Claim 4:
5. The method of claim 1, wherein the plurality of maps lacks an occupancy map, and the reconstructing at least the first vertex according to the first sampling rate and the second vertex according to the second sampling rate further comprises:
decoding information from the bitstream that indicates first boundary vertices for the first region;
inferring a first occupied region in an occupancy map corresponding to the first region according to the first boundary vertices;
obtaining, UV coordinates of an occupied point in the first occupied region, the occupied point corresponding to the first vertex;
converting the UV coordinates to sampled UV coordinates according to at least the first sampling rate; and
reconstructing, based on the plurality of maps, the first vertex according to the sampled UV coordinates.
