This class contains a Bullet btCollisionWorld, and also maintains ownership of the collision objects that are added to this world. This is the central class that can answer intersection queries with the currently loaded data.

DtCollisionWorld& DtCollisionWorld::operator= ( const DtCollisionWorld & )

privatedelete

Not implemented.

virtual void DtCollisionWorld::initialize ( )

virtual

virtual unsigned DtCollisionWorld::collisionObjectCount ( )

virtual

virtual unsigned DtCollisionWorld::collisionMeshCount ( )

virtual

Returns: The count of all unique collision meshes in the world. Multiple collision objects may share the same mesh.

Note: This may be slow.

virtual unsigned int DtCollisionWorld::uniqueTriangleCount ( )

virtual

Returns: The count of all unique triangles. This is the sum of all triangles in all meshes. Multiple collision objects may share a mesh.

Note: This may be slow.

virtual void DtCollisionWorld::addCollisionObjectToWorld	(	const std::shared_ptr< btCollisionObject > &	object,
		short int	objectGroup = `btBroadphaseProxy::DefaultFilter`
	)

virtual

virtual unsigned int DtCollisionWorld::removeCollisionObjectsFromWorld ( const DtCollisionObjectList & )

virtual

virtual void DtCollisionWorld::removeCollisionObjectFromWorld ( const std::set< long long > & OsmFidList )

virtual

This function will "hide" the geometries associated to the FID list provided in the bullet world.

virtual void DtCollisionWorld::enableHiddenCollisionObjectInWorld ( )

virtual

Reset all hidden geometries that have associated FID (to be used on rewind for example)

virtual void DtCollisionWorld::enableHiddenCollisionObjectInWorld ( const std::set< long long > & OsmFidList )

virtual

Reset hidden geometries from FID list.

virtual bool DtCollisionWorld::chordIntersect	(	const DtChord &	chord,
		DtVrfChordIntersectionRecord &	record,
		bool &	dataAvailable,
		DtIntersectionRecord::DtIntersectionType	irtFlag,
		short int	filterMask
	)		const

virtual

The dataAvailable flag will be set to false if this intersection encounters some data that cannot be intersected with. (Used when the BVH is being built in a background thread and hasn't finished yet)

virtual bool DtCollisionWorld::allIntersectsAlongChord	(	const DtChord &	chord,
		DtVrfChordIntersectRecordList &	intList,
		bool &	dataAvailable,
		DtIntersectionRecord::DtIntersectionType	irtFlag,
		short int	filterMask
	)		const

virtual

The dataAvailable flag will be set to false if this intersection encounters some data that cannot be intersected with. (Used when the BVH is being built in a background thread and hasn't finished yet)

virtual bool DtCollisionWorld::updateWorldTransform	(	btCollisionObject *	obj,
		const btTransform &
	)

virtual

virtual void DtCollisionWorld::setCoordinateSystem ( const Coordinate_System * cs )

virtual

virtual const Coordinate_System* DtCollisionWorld::coordinateSystem ( )

virtual

virtual void DtCollisionWorld::processTrianglesInArea ( DtBulletTriangleCallback & )

virtual

virtual void DtCollisionWorld::processTrianglesForGeometry	(	DtBulletTriangleCallback &	calllback,
		DtTerrainGeometryId	geometryId
	)

virtual

virtual long DtCollisionWorld::numberOfUnloadableTerrainTriangles ( ) const

virtual

Return the number of terrain triangles that are loaded initially and are not part of the terrain pager system.

virtual void DtCollisionWorld::setNumberOfUnloadableTerrainTriangles ( long value )

virtual

Set the number of terrain triangles that are loaded initially and are not part of the terrain pager system.

virtual std::shared_ptr<DtFidListMonitor> DtCollisionWorld::getFidListMonitor ( )

virtual

Creates and returns a new DtFidListMonitor. Deletion of this monitor (by removing all references) is sufficient to remove it from the system.

virtual void DtCollisionWorld::setFidHideFunction ( std::function< bool(const long long)> fcn )

virtual

Set the function that collision world will use to determine if FIDs are hidden or not.

virtual void DtCollisionWorld::enableMetrics ( bool value )

virtual

Enable or not debug metrics.

virtual void DtCollisionWorld::getMetrics ( CollisionMetric & collisionMetrics )

virtual

Get metrics (will reset values each time we get them)

virtual btCollisionWorld* DtCollisionWorld::bulletCollisionWorld ( )

protectedvirtual

virtual void DtCollisionWorld::deleteInternalMemberVariables ( )

protectedvirtual

delete internal member variables

virtual void DtCollisionWorld::notifyFidListMonitors ( )

protectedvirtual

Notifies all monitors on the FID List Monitor list of a FID list change.

virtual bool DtCollisionWorld::isFidHidden ( const long long fid )

protectedvirtual

virtual void DtCollisionWorld::calculateMeshAndTriangleCount ( )

protectedvirtual

Calculates myNumCollisionShapes and myNumTrianglesOfAllShapes if dirty. This can be slow if recalculation is needed.

virtual void DtCollisionWorld::resetMetrics ( )

protectedvirtual

reset metrics values
