The Technology Behind the New Las Vegas Sphere (cnn.com) 71

Posted by EditorDavid from the theatre-in-the-round dept.
The world's largest spherical structure "squats on the Las Vegas skyline like an enormous spaceship, black and mysterious," reports CNN, "until night falls, when it will glow like the Earth from space."

The $2 billion arena — called "The Sphere" — was built just east of the Venetian hotel/casino. It's 366 feet tall and 516 feet wide (or 111 meters tall and 157 meters wide) — and it boasts the world's highest-resolution wraparound LED screen: Its exterior is fitted with 1.2 million hockey puck-sized LEDs that can be programmed to flash dynamic imagery on a massive scale — again, reportedly the world's largest... The acts onstage will be dwarfed by the towering 16K LED screen, which wraps over and around much of the audience.
It was fully illuminated for the first time on Tuesday to celebrate the Fourth of July, CNN points out (offering some video footage). When it opens in September, the plan is to light up its exterior with animations every day and night.

Slashdot reader Tony Isaac says the news "got me wondering how they got such great video on the curved surface of the sphere." It turns out there's a whole lot more than just the exterior that breaks new ground in audio and video technology. An older IBC article goes into detail about how they accomplished both the exterior and interior screens, and the high-resolution audio inside.
CNN reports: Rich Claffey, Sphere's chief operations officer, says that more than 160,000 speakers spread around the bowl will deliver the same pristine sound to every seat, whether someone is in the top row or down on the floor. The venue also is equipped with haptic seats that can vibrate to match whatever is happening onscreen — an earthquake, for example — and 4D machines that can create wind, temperature and even scent effects.

"The way I describe it to my friends and family is, it's the entertainment venue of the future," Claffey says. If it all sounds a little over the top, well — this is Vegas.
The arena's first act will be 25 concerts by U2 (with tickets starting at $140). "There's nothing like it. It's light years ahead of everything that's out there," says U2's The Edge during a tour of the venue in a recent Apple Music video...

And U2's Bono adds that "Most music venues are sports venues. They're built for sports — they're not built for music. They're not built for art. This building was built for immersive experiences in cinema and performance... "

    Much like everything else in Las Vegas, it's a waste of resources and human ingenuity. It will be underutilized, and eventually (fairly soon in building terms) subject to poor maintenance, decay, abandonment (when the owners go bankrupt) and then, one day in the not-too-distant future, will be demolished with little to remind of it.

    Meanwhile, Las Vegas still is an unsustainable depressing poor slum (anywhere outside the "strip") in the middle of waterless desert, trying way too hard to make a show of being a fun and attractive place.

        I assume you're being flippant, but FWIW U2 has a long history of multimedia (and mixed-media) experimentation. Their early '90s ZooTV tour (which I saw in person) really was kind of groundbreaking for the time. And they're not afraid to take advantage of things beyond simply enhanced audio tech.

        "A U2 concert" wasn't exactly at the top of my list generally, but I'm interested in seeing what they do with this specifically and might try to attend.

      They spent $2 billion creating the thing. I think they'll spend the five dollars to keep it maintained.

      That said, having been to Vegas (once), my thoughts turned to two things. First, how much electricity is this thing using? I don't care if they are LEDs. You put enough of them together and they will use a chunk of electricity. And certainly the inside, with its lighting and sound system, to name just two items, uses a buttload of

If you do it during the day you'll get to see a bonus, even larger spherical structure in the sky which is lit up so brightly you should not look at it directly and at night you may get to see a smaller spherical structure in the sky instead.

      Las Vegas got the idea that it wanted to be "family friendly", and so built shows in front of the hotels such as the pirate ship battle, got the Star Trek hotel running, and so on. The theory was that the family could be entertained while you went out and gambled.

      Over several years this idea languished because, on balance, no one wants to bring the family to Las Vegas - that wasn't something that people really wanted to do. That's not to say that there weren't impressive things to see or that no one brought their families along, it just wasn't as broadly popular as (for example) Disney.

      I'm not saying that you're wrong, only that there was an underlying reason that previous LV languished and decayed the way it did. Those same reasons don't apply to LV of the present, including the sphere, and so it might work out OK.

