I’m a code janitor!

So you want to play with the kinect right now

First off, the kinect code here is in such a massive amount of flux as to like, totally not even be funny. You are so amazingly on your own right now, but feel free to hit the #openkinect IRC channel on Freenode for questions.

Building with CMake

To use CMake:

• Make a directory somewhere. Like, say, c/build in your repo directory.

• Go into that directory

• Type cmake ..

• Watch the magic happen

• After this, just run make and you’ll be fine.

• If you want to use an IDE or whatever, well, you’ll figure it out.

Linux

Should "just work" if you have libusb installed. Since there’s no udev rules yet, you’ll need to run as root. Deal with it.

OS X

You will need to pull the libusb-1.0 repo head and patch using the files in platform/osx/. Just go to the root directory of the cloned libusb-1.0 repo and run

patch -p0 < [path_to_OpenKinectRepo]/platform/osx/libusb-osx-kinect.diff

Recompile libusb and put it wherever CMake will look (/usr/local/lib, /usr/lib, etc…​). If you’re using a package manager like fink, macports, or homebrew, I’m going to expect you know what your doing and can deal with this. If not, see IRC channel.

Windows

We’re still working on that.

And everyone else…​

Below is the readmes of the other repos I’m organizing this from. This currently consists of:

• Marcan’s original libfreenect repo (in the c directory here) - GPL’d.

• ofTheo’s OS X libfreenect patched (integrated by me, with libusb-1.0 patches in platform directory) - GPL’d

• JoshBlake’s C# OpenKinect (in the csharp directory, with inf files in platform directory) - Apache’d

The aggregated READMEs are below.

Marcan’s Readme

Horribly hacky first take at a Kinect Camera driver. Does RGB and Depth.

main.c implements a simple OpenGL visualization. Hopefully it should be mostly self-explanatory…​ You pretty much just open the USB device, call cams_init(dev, depthimg, rgbimg), and your depthimg and rgbimg callbacks get called as libusb processes events.

TODO:

• TONS of cleanup. I mean LOTS.

• Determine exactly what the inits do

• Bayer to RGB conversion that doesn’t suck

• Integrate support for the servo and accelerometer (which have already been reverse engineered)

BIG TODO: audio. The audio chip (the Marvell) requires firmware and more init and does a TON of stuff including the crypto authentication to prove that it is an original Kinect and not a clone. Who knows what this thing does to the incoming audio. This should be interesting to look at.
