A method for forming a reflective or refractive surface, comprising discretizing a two-dimensional image into a first mesh of first nodes on a first surface, wherein nodes on the first surface (2) define a first cell area A d,1 of the first mesh on which a first beam of light with a first radiant flux ¦ 1 is incident, wherein the first cell area A d,1 of the first mesh corresponds to an area of the two-dimensional image having a brightness to which the first radiant flux ¦ 1 corresponds; discretizing a reflective or refractive second surface into a second mesh of second nodes, wherein nodes on the second surface define a first cell area A s,1 of the second mesh on which the first beam of light with the first radiant flux ¦ i is incident and is deviated towards the first cell area A d,1 of the first mesh; and adjusting the positions of the nodes of the first cell area A s,1 of the second mesh on the second surface so that the first cell area A s,1 of the second mesh corresponds to a predefined radiant exitance M 1 of the first beam of light incident on the second surface. |
