1. A method, comprising:

  • identifying a first surface within a three-dimensional (3D) scene, wherein the 3D scene includes a first set of 3D objects located within a first depth range of the 3D scene and a second set of 3D objects located within a second depth range of the 3D scene, and 3D information defines the first set of 3D objects and the second set of 3D objects;

    projecting, by a processing unit, the first set of 3D objects onto the first surface according to a first projection mapping specified by a first focal length to produce a first portion of image components;

    projecting, by the processing unit, the second set of 3D objects onto the first surface according to a second projection mapping specified by a second focal length to produce a second portion of image components; and

    generating, by the processing unit, a first resulting image comprising the first portion of image components according to the first focal length and the second portion of image components according to the second focal length based on a camera projection from the first surface to a camera view plane.
