Systems and methods are described for displaying a light field using a display device in which a plurality of internal light paths contribute to each respective output beam and in which each light path traverses at least one controllable-transparency pixel of the display. In example methods, a target light field is partitioned into a plurality of light field partitions that sum to the target light field. Each light field partition is associated with a subset of the internal light paths. Pixel values of the display device are selected to minimize a total error in each path's contribution to its corresponding light field partition. Methods described herein may be used to select pixel values in display devices that include a diffractive element, such as a diffraction grating.
