@Alphamodule the difference from the laser on the spiral is this can produce 3dimensional opaque surfaces, while the spiral will show everything overlaid regardless of depth and expected occlusion
My understanding is that the image it displays is timed so that when the mirror's at a particular angle, it displays the image at that angle. So what you see depends on what angle of the mirror you see.
ok... Only posting this because i saw the Tie Fighters at 1:00. But the last demo of the man running reminded me quite a bit of the star wars holographic communication. Very interesting stuff. Hope to see more!
@meneerlies , I don't agree. Let's say that you place a diagonally placed monitor and revolve it like in this demo. And rotate it 360 degrees. Now let's furthermore say that you display ONE frame that contains ONLY the 3D data (pixels) for that particular position (not the entire image), and on the next frame (1-degree) you continue with the scan from the object and place the next pixels, and on the next frame (2-degree) you do the same again and again until you have a complete 3D model.
I love how it wobbles in all directions while spinning up, makes the thing feel more oldschool, like CRTs back when you had to tune all the oscillators manually
when will this type of technology be out for the consumer market? either way that's badass, can't wait for this to be implemented on household items to cars! behold the future of techonology is tommorow.
WOW! How original! who would have thought that a mirror would make it possible! However if i were to stick my hand through the hologram, it wouldn't look that pretty! LOL!
That's pretty cool, it's spinning some hairy rpms though to give such an optical illusion. I wonder what kind of show that thing would give if a bearing or some screw let loose. I'd hope that scatter shield is up to the job!
Imagine living in 2D world, intersecting a 3D object. Thinking about that, it's clear to me that the fourth spacial dimension is an array of parallel 3D universes, just as a 2D creature would perceive a 3D object (like a basketball) as an array of parallel 2D universes. So a 4D creature is an entity whose every movement spans many universes like ours and changes them fundamentally. Hard to say if it exists though.
Hm.. No, the mirror's turning so fast that it's reflecting right all around. And the computer knows what speed the mirror's turning at, so it outputs the image for angle 0 at position 0, angle 1 at position 1, etc. So whatever angle you look at it from, you can see a reflection for *that* angle, since the computer is displaying the image for *that* angle when the mirror is at that position.
actually, some movies would be possible. 3D animated movies would work on this. I'm predicting pixar will probably make a film for this thing in the next 10 years.
Thanks for the inspiration ! I found the ultimate way to produce real 3d hologram with very high resolution. Now all i need is to wait few years go have the missed piece of technology.
+Nobock nice but can you prove it... my hologram can record and display real light fields and no tracking is needed..it was so ridiculously simple its scary. but it pass the criteria of being a hologram with flying colors
This might be using the same technology as holographic displays, meaning that it will render a 3D-object, in all 3 dimensions at once. Everyone will see the object according to the angle they view it in. But the image would be slightly transparent, and you would have to sit in a dark room to get the best possible quality.
That's really cool! I've seen some others using projectors that project into a jet stream of air, which produces a hologram of sorts, but it is nowhere near as clear and nice as this one is!
when i saw this i thought of the exact same thing.. someone showed me one when i was a kid ant it looked like it was really there.. cheers for mentioning it, ive finally found out what it was!
IIRC, In a second, it makes 15-20 rotations. So assuming that it displays an image for every degree (and there are 360 degrees in a rotation), in a second, the computer outputs 360 times 15 or 20 images. I could be wrong, but I'm pretty sure this is how it works. I'm also pretty sure that I didn't explain it too well. :p
OH! I didn't see how that worked, when I saw the begining again, i realized how that worked. Not really that amazing, but... well I've seen it done before, but its still a very nice effect, and a great idea to make each angle different. What program did you use to make it different at different angles?
You can ask the same question about any invention. The answer is because it's not exactly easy to come up with things that have never been done before. 95% of people can't even learn to reproduce things that have been around for ages.
Acsually, I believe is more like this: the projector on the top is in the sync with the spinning speed of the mirror, and sends images to the mirror in such way that the image reflected in the direction of the mirror is the perspective of the object in that direction. Long story short: that mirror will reflect a image for any position of the mirror.
This got me thinking... Could you use a spinning stream of air combined with a projector to create a hologram you can stick your hand in? I'm thinking star warsy right now. Yours is like the CRT monitor of holograms- It has a refresh rate, why not skip straight to LCDs? Probably impossible at this point... Anyway, do it with air so it's kid safe, doesn't have a translucent blur, and you can put your hand in it!
it might work well with an interface similar to that of the Wii. It could project a hologram of an opponent, then using your controller you interact with it. Such as playing tennis against an virtual opponent.
Nice effect, but anything moving at that speed is bound to break very fast and use way too much electricity, especially if scaled up to a size suitable for group TV or outdoor advertising.
Yeah but think that if a single frame of a near-photorealistic image takes possibly days to render in todays film, how long would it take to render every single angle?
