Aperture
THEORY & MATHEMATICSbeginner
Definition
An opening or gap in a surface, particularly in a facade or wall. Apertures control light, ventilation, and views. They are fundamental compositional elements that affect how a building appears both from inside and outside.
Example
The precise, punched apertures of Marcel Breuer's Whitney Museum in New York (1966) create a stark, fortress-like character while controlling the quality of light inside.
