Perspective projection is a technique used in computer graphics and photography to create a realistic representation of three-dimensional objects on a two-dimensional surface. This method simulates how objects appear smaller as they get further away from the viewer, mimicking human vision. The result is a sense of depth and space, making images more lifelike. In perspective projection, lines from the object converge at a single point called the vanishing point. This point is typically located on the horizon line, which represents the viewer's eye level. By adjusting the position of the camera or the viewer, different perspectives can be achieved, enhancing the visual experience.
