1. A method, using a computer, for generating stereoscopic content from a three-dimensional representation of a light field representing virtual or actual light rays from a scene, wherein the representation is readable in electronic form, the method comprising: capturing the three-dimensional representation of the light field, wherein the light field includes a plurality of input images; receiving a user-defined two-dimensional map including a set of goal binocular disparities for each pixel of a first image of a stereoscopic image pair with respect to a corresponding pixel of a second image of the stereoscopic image pair, wherein a first goal binocular disparity defined in the two-dimensional map for a first group of pixels is greater than a second goal binocular disparity defined in the two-dimensional map for a second group of pixels; determining a non-planar surface cut through the three-dimensional representation of the light field, wherein the non-planar surface cut is determined using the received two-dimensional map; determining a first two-dimensional subset and a second two-dimensional subset of the three-dimensional representation of the light field, wherein at least one of the first two-dimensional subset and the second two-dimensional subset corresponds to the non-planar surface cut; and generating, using the computer, the first image of the stereoscopic image pair using the first two-dimensional subset and the second image of the stereoscopic image pair using the second two-dimensional subset.
