1. A method of transmitting point cloud data, the method comprising:
encoding point cloud data, wherein the encoding of the point cloud data comprises:
encoding geometry for positions of one or more points of the point cloud data; and
generating Morton codes for the one or more points, wherein the Morton codes are generated by interleaving a value of a coordinate for the positions in an ascending order;
encoding an attribute of the one or more points; and
transmitting a bitstream including the encoded point cloud data,
wherein the bitstream includes an order of a coordinate axis of the position and information for representing a number of bits related to an axis of the coordinate.
