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.

Getting started

To begin, we'll create a new scene named FaceMaker using the ARFramework scene template. If you're targeting iOS ARKit, there may be additional setup required, including installing the separate ARKit Face Tracking package. Then we'll add a project title to the UI before moving on to adding face tracking to the scene.

Creating a new scene using the ARFramework template

Create a new scene in your Unity AR-ready project using the following steps:

  1. Select File | New Scene.
  2. In the New Scene dialog box, select the ARFramework template.
  3. Click Create.
  4. Select File | Save As. Navigate to the Scenes/ folder in your project Assets folder, give it the name FaceMaker, and click Save.

The new AR scene already has the following setup from the template:

  • AR Session game object with an AR Session component.
  • An AR Session Origin rig with an AR Session Origin component, among others, and a child main camera. We will replace its...
