I saw this on the other place earlier. Apparently the whole thing is rendered in Blender.

Given the difficulty of creating this in reality... in fact would it be actually possible to achieve this through a real moving train window?! Maybe, but you'd probably need a 1km length of images for that short clip alone. Anyhow, seemed obvious to me it was cgi. Neat though.
Ps 'Llamatron', nice choice :)
I have seen a real version of this. It was made using LCD screens in a tunnel. Displayed advertisements as you went by.
Oh cool, I guess some modification of the zoetrope mechanics is necessary
Only in cameras.
One could paint stripes in tunnels lit by cheap LED or sodium vapor lamps (that flicker at 100/120 Hz) that appear stationary at the speed limit. I wonder how drivers would react.
I've seen this in Vancouver, Canada, between Burrard and Granville station. unfortunately they're used to display advertisements. The trains don't have drivers and are controlled remotely from a central location.
That's very much not what I meant. These stripes would be passive (just paint) and you couldn't really customize them because sodium or unsmoothed LED lights' flicker has a 50% or greater duty cycle, blurring any design beyond recognition.
What you're referring to are persistance-of-vision ad displays around passing trains in tunnels. These require active electronics and even accurately measuring the train's speeds.
The system in Vancouver does use electronics to create the flashing, but I'm pretty sure it just synchronises to to average speed of the train because the illusion is quite inconsistent. It will almost always scroll forwards or backwards from the rider's perspective. It probably does help that the sky train speed is controlled by a computer, leading to more consistent results.
Yup, Prague's system I know is the same as Vancouver's, possibly by the same company, but I've never seen it sync badly. The system I'm proposing are simple painted stripes, the flashing is the nature of existing lighting.
I wonder how physically resilient the LED bars in Prague are, since the windows can open enough for someone to extend a stick to damage them.
They did this in San Francisco several years ago as well! It was a neat proof of concept but it didn’t stick around super long.
Especially not if the trains have windows that open slightly like Prague's, allowing someone to just extend a cane and destroy the whole installation.
Badly I would assume
There is (or was, i think it's still there) one of these in the subway system in NYC
OH SHIT! Videos can play on Lemmy now?!
Only direct links(.mp4, ...etc).
Else they show as embedded(YouTube , Odysee ...etc) on the web and show as links on other Lemmy clients.
Reddthat has had support for ~40MB videos for the longest time too. But because of how all the clients work (like you've said) videos nearly always "perform" worse.
In saying that, video support only landed in Jerboa in a recent update so now might be a better "engagement" for video content
Short-form videos auto-playing is literally the only thing I miss from other platforms.
Brilliant, I love it
Zoetropes are coooool!
I'm not scientist, but that guy is running pretty fast.
