Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 13:
14. An image decoding apparatus comprising:
circuitry configured to
decode a bitstream to derive octree data,
derive voxel data based on the octree data,
derive mesh data based on the voxel data,
define the mesh data within a bounding box,
set vectors parallel to sides of the bounding box to have an interval based on a specified resolution of voxels,
determine intersections of the vectors with an inner region of a triangle face of the mesh data, and
generate point cloud data having coordinate values based on the determined intersections,

wherein the circuitry is configured to set the vectors to have the interval between the vectors based on a product of a quantization size for the bounding box and a specified natural number corresponding to the specified resolution of voxels.
