Perspective (graphical) with one-point perspective. These parallel lines converge at the vanishing point. One-point perspective exists when the picture plane is parallel to two axes of a rectilinear (or Cartesian) scene – a scene which is composed entirely of linear elements that intersect only at right angles. If one axis is parallel with the picture plane, then all elements are either parallel to the picture plane (either horizontally or vertically) or perpendicular to it. All elements that are parallel to the picture plane are drawn as parallel lines. All elements that are perpendicular to the picture plane converge at a single point
Point-to-point (steeplechase) 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 lot of money. Whilst professional trainers are specifically excluded from running horses in point-to-points in Great Britain (other than their own personal horses), the days
