Abstract
Processing circuitry decodes, from a bitstream carrying a 3D mesh, coordinates of vertices in the 3D mesh. The 3D mesh represents a surface of an object with polygons, the polygons are defined by the vertices and an original connectivity having original edges connecting the vertices. The processing circuitry derives an inferred connectivity according to the coordinates of the vertices, the inferred connectivity has inferred edges connecting the vertices. The processing circuitry decodes, from the bitstream, connectivity differences. In an example, the connectivity differences are associated with a subset of the vertices. In another example, the connectivity differences are associated with one or more edges in the original edges and the inferred edges. The processing circuitry determines a recovered connectivity according to the inferred connectivity and the connectivity differences, and reconstructs the 3D mesh according to the recovered connectivity.
