There are two methods of adding light to your 3D scenes: using computer representations of real lights
(
standard lighting
) or casting light from the environment and textures in the scene (
radiosity
). The former is
relatively easy to compute and delivers results more quickly. The latter uses more-complex computation and
slows the finished image but results in lighting with more subtlety, nuance, and realism.
Figure 1-4
shows a
simple scene with standard lighting, and
Figure 1-5
shows that same scene using radiosity.
