Las Vegas' dystopia-sphere, powered by 150 Nvidia GPUs and drawing up to 28,000,000 watts, is both a testament to the hubris of humanity and an admittedly impressive technical feat | PC Gamer (www.pcgamer.com)

Wikipedia says it's 16,000x16,000 (which is way less than I thought). The way the math works, that's 16x as big as a 4k monitor, so 16 GPUs would make sense. And there's a screen inside and one outside, so double that. But I also can't figure out why it needs five times that. Redundancy? Poor optimization? I dunno.

But wouldn't that be only necessary if it needed to render real-time graphics at such a scale? If I'm correct, all its doing is playing back videos.

[–] ilinamorato@lemmy.world 5 points 4 months ago

I think it's doing some non-trivial amount of rendering, since it's often syncing graphics with music played live.

Live audio visualization in game engines is definitely a thing ex. https://youtu.be/IZL7VAt97ws?si=H74SwrLZYfsYNTY8

Even if it's just playing back videos, it still should compensate for the distortion of the spherical display. That's a "simple" 3d transformation, but with the amount of pixels, coordinating between the GPUs and some redundancy, it doesn't seem like an excessive amount of computing power. The whole thing is still an impressive excess though...

I work for a digital display company, and it is definitely redundancy. There will be at least two redundant display systems that go to the modules separately so they can switch between them to solve issues. If a component fails on one side they just switch to the other.

Ah, nice. Thank you for bringing your expertise to my nonsense.
