Unity 2018 Augmented Reality Projects

By: Jesse Glover

Overview of this book

Augmented Reality allows for radical innovations in countless areas. It magically blends the physical and virtual worlds, bringing applications from a screen into your hands. Meanwhile, Unity has now become the leading platform to develop augmented reality experiences, as it provides a great pipeline for working with 3D assets. Using a practical and project-based approach, Unity 2018 Augmented Reality Projects educates you about the specifics of augmented reality development in Unity 2018. This book teaches you how to use Unity in order to develop AR applications which can be experienced with devices such as HoloLens and Daydream. You will learn to integrate, animate, and overlay 3D objects on your camera feed, before gradually moving on to implementing sensor-based AR applications. In addition to this, you will explore the technical considerations that are especially important and possibly unique to AR. The projects in the book demonstrate how you can build a variety of AR experiences, whilst also giving insights into C# programming as well as the Unity 3D game engine via the interactive Unity Editor. By the end of the book, you will be equipped to develop rich, interactive augmented reality experiences for a range of AR devices and platforms using Unity.

Code implementation details

Obviously, the most important part of any project is actually to implement what we want to accomplish. We want this project to play a literary quote from a list of audio samples automatically. To do this, we need an audio source and audio clips. We also want this project to take advantage of ARKit to run, so we need to write a C# class that utilizes features from the ARKit plugin that is exposed from the Objective-C and C++ libraries.


Let’s open up the ARHitCube class, fill in the details, and explain what is happening at the same time. I should note that very similar code is already provided in the script file called UnityARHitTestExample; I created this script to be able to show only what is needed and to be able to explain the workflow/thoughts necessary for creating the functionality we need:

using System;
using System.Collections.Generic;
  1. As per usual, we will only call the specific namespaces we need for our project. In this case, it is System and System.Collections...
