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.

Attaching stickers to face regions (ARCore)

If your project is using ARCore XR Plugin and Android, you have access to ARCore-specific features, including transforms for three important face regions: the nose tip, left forehead, and right forehead. If you raise your left eyebrow, for example, that transform will move independently of the rest of the face, providing some more detail to the facial expressions in your app.

In addition to what we do here, you may also want to look at the ARCoreFaceRegions scene in the AR Foundation Samples project (see the ARF-samples/ folder in your project), and the ARCoreFaceRegionManager script it uses. The code we develop in this section is considerably simpler and easier to follow.

To demonstrate ARCore face regions, we'll implement several 2D stickers and attach them to the 3D face regions. We'll let you add eyebrows, a mustache, and licking lips using clipart that we identified at the top of this chapter (and I edited in Photoshop...
