Abstract

See full text

Aspects of the disclosure provide methods and apparatuses for mesh coding (encoding and/or decoding). In some examples, an apparatus for coding mesh includes processing circuitry. The processing circuitry decodes, using a point cloud compression (PCC) decoder and from a bitstream, a point cloud that includes first points corresponding to vertices in a three dimensional (3D) mesh frame. The 3D mesh frame represents a surface of an object with polygons. The processing circuitry decodes, from the bitstream, first connectivity information of the 3D mesh frame. The first connectivity information has been signaled in the bitstream. The processing circuitry infers, second connectivity information of the 3D mesh frame, from the first points of the point cloud. The second connectivity information is not signaled in the bitstream. The processing circuitry reconstructs the 3D mesh frame based on the point cloud, the first connectivity information and the second connectivity information.
