1. A decoding device for generating partial access metadata for video-based point cloud compression, the decoding device comprising:
a communication interface configured to receive a compressed bitstream and metadata related to the compressed bitstream;
a processor operably coupled to the communication interface, wherein the processor is configured to:
identify, in the metadata, region information that indicates a region of a point cloud based on a user perspective;
locate a track of the compressed bitstream that corresponds to the region information;
identify, in the track, objects corresponding to the region of the point cloud; and
decode for display of an object, included in the objects identified in the track, that is visible from the user perspective.
