Methods, displays and systems of three-dimensional displaying using electromagnetic field computations

Abstract

Methods, apparatus, devices, and systems for displaying objects in three dimensions (3D) are provided. In one aspect, a method includes: obtaining data including corresponding primitive data of primitives corresponding to the object; determining the electromagnetic field contribution of the primitives to the display elements by calculating the electromagnetic field propagation from each primitive to each display element of the display screen; generating a sum of electromagnetic field contributions of a plurality of the primitives to each display element; sending a corresponding control signal to each display element to modulate at least one characteristic of the display element based on the sum of electromagnetic field contributions; and sending a timing control signal to an illuminator to activate the illuminator thereby illuminating light onto the display screen, such that the modulated display elements of the display screen cause the light to form a volumetric light field corresponding to the object.
