GPU-Powered Planetarium Renders 64MP Projection
MojoKid writes "The Adler Planetarium has finished a major two-year upgrade project that's replaced the facility's forty year-old Zeiss Mark VI projector with a 'Digital Starball' system designed by Global Immersion Ltd. The new digital system is powered by an array of NVIDIA Quadro GPUs. The specs behind the system are impressive. The 71-foot dome of the Grainger Sky Theater now contains a score of military-grade projectors with an 8kx8k resolution. The final 64 megapixel image is generated by an array of 42 NVIDIA Quadro GPUs and offers an unprecedented degree of real-time modeling horsepower. The planetarium's model of the universe was created in part from high-definition photos captured around the world and via the Hubble telescope."
What's with everything being "military grade" nowadays, from motherboards to video projectors? Is it some kind of fashion, or did US army have a huge sale?
Or do these components actually refer to North Korea's high standards?
Forget magic. Any technology distinguishable from divine power is insufficiently advanced.
... is a military-grade projector, and why would you want one?
OK so scores of Nvidia chips are cool but a Zeiss Mark VI is wayyyy more cool...
... but can it run Crysis?!?
What's next, GPU-powered OpenGL?
I want a planetarium at home. Is there a short throw projector that can fill a reasonable ceiling with a half decent resolution? I can make the assets myself for it, but I'm suprised there isn't more of this done. Movie on the ceiling, maybe, but planetarium for the kids is a very cool piece of kit.
I'll be impressed when it's in 3D. Wait — are they calling 3D without glasses 4D these days? That would be better. No, wait — why don't we just have holodecks already? We've got the tech... http://www.fastcompany.com/blog/cliff-kuang/design-innovation/holograms-you-can-actually-touch
Life is sleep. Death is a dream. Wake up.
I don't get the math....
Is it a score (20) of 8k by 8k projectors, or a score of projectors, totaling 8k by 8k.
And how exactly do you divide 8k x 8k by 20?
8k / 4 = 2k, 8k / 5 = 1.6k, so they have projectors that have a resolution of 2000 x 1600. Impressive if right - vs 1920x1080 projectors.
BSOD!
And my favorite, A device used to simulate the blinking light on the Agena which was used in the Gemini project for rendevous and docking. This was a light with a rotating shutter, who needs 'fancy' electronics.
For what it is worth, I think this is the "overhead projector" that John McCain cited in a presidential debate as a $3 million example of government earmark abuse by Obama. Gosh, it's amazing what ordinary office equipment is capable of these days! It's nice to know the government has absolutely no interest in inspiring and educating children, advancing technology, and attracting tourism.
(By the way, that earmark, and the bill it was attached to, never became law)
Most other countries don't have military grade militaries.
I8-D
Too bad they destroyed the airport, or I'd fly in to see the show.
It's in Chicago. There's so much haze and light pollution here that you can't even see real stars.
this is the infamous $3 million "overhead projector" from the 2008 election.
One of our competitors trademarked the term "hypothesis". From now on, we will call them "boneheaded ideas".
I can hear the little kids on a field trip to the planetarium... "the stars are bright! I can see the Milky Way! Wow, the stars are hot and LOUD..."
I'd have a personalized plate on my car, but "toxic bachelor" won't fit into 7 letters.
Maybe I'm missing something, but 8000x8000 doesn't seem like a terribly impressive resolution, especially stretched across a 71-foot dome (is that radius or diameter? No, I DRTFA, why do you ask?). Hell, my monitor at home's 2048x1152, so this 'amazing' projection system is the equivalent of 8 of my home monitors?
I'd love to update my asteroid discovery movie for this, I've rendered a 4kx4k version for some lesser planetariums, but 8kx8k will mean upgrading my disk storage I think.
I just see a lot of equipment that will break, become obsolete, and have to be maintained more than the previous projector that lasted 40 years.
It sounds cool, but try to replace a video board when one burns out twenty years from now. I'd rather have the Zeiss.
pending committee review
My thought, too...
Hey, might as well let the system do something else during off hours.
Mining Bitcoins would help pay for (at least part of) the whole setup.
A clearer close up view of Uranus. Did you know that Uranus has a gassy atmosphere?

What exactly is a "military-grade" projector?
Are there particularly robust presentations needed for military purposes?
Do the troops in the field need especially high-powered and durable light shone to display movies, or perhaps graphics?
It sounds as impressive as hell, perhaps a giant searchlight mounted on a trundle-carriage like a WWI tank?

Somebody mentioned wanting a planetarium at home. This is very doable. The current version of WorldWide Telescope:
http://www.worldwidetelescope.org/
supports a very straightforward remapping onto a dome through multiple projectors (don't know about the military grade nonsense). There's a calibration screen that handles all the geometry. Just need some baffling to minimize the overlap between projectors.
Navigating through the Sloan galaxies is very impressive on a planetarium dome. WWT also displays a half million objects in the asteroid belt, Kuiper belt, etc in real-time (or in accelerated motion) using that space-age GPU technology. (Of course, "real-time" is another overused buzzword.)
Supports Kinect controls for the game addicts.
Neat - anyone been to the show yet? I'd love to see a first hand report - it will be a while before I can get down there myself.
I'm sure they put on some great shows, but these modern "overhead projectors" often lack the dynamic range of the best discrete planetarium projectors out there.
Even among dedicated planetarium projectors, only the best are able to replicate the differences in brightness between mag 1 and mag 6 stars with any convincing accuracy. Many of them project such a "flat" sky in terms of brightness that it's difficult to recognize even familiar constellations. The old Morrison Planetarium projector had dedicated lamps for particular bright guide stars, and the projector at Chabot Science Center is very good at that.
It's discouraging to see a run-of-the-mill college planetarium with "bright" stars that are just smears of bigger dots.
So they aren't pixelating, but I bet their Spica is nearly the same brightness as their Porrima.
