Abstract
Determination of locations of multiple rectangular areas within a composite projection area formed on a projection surface by a projector array of multiple projectors. A location of a maximum rectangular area is determined within the composite projection area. Available regions comprise regions unoccupied by previously-located rectangular areas. The maximum rectangular area is removed from the available regions. The following are iteratively repeated: determining a location of a next maximum rectangular area and removing the next maximum rectangular area from the available regions, until a stopping condition is met. A list of determined locations for rectangular areas within the composite projection area is provided after the stopping condition has been met.
