this used to be a fork from https://github.com/gameoverhack/ofxOpenNI/
The ofxOpenNI module is a wrapper for the openNI + NITE + SensorKinect libraries/middleware. Currently is still in pre-beta and only works/tested this on Mac.
Go to your addons directory, and follow these commands
git clone https://github.com/roxlu/ofxOpenNI.git cd ofxOpenNI git checkout experimental
