One-point perspective is a drawing technique used to create the illusion of depth on a flat surface. In this method, all parallel lines converge at a single point on the horizon, known as the vanishing point. This technique helps artists depict three-dimensional spaces realistically, making objects appear smaller as they recede into the distance. This perspective is commonly used in various forms of art, including architecture, landscape painting, and photography. By focusing on a single vanishing point, artists can guide the viewer's eye into the scene, enhancing the sense of space and dimension in their work.
