[Figure 8] Shot SF-01 shadow detail with 512 pixels square shadow-map resolution (top), and with 2,048 pixels square shadow-map resolution (bottom).

[Figure 9] Shot SF-03 showing the special desk lamp light.

Of note, relating to the key-light, is a special light added for shots SF-01 and SF-03. The desk lamp providing the primary source of illumination for the scene is just behind the computer, in the screen-right corner of the cubicle. The light itself is not visible from the camera, but its affect on the wall is. The desk lamp is aimed at the wall and the resulting light bounces to illuminate the cubicle. Because the renderer is scan line and not ray traced, this effect is simulated with two lights. The key-light shines out onto the scene as the light bounces from the wall. A special light for the desk lamp shines from the desk up onto the cubicle wall (see Figure 9). The only illumination provided by the desk lamp visible from the camera is on the far wall of the cubicle.
