1. A method implemented by a decoder, comprising:
receiving a bitstream comprising a plurality of two-dimensional (2D) patches in an atlas frame and a scene object information (SOI)_three-dimensional (3D) bounding box scale log2 (soi_3d_bounding_box_scale_log2), wherein the atlas frame contains atlas samples onto which the 2D patches are projected to correspond to a volumetric frame, and wherein the soi_3d_bounding_box_scale_log2 is a parameter that indicates a 3D bounding box scale to be applied to a 3D bounding box;
decoding the 2D patches;
reconstructing a point cloud by converting the 2D patches to a 3D patch coordinate system defined by each projection plane of the 3D bounding box; and
applying the 3D bounding box scale to the 3D bounding box.
