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.

Making dynamic face meshes with a variety of materials

To show an augmented face that matches your real-life expressions, Unity AR Foundation lets you generate a face mesh dynamically at runtime. On this mesh, you can apply different materials, giving the effect of you wearing arbitrary face masks. To add this to our project, we'll first look at the default face game object given by AR Foundation. Then we'll create several different materials to use. To integrate this feature into our project, we'll extend the ChangeableFace script to switch materials, add a similar function to the FaceMainMode script to update the face trackables, and then add menu buttons to switch materials.

Exploring AR Default Face

You can create a dynamic face game object for AR Foundation from the Unity menu at GameObject | XR | AR Default Face. The object includes an AR Face Mesh Visualizer component that generates a face mesh at runtime that matches your facial expressions, including moving...
