Claim 4:
5. A point cloud decoding method, implemented in a decoder and comprising:
decoding a bitstream to obtain a coordinate-axis-order index;
determining a processing order of point cloud data during point cloud decoding according to the coordinate-axis-order index, the processing order indicating a coordinate axis processing order of three-dimensional coordinates of the point cloud data and the point cloud data being all or part of data in point cloud;
decoding the bitstream to obtain recovered data of the point cloud data; and
determining a position of coordinate data of the point cloud data in a storage unit of the recovered data according to the processing order, wherein a correspondence table between preset indexes and processing orders comprises:, coordinate-axis-order index
