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

Claim 0:
1. 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 determine the intersections of the vectors between the inner region of the triangle face and each vector including a start origin located within a range of each of vertices of the triangle face.
