Abstract
A method includes accessing map data of an area of a real environment, the map data comprising three-dimensional feature descriptors describing features visible in the real environment. A plurality of map packages are generated based on the map data, wherein each of the map packages (1) corresponds to a two-dimensional sub-area within the area of the real environment, and (2) comprises a subset of the three-dimensional feature descriptors describing features visible in the sub-area. A first sequence of the plurality of map packages are broadcast through one or more base stations, wherein the first sequence is based on the two-dimensional sub-area of each of the map packages, wherein each of the map packages is configured to be received and used by an artificial-reality device to determine a pose of the artificial-reality device in the associated sub-area based on the associated subset of the three-dimensional feature descriptors.
