Abstract
Methods, devices and stream are disclosed to encode and decode a scene (such as a point cloud) in the context of a patch-based transmission of a volumetric video content. The present principles relate a method of dividing an atlas image in regions, a region being associated with a sector of the space of the scene and packing patches obtained by projecting points comprised in the associated sector only. The atlas and related metadata are encoded in a data stream; At the rendering, a set of sectors is selected based on the current field of the user. Only pixels of regions associated with the selected sectors are accessed to generate the viewport image representative of the scene viewed from the current point of view.
