1. A three-dimensional data encoding method, comprising:
encoding a current point cloud frame; and
generating a bitstream that includes the current point cloud frame encoded and first information,
wherein the first information is set to a first value or a second value, the first value indicating that a number of three-dimensional points included in each of leaf nodes of the current point cloud frame is greater than or equal to 1, the second value indicating that the number of the three-dimensional points included in each of the leaf nodes of the current point cloud frame is 1, and
when the current point cloud frame is a combined point cloud frame generated by combining a plurality of point cloud frames, the first information is not set to the second value.