      One thing about LV that I really like is the shows. Any show - even from a 2nd tier hotel - will be excellent quality and highly entertaining, for the simple reason that a bad show doesn't last long in LV.

      A tip for getting into shows: If you want to see a show, go to the hotel ticket counter on the day of the show you want and ask if there are any cancellations. There's usually 2 or three of these for any showing, and you can usually get good seats for a discount with no hassle (ticketmaster) by simply showing up and asking. I've done that for numerous high-profile shows.

        Aside from the casinos (and all the shows/restaurants/etc they've incorporated to draw in guests) there are basically two reasons anyone visits Vegas:

        1) There's a concert or sporting event you want to see. Usually, those are more popular among people with no kids, or you leave the kids at home and enjoy a parents' weekend out.

      Yes, it will eventually decay. Until that time, it rejuvenates the interest in the area, will bring lots of new tourists, and they have sold out events with tickets going as far as over $500 per seat.

      (Even if the average is $200, they only need to sell 10 million tickets to make up. 18,000 seat capacity, assume 30% utilization, and it pays for itself in 10 years).

    When I was a kid in the '60s my Jewish grandparents loved to go to Las Vegas. They were tight with their money since it didn't come easy for them and they were very disciplined about not gambling more than they could afford. What they loved, as did everyone else who traveled there from smalltown USA, was the sense of flashy elegance and mere presence of money and superficial sophistication. Prostitution back then wasn't legal (still isn't in the cities) but there were plenty of "sin city" attractions that you you couldn't take anyone under 21 to. To this day I don't know if my grandparents were into any of that.

    Back then the hotels had a regular practice of paging celebrities over the casino floors. "Bart Starr you have a phone call." "Mister Sinatra you have a message at the front desk." All complete bullshit but the guests ate it up. It made them feel closer to the elites than they ever otherwise could be.

    What also attracted the generation that lived through the Depression and WW II was how cheap the rooms and the food was. The business model subsidized everything through casino profits. You could have a real nice breakfast with the kids for $1.

    Sometimes they would take their grandkids. Back then there was literally nothing for a kid to do other than sit by the pool all day. The hotel might have a little arcade with pin-ball machines but that was a wan experience next to the flash of the casino floor. They took the rules of no-kids there very seriously. If you wandered three feet over the line for more then 10 seconds you would have some casino dick right on top of you.

    All different these days. After the '70s were thankfully over Vegas declined and that continued into the '90s. They determined that gambling could not be their 80% profit center. Gambling was becoming legal in many states and it wasn't enough to attract the kind of money they wanted. They started to invest in other kinds of entertainment and also made it family entertainment. Roller coasters. Water slides. Shows for kids. Sigfried and Roy. Marine life attractions (in the middle of the desert.) Star Trek. The Stupak Tower. On and on. But the all-you-can-eat $2 buffets were gone, as were the $25/night rooms.

    If there was any one constant to entrepreneurship in Vegas it is that it is a never-ending exercise in one-upmanship. More rooms. Bigger pool! Best asses! (Seriously: Riviera) Most powerful lightbulb! (Yeah that's the Luxor hotel). Anything at all to get attention and to be the "best" at something. Anything.

    So this Sphere thing is nothing more than then next step in that. It doesn't surprise me. I appreciate the engineering and the willingness to push the edge in tech. It isn't a waste, any more than defense spending is a waste, and it is done with private funds and employs a lot of people. It will be fun to go see, but hardly newsworthy.

    • There aren't a lot of theater-centric locations which have significant money behind them in the US. Broadway, Vegas, Branson, Missouri. That's about it. Yes the gambling doesn't pay for it anymore, not all of it anyway, but it can be worth the high ticket price for a unique experience.
  • Miniaturize this to make a globe that I can afford to buy. Then the control computer can be programmed to display all manner of interesting global data graphically. Political entities, global weather, time-series trend videos about many things, etc. etc. etc, How cool would that be?

  • Even if the band was something I like and not U2, $140 for a couple of hours of lower quality music surrounded by a bunch screaming idiots is way too much.
