PBODY:
I know you said the code is for processing but I have a book and it said add the samples to the library click on the depth map and boom I should have a screen shot of myself but I didn't get it through arduino I got it threw openni though I am a little lost I don't want to move onto the next step if I dont fully understand this one.
Nothing in this incoherent run-on makes sense.
In the code's comments it says: "Processing Wrapper for the OpenNI/Kinect library".
Visit the web site in the code's comments: Google Code Archive - Long-term storage for Google Code Project Hosting.
This site says: "This project is a simple OpenNI and NITE wrapper for Processing."
I don't care what your book says, you have code meant for Processing. If you double-clicked a file on your computer and the Arduino IDE opened, that's because Arduino IDE and Processing used the same file extension.
You need to get Processing from processing.org.
