Abstract

Method and devices for coding point cloud data using an angular coding mode. The angular coding mode may be signaled using an angular mode flag to signal that a volume is to be coded using the angular coding mode. The angular coding mode is applicable to planar volumes that have all of their occupied child nodes on one side of a plane bisecting the volume. A planar position flag may signal which side of the volume is occupied. Entropy coding may be used to code the planar position flag. Context determination for coding may take into account angular information for child nodes or groups of child nodes of the volume relative to a location of a beam assembly that has sampled the point cloud. Characteristics of the beam assembly may be coded into the bitstream.
