first, download the zip file on this page by clicking the 'download' button at the top right.

then download the zip file on https://github.com/ofTheo/ofxKinect.

unzip ofxKinect and rename the unzipped folder to ofxKinect.

move ofxKinect to your addons/ folder.

ofxControlPanel is distributed with the DepthVisualizer, so you don't need to download it separately. if you need it in the future, you can find it at https://github.com/ofTheo/ofxControlPanel/

if you would like to run with test data instead of using a kinect, there is a short 8 MB download available at http://kylemcdonald.net/3dsav/janus-1283433262.zip be sure to place the unzipped directory in your data directory:

DepthVisualizer/bin/data/janus-1283433262

if you change the variable 'useKinect' at the top of testApp.cpp to 'false', the testApp will try and load the janus-1283433262 animation.

the animation is stored as a sequence of RGBA PNGs, where the alpha encodes depth information.

recording from the kinect into this format is left as an 'exercise for the reader' at the moment ;)
