Abstract
A 3D data decoding apparatus for decoding coded data. The 3D data decoding apparatus includes an arithmetic decoder configured to arithmetically decode mesh displacement from the coded data, a context selection unit configured to select a context in the arithmetic decoding, and a context initialization unit configured to set an initial value of the context. In the context initialization unit, a context initialization parameter for initializing the context is decoded from the coded data.
