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 2: Your First AR Scene

Creating a simple Augmented Reality (AR) scene is quite simple with Unity AR Foundation. The steps involved might only take a page or two. However, when we create a scene together in this chapter, each step will be explained in context so that you can gain a full understanding of what comprises an AR scene using AR Foundation.

But before we do that, we'll take a look at some AR examples provided by Unity, including the AR Foundation Samples project, and build their example scenes for your device. And because that project contains some useful assets, we'll export those as an asset package for reuse in our own projects.

In this chapter, we will cover the following topics:

  • Building and running the AR Foundation Samples project
  • Exporting and importing sample assets
  • Constructing a new Unity AR scene
  • Introduction to C# programming and the MonoBehaviour class
  • Using AR raycast to place an object on a plane
  • Instantiating...
