Abstract: A processor-implemented method of generating a three-dimensional (3D) volumetric video with an overlay representing visibility counts per pixel of a texture atlas, associated with a viewer telemetry data is provided. The method includes (i) capturing the viewer telemetry data, (ii) determining a visibility of each pixel in the texture atlas associated with a 3D content based on the viewer telemetry data, (iii) generating at least one visibility counts per pixel of the texture atlas based on the visibility of each pixel in the texture atlas, and (iv) generating one of: the 3D volumetric video with the overlay of at least one heat map associated with the viewer telemetry data, using the at least one visibility counts per pixel and a curated selection of the 3D volumetric content based on the viewer telemetry data, using the visibility counts per pixel.

Abstract: 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.

Abstract: A processor implemented method for compressing time-varying surface data of a 3 dimensional object in a global digital space having frames, using a video encoder that supports a video data compression algorithm, the video encoder being coupled to a transmitter. The method includes the steps of (i) decomposing the time-varying surface data into at least one surface representation that is encoded in an oriented bounding box, (ii) transforming the oriented bounding box into a canonical camera representation for each frame to obtain canonical coordinates for the at least one surface representation, (iii) converting each of the at least one surface representation into at least one bounding box video pair that includes a grayscale video representing depth, and a color video and (iv) tiling the at least one bounding box video pair for each frame to produce a tiled bounding box video.
