1. A decoding device for point cloud decoding, the decoding device comprising:
a communication interface configured to receive a bitstream; and
a processor operably coupled to the communication interface, the processor configured to:
identify, from the bitstream, messages and one or more sub-bitstreams representing a three-dimensional (3D) point cloud, wherein a sub-bitstream of the one or more sub-bitstreams includes independently encoded tiles,
identify a query label indicating an object of the 3D point cloud for decoding,
in response to determining that the query label corresponds to a label included in the messages, identify a 3D scene object associated with the query label based on the label,
identify a 2D tile that correspond to the 3D scene object, wherein the 2D tile is one of the independently encoded tiles, and
determine to decode, based on an identification of the 2D tile from the sub-bitstream, a portion of the sub-bitstream corresponding to the 2D tile to generate a portion of a video frame representing a portion of the 3D scene object.
