In perspective, to represent (a figure) in such a manner as to convey to the mind the impression of the entire length of the object, though only a part of this length is actually shown, as when the object is viewed in an oblique direction; represent (any object, as an arm, a weapon, the branch of a tree) as pointing more or less directly toward the spectator standing in front of the picture, or as in a plane more or less nearly parallel to the spectator's line of sight.
