To reach that aim, first data representative of texture of the 3D scene visible according to a first viewpoint is encoded into one or more first tracks, the first data being arranged in first tiles of a first frame, a part of the 3D scene being associated with each first tile; second data representative of depth associated with points of the 3D scene is encoded into one or more second tracks, the second data being arranged in second tiles of a second frame, the total number of second tiles being greater than the total number of first tiles, a set of second tiles being allocated to each first tile and patches are arranged in the set of second tiles a set, each patch corresponding to a two-dimensional parametrization of a group of 3D points comprised into the part of the 3D scene associated with each first tile and comprising second data representative of depth associated with the 3D points of the group; and instructions to extract at least a part of the first data and second data from at least a part of the at least a first track and at least a second track are further encoded into one or more third tracks.
