Here are some of the photos that were taken at Siggraph 2013...
Above: The next morning, Autodesk bussed us to a New Orleans-themed restaurant in Disneyland. Much to my surprise, the food was excellent.
Above: The Siggraph exhibition floor opens, and here is Christie's turnkey CAVE-like Holostation running four digital projectors -- and sized to fit a regular office building elevator. $300,000 or so for the shared 3D experience.
Above: Also in the Christie booth, one of their theatre-grade projectors blasting out real-time 3D animations in 4K resolution at 120 frames per second. Siggraph visitor dons a pair of polarizing glasses for scale.
Above: In the Vicon booth, their hand controller (lower left), polarizing glasses (at right), and three infrared camera-sensors (along the top). The balls at the end of the sticks are covered with light sensitive coating, with which the infrared cameras detect motion.
Above: But over in the Leonar3Do booth, the same thing at a fraction of the price. Their bird-like hand controller is held like an airbrush.
NVidia and AMD competed with each other by holding invitation-only parties on the same night. Savvy media first took in the NVidia dance-floor party first (above) and then alter hiked over to AMD's sit-down dinner (below).
