1. A method comprising:
accessing image data that comprises a texture data and a depth map;
decomposing the depth map into a plurality of component depth maps (CDMs) for a plurality of depth ranges, wherein each component depth map corresponds to a focal plane of a multiple focal plane (MFP) decomposition of the image data;
generating a plurality of component depth map focal planes (CDMFPs) by combining each respective CDM with the depth map;
scaling data in each CDMFP, wherein each respective CDMFP is scaled by a respective scaling factor;
generating a plurality of encoded scaled CDMFP data streams for the plurality of depth ranges, wherein each respective scaled CDMFP data stream is based at least in part on a respective scaled CDMFP; and
transmitting the plurality of encoded scaled CDMFP data streams to a client device to cause the client device to:
reconstruct the depth map based on a plurality of decoded scaled CDMFPs; and
generate for display an image based on the reconstructed depth map.
