Our next task is to install the SimpleOpenNI library. This library enables us to use the OpenNI API in Processing. At first, we will learn how to access and display the depth image of the Kinect controller. Then, we will use the user tracking capabilities of the SimpleOpenNI framework and define some callback functions to get notified when a user is detected or when the tracked user disappears. And finally, we will color all the pixels in the depth image that belong to the user to enable the user to see what is being tracked.

Engage Thrusters

Let's teach Processing how to see:

At the time of writing, the SimpleOpenNI framework could not be installed using the new Library Manager. To install it manually, download the SimpleOpenNI package for your operating system from http://code.google.com/p/simple-openni/downloads/list.

Nikolaus Gradwohl

Nikolaus Gradwohl

Nikolaus Gradwohl was born in 1976 in Vienna, Austria, and always wanted to become an inventor like Gyro Gearloose. When he got his first Atari, he decide that becoming a computer programmer was the closest he could get to that dream. He has since made a living writing programs for nearly anything that can be programmed, ranging from an 8-bit microcontroller to mainframes. In his free time, he likes gaining knowledge on programming languages and operating systems. Nikolaus has been using Processing since 2008, and has written countless sketches and some Processing libraries. You can see some of his work on his blog at http://www.local-guru.net/.
