Vanishing point to the axis which is cut by this image plane will have images that meet at a single vanishing point. Lines parallel to the other two axes will not form vanishing points as they are parallel to the image plane. This is one-point perspective. Similarly, when the image plane intersects two world-coordinate axes, lines parallel to those planes will meet form two vanishing points in the picture plane. This is called two-point perspective. In three-point perspective the image plane intersects the , , and axes and therefore lines parallel to these axes intersect, resulting in three different vanishing points. The
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
