    Scratchpole Hmm still thinking...

    Very impressive, but I cannot quite tell from the photo's what you did in terms of the tracking/masking... any video to come?

    Yeah should be coming along soon, my battery just went as I was getting my lores off the camera, but it was filmed by Strukt, for documentation which will be higher quality and edited rather than a shot from the back of the room... The dancers were lit by the projections, tracked for particle systems, for most of the scene's, except the uv, and pyro bits, and the hoops were tracked and capsule gfx projected onto them.

    awesome! baffles me how you can motion track so many objects.

    Looks great cat....what were you using for the warping/how many machines etc and what material is on the cylinders.

    All done in vvvv, 1 machine with 2 outputs for the Cylinders, 1 for the tracking.
    Cylinders were half circles of wood top and bottom, with a grey projection film stretched between.
    @asterix, its all camera tracking, things appear as blobs with id's and x/y positions, same as multitouch stuff really, were using custom tracking software though for the hoop detection, all that was a bit tricky!

    Loved it. looks PRO
  9. I'm really amazed by this... can't wait for a video to see it in action !

    How did you manage communication bewteen the video tracker and your projection software ? I don't know vvvv in fact...

    Brilliant work mate. Congratulations. The behind the scenes documentation is really informative too in its simplicity. I look forward to trying out a few of your ideas.

    very nice and pro result indeed !
    loved the straightforward behind-the-scene documentation too.

    this live performer masking and tracking issue is getting mor precisely addressed everyday now, it's really interesting to see the various techniques that are being used.

    you were obviously working with very professional tools here (as far as beamers, cameras and infra-red projectors are concerned at least). do you have an idea of the global cost of the installation ?

    in a much smaller scale, 1minute69 (young collective I'm member of) started working on an interactive audio visual performance involving body projection mapping. I'd be happy to get some feedback from you all about it :


    in this workshop, the tracking and masking is done in Isadora with kinect + quartz composer plug-in (video projection is also controlled in Isadora)

    can you tell us what cable type was used between camera / computer and computer / beamer ? and if you encountered some latency issues with the devices involved, or not really (i.e. too subtle to be seen by the human eye) ?

    thanks in advance, and congratulations again for this great great work !

    Thats really nice :)
    Latency is always an issue with tracking, theres delay between camera and pc, delay as its tracked, and then delay from pc to screen with the beamer too, you just have to enlarge your masks and hope that its enough!
    I'm afraid I've no idea of budget for this as I was wasn't involved in the organisation of it...
    The camera was a ui gige cam, and was etherneted to the pc's, then DVI to the beamers

    well, thanks already for these answers !

    as far as the latency issue is concerned, it's an interesting and quite unusual idea that you bring up when you say "you just have to enlarge your masks and hope that its enough!"...

    never imagined such a solution, and actually I think I don't really understand what you mean ?

    congrats, Cat !

    in the meantime, 1minute69 presented the B0DYSC4PES performance at the Live Performers Meeting in Rome.

    here is a video of what it looked like :
