A strong diagonal line, created by a boy reclining on the couch, contrasts with the geometrical grid of the background window elements. In addition, the back wall of the room (which is governed by one-point perspective) contrasts in scale with the large shapes of the couch, generating a sense of deep space.

UTILIZING FORESHORTENING

Foreshortening, like perspective, is a drawing concept used to render spatial relationships. Foreshortening is used to indicate the relationship of near to far, or what comes forward and what recedes in space.

This simply means that anything (lines or planes) at an angle to the viewer will seem shorter than its true length. A test of this dynamic can be done with a pencil. If you hold the pencil parallel before your eyes, you observe its true length. Now turn one end away from you so that it moves back into space. Squint your eyes and notice how the pencil immediately appears shorter. The more you rotate the pencil away from you, the shorter it becomes visually. At this point, your mind is challenged to separate what it knows (the true length of the pencil) from what it perceives. To depict the illusion of the pencil in space, it must be rendered as you are visually observing it, not as you tactually or mentally know the pencil.
