Introduction
Overview
This book presents an introduction to programming interactive computer graphics, with an emphasis on
game development, using real-time shaders with DirectX 9.0c. It teaches the fundamentals of Direct3D and
shader programming, after which the reader will be prepared to go on and learn more advanced techniques.
The book is divided into three main parts. Part I explains the mathematical tools that will be used throughout
this book. Part II shows how to implement elementary 3D techniques, such as defining 3D geometry, lighting,
texturing, alpha blending, and stenciling, using shaders and the HLSL. Part III is largely about applying
Direct3D to implement a variety of interesting techniques and special effects, such as working with meshes,
character animation, terrain rendering, picking, particle systems, environment mapping, normal mapping,
and rendering to textures.
For the beginner, this book is best read front to back. The chapters have been organized so that the
difficulty increases progressively with each chapter. In this way, there are no sudden jumps in complexity that
leave the reader lost. In general, for a particular chapter, we will use the techniques and concepts previously
developed. Therefore, it is important that you have mastered the material of a chapter before continuing.
Readers who are experienced Direct3D users can pick the chapters of interest.
Finally, you may be wondering what kinds of games you can develop after reading this book. The answer
to that question is best obtained by skimming through the book and seeing the types of applications that are
developed. From that you should be able to visualize the types of games that can be developed based on the
techniques taught in this book and some of your own ingenuity.
