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 NiTE

If you want to use high-level outputs and some advanced tracking and recognition features of NiTE, you need to install it as well. NiTE is a middleware based on the OpenNI framework and needs to be installed after it.

Getting ready

Before installing NiTE, you need to have OpenNI installed using the Downloading and installing OpenNI recipe in this chapter.

How to do it...

  1. Before downloading NiTE, you need to register yourself in For doing so, please open your browser and navigate to Now fill all the fields and click on the Submit button:

  2. After the registration, if everything goes fine, you'll be able to download NiTE. Open your browser and navigate to

  3. Download NiTE using the big DOWNLOAD button at the upper-right corner and then select your desired version of it:

  4. 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 actual installer from within the zipped archive:

  5. Read and accept the license arguments, then click on Next and then on Install in the installer dialog:

  6. Wait for the installation to complete and, at the end of the installation, click on Finish and you are done:

How it works...

Actually we did nothing special here either; all we did was register, download, and install NiTE for our version of the OS and CPU architecture.
