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.

Testing it out

Now is a good time to Build And Run the scene to make sure things are working as expected so far. Perform the following steps:

  1. First, be sure to save your work by using File | Save.
  2. Select File | Build Settings to open the Build Settings window.
  3. Click Add Open Scenes to add the ARFramework scene to Scenes In Build, and ensure it is the only scene in the list with a checkmark.
  4. Ensure that your target device is plugged into a USB port and that it is ready.
  5. Click Build And Run to build the project.

Once the project builds without errors and launches on your device in Startup mode. You'll first see the words Initializing… from the Startup UI panel.

Once the AR Session is started, the app transitions to Scan mode and you will see the words Scanning... Please move device slowly.

Once a horizontal plane is being tracked, Scan mode transitions to Main mode. You will then see on the screen the words Main Mode Running....
