The authors have generously provided us with an optimal blend of concepts and philosophy, illustrative figures to clarify the more difficult points, and source code fragments to make the ideas concrete. Of particular interest is the chapter on multithreaded rendering, a topic that is essential in a multicore world. Later chapters include many examples such as skinning and displacement, dynamic tessellation, image processing (to illustrate DirectCompute), deferred rendering, physics simulations, and multithreaded paraboloid mapping. As if all this is not enough, the authors have made available their source code, called Hieroglyph 3. Books do not get any better than this!
