Projector behind the dome
At the time of writing Christie had recently released a new HD (1920x1080) DLP projector capable of frame multiplexed stereoscopic projection. This is traditionally been problematic at this resolution, namely driving an HD resolution signal at 120Hz. The more common way people achieve HD resolution stereoscopic projection is employing dual projectors using either passive polaroid filters or Infitec. The approach taken with the Christie HD3 is that one only drives it with a 60Hz HD signal (either DVI or analog), the projector internally multiplexes that video image to create the 120Hz stereoscopic sequence.
Not only is this a HD stereoscopic display but it is also an immersive environment, namely stereoscopic dome projection. At the time of writing the only card from Apple able to be used for frame sequential stereo is the nVidia fx4500 (the emitter port to synchronise the active glasses is required).
