[−][src]Trait broccoli::Aabb
Trait to signify that this object has an axis aligned bounding box. get() must return a aabb with the same value in it while the element is in the dinotree. This is hard for the user not to do, this the user does not have &mut self, and the aabb is implied to belong to self. But it is still possible through the use of static objects or RefCell/ Mutex, etc. Using this type of methods the user could make different calls to get() return different aabbs. This is unsafe since we allow query algorithms to assume the following: If two object's aabb's don't intersect, then they can be mutated at the same time.
