- 2Deluxe, on 11/10/2008, -2/+16Wow, I'm pretty sure i've seen this before but its still damn cool.
I think the major hurdle involved with '3D' technology is capturing it, until there's an easy way to record video from all angles there's probably not going to be any decent ways of displaying it. Yeah, I know CGI is common place but still, 99% of television is live-action. - vtbarrera, on 02/03/2009, -1/+15This + Porn = Epic WIN!
- phate2292, on 11/11/2008, -1/+15That solid case around it would stop the shards from slicing through people. They hope.
- nurbsenvi, on 11/10/2008, -3/+16What if that mirror breaks apart at that speed?
- ivencente, on 11/10/2008, -2/+11pretty soon i won't know if I'M real or not. I might be a hologram. I feel so hollow
- Murdats, on 11/11/2008, -0/+7duck.
- totosushi, on 11/11/2008, -1/+7Help me Wireframe-Kenobi, you're my only hope...
- inactive, on 11/10/2008, -1/+6Cant wait for the webcam connectivity so pervs can send their "3D" packages all over the place.
- Killbot2015, on 11/11/2008, -3/+8REAL HOLOGRAMS: http://www.io2technology.com/
Projected straight onto the air, no smoke AND no mirrors. - cloudberries, on 11/11/2008, -1/+6Awesome! I just hope they come up with a version that wouldn't slice off my fingers if I prodded it.
- DelMonte, on 11/11/2008, -2/+6I dugg this because it's a volumetric display, and I love volumetric displays :)
Still, I don't think it's the best method, since it only works horizontally. The shot where you can see the top of the head was done by tracking the camera position and adjusting the image accordingly, and this pretty much defeats the advantage of a volumetric display.
As far as spinning volumetric displays go, they should've used an helicoidal spinning screen like the Felix 3d system, though I guess it requires more brightness and resolution, and it's (probably) patented by the Felix 3d company.
As for one day being able to project 3d images in thin air, there's a fundamental problem with this, which is air turbulence. - threat42, on 11/11/2008, -1/+5Dugg for nerdy appearance of Star Wars TIE Fighter within less than a minute.
- absentmindedjwc, on 11/11/2008, -0/+4what if they use this plus the CNN "hologram" technology..
that is able to capture, process, and broadcast 360 degree shots
Make their ***** not so hologram into an actual hologram - TekTrixter, on 11/11/2008, -0/+3GOOSE!!!
- LeviTheSmith, on 11/11/2008, -1/+4I love living in the future!
- nurbsenvi, on 11/11/2008, -0/+3Money shot will be scary.
- linagee, on 11/11/2008, -0/+3Spinning mirror 3d = very 1990s.
- hadak, on 11/11/2008, -1/+4Old but cool
- MCA2142, on 11/11/2008, -2/+5Before tube TVs there were Mechanical Wheel TVs.
And now we have a Mechanical Mirror 3D displays... What's next? Can't wait!!! - DelMonte, on 11/11/2008, -0/+3The Heliodisplay you linked to is not a "real hologram", it's flat, like a flat semi-transparent screen.
While it's impressive that they managed to project images into "thin air", there are many problems with this approach.
The first one, which I talked about in my previous comment, is that air turbulence causes constantly moving distortions and uneven brightness changes in the image.
I've seen it in a video demo, and the Heliodisplay is what made me realize that there's this fundamental problem with trying to project images in "thin air".
Second: you don't see it in most of their promotion material, but a projector is needed for this to work, so you can't walk around the image without the risk of obscuring the image.
Third: A problem shared with most volumetric displays, the whole image is semi-transparent, with the transparency being inversely proportional to the brightness of the pixels. It can't display anything opaque, unless the brightness of a region is superior to the light coming from the objects behind. It cannot display dark opaque colors, like black, unless you turn off the lights. - cloudberries, on 11/11/2008, -0/+3You could emulate the experience by having someone throw broken shards of spinning mirror at your face.
- DigitAl56K, on 11/11/2008, -0/+3It's only spinning at 20Hz, but the projection itself changes at 288hz.
See this vid: http://www.youtube.com/watch?v=FF1vFTQOWN4 - Jektal, on 11/11/2008, -0/+2Deep.
Not your soul of course, that's shallow like dumping your ex-girlfriend for that mole she had, but the statement, that's deep. - socialexpert, on 11/10/2008, -3/+5It is the optimal display for future TVs.
- Jektal, on 11/11/2008, -0/+2It's my dick in a 3D projected box!
- williamkusumo, on 11/11/2008, -0/+2Hey, my girlfriend works there!
- inactive, on 11/11/2008, -0/+2I won't be happy till I can put on 3D glasses, walk outside, and see the world in 3D.
- Meocross, on 11/11/2008, -0/+2duck.
- lelux, on 11/12/2008, -0/+1Definitely a problem if you're using it for porn.
