摘要：
A three-dimensional data encoding method includes: adding a first information item to a bitstream, the first information item indicating whether a duplicated point is available, the duplicated point representing, using a single node, position information items of two or more three-dimensional points having a same position information item in a prediction tree showing a reference relation in predictive encoding; and adding second information items to the bitstream when the first information item indicates that the duplicated point is available, the second information items each corresponding to a different one of nodes included in the prediction tree, and indicating a total number of one or more three-dimensional points included in the different one of the nodes.
