Rulr Tutorials or other Kinect 2 + Projector Calibration


#1

Does anyone here have any Rulr video tutorials or session videos? Everything I’ve seen is Hackpad links which all redirect to Dropbox Paper landing page, even when logged into Dropbox.

Or, any vvvv Kinect 2 + Projector calibration? Elliot Woods posted several video guides to his Kinect + CalibrateProjector workflows, but they’re for Kinect 1 with OpenNI, and also I can’t find the special patches he made for it.

let’s try to get @elliotwoods on this…

Sorry to bug you @antokhio, could you share any info on working with it? Found a Youtube video with your name listed as leading a workshop on it.

Also if it’s still somehow possible to get into Hackpad, @nrsz said there are Rulr videos at this link: https://rulr.hackpad.com/OpenDot-Workshop-Day-1-6I5zRGv9TaK.

Hi, don’t have kinect or projector at the moment to do a full video… but ill try to do quick doc when I’m able…

unfortunately all of the hackpad links stopped working, even the download link on http://rulr.xyz/ is going nowhere…
@elliotwoods - would be great to know what’s plan for rulr!

@antokhio - anything you can provide is appreciated. I’ve seen a few other posts asking about calibration and Rulr so I’m sure others will find it helpful. Definitely didn’t expect you to build out a whole video. But if you get bored someday…

@nrsz - thanks for clarifying.

I’m not surprised Elliot isn’t responding as Kimchi and Chips is wrapping up their latest project, Halo. The Creative Applications Network writeup says they used Rulr, so there’s hope.

Hi here is few screenshots describing procedure, as i remember it…

Thanks for the lead. Unfortunately, ran into a few issues.

  • I couldn’t get Visual Studio 2015 x64 Runtime to install due to having another version installed (I assume 2017). No problem with 2013, oddly.

  • When I open the Rulr application I get this message (though the Kinect camera still shows up in the Rulr preview):
