1. A system comprising:
a display comprising a plurality of display elements;
an optical device adjacent to the display, wherein the optical device comprises a substrate and an optically diffractive element disposed on the substrate and configured to diffract light to the display; and
a driving device coupled to the display and configured to:
obtain a hologram for the display, wherein the hologram comprises, for each display element of the plurality of display elements, a respective sum of electromagnetic (EM) field contributions of a plurality of primitives corresponding to at least one object to the display element; and
generate, for each display element of the plurality of display elements, a respective modulation control signal based on the respective sum of EM field contributions of the plurality of primitives to the display element.
