Claim 20:
21. An apparatus for decoding a volumetric video, the apparatus comprising a processor configured for:
receiving a data stream comprising information for selecting, according to a rendering viewpoint, at least one atlas comprising color and depth data patches acquired from a viewpoint in said volumetric video, said color and depth data patches being generated with respect to depth and color reference data acquired from a reference viewpoint in said volumetric video, wherein said information comprises a list of adaptive parallax parameters comprising:
a list of reference viewpoints comprising at least one reference viewpoint, and for each of said reference viewpoints:
associated coordinates of said at least one reference viewpoint in a volumetric cartesian coordinates system, and
at least one uniform resource identifier allowing to download an encoded data stream representative of an atlas associated with said reference viewpoint;

for each of said reference viewpoints in the list, a number of virtual cameras, each of said virtual cameras corresponding to a viewpoint in said volumetric video; and
for each of said virtual cameras:
associated coordinates of said viewpoint corresponding to said virtual camera in said 3D cartesian coordinates system, and

at least one uniform resource identifier allowing to download an encoded data stream representative of an atlas associated with said virtual camera.
