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.

Tips for managing better performance


Now that we have a grasp on how to profile our apps, let's take a look at the primary items that will impact performance. The order of these items is ordered by general importance, but the individual requirements of your app may alter these priorities. Feel free to consult the following checklist the next time you need or want to profile your app:

  • Rendering (includes all CPU and memory resources responsible for rendering a frame):
    • Render loop (CPU performance): Check the timing of the render function and watch for any expensive calls. Ensure that you minimize any object instantiation, logging, or inner loops. Remember that the render function, typically called Update, will be called 30 times per second or more. All the tools we looked at will let you perform this vital task.
    • Frame rate (render time): Outside of optimizing your code, the frame rate will often be dictated by the complexity and number of objects we are rendering. As such, you may want to go...
