Zero byte coding of attribute connectivity in polygon meshes

Abstract

Some aspects of the disclosure provide a method of mesh processing. The method includes receiving a bitstream of coded information of a mesh, the mesh includes a plurality of three-dimensional (3D) vertices in a 3D space, and at least a non-position attribute. The coded information includes a position connectivity of the plurality of 3D vertices in the 3D space. The method also includes determining whether the coded information of the mesh indicates that a non-position attribute connectivity of the non-position attribute corresponds to at least an extreme case, and determining the non-position attribute connectivity according to the position connectivity of the plurality of 3D vertices when the non-position attribute connectivity corresponds to the extreme case.
