Abstract: An asynchronous, distributed, and calibrated apparatus provides a composite display from a plurality of plug-and-play projectors. The apparatus comprises a plurality of self-sufficient modules. Each module comprises at least one plug-and-play projector of the plurality of plug-and-play projectors. A camera is coupled to the projector. A software or firmware controlled, computation and communication circuit is coupled to the projector and executes a single-program-multiple-data (SPMD) calibration algorithm that simultaneously runs on each self-sufficient module to generate a scalable and reconfigurable composite display without any need for user input or a central server.
