Systems and methods are described that enable augmented reality, virtual reality, and/or other content to be associated with precise geo-spatial locations in a physical environment. A model of a physical environment is accessed and a three dimensional mesh definition comprising a plurality of mesh cells is received where the mesh is associated with the physical environment. A given mesh cell is associated with a logical address. Augmented reality, virtual reality, and/or other content may be associated with a given mesh cell. Tracking data corresponding to movement of a user in the physical environment is received. The tracking data may be compared with mesh cell locations to identify matching mesh cells. Addresses associated with the matching mesh cells are used to identify associated content. The identified associated augmented reality, virtual reality, and/or other content may be rendered using an augmented reality, virtual reality, or other rendering device.
