FIGURE 4.7 Screen grab from OpenSim showing a virtual interpretation of hierarchy in 3D composition. Note the
relative importance of objects in the visual eld, and how the less-important elements in the foreground lead the eye to
the most important element in the center of the image. This effect is achieved by shrinking and lowering the foreground
objects, while enlarging and raising the background object. The linear pattern on the ground also moves the eye toward
the focal point on the largest object.
