Smooth video/image signal compression

An electronic device comprising:

• a non-transitory computer-readable storage medium;
• and
• one or more processors coupled to the non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium comprises program instructions that, when executed on the one or more processors, cause the electronic device to perform operations comprising:
• obtaining two-dimensional (2D) data sets corresponding to different attributes of three-dimensional (3D) content, each of the 2D data sets providing attribute values for locations within a common 2D coordinate system that associates the attribute values for the different attributes with respective portions of the 3D content;
• generating a single 2D image by combining the 2D data sets, wherein the attribute values corresponding to the different attributes are combined within the single 2D image;
• and
• encoding the single 2D image into a specialized format for transmission or storage.
