorNetwork* DtEllipsoidTerrainImplementation::vectorNetwork

(

)

const [virtual]

Implements DtTerrainImplementation.

virtual bool DtEllipsoidTerrainImplementation::intersectVectorNetwork	(	const DtChord &	chord,
		DtVectorNetworkRecord *	vectorRecord,
		DtVectorNetworkIntersectionRecord *	vectorIntersectionRecord
	)		const [virtual]

User passes in the chord to intersect the vector network and the vectorRecord defining the desired search parameters like the kind of features to be searched.

Returns the best feature intersection and associated data in the vectorIntersectionRecord if there is an intersection. Returns false if there is no intersection.

Implements DtTerrainImplementation.

(

)

const [virtual]

Returns:

A DtTerrainCapabilites structure that describes the capabilities of the currently loaded terrain.
