Abrégé
(EN) A three-dimensional data encoding method generates a bitstream by encoding position information and one or more items of attribute information for each of a plurality of three-dimensional points included in point cloud data (S8781), and in said encoding (S8781), encodes a normal vector for each of the plurality of three-dimensional points as one item of attribute information included in the one or more items of attribute information. For example, the three-dimensional data encoding method may, in the encoding (S8781), encode the aforementioned normal vector, which is represented by a floating point, upon converting the vector to an integer.
(ZH) 三维数据编码方法通过对点群数据中包含的多个三维点各自的位置信息及1个以上的属性信息进行编码来生成比特流(S8781),在编码(S8781)中,将多个三维点各自的法线矢量作为1个以上的属性信息中包含的1个属性信息进行编码。例如,也可以是,三维数据编码方法在编码(S8781)中,在将用浮动小数点表现的所述法线矢量变换为整数的基础上进行编码。
