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.

Interacting with the virtual


We want our users to be able to place and then move or adjust their object's pose as they need to. If you recall, a pose represents the six degrees of freedom that an object can be represented in in 3D space. Before we start posing an object though, we need to be able to select an object. After we select an object, we want to be able to outline it in order to identify it to the user as selected. Since outlining the object sounds like an essential first step, let's tackle that first. Follow along the given steps to create the object outlining:

  1. Go back to Unity. Create a new folder in the Assets/ARCoreDesign/Materials folder and name it Shaders.
  2. Right-click (Ctrl + Click on Mac) inside the new folder within the Project window and from the Context menu, select Create | Shader | Standard Surface Shader. Name the new shader ARMobileSpecularOutline.
  3. Double-click on the ARMobileSpecularOutline shader to open it in your code editor.
  4. Delete the contents of the file. We will...
