Horizon science of graphical perspective. Assuming the picture plane stands vertical to ground, and "P" is the perpendicular projection of the eye point "O" on the picture plane, the horizon is defined as the horizontal line through "P". The point "P" is the vanishing point of lines perpendicular to the picture. If "S" is another point on the horizon, then it is the vanishing point for all lines parallel to "OS". But Brook Taylor (1719) indicated that the horizon plane determined by "O" and the horizon was like any other plane: The peculiar geometry of perspective where parallel lines converge in
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
