  • @sadunkal your a fucking dickehead.

  • @nightmakerrecords No, on the contrary, he's very insightful. Check the comment he made a year ago about Project Natal, and compare to our Kinect videos to see how right he was.

  • This is amazing, just think of the possibilities.

    Talking to your son whos halfway around the world, and hes right infront of you.

    Think of the video gaming experiences.

    Awesome for education....show your students exactly what you are talking about, like its right in front of them

    I love technology...

  • @p4tr1ck77 I imagine a recording of a someone passed on, and then sitting in the same room with them, as they talk to you. Maybe not a conversation, but the idea is still pretty awesome.

  • is it fake ?

  • i assume the dancin women were recorded with 50+ surrounding cameras right?

  • 48, to be precise; twelve independent clusters of four cameras each. Each cluster reconstructs a 3D facade. To see what it looks like with only two camera clusters, check out the other video ("Collaborative Visualization with Tele-Immersion").

  • Wouldn't motion capture+3D scanning/texturing (beforehand) produce better results than these? Ultimately it's bound to be less realistic than a theoretical perfect camera capture, but with all this 3D noise it's not very immersive either. Or would it still be cheaper and less time consuming to invest in many more cameras (100+?) than motion capture+3D..?

    Motion capture also has the advantage of enabling people to be different things than what they really are of course. Like in second life.

  • Yes, absolutely. There is a very impressive method developed at a Max Planck Institute in Germany (google "Christian Theobalt") that does just that, and gives much better results.

    However, it needs very carefully pre-made models (and it's not real-time yet, either). The fundamental benefit of the method shown here is that any random person (or animal) can just walk into the capture space, and will show up on the other side immediately. It's more like a public phone booth in that way.

  • Oh, and guess what? We're working on motion-captured avatars right now, for exactly the reasons you state. Keep looking.

  • Oh, ok. :) Keep working on it, it's the future...

    And when you say that "it's not real-time yet" are you referring just to the modeling or does also the motion capturing require time to process?

    ...

    I just noticed a paper by Theobalt et al. from 2005 where they "present a self-calibrating framework for optical motion capture, enabling the reconstruction and tracking of arbitrary articulated objects in real-time". You mean there are still problems with real-time motion capture of humans?

  • Sorry the paper is only cited by Theobalt, not authored by. It's actually from Aachen University, by Hornung and Sar-Dessai.

  • Ow alright. I think I just found the "very impressive method" you're talking about; "Performance Capture from Sparse Multi-view Video". It's very impressive indeed, especially since it's done just with 8 cameras. And I can understand how it's not suitable for real-time, yet. I was imagining a lower quality motion capture and a less detailed model/texture when I made the above comments. :)

  • That's the one. Christian presented the method to my group a few months back, and I wanted to start using it immediately, but unfortunately he told me then that it took quite a bit of processing between capture and playback. So I shelved that idea for the time being. :(

  • Maybe all you need is an Xbox360. Check out "Project Natal"... It surprised me. It's not yet exactly clear how precise it is though.

  • you can look but you can't touch

  • how da heck

  • that is SO cool! (and kinda creepy too) :) I keep expecting Princess Leia to pop up :)

  • Princess Leia? No. This is imperial technology!

  • This is the future folks

  • Why he wear the glasses? LOL

    They guy will have a great headache after that (I have tried) :P

    Nice video, BTW.

  • The glasses are still necessary to create the 3D illusion for the viewer. Sorry to hear about your bad experience, but you should try again some time. This is not your old VR. Our users sometimes use the CAVE for hours at a time, and I haven't gotten complaints about headaches or anything yet.

  • What do you use, shutter-glasses or polarized filters?

  • These are shutter glasses. They work better than polarizing ones, especially with an enclosed multi-screen setup like this.

  • i wonder what it takes to render something like that?

  • The best part was when he started rotating them around as if they were just 3d models, but looks cooler because they look like real people and your rotating them around with the graceful flow of a 3d interface. Noice!!

  • Dali would have loved this

  • Absolutely excellent. This is the future.

  • OMG! this is the best! omg try to get a contract with nintendo or something and make a mmorpg that can do this!

  • Oh i get it, it's like a virtual Area.

  • its like a star trek hollowdeck

  • Are they holographs?

  • Sort of. The people were captured by an array of cameras, and the resulting 3D data is displayed in an immersive environment (the CAVE). All images are projected onto the CAVE's walls and floor, but to a user (or, in this video, the camera) they appear to be standing or walking in space like holograms.

  • I (Amber Steele, Mills Dancer) got to dance in the tele-immersion space at UCB CITRUS Lab all spring; we were dying to see this next step occur! It looks fantastic! I'm going to cite this in my thesis; but if you need dancers again, I would love to return!

  • whoa, that looks pretty creepy actually
