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.

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,

	)		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

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)

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.
