| 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. | |
| i32 | GetLevel () const |
| Return subdivision level. | |
| Octant * | GetParent () const |
| Return parent octant. | |
| Octree * | GetRoot () const |
| Return octree root. | |
| i32 | 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 ray query, called internally. | |
| void | GetDrawablesOnlyInternal (RayOctreeQuery &query, Vector< 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 | |
