Trompe l’oeil

Trompe l’oeil (French for ‘deceive the eye’; /trɒmpˈlɔɪ/ tromp-LOY; French: [tʁɔ̃p lœj]) is an artistic technique that creates the realistic illusion of 3-D using multiple depth cues. By playing with perspective and detail, it gives the illusion that a flat, two-dimensional surface is a three-dimensional object or space, “deceiving” the viewer’s eye. Its applications are numerous: In painting and architecture, etc. It has been very popular since antiquity, and is often used to paint false windows, doors, or mouldings on a flat wall. 

Trompe-l’œils creates a highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface. Trompe-l’œil, which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture, and Op art is a modern style that mostly deals with geometric patterns that create similar visual effects,, including illusory depth.

A classic example is Pere Borrell del Caso’s painting Fleeing Criticism (1874), where a boy appears to step out of the frame. In pastry-making, it is a major culinary trend in which a dessert is modelled to closely resemble an everyday object or an unexpected food (such as a cake that looks like a whole lemon or a piece of cheese). In fashion, similar techniques have been used to create printed patterns that mimic the layering of clothing or the effect of a complex material construction (ref. spatial visual illusive effects).
