1. A display system comprising:
one or more light sources;
one or more spatial light modulators that modulate light emitted by the one or more light sources in accordance with at least one of a phase or an amplitude modulation to generate modulated light, wherein the at least one of a phase or an amplitude modulation is computed based on two-dimensional (2D) or three-dimensional (3D) content to be displayed; and
a plurality of scatterers, wherein the one or more spatial light modulators direct the modulated light towards a subset of scatterers included in the plurality of scatterers, and wherein the modulated light is scattered by the subset of scatterers to display the 2D or 3D content.
