Abstract: An arithmetic coding scheme is provided for coding and decoding 3D data and improves coding efficiency for mesh displacements and high-quality coding, and decoding of the 3D data. A 3D data decoding apparatus is also provided for decoding coded data. The apparatus contains an arithmetic decoder that is configured to arithmetically decode a mesh displacement from the coded data. The arithmetic decoder decodes, from the coded data, a first flag indicating whether a coefficient of the mesh displacement has an absolute value greater than 0, a second flag indicating whether the coefficient has an absolute value greater than 1, and a third flag indicating whether the coefficient has an absolute value greater than 2.
