Advanced Lighting Models
The classic lighting model lacks some realism. To generate more realistic images, we need to have more realistic models for illumination, shadows, and reflection than those we’ve discussed so far. In this section, we explore how OpenGL Shading Language can help us implement some of these models. Much has been written on the topic of lighting in computer graphics. We examine only a few methods now. Ideally, you’ll be inspired to try implementing some others on your own.
