I must agree with J. Davis. After going through about 3-4 different types of CG courses and experimenting with my own seminars I find that this book is just way too wide of a scope. It seems like it tries to cram general computer graphics, interactive computer graphics, and advanced computer graphics in one... and do a bad job at it. Looking through the book I seriously doubt that some topics can be covered in one chapter, especially some of the viewing chapters. How can you cover all aspect of 2D and 3D viewing, even in breadth only and no depth, in one chapter? That's just ridiculous. It almost feels as if they are saying that you need a separate major for CG completely, one course for overview, one for 2d, one for 3d, one for interactive graphics, and a few for advanced topics in computer graphics... but the problem is that that is too narrow of a scope for any 4 year college degree. Plus you can't even start some of the basic discussions without general education in the fundamental math like linear algebra, calculus, discrete math, and so forth. So this book is sort of making a statement that can't be backed in the real world. Though this does offer a good overview for people who are just curious. It touches on a wide variety of things and has very practical approach to having a workable project using openGL.
Now as for Davis's comments on a good book. I think Foley and van Dam has actually a pretty good book for undergrads, especially when you set appropriate prequisits for the course. Keeping in mind that CG should be a junior-senior level undergrad course. I studied CG1 when I was an art major and found the Foley van Dam book to usable, though dry, but usable. I found other books later on to be useful, but they are a bit specialized. A few good ones I must suggest for graphics math is essential mathematics for games by van verth and bishop to be good. I also recommend realtime graphics by akenine-moller and haine for interactive graphics. For some specialized ones you have to look around but I do recommend my professor's (david breen) book on cloth animation. But yeah, to sum it up, stick with Foley van Dam for your intro courses... maybe use this as an added supplement, especially when considering OpenGL for your teaching tool.
