"Watch how I can just walk around it and no matter what side I'm on I see the image the same." "He's still looking at me!" Reminds me of walking around the sprites of dead characters in the original Doom.
It's called "billboarding" in rendering terminology. In Doom's case, it used the extremely simple "point billboarding" where it rotates the billboard on all axes - if you could somehow look down the object would still face you.
They would, but lets be real, a large version of this would need a LOT of power to spin at a high framerate 24/7. This is still really cool, but it doesnt seem very practical imo
@@CahyoPrabowo Both of those machines are more complicated than the mechanics for this would be. MRIs have literal clanging bits in them and Washing machines have water and clothes. This would be more like an escalator or a car wheel.
as soon as i saw it in action, the lines artifacts and the noise instantly gave away how it works. i'm surprised that no-one else has done this before. or maybe they did for the personal use and didnt see it as something worth exposing broadly to the world.
Very interesting application of the old 'flip-book' images, which were also fun, but nice to see the tech making this a much more approachable process.
I've been thinking about these principles recently when I walk my dog past a neighbor's home with a large wood fence with vertical slats. When I stand still I can't see through the fence. There is only about 1/4 inch gap between some of the slats. But when I walk fast enough my brain can put together a pretty clear image of the yard behind the fence.
I wonder if it'd be possible to replicate the effect with a cylindrical screen using code without needing to spin anything mechanically. I think the spinning motion is what would make this hard to create and practically support long-term.
To make this on a larger scale, I would use two laser projectors at the base of the rotating barrel to reduce rotating mass. One big challenge would be providing power to the projectors.
I imagine one of the largest limiting factors to this is the large point of failure that is the motor that needs to spin the display. More physical moving components = higher likelihood of failure and higher maintenance costs. If the spinning mechanism fails the display becomes unusable as a normal display
I can picture this applied to a screen in which you have a bunch of andotropes in a line that each display a strip of the overall display resulting in an omni directional screen.
Someone needs to do this with 65 inch OLEDs :D Edit: If this thing rotates at 480RPM with 2 slits, that should be an image that feels like about 16 FPS. Wonder if rotating at 2000 RPM would give a higher perceived framerate close to 60fps. Wonder how adding more screens inside (equilateral triangle, square, pentagon and hexagon layout could all be viable) as well as more slits would affect the image quality. Very very interesting stuff.
Could you create a similar effect by having a cylindrical screen that refreshed at 450hz with a display controler that turned off columns of pixels as necessary?
What if a video of a hollow mask was placed inside cylinder? Does the face always appear 3D or does the slit alter depth perception so that it appears flat?
Ah, so the phones follow around the shade wheel. Anyway, isn't it difficult to get two phones in sync? So that one doesn't show the frame 200ms ahead of the other? I would have thought that it was easier to make one device with two displays to do this.. Anyway, clever way of doing it, hands down.
@@ebbamb Would you still be able to see it 360 degrees around the device or only 180 degrees the phone is facing? I don't really understand how you can see the image all the way around, why it would work when you're looking at the side or back of the phone with the one phone setup.
Neat invention! Speaking of moving image frequencies I had a thought the other day! It was about the newer style 3D glasses that flicker and that water hose attached to a speaker trick(where a locked wave appears in the water stream, trick. But that has to match the frequency of your phone camera and you can only see the effect on video afterwards. See where I'm going with this? :D Now what if the glasses flickered at the same time instead of L/R/L/R like they need to for 3D video? You could match the water wave's speaker output to whatever Hz that frequency is, type thing. Then you could see the water wave effect in real time! Instead of only seeing it later when you watch the video. Right? Know what I mean? Rainy day idea, sir! edit: Have two pairs and hold only the left lenses or the right lenses to match them instead of trying to mod them.
This would've been cool for the Dr. Strange "spell discs" I wanted to get made back in 2019, but I've long abandoned the idea of bothering, lol. 😂 No budget, no desire anymore, and overall, I just became uninterested in the project.
you could argue its 360° but omnidirectional is a little misleading i cant view it from the top or bottom smh though that concept makes me think what if you used a tourbillon and a circular screen you could perhaps even render a 3d image with it that has different perspectives depending on where you look from, not quite sure how that would work tho, the spinning pattern would have to be predictable/linked with mechanics and readable by a sensor to determine its current position and it would have to spin faster to make up for the other axis it rotates around

This is the future technology the 80s promised me
Well said.
Amen
amazing how simple things can still be newly discovered
"Watch how I can just walk around it and no matter what side I'm on I see the image the same."
"He's still looking at me!"
Reminds me of walking around the sprites of dead characters in the original Doom.
Exactly what I was thinking
I got that reference!
Many games had that

Advertising agencies will love this... more exposure to more people.

