Graphics programming is the magic behind video games, film, and scientific simulation. Every
explosion, dust particle, and lens flare you see on a computer screen is processed through a
graphics card. In addition, because modern operating systems use the graphics processing unit
(GPU) to draw their content, every pixel you see is rendered through the GPU and through
software developed by a graphics programmer. It’s a broad topic, but one that has traditionally
been the province of a select few. Even to experienced software developers, rendering is often
considered a dark art, full of complex mathematics and esoteric tools. Furthermore, the rapid pace
of advancement makes modern graphics programming a moving target, and establishing a
foothold can be difficult.
That’s where this book comes in. In these pages, you’ll find an introduction to real-time 3D rendering. I’ve
presented this material in a straightforward and practical way, but it doesn’t shy away from more complex
topics. Indeed, this book takes you far beyond drawing simple objects to the screen and introduces
intermediate and advanced subjects in modern rendering. It is my sincere wish that you find the material in
this book approachable, applicable, and up-to-date with modern graphics techniques.
