- Vast performance increase when removing scene containing large number of objects: the sensor/controller map was updated for each deleted object, causing massive slow down when the number of objects was large (O(n^2)). - Use reference when scanning the sensor map => avoid useless copy. - Remove dynamically the object bounding box from the DBVT when the object is invisible => faster culling.
