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.

Performing a Building and Run

To build and run the project, use the following steps:

  1. Open the Build Settings window using File | Build Settings.
  2. Click the Add Open Scenes button if the current scene (FrameworkDemo) is not already in the Scenes In Build list.
  3. Ensure that the FrameworkDemo scene is the only one checked in the Scenes In Build list.
  4. Click Build And Run to build the project.

When the project builds successfully, it starts up in Startup-mode while the AR Session is initializing. Then it goes into Scan-mode that prompts the user to scan the environment, until at least one horizontal plane is detected and tracked. Then it goes into Main-mode and displays the main menu. Screen captures of the app running on my phone in each of these modes are shown in the following figure:
