GPU-Powered Planetarium Renders 64MP Projection 108

Posted by timothy from the how-quaint-an-ancient-star-dome dept.
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?

        So, did the planetarium pay the ridiculous "military grade" premium or were they smart enough to find the COTS version?

    • Military Grade is the same as ridiculously expensive items that is hard to maintain and requires special training to operate. Usually only available at universities, military or other government function where money is not an issue when you buy hardware only when talking labor cost. So basically the exact opposite of "Commercial grade".

        Clearly you were not in the military. Military Grade means "GI proof" as in simple and indestructible. That also means its incredibly heavy. So these projectors probably weigh about 500 pounds each and have no controls other than a power switch and no indicators other than"call civilian contractor for service" and possibly a power light.

        The only people harder on equipment than GIs, are the oil field roughnecks. Give those guys a screwdriver, they'll work all day to return a metal pretzel. Its a miracle any oil gets pumped at all.

      Military grade means it's 15 years old, possibly used, costs anywhere from 3 to 100 times what you can get it for on-line, and may no longer be supported by the manufacturer (if that manufacturer is still in business). Oh, if you're lucky they shock mounted it, or at least installed some rails so you can put it in a shock mounted rack ;)

      RS or Farnell sell military grade for many of its components. For the most part its 2-5x more expensive, better MTBF and most importantly a much wider range of usable temperatures and storage temperatures. This matters in many civilian applications where normal components typically are not specified to work below zero (they often do, but don't count on it). Marine environments typically need below zero if you are in the north sea for example. It is easier to use an existing standard that already takes this

      I have two items that touted military grade components. A radar detector and an amp.

      The radar detector has handled the punishing heat of a car window in the desert
      for nearly 9 years now.

      The amp I bought 25 years ago. Still working to spec even though it has seen
      thousands of heat cycles.

      So, maybe nowadays military grade is crap. But at one time, you were assured
      that whatever that item was, it could go to the Antarctica or Death Valley and
      work to spec and not become too brittle to use or melt.

      Electrical specs are also held to greater tolerances. That amp, while every other
      amp's THD varied wildly, held a very respectable number across their lineup.

      It's sad if military grade doesn't mean that any more.

        That sort of military grade still exists, however it's expensive and everything has to be designed or redesgined from the ground up to use it, which can be extremely expensive when you start talking modern computers. So military grade often now means COTS (Commercial Off The Shelf) put into a ruggedized/shock mounted shell and possibly water cooled.
