Fig. 1. The Point of Sight is that point to which the eye of the spectator is supposed to be directed when he looks straight before him.
Fig. 2 The Horizon (or Horizontal Line) resembles that horizon or boundary line that seems to part the sea from the sky, forming this apparent line of conjunction.
Fig. 3. The Horizon Line in a picture is determined by the elevation or depression of the point of sight. The point of sight is determined by the real or supposed position of the spectator. (See Fig. 1.)
Fig. 4. If the position of the spectator, or artist, is low, as in Fig. 3. the point of sight and horizon line will be correspondingly low. On the other hand, if the artist ascends, the point of sight and horizon line ascend with him.
Fig. 5. Shows the four principal points and lines in perspective. The human figure is emblematical, and not to be considered as part of the picture any more than are the dotted lines.
Note that the lines A and B from the point of station to the horizon line and vanishing points are at right angles. The angles of such lines should always be right angles, or 90 degrees, in their relations with the vanishing points on the horizon line.
Fig. 6. The horizon line, one vanishing point, the point of sight and the point of station having been determined, the other vanishing point is found by proceeding according to the diagram Fig. 7.
Fig. 7. Project a line at right angles to the line A (connecting line between determined vanishing point [see Fig. 6] and point of station), and where it intersects the horizon line is the second vanishing point. By similar means the point of station can be found by having determined the point of sight and the vanishing points.
Fig. 8. All lines above the horizon line that are not parallel with the picture descend to the horizon line. All lines below the horizon line not parallel with the picture rise to the horizon line.
