Claim One:
1. A method, comprising: receiving a plurality of left eye rays through one of a first plurality of separating facets of a lens at an image acquisition plane; and receiving a plurality of right eye rays through one of a second plurality of separating facets of the lens at the image acquisition plane, wherein at least one facet of the first plurality of separating facets has a surface normal vector N S1 determined by a surface normal angle Θ SN1 included between the surface normal vector N S1 and an incident vector I c1 to intersect at a point including a cross product vector comprising a cross product of the incident vector I c1 and a refracting vector R 1 , wherein the surface normal angle Θ SN1 is approximately equal to arctan ( 1 - ( I c ⁢ ⁢ 1 · R 1 ) 2 n 1 n 2 - ( I c ⁢ ⁢ 1 · R 1 ) ) , wherein the vectors N S1 , R 1 , and I c1 are included in a common plane, wherein the incident vector I c1 comprises a ray incident to the at least one facet and passing through a first viewpoint, wherein the refracting vector R 1 comprises a ray to be refracted by the at least one facet, wherein n 1 comprises an index of refraction corresponding to the incident vector I c1 , wherein n 2 comprises an index of refraction corresponding to the refracting vector R 1 , and wherein the surface normal vector N s1 is rotated around the cross product vector by the surface normal angle Θ SN1 in the common plane.