@@maxave7448 you can just put really light screens inside a vacuum
If they could do this in the movie theaters, then it wouldn't matter which seat you got anymore
Yeah but they'd need to be built like coliseums
imagine how big the spinning drum/ cylinder would be, and the sound would be loud as washing machine or MRI
@@CahyoPrabowo Both of those machines are more complicated than the mechanics for this would be. MRIs have literal clanging bits in them and Washing machines have water and clothes. This would be more like an escalator or a car wheel.
It would create such a noise it wouldn't be worth it. Turbine cyclone 🫡
Until the rotating platform ejects a huge screen at you.
🎶It always feels like somebody's wAAATCHin meeEe🎶
2:08 The guy who invented this must be a fan of Riven.
I yelled at the screen. I was so happy to see that
Had the same thought lol
Nah this is borderline witchcraft
There's no such thing as witchcraft stop watching stupid movies like The Craft.
Perfect for when you need to binge and spin at the same time.
Crazy how he made it look like the viewer from Riven
Perhaps try a wireless PC monitor, put it on top or below and use peppers ghost reflector which is what spins

It's like trees in old video games where it's just a sprite always facing the player.
This is like looking at a 2d picture that is always facing the player in a 3d game
u mean vision pro?

"I GOT 2 PHONES 🗣💯📱📱"
One step closer to "Help me Obi-Wan Kenobi, you're my only hope!"
very good pick! simplicity is the best
That's so coo!
I can see this being implemented into tvs oneday, and some people will set up their livingrooms wit circle sofas around the tv!
Why would you ? We are gonna have super comfortable AR glasses by that point
Unless you're a family of 20 people, that seems completely unnecessary
it'd take up a space equivalent to a cylinder of the TV's half-width. I'm not sure it'd be practical to use for anything but portable TVs
This helps us play Doom in real life.
I wonder if it'd be possible to replicate the effect with a cylindrical screen using code without needing to spin anything mechanically.
I think the spinning motion is what would make this hard to create and practically support long-term.
Good idea. However, if you use it for theater or TV, the surround sound effect will be screwed up. Sound has to come from the center device only. 🤷♂️

It does feel like those PNGs in 3d games that follows you
I think the term is a 'sprite'. A 2d image that's always oriented to directly face the game's camera.
@@atomic_wait More specifically, the image itself is the sprite, while the effect of always orienting to the camera is called 'billboarding'.
Mike Andos is about to become a very rich person!
Since it's very fitting for the flat sprite style: can it run Doom?
I imagine one of the largest limiting factors to this is the large point of failure that is the motor that needs to spin the display. More physical moving components = higher likelihood of failure and higher maintenance costs.

0:38 bruh thats creepy 😅
This can be used in many places. Surely something that can change the world, for better or/and worse.
I can picture this applied to a screen in which you have a bunch of andotropes in a line that each display a strip of the overall display resulting in an omni directional screen.
That opening CRT screen text should have said "Hello world".
They had a bunch of these at the Metallica concert I went to.

