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,
Point-to-point (steeplechase) for prize money and meeting costs. There was opposition to the 2016 act's increased authority as interfering in a system that was already working well. Point-to-point (steeplechase) A point-to-point is a form of horseracing over fences for hunting horses and amateur riders. In Ireland, where the sport is open to licensed - i.e. professional - trainers, many of the horses will appear in these races before they compete in National Hunt races. Consequently, the Irish point-to-point is more used as a nursery for future young stars: a horse that wins its debut point-to-point in Ireland will often sell for a
