It also lists the forms of the transformation matrices used for rotation, scaling, translation, perspective projection, and orthographic projection. These topics are introduced and discussed in Chapter 3. For a more detailed discussion of these subjects, see almost any book on three-dimensional computer graphics—for example, Computer Graphics: Principles and Practice, by Foley, van Dam, Feiner, and Hughes (Addison-Wesley, 1990); or a text on projective geometry—for example, The Real Projective Plane, by H.
