1. An augmented reality system, comprising: a passable world model comprising a set of map points corresponding to one or more objects of the real world; a processor to communicate with one or more individual augmented reality display systems to pass a piece of the passable world model to the one or more individual augmented reality display systems, wherein the piece of the passable world model is passed based at least in part on respective locations corresponding to the one or more individual augmented reality display systems and wherein communication between the processor and the one or more individual augmented reality display systems includes asynchronous communication; and a set of object recognizers to recognize a set of objects of the passable world model, the set of object recognizers arranged as a ring of object recognizers that run on the passable world model data, wherein the ring of object recognizers comprises at least two object recognizers, and wherein a first object recognizer of the at least two object recognizers recognizes a first object, and a second object recognizer of the at least two object recognizers recognizes a subset of the first object.
