Isovist

An isovist is the visible area from a specific point within a space, like what you can see when standing at a particular location. It maps out all the surrounding areas visible without moving, considering walls, obstacles, and openings. Isovists are useful for understanding sightlines, navigation, and spatial awareness in environments such as buildings, city layouts, or outdoor spaces. They help architects, urban planners, and designers analyze how spaces are experienced visually and how visibility influences movement and safety. Essentially, an isovist captures the boundaries of your visible environment from one vantage point.
