Abstract: Methods and devices are disclosed to adapt a full-resolution 360° volumetric video content to the processing resources of different client devices. A 3D scene or a sequence of 3D scenes encoded as patch pictures, for example packed in atlas images is obtained; Patch pictures of the atlases are organized according to a sectorization of the three-dimensional space. Then, a request comprising information representative of a pose is received from a client device. Sectors of the sectorization are selected as a function of the pose information and the sectorization. The corresponding part is extracted and/or recomposed, encoded and transmitted to the client device.
