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.

Configuring a new AR scene for face tracking

There are a few simple steps required to configure an AR Foundation-based scene for face tracking. Since we're going to do selfies, we'll set up the AR camera to use input from the front-facing camera. Then we'll add an AR Face Manager component to the AR Session Origin. If you want to use the Unity Onboarding UX animated graphic to prompt the user, you can adapt the ScanMode script for that.

Let's get started!

Setting the AR camera for selfies

Use the following steps to set up the AR camera for selfies:

  1. In the Hierarchy, unfold the AR Session Origin game object and select its child Main Camera.
  2. In the Inspector, set AR Camera Manager | Facing Direction to User.
  3. We also need to set the AR Session tracking mode for rotation only. Select the AR Session game object in the Hierarchy.
  4. In the Inspector, set the AR Session | Tracking Mode to Rotation Only.

Next, we'll add the AR Face...
