Zusammenfassung:	The embodiments relate to a method comprising receiving (1311) a volumetric video comprising a three-dimensional object; segmenting (1312) the three-dimensional object into a plurality of regions; for one or more regions of a three-dimensional object (1313): inserting into a bitstream or signaling along a bitstream a signal indicating one or more of the following: intra frame offset relating to three-dimensional geometry value (Z) between two regions within a frame; inter frame offset relating to three-dimensional geometry value (Z) between two regions in different frames; depth smoothness constraint relating to three-dimensional geometry value (Z) and transmitting (1314) the bitstream to a decoder. The embodiments relate to a method for receiving and decoding the bitstream, as well as to technical equipment for implementing any of the methods.
