Unity Virtual Reality Projects - Second Edition

By: Jonathan Linowes

Overview of this book

Unity has become the leading platform for building virtual reality games, applications, and experiences for this new generation of consumer VR devices. Unity Virtual Reality Projects walks you through a series of hands-on tutorials and in-depth discussions on using the Unity game engine to develop VR applications. With its practical and project-based approach, this book will get you up to speed with the specifics of VR development in Unity. You will learn how to use Unity to develop VR applications that can be experienced with devices such as Oculus, Daydream, and Vive. Among the many topics and projects, you will explore gaze-based versus hand-controller input, world space UI canvases, locomotion and teleportation, software design patterns, 360-degree media, timeline animation, and multiplayer networking. You will learn about the Unity 3D game engine via the interactive Unity Editor, and you will also learn about C# programming. By the end of the book, you will be fully equipped to develop rich, interactive VR experiences using Unity.

Virtually Everything for Everyone

This virtual reality thing calls into question, what does it mean to
"be somewhere"?
Before cell phones, you would call someone and it would make no sense to
say, "Hey, where are you?" You know where they are, you called their house,
that's where they are.
So then cell phones come around and you start to hear people say, "Hello. Oh, I'm at Starbucks," because the person on the other end wouldn't necessarily know where you are, because you became un-tethered from your house for voice communications.
So when I saw a VR demo, I had this vision of coming home and my wife has got the kids settled down, she has a couple minutes to herself, and she's on the couch wearing goggles on her face. I come over and tap her on the shoulder, and I'm like, "Hey, where are you?"
It's super weird. The person's sitting right in front of you, but you don't know where they are.

Welcome to virtual reality (VR)! In this book, we will explore what it takes to create virtual reality experiences on our own. We will take a walk through a series of hands-on projects, step-by-step tutorials, and in-depth discussions using the Unity 3D game engine and other free or open source software. Though the virtual reality technology is rapidly advancing, we'll try to capture the basic principles and techniques that you can use to make your VR games and applications feel immersive and comfortable.

In this first chapter, we will define virtual reality and illustrate how it can be applied not only to games but also many other areas of interest and productivity. This chapter discusses the following topics:

  • What is virtual reality?
  • Differences between virtual reality and augmented reality
  • How VR applications may differ from VR games
  • Types of VR experiences
  • Technical skills that are necessary for the development of VR
