Abstract
A device, an apparatus and associated methods are provided. In one embodiment, the method comprises obtaining a multi-plane image (MPI) representation of a three dimensional (3D) scene. The MPI representation includes a plurality of slices of content from the 3D scene, each slice corresponding to a different depth relative to a position of a first virtual camera. Each slice is decomposed into regular tiles; and the orientation of each tile is determined.

A method comprising:
- receiving a multi-plane image (MPI) representation of a three-dimensional (3D) image, the MPI representation comprising a plurality of slices, each slice of the plurality of slices corresponding to a different depth relative to a first position;
- decomposing each slice of the plurality of slices into a plurality of tiles;
- determining a position of each tile of the plurality of tiles within each slice of the plurality of slices;
- determining orientation information for selected tiles of the plurality of tiles within each slice of the plurality of slices, wherein the orientation information is relative to a position and depth of a tile within a respective slice;
- generating a stacked representation of the plurality of slices, wherein each slice of the stacked representation comprises a plurality of oriented tiles, wherein each oriented tile is oriented according to respective orientation information;
- and
- generating a merged image using the stacked representation, the merged image representing a view of the 3D image relative to a second position.
