A vanishing point is a key concept in perspective drawing and art. It refers to the spot on the horizon line where parallel lines appear to converge as they recede into the distance. This technique helps create the illusion of depth and three-dimensionality on a flat surface. In a typical scene, such as a straight road or railway tracks, the sides of the road or tracks will seem to meet at the vanishing point. Artists and architects use this principle to guide the viewer's eye and enhance the realism of their work, making it an essential tool in fields like architecture and graphic design.
