Abstract
Some aspects of the present disclosure provide a mesh processing method. The method includes receiving a bitstream including encoded information of a polygon mesh, the polygon mesh including a plurality of vertices connected into a plurality of polygon faces, the encoded information including dual connectivity information of the polygon mesh and a residual of a geometry predictor of the polygon mesh. The method further includes reconstructing at least a first connectivity of a first polygon face according to the dual connectivity information, the first connectivity of the first polygon face indicating how a first set of vertices of the plurality of vertices are connected to each other to form the first polygon face. In addition, the method includes triangulating the first polygon face into a first set of triangles, and determining first geometry information of the first set of vertices based on the first set of triangles.
