Abstract: In certain embodiments, higher-level octree telepresence data for a point cloud of a 3D object is transmitted using a reliable transport mechanism that ensures successful transmission, e.g., via re-transmission of dropped packets, and lower-level octree data for the point cloud is transmitted using a non-reliable transport mechanism that does not guarantee successful transmission. When the lower-level data is contained in one or more of the bottom-most layers in the octree representation, at least some of the point cloud might be able to be reconstructed using successfully received data even when some lower-level data is lost and not re-transmitted. Using non-reliable transmission can reduce latency by avoiding time-consuming re-transmissions. The resulting reconstructed point cloud will be incomplete, but it might be sufficiently complete to provide satisfactory user experience with lower latency that using reliable transport for the entire octree.
