RECIPE• Mac and OS X 10.6 or later• Kinect• Driver for Mac• Xcode• openFrameworks

DRIVER FOR PC• libfreenect • First Kinect driver for PCs • Simple and Fast.• OpenNI • PrimeSense ofﬁcially released. • Can detect bones

XCODE• For compiling openFrameworks projects.• Bundles many useful development tools. • Compilers (gcc) • Mac OS X Software development kit.

HOMEBREW• Homebrew (a.k.a. brew) is Package manager for OS X• Easiest way to install missing Unix tools. •$ brew install opencv• Require compiler. (provided by Xcode)

OPENFRAMEWORKS• Written by C++• Insanely fast!• Flexible API. Processing like. (setup, update, draw)• Many addons (OpenCV, OSC etc...)• Exists library for Kinect. • ofxKinect, ofxOpenNI

INSTALLATION• Download Xcode installer from Mac App Store

INSTALLATION• Install Homebrew• Google: homebrew install

INSTALLATION• Install libfreenect, libusb-freenect by Homebrew • cd `brew --preﬁx`/Library/Formula •$ curl --insecure -O "https://raw.github.com/OpenKinect/ libfreenect/master/platform/osx/homebrew/libfreenect.rb" •$ curl --insecure -O "https://raw.github.com/OpenKinect/ libfreenect/master/platform/osx/homebrew/libusb- freenect.rb" •$ brew install libfreenect

INSTALLATION• Download openFrameworks v007• http://openframeworks.cc•

INSTALLATION• Put openFrameworks to your home directory• /Users/anyone/of_preRelease_v007_osx

INSTALLATION• Download ofxOpenNI (includes OpenNI Libraries)• Google: ofxopenni• https://github.com/gameoverhack/ofxOpenNI

INSTALLATION• Rename gameoverhack-ofxOpenNI-xxxx to ofxOpenNI• Put ofxOpenNI to openFrameworks addons directory

INSTALLATION• Make application directory • of_preRelease_v007_osx/apps/myapps• Move example project to application directory • of_preRelease_v007_osx/addons/ofxOpenNI/example/ openNI-demoAllFeatures • of_preRelease_v007_osx/apps/myapps/openNI- demoAllFeatures

INSTALLATION• Copy libraries to project folder • src: of_preRelease_v007_osx/addons/ofxOpenNI/mac/ copy_to_data_openni_path/lib • dest: of_preRelease_v007_osx/apps/myapps/openNI- demoAllFeatures/bin/data/openni

OPEN PROJECT• Open Xcode Projet ﬁle • of_preRelease_v007_osx/apps/myapps/openNI- demoAllFeatures/openNiSample007.xcodeproj

DON’T FORGET!!• Switch compiler Apple LLVM compiler to LLVM GCC • Apple LLVM compiler cannot build openFrameworks project• Set deployment target to Mac OS X 10.6 • 10.7 cannot build for Mac OS X SDK reason

RUN AND ENJOY!
