OpenNI Cookbook

Overview of this book

The release of Microsoft Kinect, then PrimeSense Sensor, and Asus Xtion opened new doors for developers to interact with users, re-design their application’s UI, and make them environment (context) aware. For this purpose, developers need a good framework which provides a complete application programming interface (API), and OpenNI is the first choice in this field. This book introduces the new version of OpenNI. "OpenNI Cookbook" will show you how to start developing a Natural Interaction UI for your applications or games with high level APIs and at the same time access RAW data from different sensors of different hardware supported by OpenNI using low level APIs. It also deals with expanding OpenNI by writing new modules and expanding applications using different OpenNI compatible middleware, including NITE. "OpenNI Cookbook" favors practical examples over plain theory, giving you a more hands-on experience to help you learn. OpenNI Cookbook starts with information about installing devices and retrieving RAW data from them, and then shows how to use this data in applications. You will learn how to access a device or how to read data from it and show them using OpenGL, or use middleware (especially NITE) to track and recognize users, hands, and guess the skeleton of a person in front of a device, all through examples.You also learn about more advanced aspects such as how to write a simple module or middleware for OpenNI itself. "OpenNI Cookbook" shows you how to start and experiment with both NIUI designs and OpenNI itself using examples.

Downloading and installing OpenNI

The first step to use OpenNI to develop any application or game is to install the OpenNI framework on your development machine. In this recipe, we will show you how to install OpenNI; actually it is as easy as 1-2-3.

How to do it...

  1. Open your browser and navigate to The following screen will be displayed:

  2. Download the latest version of OpenNI for your platform and CPU architecture. We recommend downloading both 32-bit (x86) and 64-bit versions of OpenNI if you are using a 64-bit OS.

  3. Open the downloaded file; it is usually a ZIP file that can be opened by different programs (including but not limited to WinZip, WinRar, 7Zip, and so on) and even Windows Explorer. Then run/open the OpenNI installer from within the zipped archive:

  4. Click on Install in the installer dialog:

  5. Wait for the installation process to complete. If any dialog appears to ask for an approval of drivers during the installation process, simply click on the Install button:

  6. At the end of the installation, click on Finish and you are done.

How it works...

There is nothing special here; we downloaded and opened the archive file and then executed the installer package. Also, we accepted the installation of new drivers to the Windows catalog.
