Augmented Reality for Android Application Development

Overview of this book

Augmented Reality offers the magical effect of blending the physical world with the virtual world, which brings applications from your screen into your hands. AR redefines advertising and gaming, as well as education. It will soon become a technology that will have to be mastered as a necessity by mobile application developers. Augmented Reality for Android Application Development enables you to implement sensor-based and computer vision-based AR applications on Android devices. You will learn about the theoretical foundations and practical details of implemented AR applications, and you will be provided with hands-on examples that will enable you to quickly develop and deploy novel AR applications on your own. Augmented Reality for Android Application Development will help you learn the basics of developing mobile AR browsers, how to integrate and animate 3D objects easily with the JMonkeyEngine, how to unleash the power of computer vision-based AR using the Vuforia AR SDK, and will teach you about popular interaction metaphors. You will get comprehensive knowledge of how to implement a wide variety of AR apps using hands-on examples. This book will make you aware of how to use the AR engine, Android layout, and overlays, and how to use ARToolkit. Finally, you will be able to apply this knowledge to make a stunning AR application.

Summary


In this chapter you got an introduction to the world of Android camera access and how to display camera images in the JME 3D rendering engine. You learned about various camera parameters and the compromises you have made (for example, between image size and frames per second) to get an efficient camera access. We also introduced the simplest way of displaying a camera view in an Android activity, but also explained why you need to go beyond this simple example to integrate the camera view and 3D graphics in a single application. Finally, we helped you through the implementation of a JME application, which renders the camera background. The knowledge you gained in this chapter is the beneficial basis to overlay the first 3D objects on the camera view—a topic we will discuss in the next chapter.
