Which term refers to a painting or design intended to create the illusion of a three-dimensional object?

• A. Sgraffito
• B. Plein air
• C. Wet on wet
• D. Trompe l'oeil

Answer: (D)

Creating the illusion of three-dimensional form on a flat surface is the aim of trompe l’œil. This term, literally “deceive the eye,” describes paintings designed to look so real that viewers mistake them for actual objects or spaces. Artists achieve this with careful perspective, accurate shading, tonal variation, and precise edges to mimic depth, volume, and light. When you see a painted doorway, window, or still life that seems to pop out or recede beyond the frame, you’re looking at trompe l’œil.

Sgraffito is a scratching technique that reveals underlying layers for decorative texture, not illusion of depth. Plein air refers to painting outdoors to capture natural light and atmosphere. Wet on wet describes applying fresh paint onto wet paint to blend smoothly. These terms describe techniques or contexts rather than the specific goal of fooling the eye with depth.
