Octant *	GetOrCreateChild (unsigned index)
	Return or create a child octant.

void	DeleteChild (unsigned index)
	Delete child octant.

void	InsertDrawable (Drawable *drawable)
	Insert a drawable object by checking for fit recursively.

bool	CheckDrawableFit (const BoundingBox &box) const
	Check if a drawable object fits.

void	AddDrawable (Drawable *drawable)
	Add a drawable object to this octant.

void	RemoveDrawable (Drawable *drawable, bool resetOctant=true)
	Remove a drawable object from this octant.

const BoundingBox &	GetWorldBoundingBox () const
	Return world-space bounding box.

const BoundingBox &	GetCullingBox () const
	Return bounding box used for fitting drawable objects.

unsigned	GetLevel () const
	Return subdivision level.

Octant *	GetParent () const
	Return parent octant.

Octree *	GetRoot () const
	Return octree root.

unsigned	GetNumDrawables () const
	Return number of drawables.

bool	IsEmpty ()
	Return true if there are no drawable objects in this octant and child octants.

void	ResetRoot ()
	Reset root pointer recursively. Called when the whole octree is being destroyed.

void	DrawDebugGeometry (DebugRenderer *debug, bool depthTest)
	Draw bounds to the debug graphics recursively.

Protected Member Functions
void	Initialize (const BoundingBox &box)
	Initialize bounding box.

void	GetDrawablesInternal (OctreeQuery &query, bool inside) const
	Return drawable objects by a query, called internally.

void	GetDrawablesInternal (RayOctreeQuery &query) const
	Return drawable objects by a ray query, called internally.

void	GetDrawablesOnlyInternal (RayOctreeQuery &query, PODVector< Drawable * > &drawables) const
	Return drawable objects only for a threaded ray query, called internally.

void	IncDrawableCount ()
	Increase drawable object count recursively.

void	DecDrawableCount ()
	Decrease drawable object count recursively and remove octant if it becomes empty.

Protected Attributes

Octant *	children_ [NUM_OCTANTS]
	Child octants.

Vector3	center_
	World bounding box center.

Vector3	halfSize_
	World bounding box half size.

unsigned	level_
	Subdivision level.

unsigned	numDrawables_
	Number of drawable objects in this octant and child octants.

Octant *	parent_
	Parent octant.

Octree *	root_
	Octree root.

unsigned	index_
	Octant index relative to its siblings or ROOT_INDEX for root octant.
