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

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.
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.
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.
There is a reason it hasn't been used before. First, you're losing a huge percentage of your light because of the slits so the display needs to be correspondingly brighter (contrast may be affected too) plus when do you actually want to watch a cylinder of video? You can't make it much wider without starting to get dangerous/expensive so you basically have a gimmick that might be useful for an advertisement in the airport or at night in vegas (not outside where it would be too bright). But neat video.
I was skeptical but after a little thought I think you would win that wager. The maximum image size may be reduced and further one would could correct the image for distortions.
reminds me of how they did trees and other things in older video games. It wasn't a tree, it was just a picture of a tree that always faced the player.
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 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.
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.
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
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?
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.
But hold up...doesnt that mean you can just make a 3D camera and take 3D video with 1 camera lens that spins in place of the screen setup you have now? I mean obviously it would take some more engineering...but, it might be an interesting project..
It would be difficult to make, but probably. How 360° cameras work now is taking photos from different lenses and stitching them together. Doing it in a similar way to this video, there would probably be problems with motion blur, and it would still have blind spots above and below it. I don’t know if the technology currently exists to solve those issues or any others that might come up, but I’m sure it could be figured out by someone.
no i don't think so. for three dimensional image or video you need to capture the scene from different angles.. spinning single lens camera at one point wont capture the same part of the scene from different angles.
@@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.
This is the future technology the 80s promised me
Well said.
Amen
Still waiting for my hoverboard thou
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!"

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
Probably cheaper to have a clone pin you down and make you stay still and watch like a good consumer should.
@@maxave7448 - Would it be difficult to put it in partial vacuum? It shouldn't cost much to maintain momentum without air resistance. (and magnetic bearings?) For a permanent, fixed display, that doesn't seem too expensive -- especially considering the high novelty provided.
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.

This is like looking at a 2d picture that is always facing the player in a 3d game
u mean vision pro?
Correct if you ever played doom
Crazy how he made it look like the viewer from Riven
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
I think it was a brilliant artistic choice. You've got to stop people from touching the spinning bits anyway, so why not do it in style?
Perfect for when you need to binge and spin at the same time.
Nah this is borderline witchcraft
There's no such thing as witchcraft stop watching stupid movies like The Craft.
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.
Perhaps try a wireless PC monitor, put it on top or below and use peppers ghost reflector which is what spins
One step closer to "Help me Obi-Wan Kenobi, you're my only hope!"
It's like trees in old video games where it's just a sprite always facing the player.
That is quite cool. I might try making a small digital clock this way.
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
as soon as i saw it in action, the lines artifacts and the noise instantly gave away how it works.

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'.
This helps us play Doom in real life.
very good pick! simplicity is the best
Mike Andos is about to become a very rich person!
I bet you could do this without moving parts using cylindrical LCD screens as the mask and image screen.
nope. not
@@SomeBeautyfulArt I am exasperated by the exuberance of your perspicacity.
I was skeptical but after a little thought I think you would win that wager. The maximum image size may be reduced and further one would could correct the image for distortions.
Always a great vid
You haven't even watched the whole thing!

So much easier than getting two monitors and running around in circles all day to get the same effect like I've been doing for years.
stick-figure's packin heat at 2:40, lmao
I hope the inventor gets rich off this! This is awesome.
Will be used everywhere: For advertising.
yes this simple device has potential....
Since it's very fitting for the flat sprite style: can it run Doom?
You always have the coolest videos.
This is an effect that truly looks edited in, trippy
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.
I saw a huge one of these in Portugal like 20 years ago
This can be used in many places. Surely something that can change the world, for better or/and worse.
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
It’s like the sprites in Doom. Tor record without flickering, just lower the ambient light.
I want one now!
I could see being welcomed to city 17 with dr. breen's face on this.
Thanks. I wish you were my science teacher growing up :)
Again, watching before the Mark Rober vid! Realized you live down the street from me!
4:15 surprisingly I even though about hollow mask after seeing the thumbnail
Great idea, but I think it will be very inpratical with 72" tv's, although you don't need your ceilingfan anymore
They had a bunch of these at the Metallica concert I went to.
Insane. Now make eye of sauron from this stuff would be cool af.
Great idea for the1984 style screen
If I had one of those, I could have my own A.I. companion with an avatar.
“If you had surround vid, you could see the naked Asari standing right behind me, because real-life surrounds you.”
It's like these old 3D videogames with sprites lol

Turns out the monsters in Duke nuke were just advanced technology.
Wow you really got that 1993 hairstyle down. 😂
"Screens are everywhere..." No they're not. There aren't any screens in my elbows, so that proves it
Finally. Noone will escape rickroll.
oh lord, they invented IRL Doom sprites
Good editing 😤😤🙄
DO A BIG ONE WITH FULL SIZED TVs!!!!!!
reminds me of the mechanical TV
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
I am thinking of the magic tricks that can be done with this.
It would be funny if you told the time at the airport scene.
🎶It always feels like somebody's wAAATCHin meeEe🎶
And the mobile phone must be able to withstand that speed.
Great, now my boss can catch me slacking off in 360.
Maybe get a skilled trade instead of a fucking boring-ass desk job.
After seeing this, the first thought that came to my mind is a double slit experiment. I don't know why 🤔
How do you charge the phones?

Only omnidirectional in one plane

"I GOT 2 PHONES 🗣💯📱📱"
2:03 is that the thing from Myst or Riven?
Didn't they put penny operated zoatropes in bars to look at naked ladies?
they didn't last and broke down alot back then
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

Ok, dumb question: how do you get the two phones to sync up?
Cool, Can you make it bigger
Oh! It's really simple.
This would be evil to put directions on
You should have done the blackhole from interstellar...
How about using very narrow view "spy/privacy filter" in front of rotating screen.. ? Then no cylinder with slit required..
Was this the same device used in the school room in the video game Riven???
