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.

Chapter 3. Superimposing the World

Now that you have a view of the physical world on your screen, our next goal is to overlay digital 3D models on top of it. Overlay in 3D as used in Augmented Reality, is different from basic 2D overlays possible with Adobe Photoshop or similar drawing applications (in which we only adjust the position of two 2D layers). The notion of 3D overlay involves the management and rendering of content with six degrees of freedom (translation and rotation in three dimensions) as shown in the following figure:

In this chapter, we will guide you through the different concepts and present you with the best way to superimpose real and virtual content. We will successively describe the concept of real and virtual cameras, how to perform superimposition with our scene graph engine, and create high quality superimposition. First, let's discuss the 3D world and the virtual camera.
