1. A computer-implemented method comprising:
receiving a first data set comprising a three-dimensional description of a scene;
partitioning the first data set into a plurality of layers comprising a set of inner frustum volume layers and a set of outer frustum volume layers, each layer representing a portion of the scene at a location with respect to a reference location;
obtaining, for each of the plurality of layers, one or more polygons representative of corresponding portions of objects in the scene;
determining, based on the one or more polygons, a view-independent representation; and
encoding the view-independent representation as a portion of a second data set, wherein a size of the second data set is smaller than a size of the first data set.
