Abstract
A three-dimensional data encoding method includes: generating quantized values by quantizing, using one or more first parameters for one or more groups to which one or more attribute information belong, a coefficient value calculated for each node included in a layered structure of three-dimensional points. At least one attribute information belongs to any of the one or more groups. The calculating includes calculating, using two first coefficient values of two first nodes of a first layer, a second coefficient value of a second node of a second layer which is one layer higher. The quantizing includes: shifting-up the one or more first parameters by N bits (N is a natural number); shifting-down, by one bit, a sum of two second parameters of the two first nodes; shifting-down the result by N bits; and quantizing the second coefficient value using the obtained parameter.
