During this unit we will be covering a lot of topics ranging from lighting within our 3D graphics scene to shading, textures, and bump and normal maps. All of these topics are related in that all of them use the properties of illumination (lighting) to create effects. As part of your discussion responses you must discuss the role of lighting in shading and bump and normal maps. In particular your discussion should address how bump and normal maps use light and shadow to create the illusion of texture.
