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 Devil's Point easiest route is to follow the path leading up the Coire Odhar from Corrour Bothy, on the eastern side of the mountain. To reach the bothy requires a long walk in; the most usual route is to follow the Lairig Ghru from Linn of Dee, a distance of some . The Devil's Point is often climbed along with Cairn Toul. Sgòr an Lochain Uaine, which lies to the north of Cairn Toul is sometimes called "The Angel's Peak", in contrast to The Devil's Point. The Devil's Point The Devil's Point (Scottish Gaelic: Bod an Deamhain) is a mountain in the
