425simplest of scenes can be made to look extremely realistic when it is lit accu-
rately. The classic “Cornell box” scene, shown in Figure 10.19, is an excellent
example of this.
The following sequence of screen shots from Naughty Dog’s Uncharted:
Drake’s Fortune is another good illustration of the importance of lighting. In
Figure 10.20, the scene is rendered without textures. Figure 10.21 shows the
same scene with diff use textures applied. The fully lit scene is shown in Fig-
ure 10.22. Notice the marked jump in realism when lighting is applied to the
scene.
