When the observer stands close to the subject, the vanishing points are relatively close together (see top view) ■ and the cone of vision includes only a few cubes at the center. Cubes outside the cone of vision are excessively distorted and therefore unrealistic (see picture above).
But when the observer steps back, the cone of vision includes more of the subject, the vanishing points spread * apart, and the distortion is eliminated
THEREFORE: If too much distor-
tion appears in one of your drawings, either spread the * vanishing points apart (which means you have "stepped back" from thé subject) OR show only the undistorted center area (which means you're respecting a realistic cone of vision).
