Abstract

A method for compressing depth information for a three-dimensional virtual scene includes, at a computing device, recognizing a three-dimensional virtual scene including one or more locally-maintained virtual objects. Positioning information for one or more remotely-maintained virtual objects to be included in the three-dimensional virtual scene are received from a remote device. For a virtual view of the three-dimensional virtual scene having a virtual perspective, different portions of the virtual view are classified as belonging to one of a plurality of different occlusion classes, each of the plurality of different occlusion classes specifying an occlusion relationship between locally-maintained virtual objects and remotely-maintained virtual objects in the virtual view. A depth-compressed representation indicating the occlusion class for each of the different portions of the virtual view is output to the remote device.
