3D DATA DECODING APPARATUS AND 3D DATA CODING APPARATUS

原文（中国語）

A 3D data decoding apparatus for decoding mesh data or point cloud data includes an atlas information decoder configured to decode atlas information from coded data in which the mesh data or the point cloud data is encoded, and a mesh reconstructor configured to decode a mesh from the coded data and the atlas information. The mesh reconstructor decodes any mesh/submesh from the coded data by using a parameter that indicates correspondence between tile information having any tile ID decoded in the atlas information decoder and submesh information having any submesh ID.
