Abstract
A method of encoding a point cloud into a bitstream of encoded point cloud data representing a physical object is provided. The method includes an azimuthal coding mode providing a series of bits for encoding a coordinate of a point of the point cloud. The method includes: dividing a parent interval, to which the point coordinate belongs to, into a left half interval and a right half interval; interpolating a left angle (φ), associated with the left half interval, and a right angle (φ), associated with the right half interval, from at least one inherited angle associated with the parent interval; selecting a context depending on the left angle (φ) and the right angle (φ); and context-adaptive binary entropy encoding a bit (b), into the bitstream, based on the selected context, the coded bit (b) indicating which of the two half intervals the point coordinate belongs to.
