Discussion Prompt:

We will be covering a lot of topics ranging from lighting within our $3$D graphics scene to shading, textures, and bump and normal maps during this unit. All of these topics are related because all of them use the properties of illumination $($lighting$)$ to create effects.

$*$ Discuss the role of lighting in shading and bump and normal maps.

$*$ Explain how bump and normal maps use light and shadow to create the illusion of texture.
