Linear perspective revolutionized Renaissance art by providing a mathematical system to create the illusion of three-dimensional depth on a flat surface. Before its adoption, many paintings depicted objects independently of one another, resulting in a compressed, shallow space.12

The technique, formalized by Filippo Brunelleschi and later documented by Leon Battista Alberti, relies on three essential components:
* Orthogonals: Parallel lines that converge at a single vanishing point on the horizon line.12
* Scale reduction: Objects are rendered increasingly smaller as they recede toward the vanishing point, mimicking how the human eye perceives distance.12
* Rational structure: The system ensures all elements in a composition maintain a consistent, logical relationship to one another and to the viewer.3

By controlling the observer's viewpoint, artists created a "window to the world" where the painting’s space and the viewer's real-world environment became visually unified. This allowed the observer to feel as though they were participating in the scene, marking a significant shift toward perceptual realism in Western painting.32
