Vanishing point of multipoint perspective, and historian Kirsti Andersen compiled these observations. She notes, in terms of projective geometry, the vanishing point is the image of the point at infinity associated with , as the sightline from through the vanishing point is parallel to . As a vanishing point originates in a line, so a vanishing line originates in a plane that is not parallel to the picture . Given the eye point , and the plane parallel to and lying on , then the vanishing line of is . For example, when is the ground plane and is the horizon plane,
The Point! inspiration for "The Point!": "I was on acid and I looked at the trees and I realized that they all came to points, and the little branches came to points, and the houses came to point. I thought, 'Oh! Everything has a point, and if it doesn't, then there's no point to it.'