@qarusel 3D computer graphics extend beyond games, e.g., pixar movies are all done with CAD. There are 3D scanners that can scan real-life objects like they showed.. who knows maybe one day they can do it in real time. Also centripetal forces will net out to 0 if it's symmetric about its axis of rotation which it would be. Vibration would be a caveat, but it could be designed so that vibration is minimized
Mckirkus, spin faster or spin "bigger"? good job on the word use. A for effort i guess. If they make it spin faster, the frame rate of the projector will not match the speed of the mirror, thus having a spinning object, and not one that is stationary.
Impressive. I think that it was a very difficult work, but the results are very high. Now I want to see how do you control miniaturization of this hw. If it can work with other ideas to eliminate mirror very tall. Only a very little plan to integrate in mobile for example
i agree as far as broad practical applications this falls short. but its is an option for something like displaying a non-invasive (and potentially high resolution) body scan. Granted, because it feature spinning glass element it would have to be placed in a plastic tube. But in comparison to other ideas, its cheap. Cheaper then a transparent OLED Block. This may have low cost medical or security applications. What does the dev team say their target application is?
awesome! But I'm far more interested in the contact lens display stuff. Way more potential for practical use.. No lasers or mirrors that spin hundreds of times a second...
regular VR+web = interact with virtual world & other humans from anywhere in the world, which has many more uses surely. similary, A.R in same room would be more pervasive Still I'll agree with your point.. yes many inventions have uses that are unthinkable before they exist
This device seems to be somewhat in a prototype stage, compare to the Actuality Systems Perspecta Volumetric 3D Display which is an existing commercial product.
The predecessor to this technology used a spinning plate of LEDs, but then you had the problem of seeing the back surface of the 3d image at the same time as the front surface. This method of using the spinning mirror avoids that, making the image appear more solid since you aren't seeing all of the surfaces of the object at once.
@meneerlies , But they already to that with the rotating "animation globes" that just contains a row o RGB leds instead, you can most certainly watch that from all angles. Heck, I'm not convinced that can't be done at all. If you rotate a monitor, time the lit-pixel at the exact position, how is that not 3D in X.Y,Z space when it's rotating?
This idea is brilliant! If simple calculators can turn into earth-orbiting Satellites, then these mirror-spinning holograms can become ... uh... a way to harness the sun's energy? ¯\O_o/¯
This solution works great with multiple people watching, but if it's just One person, you wouldn't need to rapidly spin the screen, just track the viewer's position so the screen always turns to face them (and the drawn image changes to match.) That would allow for much higher resolution color images.
What sort of projector are you using? I can't imagine my home theatre projector's refresh rate would be anywhere near close enough to mimick this technology.
this is actualy smart. the image is sto fast rotatating that you see the dark thing around. Its in glass probobly becouse there is vacuum inside to make the rotation easier.
@danya101 You mean centrifugal force is a 'fictitious force,' not that it doesn't exist. (Though I guess it probably is centripetal forces that would be working on the mirror)
i dont understand how it slowly changes from a side to front perspective as u move around it? if your only using 4 projectors or something how come it changes angle so smoothly? or is it tracking where the camera is and drawing it relative to where u are through just 1 projector?
@nervon i think he is right. Of course one could simply create a new set of camera which produces a 3D computer graphic of a scene instead of a flat image... but spinning a mirror is really a not very practical way...so this technology seems pretty useless
Infelizmente, parece que esses hologramas podem ser vistos ao redor de um único eixo só. Não teria, por exemplo como ver o topo da cabeça do primeiro modelo.
so, at a set angle, the display refreshes that particular prospective of the image? thats the only way i can figure out how you can't see the hollowed inside of the image...
"there was already a hologram video game in the late 80s, something to do with shooting cowboys!" Oh ya...SEGA's Time Traveler. Played exactly like Dragon's Lair, only you had TimeCubes you could use to reverse a fatal mistake. I think they also made a fighting game using the same hardware.
generate the movie in a computer. scan real life actors if you want to use them(why bother, theyre expensive). were getting to the point where you cant tell a real scene from a generated scene anyway.
I'm not sure this is viable, the larger you make it, the more exponentially dangerous it becomes, from an engineering stand-point you have to prepare for it to fail, and if it was the size of a 20 inch screen you would probably need about a half inch to a whole inch of bullet resistant polycarbonate between you and the image.
maybe the star wars holograms communication won't be too far from reality. I just hope people won't confuse that "light field" as a real object, as that rotating mirror is quite fast XD.
This was probably not a hologram but a virtual image, easily created with a concave mirror and some semi-transparent glass. In fact you can purchase something similar to this, type 'mirage toy' into Google under image search ;) This demonstration is so different mate that we are talking some sh!t hot technology here...
I'll bet you could get Carrie Fisher to put on her Leia outfit one more time to record her "Help me Obi Wan Kenobi. You're my only hope." speech for the 3D camera for the demo.
i lived long enough to see this. i'm grateful

