Overview of this book

Augmented reality applications allow people to interact meaningfully with the real world through digitally enhanced content. The book starts by helping you set up for AR development, installing the Unity 3D game engine, required packages, and other tools to develop for Android (ARCore) and/or iOS (ARKit) mobile devices. Then we jump right into the building and running AR scenes, learning about AR Foundation components, other Unity features, C# coding, troubleshooting, and testing. We create a framework for building AR applications that manages user interaction modes, user interface panels, and AR onboarding graphics that you will save as a template for reuse in other projects in this book. Using this framework, you will build multiple projects, starting with a virtual photo gallery that lets you place your favorite framed photos on your real-world walls, and interactively edit these virtual objects. Other projects include an educational image tracking app for exploring the solar system, and a fun selfie app to put masks and accessories on your face. The book provides practical advice and best practices that will have you up and running quickly. By the end of this AR book, you will be able to build your own AR applications, engaging your users in new and innovative ways.

Chapter 1: Setting Up for AR Development

Augmented reality (AR) is widely recognized as the next-generation computing platform where digital content is seamlessly merged into real-world experiences. This book will help get you started with developing your own AR applications using the Unity 3D game engine and the AR Foundation toolkit provided by Unity.

In this chapter, you will take your first steps by setting up your computer for AR development using the Unity 3D game engine. We will begin by briefly defining augmented reality, thus setting the context for this industry and some of the basics of AR technology. We will then install the Unity software, the AR Foundation toolkit, and make sure your system has been set up to develop for Android and/or iOS mobile devices. Finally, we'll build and run a test scene to verify things are working as they should.

We will cover the following topics:

  • Defining augmented reality
  • Getting started with Unity, including installation and using Unity
  • Preparing your project for AR development, including XR plugins, AR Foundation, Input System, and the Universal Render Pipeline
  • Setting up for mobile development (Android ARCore and iOS ARKit)

    Note for Experienced Readers

    If you are already familiar with Unity, already have it installed on your system, and are set up to build for your iOS or Android mobile device, you may be able to skim through details related to those topics that are interspersed in this chapter.
