1. A three-dimensional data decoding method comprising:
performing motion compensation on a second point cloud by using motion from a decoded first point cloud to the second point cloud, to generate a third point cloud having a position which is a position of the second point cloud that is shifted based on the motion;
merging the first point cloud and the third point cloud, to generate a reference point cloud;
decoding an N-ary tree structure of a current point cloud using the reference point cloud, where N is an integer greater than or equal to 2; and
generating a decoded point cloud of the current point cloud from the N-ary tree structure of the current point cloud.
