Learn ARCore - Fundamentals of Google ARCore

Overview of this book

Are you a mobile developer or web developer who wants to create immersive and cool Augmented Reality apps with the latest Google ARCore platform? If so, this book will help you jump right into developing with ARCore and will help you create a step by step AR app easily. This book will teach you how to implement the core features of ARCore starting from the fundamentals of 3D rendering to more advanced concepts such as lighting, shaders, Machine Learning, and others. We’ll begin with the basics of building a project on three platforms: web, Android, and Unity. Next, we’ll go through the ARCore concepts of motion tracking, environmental understanding, and light estimation. For each core concept, you’ll work on a practical project to use and extend the ARCore feature, from learning the basics of 3D rendering and lighting to exploring more advanced concepts. You’ll write custom shaders to light virtual objects in AR, then build a neural network to recognize the environment and explore even grander applications by using ARCore in mixed reality. At the end of the book, you’ll see how to implement motion tracking and environment learning, create animations and sounds, generate virtual characters, and simulate them on your screen.

Navigating the map


In a traditional AR app, you rarely move the user or player. The user or player move themselves, and the AR app works around that. We spent a good portion of this book understanding how ARCore tracks the user and understands their environment, which has worked quite well when working with small objects such as Andy. Except, if we want to render massive virtual objects or even embed new environments, then we need a way for the user to navigate those as well. Therefore, in this section, we will look to implement a mix of navigation methods from a standard touch interface to AR and MR versions. If you don't have a HoloKit or are not interested in trying MR, then you can stick to just working with the AR.

Before adding navigation to our app, we probably should look at how navigation is handled by default in WRLD. Open up the Unity editor and follow along:

  1. Save your current scene.
  2. Create a new scene. Name it Navigation and save the scene in the Assets/HoloCore/Scenes folder.
  3. From...
