1. A method performed by at least one processor, the method comprising:
encoding a video stream, the encoded video stream including:
a frame of a plurality of two-dimensional (2D) pictures that are layers of the frame, each of the plurality of 2D pictures having a respective attribute of a same three-dimensional (3D) representation,
frame partition information that indicates the frame is partitioned into a plurality of sub-frames, each of the plurality of sub-frames being a respective combination of a sub-region of each picture of the plurality of 2D pictures, and
3D bounding box information that specifies a 3D position corresponding to a sub-frame of the plurality of sub-frames; and
sending the encoded video stream to a decoder,
wherein the frame partition information, of the encoded video stream, includes 2D bounding box information that specifies at least one among a position and boundary of the sub-frame in the frame,
the frame partition information further includes a syntax element that indicates whether a 2D bounding box specified in the 2D bounding box information includes only one tile, and
the 3D bounding box information specifies a 3D position of the 2D bounding box specified in the 2D bounding box information.
