jit.freenect.grab

What is it? 

jit.freenect.grab is an external object that allows you to grab images and control Microsoft Kinect devices from within Cycling 74’s Max/MSP/Jitter. jit.freenect.grab makes use of the OpenKinect project’s libfreenect library. It is being developed by Jean-Marc Pelletier, Nenad Popov and with help from Andrew Roth.

Features  

  • Retrieve RGB images.
  • Retrieve depth maps.
  • Retrieve images from the infrared camera.
  • Retrieve accelerometer readings.
  • Control the Kinect’s tilt motor.
  • Use multiple Kinects simultaneously. (Depth sensors may interfere with each other.)

Download  

The latest version of jit.freenect.grab is “Release Candidate 5”, which was released on 2012-3-7. The object requires Max 5 with Jitter and only runs on Intel Macs with OS 10.5 or later.

Note: this version is not compatible with the newest Kinects. I unfortunately do not have the time to update the external.

Download jit.freenect.grab release candidate 5 and its help file.

Once you have downloaded the files, you only need to place them in the “Cycling 74” folder inside the “Max 5” Application folder.

jit.freenect.grab is released under the Apache 2.0 license. You can download the source from the main Github repository.

    Hi, sorry, I don’t have any time to dedicate to this project anymore… It’s open source, so if some enterprising soul (wink, wink) wants to have a stab at re-compiling, that would be great.

    Hi! First, must say your tool is amazing! And I must thank you for it! 🙂
    Second, there seems to be a known strange thing happening with the jit.freenect.grab: whenever I use it, or even just open the help file I get in the max window this yellow looking message: float32 bad number.
    Also here in the forum some people pointed it out:

    Any chance to know why? Is this affecting the functionality of the object itself?
    Thanks in advance!

    Hi, I think this might be because you’re using 64-bit Max. I don’t know if this affects functionality.

    Thank you so much for these awesome externals! I have download the ‘latest build from the Github repository’ (updated on 2015.4.30) but the drawing externals (cv.jit.blobs.bounds.draw, cv.jit.blobs.centroids.draw etc) are missing. How can I get these?

jit.freenect.grab Release Candidate 4

A number of people have been writing me about what appeared to be a memory leak in jit.freenect.grab. Indeed, there was. It’s been found, and as far as I can tell, it’s been squashed. If any of you wish to compile the external on your own, please beware that it is the OSX version of […]

jit.freenect.grab Release Candidate 3

Release candidate 3 is out! jit.freenect.grab It’s now possible to output the raw image from the infrared camera instead of the RGB image. This is the raw data the Kinect uses to estimate depth. This means that by blocking the infrared projector (on the left side of the device) it’s now possible to use the […]

jit.freenect.grab Release Candidate 2 is out (finally)

Taking a short break from what has been a truly hectic and near-sleepless month, I found the time to upload a slightly improved jit.freenect.grab. Several users have reported to me that jit.freenect.grab stops working after a while. I think I’ve identified the culprit and this new version may solve the problem. I hope so. jit.freenect.grab […]
