Method and apparatus for entropy coding in dual degree mesh coding

A method performed by at least one processor, the method comprising:

• generating a bitstream comprising an encoded three dimensional polygon mesh in accordance with dual degree connectivity comprising, when the polygon mesh comprises at least two different face degrees, a first sequence representing a vertex degree of each vertex in the polygon mesh, and a second sequence representing a face degree of each face in the polygon mesh,
• wherein each vertex degree in the first sequence and each face degree in the second sequence is followed by a degree offset, and
• wherein at least one degree corresponding to a vertex degree in the first sequence or a face degree in the second sequence is encoded in accordance with a context adaptive binary arithmetic coding (CABAC) model that encodes the at least one degree using a difference between the at least one degree and a degree mode that indicates a number of different types of face degrees.
