Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of two dimensional (2D) patches in an atlas frame and a camera offset for a camera. The patches are decoded and converted to a three dimensional (3D) patch coordinate system to obtain a point cloud frame. An offset matrix is determined based on the camera offset. The offset is then applied matrix to the point cloud frame.

Abstract: A method is implemented by a PCC decoder and comprises: receiving, by the PCC decoder, a point cloud bitstream; performing, by the PCC decoder, buffering of the point cloud bitstream based on a time, the performing comprising determining the time based on a delay and a delay offset; and decoding, by the PCC decoder, the point cloud bitstream based on the buffering. A method is implemented by a PCC decoder and comprises: receiving, by the PCC decoder, a point cloud bitstream; performing, by the PCC decoder, buffering of the point cloud bitstream based on a delay, the delay is based on a first delay and a second delay; and decoding, by the PCC decoder, the point cloud bitstream based on the buffering.

Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of two-dimensional (2D) patches in an atlas frame and a three-dimensional (3D) bounding box scale. The 2D patches are decoded. A point cloud is reconstructed by converting the 2D patches to a 3D patch coordinate system defined by each projection plane of the 3D bounding box. The 3D bounding box scale is applied to a 3D bounding box.
