The study and consideration of it help the artist in rendering correctly effects of atmosphere, space, and distance. Of linear perspective there are two kinds: parallel and angular. In the simpler of these, parallel, all the horizontal lines that are at right angles to the central visual ray, or the line of vision, are shown parallel; and the lines which in nature go in the same direction as the line of vision, in a perspective rendering recede toward a point on the horizon directly before the spectator's eye. A familiar example is that of a floor marked off into square feet with the crosswise lines parallel to the horizon. A view of a huge checker-board placed on the floor with one edge directly before you would do to illustrate it. Most drawings requiring pictorial projection are made in angular perspective. In this method the principal object is placed in such a way that some corner or angle points toward the observer and the lines bounding its edges converge obliquely toward vanishing points. The best way to make perspective clear is to give a particular example and show the way of procedure from the beginning and carried through to the end.
