Systems and methods for encoding a video stream are provided. A method includes signaling partitioning information in a coded bitstream that is based on a point cloud. The coded bitstream may be a coded video stream that includes 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.
