In painting, the attempt to make images that seemingly share or extend the three-dimensional space in which the spectator stands. . . . For imagery, the painter may represent a flat surface from which planes jut and recede to a slight depth—the range of effects properly known as trompe l’oeil—or alternatively sky and great distance: in both cases the effects of parallax are minimized. The illusion will be stronger if the image is lit in the same way as its location, and in murals it may also share the same architecture, extended into painted vistas.
