? aligned(8) class PCCBoundingBoxStruct( ){ unsigned int(8) num_boundingbox; for (i = 0; i < num_ boundingbox; i++) { BoundingBox(i); } } aligned(8) class BoundingBox (i){ unsigned int(8) boundingbox_id[i]; unsigned int(32) boundingbox_offset_x[i]; unsigned int(32) boundingbox_offset_y[i]; unsigned int(32) boundingbox_offset_z[i]; unsigned int(32) boundingbox_scale_x_factor[i]; unsigned int(32) boundingbox_scale_y_factor[i]; unsigned int(32) boundingbox_scale_z_factor[i]; unsigned int(32) boundingbox_size_width[i]; unsigned int(32) boundingbox_size_height[i]; unsigned int(32) boundingbox_size_depth[i]; }

bounding_box_id[i] indicates the identifier of the i-th bounding box in a coordinate system (e.g., the Cartesian coordinate system).
