Kinect + Isadora Tutorials Now Available


  • Tech Staff

    Dear Community,

    I'm happy to present to you a three-part series on working with the Kinect using Isadora. These tutorials, written by Montgomery Martin, were based on techniques presented by Mark Coniglio during Troika Ranch’s Live-I Workshop in July 2015_._ They now live on the main TroikaTronix site.

    Over the three part tutorial, we discuss how to use the open-source sketchbook application Processing to act as a communication bridge between the Kinect hardware and Isadora.

    Part 1 serves as an introduction to the Kinect and what it can offer, along with some important points about particular versions of the camera:

    In **Part 2** of this tutorial, we will learn how to download, install, and configure Processing to receive full body motion data and infrared video from an Xbox Kinect motion sensor.

    In Part 3, you will learn how to set up Isadora to receive the OSC and Syphon feeds that Processing broadcasts from the Xbox 360 Kinect camera.

    Thank you especially to the rest of the TroikaTronix team for their valuable feedback and assistance in compiling, reviewing, and editing these tutorials: Mark Coniglio, Jamie Griffiths, and Ryan Webber, Michel Weber and Graham Thorne.

    Cheers, and enjoy!

    Sincerely,

    Monty Martin and

    The TroikaTronix Team



  • Hello,

    I tried to open the tutorial but there is only the top of the text, I tried in safari, firefox and chrome (tacos), and it's the same.

  • If you're on Mac, you can open the link with the right mouse button and then select "Open in New Window".
    Best.

  • it works, thanks



  • Hi and thank you very very much for these tutorials. Well done, great job!

    I have a little question about the last part
    @ http://troikatronix.com/support/kb/kinect-tutorial-part3/
    on "SETTING UP THE SYPHON FEED"
    "Windows: Add a SpoutReceiver2 actor to the Scene Editor, and click on its ‘server’ input"
    there is no server input in my SpoutReceiver2
    thanks!

  • Tech Staff

    It's the 'Select' input. (trigger type)

    It should open a little SpoutPanel dialog (if you put spoutpanel.exe beside isadora.exe in the Isadora folder).  In that panel you can select the input source.
    If you want it 'hardcoded' to the SpoutReceiver, you will need to type the name show in the SpoutPanel into the first input of the SpoutReceiver (Sender Name).
    It is case sensitive. Also beware of whitespace (trailing spaces etc..)
    Once sent and working, save your Isadora file, and the Sender Name will remain.

  • ok thanks dusx

    I was actually expecting a "drop down dialog, displaying all the active Syphon servers on your computer", as the tutorial states, but I only see the "depth 640*480"
    I realized however to modify the sketch in processing in order to send either rgb camera image // infra red camera image // depth without colored bodies of tracked bodies // depth image with colored bodies of tracked bodies

    @camilozk

    It seems you might be confusing Spout with Syphon.
    If you are on a PC you will be dealing exclusively with Spout.
    If on Mac it will be Syphon.
    if you wish to share you code modifications regarding the video sent to Isadora, I am sure other users would appreciate the information.
    (if you post code, wrapped in html PRE tags, the forum will auto format the code. It must be done in the html edit mode.)

  • Tech Staff

    Am I right in thinking this will only track one person at a time?



  • Dear @Skulpture,

    Well, yes and no. I had at least six people in the frame at one point and they all had Skeletons. But I didn't revise the code to _handle_ those multiple skeletons. We should make this change. I can't do it at the moment with my coding responsibilities for the main program, but maybe someone here has the desire to make it happen?
    Best,
    Mark


  • Hello,

    I am running Izzy version 2.1 on a mbp retina on yosemite. I have followed all the steps for this tutorial, I have run the processing sketch  and have an image coming from the kinect in the viewing box, but there is no skeleton image..am I missing something?
    thanks


  • Hello,

    It works great...thanks a lot for all.
    Best,
    Pascal

    @ leben

    It can take sometime. You need to stand in front of the kinect, allow it to detect your figure (will color your form a solid colour)
    After a little while (if your form is clear) it should switch to adding the skeleton. (this process is very cpu intense, and on my PC almost freezes things for a couple seconds) but once in this mode returns to performing well.


  • yes it works great! i was just wondering if there would be a possibility through processing to get kind of a ghost image and/ switch between different possibilities?

    @gapworks

    Like @mark mentioned in regards to tracking multiple skeletons, switching the video feed would have to be added to the Processing code.
    I imagine that OSC control of the video type could be added.
    Perhaps a Processing Pro in the forum might take this one and share the final script.


  • @ DusX

    All is working fine. Thanks for the help, and to those who wrote the tutorial. this all very exiting

  • Tech Staff

    Thanks all for the wonderful comments and helpful feedback. Get out there and make some cool art :D


  • Tech Staff

    I am guessing from the screenshots and from my own patch that all the red text (errors?) that show up in Processing patch are normal?



  • "I am guessing from the screenshots and from my own patch that all the red text (errors?) that show up in Processing patch are normal?"

    Copy & paste a sample - all library initialisation output is generally red by default... so __shouldn’t__ be anything to worry about, but I can take a look.

    "Like @mark mentioned in regards to tracking multiple skeletons, switching the video feed would have to be added to the Processing code.

    _I imagine that OSC control of the video type could be added._
    _Perhaps a Processing Pro [user] in the forum might take this one and share the final script."_
    Can do... but probs not til the weekend.
