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.

Summary


With that, we complete our look at motion tracking with ARCore. As we learned, ARCore gives us the ability to track position and rotation or the pose of a device using feature identification correlated with the device's motion sensors. We then learned why it is important to track the position of a user when building AR apps with 3D sound. This taught us the difference between our audio and virtual (3D) scene and how to convert between references. We then extended our ability to track a user by setting up a Firebase Realtime Database and connected that to our AR app. By doing this, we could now track a single user or multiple users globally. Of course, we didn't have enough time here to build on this further. For now, we finished the app by drawing the user's travel path while the device moves around an area.

In the next chapter, we will jump back to working with Android (Java) and learn more about environmental understanding and various related 3D concepts, which is the next topic...