well this will make adverts EVEN WORSE
Great idea, but I think it will be very inpratical with 72" tv's, although you don't need your ceilingfan anymore
It would be funny if you told the time at the airport scene.
Great, now my boss can catch me slacking off in 360.
Maybe get a skilled trade instead of a fucking boring-ass desk job.
Always a great vid
You haven't even watched the whole thing!
This is an effect that truly looks edited in, trippy
4:15 surprisingly I even though about hollow mask after seeing the thumbnail
2:03 is that the thing from Myst or Riven?
Could you create a similar effect by having a cylindrical screen that refreshed at 450hz with a display controler that turned off columns of pixels as necessary?
no
no, it would be a blur, you have to block the light from getting to people at different angles
Wow you really got that 1993 hairstyle down. 😂
Will be used everywhere: For advertising.
yes this simple device has potential....
Again, watching before the Mark Rober vid! Realized you live down the street from me!
Imagine pulling pranks on barber shops by swapping their pole out for one of these
What if a video of a hollow mask was placed inside cylinder? Does the face always appear 3D or does the slit alter depth perception so that it appears flat?
Good editing 😤😤🙄
I saw a huge one of these in Portugal like 20 years ago
Insane. Now make eye of sauron from this stuff would be cool af.
This would be evil to put directions on
And the mobile phone must be able to withstand that speed.
Great idea for the1984 style screen
stick-figure's packin heat at 2:40, lmao
Thanks. I wish you were my science teacher growing up :)
1:48 a wild Cody sighting! lol
I expected that you can see up and down as well with the word ‘omni’
Was this the same device used in the school room in the video game Riven???
Ok, dumb question: how do you get the two phones to sync up?
How about using very narrow view "spy/privacy filter" in front of rotating screen.. ? Then no cylinder with slit required..
oh lord, they invented IRL Doom sprites
Now do a large size with two 11"+ tablets
or with 150" TVs
I want one now!
Ah, so the phones follow around the shade wheel.
Anyway, isn't it difficult to get two phones in sync? So that one doesn't show the frame 200ms ahead of the other?
I would have thought that it was easier to make one device with two displays to do this..
Anyway, clever way of doing it, hands down.
After seeing this, the first thought that came to my mind is a double slit experiment. I don't know why 🤔
Didn't they put penny operated zoatropes in bars to look at naked ladies?
they didn't last and broke down alot back then
I bet you could do this without moving parts using cylindrical LCD screens as the mask and image screen.
nope. not
So I'm not clear on this, would it be the same effect with just one phone? What is the need for two phones, how does that change the image?
6:35
It would have the same effect with one phone, but to get the same frame rate it would need to spin twice as fast
@@ebbamb Would you still be able to see it 360 degrees around the device or only 180 degrees the phone is facing? I don't really understand how you can see the image all the way around, why it would work when you're looking at the side or back of the phone with the one phone setup.
@@JustMichiganDave whole 360 degrees with one phone and one slit too
How do you charge the phones?
If the cylinder was white would the effect still work?
It's so stupid, but it just works. You could even put a piece of paper instead. How come no one ever think of this before??
You should have done the blackhole from interstellar...
Neat invention!

Let me guess. It's just a screen that spins really fast?

Oh! It's really simple.
Fascinating
like a minecraft item dropped on the ground
Why didn't the inventor not patent the invention?
Couldn’t you technically do this with some sort of compound zoetrope instead of two iPhones in a zoetrope?
I've been watching this guy since I was 11 years old. Im 19 now and he never disappoints. Always has the most fascinating videos to watch
There was no RUclips when I was 19. You kids need to go the fuck outside.
you could argue its 360° but omnidirectional is a little misleading
i cant view it from the top or bottom smh
though that concept makes me think what if you used a tourbillon and a circular screen you could perhaps even render a 3d image with it that has different perspectives depending on where you look from, not quite sure how that would work tho, the spinning pattern would have to be predictable/linked with mechanics and readable by a sensor to determine its current position and it would have to spin faster to make up for the other axis it rotates around
I don’t bet that spinning is good for your phone
This is amazing! Great build, love it 🤗🔥 can you play Doom on it 😅🕹️
How loud is it though?
it is silent, my spinning table was just shaking.
Awesome
Why only 2 phones, why not 3 or 4 or an entire screen shaped like a cylinder or... a sphere.... Hmmmmm
iPads in vehicles should be outlawed.
I can see this being used in AI holo strip clubs in a few years.
andotrope so cool
😂😂 360* Omni would presume above and below 😊
Big Brother is watching you...
We need to get Hatsune Miku on there immediately.
Love the video but you talk at .75 speed
גדול! Great❤
Instead of using a 3-D printer , how about a soup can ? 🙄
Omnidirectional flickering, come on give us more nothing
It's a nice concept, but it won't get very far. The use case is very minimal.
i think it has potential. what if a simple LED strip signboard is placed inside such a setup in the middle of a mall. or any other advertising...
Can you put a person in one?
They would die from the forces due to spinning that fast... but you could :)
