One-point perspective is a drawing technique used to create the illusion of depth and space on a flat surface. In this method, all parallel lines converge at a single point on the horizon line, known as the vanishing point. This technique helps artists depict three-dimensional objects realistically, making them appear to recede into the background. In one-point perspective, the viewer's eye is typically positioned directly facing the front of an object, such as a road or a building. This approach is commonly used in art, architecture, and photography to guide the viewer's gaze and enhance the sense of realism in the composition.
