Claim 11:
12. An image decoding method comprising:
decoding a bitstream to derive octree data;
deriving voxel data based on the octree data;
deriving mesh data based on the voxel data;
defining the mesh data within a bounding box;
setting vectors parallel to sides of the bounding box to have an interval based on a specified resolution of voxels;
determining intersections of the vectors with an inner region of a triangle face of the mesh data; and
generating point cloud data having coordinate values based on the determined intersections,
wherein the setting of the vectors includes setting the interval based on a product of a quantization size for the bounding box and a specified natural number corresponding to the specified resolution of voxels.
