Locating the Point of Station. The point of station may be determined by having located both of the vanishing points. Or one vanishing point may be determined, which, together with the point of station, will determine the other vanishing point.
Two lines drawn from each of the vanishing points to the point of station should invariably form a right angle.
In the study of perspective it will be helpful to keep the following definitions and rules in mind. Even those already versed in art, through disuse, are prone to forget some of the simplest definitions.
Additional Elementary Rules
A right line is a perfectly straight line in a position or direction. Parallel lines are lines which are the same distance from each other throughout their length, whether straight or curved.
A horizontal line is one which is parallel to the earth's surface or the sea level.
A vertical line is a perfectly upright one, pointing to the vertex or zenith and to the center of the earth.
A perpendicular line is a line at right angles to any other straight line, but is not necessarily vertical.
A plane is a perfectly level surface, which may be either horizontal, vertical, or inclined in any direction.
A straight rod applied to any such surface would touch it throughout its length and breadth. A line is said to be in a certain plane when throughout its length it touches the plane, or coincides with it. In perspective, the picture plane is the surface, paper, canvas or whatever it may be upon which the drawing is made. This is always supposed to be at right angles to the direction in which the spectator is looking. If we are standing erect, and looking straight in front of us, the picture plane will be vertical; for instance, if the picture were placed close to an ordinary wall, the picture plane would be vertical. A point on the picture plane exactly opposite the eye is called the center of vision. The horizontal line indicates on the paper the position of the natural horizon. It will be higher or lower, according to the position of the spectator. If the latter stands on a hill, the horizon line would be high. If he stands on a level with the sea beach, the horizon line will be low.
