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.

In this chapter, you expanded on the AR gallery project we began in Chapter 6, Gallery: Building an AR App. That project left us with the ability to place framed photos on our walls. In this chapter, you added the ability to edit virtual objects in the scene.

You implemented the ability to select an existing virtual object in Main-mode, where the selected object is highlighted and the app goes into EditPicture-mode. Here, there is an edit menu with buttons for Replace Image, Replace Frame, Remove Picture, and Done (return to Main-mode). The Replace Image feature displayed the same SelectImage modal menu that is used when we're creating (adding) new pictures. We had to refactor the code to make it reusable.

While placing and moving a picture on the wall, you implemented a feature to avoid overlapping or colliding objects, automatically moving the picture away from the other ones. After that, you implemented some direct interactions with the virtual objects by using...
