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 the Microsoft Kinect SDK

For using Kinect on Windows 7 and Windows 8, you need to install the Microsoft Kinect SDK. This SDK lets OpenNI access Kinect for Windows and Kinect for Xbox devices.

How to do it...

  1. Open your browser and navigate to

  2. Download the Kinect SDK by clicking on the center-left button named DOWNLOAD LATEST SDK.


    Please note that the current version of OpenNI (OpenNI 2.2) works only with Version 1.6 and higher of Microsoft Kinect SDK. The current stable version of Kinect SDK is 1.7.

  3. Open the installer package after it's downloaded, read and accept the license arguments, and click on the Install button.


    Please note that Microsoft Kinect SDK can only be installed on Windows 7 and later.

  4. Wait for the installation process to complete. At the end of the installation, click on Close and you are done.

How to do it...

Just as with the previous two recipes, we did nothing worth explaining except for downloading and installing the Kinect SDK, Kinect Drivers, and the Kinect Runtime.
