A processor-implemented method for streaming visible blocks of volumetric video to a client device during a predefined time period is provided. The method includes (i) receiving at least one block description file from a content server, (ii) processing each block description in the at least one block description file, to determine the visible blocks that are selected from a set of blocks, that are capable of being visible to a viewer of the client device during the predefined time period, based on a 3D position, size, and an orientation of each block in the set of blocks and at least one view parameter of a user of the client device, (iii) transmitting a request for the visible blocks, to the content server, and (iv) receiving the visible blocks as a visible blocks video at the client device. 1. A processor-implemented method for streaming a set of visible blocks of volumetric video that correspond to a predefined time period from a content server , the method comprising:receiving at least one block description file at a client device, wherein the at least one block description file comprises a set of block descriptions associated with the set of blocks for the predefined time period, wherein for each block in the set of blocks, a block description for each block comprises a 3D position, size, and an orientation of each block;processing each block description in the at least one block description file, at the client device, to determine the visible blocks that are selected from the set of blocks, wherein the visible blocks are a subset of the set of blocks, that are capable of being visible to a viewer of the client device within the predefined time period, wherein the visible blocks are determined based on the 3D position, size, and the orientation of each block in the set of blocks and at least one view parameter of a user of the client device;transmitting a request for the visible blocks, from the client device to the content server; andreceiving the visible ...
