Perspective (graphical) with one-point perspective. These parallel lines converge at the vanishing point. One-point perspective exists when the picture plane is parallel to two axes of a rectilinear (or Cartesian) scene – a scene which is composed entirely of linear elements that intersect only at right angles. If one axis is parallel with the picture plane, then all elements are either parallel to the picture plane (either horizontally or vertically) or perpendicular to it. All elements that are parallel to the picture plane are drawn as parallel lines. All elements that are perpendicular to the picture plane converge at a single point
The Ideal City (painting) attributed tentatively to Francesco di Giorgio Martini and dated eventually as 1477. "The Ideal City" celebrates the values in a well-ordered society, architecture stands as a metaphor for good government. The illusion of space is achieved using a mathematical perspective system developed in Florence. The receding lines that establish spatial relationships converge at a central point, located in the middle of the city gate. In a scene from the 1995 thriller, "Twelve Monkeys", Bruce Willis' character looks at "The Ideal City" in the Walters Art Museum. "The Ideal City" is one of the paintings available to buy virtually inside the
