Recommended reading: Shadows are hardly covered in the textbook (although you find some information on shadow maps and soft shadows in chapter 11.8 and 10.11.2, respectively). The stencil buffer tutorial is recommended background reading (but try to focus on principles, and not on details/code, and don't worry if you don't understand it completely. Browse, don't memorize, the 50 pages). It also covers fake shadows in section 4 and 5 and contains little info on soft shadows in section 6.4.

Exercises: Tutorial 9, problem 4 (Radiosity) [ exercises ]
Recommended reading: Radiosity is hardly covered in the textbook, but the lecture notes and website given above should be enough to understand the basic concepts. In addition, you can browse the Education Slide Set provided on the SIGGRAPH server.

Exercises: Tutorial 9, problems 1-3 (Clipping) [ exercises ]
Recommended reading: Chapter 12 in the textbook. The Sutherland-Hodgman and the Weiler-Atherton algorithm are not covered in the book, but the lecture notes should be sufficient to understand them.

Exercises: Tutorial 8 (texture mapping) [ exercises ]
Recommended reading: This lecture is covered by chapter 11 of the book. The tutorial on "Teaching Texture Mapping Visually" (PDF, HTML) by Rosalee Wolfe from DePaul University contains some nice illustrations of different approaches. Not all of this is covered in the lecture, but the images might help understanding some of the techniques we discussed.

Exercises: Tutorial 6, problem 1 (Hidden Surface Elimination) [ exercises ]
Recommended reading: This lecture is covered by Chapter 8 (Hidden Surface Elimination) in the textbook.

Exercises: see Tutorial 6 from lecture 7, problems 2-6 [ exercises ]
Recommended reading: In the lecture, we addressed only polygone and triangle rasterization and used a different approach than covered in the book. Nevertheless, it doesn't hurt to browse chapter 3.5 (line drawing) and 3.6 (triangle rasterization). The latter one also contains a little bit of information about Gouraud shading. Linear interpolation is covered in chapter 2.10, diffuse shading and phong shading are discussed in chapter 9.1 and 9.2, respectively.

Exercises: Tutorial 7, problems 1-6 (Ray tracing) [ exercises ]
Recommended reading: This lecture basically completes some "loose ends" about Ray Tracing that haven't been covered in the lecture so far, in particular: Ray/triangle intersection (book, section 2.11 and 10.3.2), refraction (book, section 10.7), instancing (book, section 10.8), constructive solid geometry (book, section 10.10), faster ray tracing (book, section 10.9).
