1. A method comprising:

for each of a plurality of primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each of a plurality of display elements of a display by computing, in a three-dimensional (3D) coordinate system, EM field propagation from the primitive to the display element based on a predetermined expression for a primitive type that the primitive belongs to, different primitive types corresponding to different predetermined expressions, wherein a primitive represents a geometric or a graphical element for input or output within a computing system and is defined by one or more vertices; and

for each of the plurality of display elements, generating a sum of the EM field contributions from each of the plurality of primitives to the display element.
