    Preface Virtual reality has captured the world’s imagination. Over the last few years, developers and enthusiasts in the thousands have devoted countless hours to coding, designing, and speculating about the possibilities of this exciting new medium. Affordable hardware systems like the Oculus Rift, Samsung Gear VR, and Google Cardboard VR allow consumers to experience virtual reality firsthand in the comfort of their homes, in a cafe, or on the train to work. Press coverage has reached beyond the trade press and blogosphere to mainstream publications extolling the virtues of VR, and the possibilities seem endless: from gaming and cinema to architecture, education, training, and medicine. Even though it has a long way to go, virtual reality appears poised to become the next major entertainment medium, and perhaps even the computing platform of the future. I first tried an Oculus Rift in the summer of 2013. I was, to put it bluntly, underwhelmed. The graphics of the original development kit (the so-called “DK1”) were low-res by today’s standards, and I lasted about 10 minutes before the nausea kicked in — which, according to my friend Dave, was an impressive display of endurance. I put the device aside, grumbled “not ready,” staggered back to work, and didn’t give the matter much thought again until nine months later, when the tech industry was set on its ear by the announcement that social media giant Facebook had acquired Oculus VR, the makers of the Rift. Like many of my peers, I was stunned. Also, like many of my peers, I decided to jump right in and start developing something in VR. Since the watershed Oculus acquisition, the industry has invested millions in developing applications, content, tools, display hardware, video capture systems, and peripherals. Big tech players are already staking out their turf, making bets on what the future will look like with respect to distribution channels, “killer apps,” and such, and creating platforms and ecosystems to align with their visions. Developers of all shapes and sizes are flocking to VR, some out of genuine excitement for a new medium with great potential, and 6
    others preparing to take advantage of what could be the next tech boom after mobile. However it all ultimately shakes out, being a VR developer promises to be an exciting ride. Every journey begins with a first step, and this book is here to set you on your path. It’s not deep; the goal is to familiarize you with core programming concepts, and the innovations in hardware and software that have made VR possible. It is broad: we cover three of the major platforms, using three different development environments and as many programming languages. By the end, you should come away with the feeling that you understand the basics, and a desire to learn more. 7
    Audience This book was written for programmers and designers looking for an introduction to virtual reality development. It assumes at least entry-level programming experience, but you don’t have to be a professional developer to read it. Creative coders, producers with a programming background, and technically savvy artists should also be able to follow along. I want anyone who likes to make things on a computer to be able to walk away having learned something from this book. Readers should know the basics of JavaScript, Java, C#, or another C-family programming language. Experience with 3D graphics is also helpful. If you don’t have 3D experience, Chapter 3 contains a primer that you may find useful. If you are a professional developer, a lot of this material will seem basic to you. But go through it carefully: interleaved with the how-tos and 101s are essential nuggets of technical information for putting together desktop, mobile, and web VR apps. It represents many hours of carefully working through the details of various tools, SDKs, APIs, and operating systems, including suffering through a few major upgrades that were sprung on me halfway through writing the manuscript. Maybe my effort will help save you from hitting those same land mines along the way. If you are a native developer of mobile and desktop apps, and know Unity3D or another game engine, then this book should help you extend your skills into VR. If you are comfortable developing for WebGL, then you should have an easy time creating VR for the Web with the introduction of just a few new concepts. If you are a newbie at both, no worries; I like to think I wrote the book in a way that will get you going, no matter your starting point. 8
