1. A device for encoding point cloud data, the device comprising:
an encoder configured to encode a geometry data based on a predictive tree,
wherein the predictive tree is generated by sorting points of the geometry based on at least one of an azimuth or a Morton order for the points,
encode an attribute of the point cloud data based on the geometry; and
a transmitter configured to transmit a bitstream including the geometry and the attribute,
wherein the bitstream further includes method information for representing a method related to the predictive tree, and direction information for representing a direction related to prediction.
