Vanishing point is below the horizon line, its vanishing lines angle up to the horizon line. If the object is above, they slope down. All vanishing lines end at the horizon line. 1. Projections of two sets of parallel lines lying in some plane appear to converge, i.e. the vanishing point associated with that pair, on a horizon line, or vanishing line formed by the intersection of the image plane with the plane parallel to and passing through the pinhole. Proof: Consider the ground plane , as which is, for the sake of simplicity, orthogonal to the image plane. Also, consider a
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
