1. A device for processing point cloud data, the device comprising:
one or more processors configured to process point cloud data; and
one or more memories coupled with the one or more processors,
wherein the one or more processors are configured to:
encode a geometry of the point cloud data; and
encode an attribute of the point cloud data based on the encoded geometry,
wherein the geometry indicates positions of points of the point cloud data, and
wherein the attribute indicates at least one of reflectance and color of the points,
wherein the points are predicted based on a predictive tree including nodes of the points,
wherein the predictive tree is generated based on azimuth information for the points,
wherein a bitstream includes information related to the azimuth information for the predictive tree.
