In the example in Figure 4-29, the front (and back) face of each original
cube has been scaled to twice its original size (200 percent). The orange-black
cube is proportionally scaled. This means that all sides of the cube also doubled
in size. Notice how each side of the new cube has four checkerboard squares on
each edge. The original cube has two checkerboard squares on each edge.

A—When a cube is shown in a wireframe view, edges and vertices that would be hidden
in a shaded view are visible. B—Compare this view to Figures 4-26B and 4-27B.
C—When the cube is rotated to show the front face, it does not look like a square. This is
due to the wireframe display and the edges receding to the vanishing point.