This is the coolest thing I have seen this week.
My spine is tingling and I can hear the theme from STAR TREK in my mind's ear.
*This* is what the 21st Century was supposed to be about!

this guy knows everything and has seen it all... are you god?
This is cool! Though in its early stages, wish it would be compacted in the future and most importantly... CHEAP for the masses!
That's really cool! I've seen some others using projectors that project into a jet stream of air, which produces a hologram of sorts, but it is nowhere near as clear and nice as this one is!

Screw 3D porn. Where is the hollodeck?! :) No, seriously this is absolutely mind blowing! Kudos to the guys who came up with it.

@qarusel No, man. It only spins one way, like a fan. Even if it would need to be enclosed in a box, it would not be expensive if mass produced.
Nice!
And unlike some other designs, it has finger chopping protection too.
This got me thinking... Could you use a spinning stream of air combined with a projector to create a hologram you can stick your hand in? I'm thinking star warsy right now.

simply awesome!! The future is here!!
Why not use a monitor display instead of the mirror? Rotate the monitor tilted, just like you do with the mirror?
it might work well with an interface similar to that of the Wii. It could project a hologram of an opponent, then using your controller you interact with it. Such as playing tennis against an virtual opponent.
Wow ... this is insanely awesome!!!
sweet if they advance technoligy like this. then this could be the new tv. playing games on this would be amazing!
Wow... this is very very interesting. I like this work. Wish I can be part of it.
Nice effect, but anything moving at that speed is bound to break very fast and use way too much electricity, especially if scaled up to a size suitable for group TV or outdoor advertising.
Thats actually pretty awesome !
Yeah but think that if a single frame of a near-photorealistic image takes possibly days to render in todays film, how long would it take to render every single angle?
Sweet! Just a few more years and we'll have flying cars! :D
Bring on the exciting 3D action!

oh right, i understand now :D it basically beams a different view of the model out to every angle so it appears 3D from all angles, i getcha :D

best i've seen, impressive indeed, thought of something similar but obviously as a average guy, no way of trying it out. keep up the awesomeness :)
Interesting. You can use it in museums.
Reality in a box, coming to a living room near you by 2015 at the latest, coming to a THEATER by 2020..count on it.

tracking user's position... what a good idea. thx!
Haha, it HURTS! Great comment. They didn't call it a hologram in the description, though.. Only one of the tags say "hologram", strangely..
What sort of projector are you using? I can't imagine my home theatre projector's refresh rate would be anywhere near close enough to mimick this technology.
It is a touch screen?
lol
This is really awesome
Was it really noisy? I can see that being a problem. Though I'm sure there are ways to cut down the noise.

It was good, but it is still a projection onto a hard surface, not 100% an hologram.
that's really really really REALLY cool
so, at a set angle, the display refreshes that particular prospective of the image? thats the only way i can figure out how you can't see the hollowed inside of the image...
Beautiful!

put an LCD on a rotating base that tracks your head using cameras :)
personally looking forward to oleds..
Ahh I'd love to have this instead or in addition of my regular 3D screen :-)
you mean like putting a mirrored casing over it so you can see it like that plastic pig illusion. you might just be onto something there
this is brilliant!
@qarusel 1. U cn also watch movies in it
3. spinning mirror is not wind but dangerous....
love it keep up the good work

This is so freaking cool!
Incredible !!
Someone know the resolution of this display?
but doesn't that mean the system only works for 1 viewing angle and not all angles?
Simple and effective, I always wanted a TV where i can go behind the news anchor!!!
I’m sure it will be heaven ^_^
can't wait for the future!