- Jektal, on 11/11/2008, -0/+1Well, it -does- solve the fingerprint smudge problem...
- RAAFStupot, on 11/11/2008, -3/+4While I love this technology, I can't really see it replacing 2D displays for all entertainment purposes - for a few reasons.
Firstly, when we watch a 2D screen, our brain reconstructs this into a 3 dimensional 'scenario' the size of which is independent of the the size of the 2D screen. To illustrate, if I watch the Battle of Helm's Deep on a 24 inch flat screen I'm instinctively aware of, and impressed by the 'real size' of the scene - but if I watch this scene on a '24-inch diameter' 3D display, it will look like a bunch of 1cm high figures running around. Great for a technical analysis of the battle, not so great for the drama of the battle.
Secondly, a 3D display 'gives away' a lot more than a 2D display. Creators can use this 'limitation' of the 2D display for dramatic effect - for example by hiding a character from the viewer's view until a crucial moment. The 2D display gives the creator the power to unfold the story at his / her discretion, rather than the viewer just (literally) 'going around the back to take a look'. One of the great things of the 2D display is that it FORCES the viewer to watch carefully composed scenes.....ranging from long shots to extreme close-ups.....
Thirdly, how would sound effects be implemented in a 24 inch diameter 3D environment????
We have already seen how static 3D images have not really supplanted static 2D images - sculpture has existed alongside, but not replaced, painting, drawing, & photography.
Where I can really see this 3D display technology working, is more in technical fields (eg. briefing a surgical team on a complicated procedure, showing the position of the tumour and the location of crucial blood vessels, nerves etc, obviously architecture & engineering), in education (eg, demonstrating to a class the concept of cubed numbers - a cube with a edge 3 units long contains 27 individual cubes inside it) etc etc
I can also see it being fantastic for the broadcast of sporting events.
Finally, that mirror spinning at 25 000 rpm would do a lot of damage should it develop a crack (hope the enclosure is solid), plus the gyroscopic forces must be significant, so perhaps a portable version is a while off.
I can see people laughing at this in 100 years time. "They actually had to use a spinning mirror in the display, just like John Logie Baird used Nipkow discs in the first television displays...."
Then again, perhaps I'm just a Luddite, unable to envisage the fantastic new creative endeavours that this technology will open up for us!!!! - DelMonte, on 11/11/2008, -1/+2"Well at least the Heliodisplay actually IS a hologram."
No it's not.
http://en.wikipedia.org/wiki/Holography - Meocross, on 11/11/2008, -0/+1To cut it short 2D has much more freedom than a 3D display, pretty obvious really.
- dkeck14, on 11/11/2008, -2/+3When they started that machine up...it looked ***** awesome. That could fit wonderfully in any sci-fi movie.
"Hold on, we got an incoming transmission"...whir up the machine and watch the incoming head flip and distort 20 times before snapping into position.
Much like star wars approximation of what 2D displays would be like in the future, we could look back and laugh at how rustic things in the sci-fi future looked. - SiXiam, on 11/12/2008, -0/+1I would be modeling Cotana and not some stupid face...
- SiXiam, on 11/11/2008, -0/+1Exactly: This is a step along the way to true hologram tech...
- Killbot2015, on 11/11/2008, -2/+3Well at least the Heliodisplay actually IS a hologram.
- Recidivus, on 11/11/2008, -0/+1When I saw this I was expecting it to be on of those "old" spherical ones, made by Actuality. Uhm, Perspecta is what they were called I think.
- techdever, on 11/11/2008, -0/+1i like turtles
- Recidivus, on 11/11/2008, -0/+1"Where I can really see this 3D display technology working, is more in technical fields"
That is exactly where it is right now. Medical, mining, oil/gas, fields where having a fully 3D interactive display serves a purpose other than "Cool". Several companies already sell them. - DelMonte, on 11/11/2008, -1/+2This article doesn't talk about holograms, and io2technology never claimed that their Heliodisplay could project holograms, and they should know better than you, since they created it.
You really don't know what you're talking about. - 0tis, on 11/11/2008, -0/+1But... holograms. 3D TV! This is the last hurdle before I get my rocket boots.
- halo3d, on 11/11/2008, -2/+2imagine gaming on a 30 inch 3d screen.. *Drools*
- linagee, on 11/11/2008, -1/+1Burried. They didn't do it right. The image should be semi-stable at spinup if the encoding data (position of the mirror) gets fed back to the display algorithm.
- d0o0fy, on 11/11/2008, -0/+0I still prefer CNN holograms
- jalso, on 11/11/2008, -0/+0real 3d display:
http://www.holografika.com/ - inactive, on 11/11/2008, -1/+1It'd still be ***** pointless for CNN to use it when they already have perfectly good split-screen technology.
- chriscast, on 11/11/2008, -0/+0Yeah, it was shown at the last SIGGRAPH.
