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.

Expanding the project with multiple planets

To add another planet to the project, we need to add its planet card image to the Reference Image Library, create its planet prefab, including a material for rendering the planet skin, and add the reference to the planetPrefabs list in PlanetsMainMode. Then, we'll update the script to handle tracking multiple planets. Let's walk through the steps for adding Mars.

Adding the planet card image to the Reference Image Library

Perform the following steps to add Mars to our Reference Image Library:

  1. Locate and select your ReferenceImgeLibrary asset in the Project window. (If you've been following along, then it should be located in the Image Library/ folder.)
  2. In its Inspector window, click Add Image.
  3. Locate and drag the Mars-MarkerCard image from the Project window and drop it onto the empty image Texture slot in the Inspector window.
  4. Check the Specify Size checkbox and enter the same Physical Size | X value...
