A look back on popular stories from today in a specific year.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Bah, I knew I got it wrong. :(
But does it play 3D doom?

this looks more promising, no need for water vapor, but no color either
The key here is that this technology can't go very far without an easy way to render content. In order to feed a live football game into a 3D display, I'm going to have to shoot with 2D for Color and some type of LIDAR (Light Detection and Ranging) at high resolution and at a rapid refresh rate to make Sunday in 3D possible without actually going to the game. This much data is going to need to travel on fiber, which FTTP (Fiber To The Premisis i.e. Verizon FIOS) is still in its infancy. Best bet, iTunes in 3D. I'd say we're still 15 to 20 years out on this even with the exponential increase in technological development.
Any bets that we will start seeing airvertising based on this technology (a la Minority Report) within the next few years?
Wow, can you imagine the possibilities for screen savers, or mp3 visualizations?
Baby steps, baby steps, love it love it. How far is the Holodeck?

i saw this at siggraph, and honestly, it's not as impressive as the other emerging technologies for 3d displays out there
Holy shit, this is good stuffs.
am i the only one to think that this could replace animatronics on rides and such? all they have to do is scale it up and put in lots of color and boom there you go. this is way kool, the only thing i wonder is how loud it is. cuz that could be a problem with rides and such. but hey its new right?
Yes, because huge mirrors spinning at 20 revolutions per second is a good idea :)
No denying it's amazing but if i understand it, it tracks the eye (in the video's case, it's the camera) to display an image based on the eye's position.
Is this correct?
(project a hot ass girl - glass cage) + horny guy clueless of mirror = rofl
Ok, I'm no expert here but I've been following the types of displays for a while now looking for the most promising technology that gets it closest to the movies and also is the most practical. I was looking at this one on youtube last night and it is impressive but, in my opinion, is not the best out of all the possible contenders. This one would be best for immediate applications in medicine, like in the video where the cancer patient is looking at his tumor on it. As far as r2d2 projection goes the the current leader, i think, is the heliodisplay. (io2technology.com) Problem with the helio though is that the images are projected onto a sheet of air instead of being "rendered" in the air. I do love it though and it does look cool, specially since it is interactive and you can pass your hand through it! You also have your 3d phillips display which sounds pretty nice but still not quite a cigar does it make. The system that vizoo (vizoo.com) has created is very nice as well and, while it takes up a good deal of space, is gonna be perfect for shows n stuff. Last(to my knowledge at least) and certainly not least though, is the AIST 3d plasma display. Now I may not have worded that correctly but you know what I mean. I found a very good recently updated article on it here http://www.pinktentacle.com/2007/07/aist-improves-3d-projector/ and a cool vid of it here. http://youtube.com/watch?v=He2QTpelAjE&mode=related&search= Of all the technologies, this is the one that is most exciting. Dangerous, of course, but I have no doubt that given 50 years or so(maybe even less?) they could find a way to make it much safer and maybe, just maybe, touch interactive. It's the tech that most resembles the "real thing" You know what I mean. Lol. Thanks for taking the time to read all this. :P
astonishing!
They should've displayed the emporer or the death star at least! :D
Guys, check this:

All-be-it amazing, but as holograms go, that most certainly is not. That is a reflection of light on a solid surface. If it were a true hologram, one would be capable of putting their hand through said object. Doing so in this case would surely leave you regretting doing so.
Ahh, but a hologram has nothing to do with whether you can stick your hand in it!
That is a misconception authored by the fact that something that is a hologram can display objects occupying space where nothing currently is. This one actually SHOULD be able to do that too!
What a hologram ACTUALLY does is display light in a determined direction. What this means is all the hologram can show one image to an observer at a certain angle from the object, and a separate AND UNRELATED image to an observer at a different angle. It is by choice that the images are somewhat related - they show different angles of the same scene usually, so that it appears the flat film contains depth.
THIS little beauty is doing the same thing, in real time, in a partial sphere. Notice the wire-frame head... You can't see the lines that make up the back of it when they're occluded by the front! But you can see what's behind the head altogether! The lines that make up the back of the head only emit light in a chosen direction.
And they do the same thing with pictures and video. The video where there were negative images of the statue means they can choose what image to show at a large number of viewing angles. Thus, they could have views that paired together portray a wall that's farther away than the spinning film. In essence, it can function as a viewing portal into a larger room. Neat eh? It's a true hologram alright.
I love my USC :D
Go Trojans!! Bringing us the movies and then the movies to reality!
About the guy running at the end, it's not CGI (not in the traditionnal sense anyway). It comes from another (amazing) project by Debevec's team (http://gl.ict.usc.edu/Research/RHL/). I'm not saying that this would be a pratical way of filming for TV or movies, I'm just saying that this is not a cheap video editing trick.
The possibilities boggle the mind. Imagine a cylindrical device suspended from the ceiling or in a column in the middle of a room about a meter in diameter and about eye level from a sitting position. A vacuum inside reduces the noise to nothing when the light weight material spins very rapidly inside.
the holiest grail of all sci-fi is un-arguably FTL (that or physical evidence of god)
I cannot wait to see what this technology develops into.
This should bring a whole new dimension and a whole new wild ass price tag to those places where you go to see your babie's ultrasound in 3D.
We all know that just about everyone that buys one of these things, is going to lose at least one finger, not to mention numerous friends that come over to see this thing. People just can't help but stick their fingers in spinning things to find out if it hurts.
I distinctly recall seeing the do-it-yourself plans for such a device some 25-30 years ago in Byte magazine.
A mirror mounted 45° from the axis of a spinning turntable mounted in front of an oscilloscope used as a vector display; the article included the DAC circuitry to drive the scope and the software (8080 assembler) to drive the whole contraption.
Re: Sunny Man
The holographic diffuser is basically polarized film, although allowing for polarization in multiple directions. As the mirror spins, up to 250 slightly rotated versions of the same image are projected on the mirror. Your right eye would see one image, then as the mirror spins slightly, your left eye would see a different, slightly rotated image.
You don't see the back of the wireframe head because it was not rendered as part of the image viewable from the front, and if you move to the back, the image displayed at that time only renders the back of the head and does not include the front.
The tracking that is done isn't really eye tracking, but just enough to roughly measure how far the viewer is from the display to compute the angles between your eyes and the image to correct for parallax effects.
I'm guessing that the holographic film was used to also allow for multiple polarized vertical frames.
Not to burst any bubbles, but the polarized mirror trick is not the breakthrough here. The research says they drive the display with an ordinary graphics card, but...
The projector runs at 5,000 Hz!!
Now this is pure gold. I'm pretty sure that the high-speed induction motor driven (I'm presuming so) disk can be dealt with if the design of this device is further improved. Coming from the Mechanical Engineering sector, I can guarantee one thing for sure "Nothing is as impossible as it seems in initium".
Can't wait to see a safe, easy to use 3-D Holographic Projector in the future. Although, the biggest application would probably be in the adult industry...now that would be "Total Recall" all over again..AWESOME!
Isn't the proper name for this kind of thing "Volumetric Imaging" instead of "Holography"?
Holography is 3D projected onto a 2D surface using a laser to capture the image, and a special sort of printing to imprint the image.
Volumetric imaging is the proper name for the stuff commonly, and erroneously, known as holography in science fiction movies.
Engadget, it is NOT A HOLOGRAM. It is a really cool mirror/light display. NOTHING to do with holograms. But still very cool!
