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.

Chapter 5. Real-World Motion Tracking

Now that we have all the fun stuff set up and ready to go, we can begin building some real-world AR apps. In order to do this, we will be picking and choosing various pieces we need from the samples. The samples are great examples, but, for the most part, they are nothing more than boilerplate code. This means that we have no reason to rewrite code sections that already work well. Instead, we will focus on adding new code to tackle AR problems. In this chapter, we will dive in and learn in depth how ARCore motion tracking works. We will learn the current limitations of motion tracking with ARCore and develop a technique for overcoming those limitations. Here are the main topics that we will cover in this chapter:

  • Motion tracking in depth
  • 3D sound
  • Resonance Audio
  • A tracking service with Firebase
  • Visualize tracked motion

In order to successfully complete the exercises in this chapter, the reader will need to complete the setup till Chapter 4, ARCore on the Web...
