Getting Started Interactive Projection Floor

heya, so the reason for the circle is just so that you can see the coordinates doing their thing. so do you have an oF project using ofxKinect? That'd be the first step, with that then you should be able to then use function calls to ofxKinect to get the data.
My advice would be to have a go at some of the ofxKinect examples and get a feel of it and then go from there
