1. A three-dimensional data encoding method comprising:
obtaining a plurality of three-dimensional points;
generating a prediction tree using the plurality of three-dimensional points;
predictive-encoding geometry information of the plurality of three-dimensional points using the prediction tree; and
generating a bitstream including encoded data obtained from the predictive-encoding, a total number of three-dimensional points included in the prediction tree, and identification information indicating whether or not to rearrange the plurality of three-dimensional points in Morton order.
