INTRODUCTION

WELCOME TO Game and Graphics Programming for iOS and Android with OpenGL ES 2.0 . This book is not your usual OpenGL Hello Triangle book its not meant to explain the why (Google is there for that), but rather, to show you the how. This book will strictly teach you what works and what doesnt when it comes to game and graphics programming.

Using more than 50 unique tutorials (which also include some full game frameworks), this book adopts a straightforward practical approach (probably never seen before) that only focuses on what you need to learn to insure that you will be able to create a game.

You will learn all the necessary elements in order to create a full-fledged game with rich 3D graphics. If you are looking for an aggressive teaching method that enables you to quickly move forward to create your dream game, this book is for you!

WHO THIS BOOK IS FOR

Be aware that this is not a beginner book. It is an intermediate-level book that assumes you are familiar with linear algebra (matrices, vectors, and quaternions), you have a strong C/C++ programming background, you have at least touched base with OpenGL or OpenGL ES, and you basically know how computer graphics work in general.

If you have this necessary knowledge, and want to make lightning-fast progress in game and graphics programming, then you have found the right publication. This book is written for people who want to learn the hardcore stuff fast in order to be able to create and push a full-fledged game on the App Store and the Android Market.

WHAT THIS BOOK COVERS

Basically everything you need to know in order to create a full game is included in this book. You will learn about all aspects of creating a game, such as loading 3D geometries and textures; how to handle materials, shaders, sounds, cameras, clipping, physics, AI, pathfinding, skeletal animations; and a lot more.

By the end of this book you will be able to apply the knowledge youve learned and combine the different tutorials youve completed to create your own state-of-the-art game.

HOW THIS BOOK IS STRUCTURED

This book is structured in such a way that pretty much all chapters depend on each other. Each chapter shows you progressively how to master the necessary techniques to be able to handle the next chapter.

Here is a list of all the chapters and what will be covered in each of them:

• Chapter 1, Getting Started You will learn how to set up your development environment, download this books SDK, import and re-compile the tutorials, and deal with the template project that you will be using throughout this publication.
• Chapter 2, Setting Up Your Graphic Projections Since you have a running template, I will show you how to set up the necessary projection matrix to be able to handle 2D, 2.5D, or 3D. You will also learn how to draw simple geometry onscreen and handle a camera matrix.
• Chapter 3, Dealing with Complex Geometry You will create a Wavefront OBJ viewer that will allow you to learn how to load complex geometry from disk. You will also learn how to load and create textures, deal with basic lighting, and respond to touch events.
• Chapter 4, Building a Scene This chapter will extend the knowledge that youve learned in Chapter 3 and will explain how to handle a more complex scene. You will learn about drawing sequences and how to create reusable shaders.
• Chapter 5, Optimization In this chapter, I will show you techniques that will allow you to optimize the performance of your drawing. You will touch base with texture compression and shader optimization, and learn how to convert triangles to triangle strips as well as other tips and tricks to get better FPS.
