What 3D Sources Work?

A single Mirage projector can display 3D (stereographic) images as described below.
Such images require a specialized source, as well as additional hardware and software
in order to be displayed and interpreted correctly in a typical 3D active stereo viewing
environment.
'
In simple terms, images generated from a 3D-video source consist of a series of
images (frames or fields) that alternate quickly between two slightly different
viewpoints corresponding to the separation of our left and right eyes. When these
frames are displayed with enough speed and viewed with special glasses synchronized
with the left/right frames, the resulting "single" perceived image appears with much
the same depth and perspective we sense in the real world.
'
Once you have the necessary source and hardware/software setups described below,
the Mirage projector will detect and process a 3D (stereographic) signal
automatically.
In addition, if you are using Christie's 3D Stereo Sync Cable (available early 2005),
select the appropriate "3D Stereo Sync" setting in the Advanced Image Settings menu.
See 3.5, Adjusting the Image for more information.
NOTE: Christie's Stereo3D
2000/4000/5000/6000 models is not compatible with Mirage S+ models.

A 3D-video signal is sent to the projector via analog cables such as:
• 3-wire RGB sync-on-green
• 4-wire RGB with composite sync
• 5-wire RGB with separate H-sync and V-sync
• DVI
NOTE: Refer to 2.3, Connecting Sources for full details and illustrations.
Most 3D (stereographic) signal formats currently available are optimized for display
via CRT (cathode ray tube) technology, thus they have high pixel rates unsuitable for
use in Mirage. However, by reducing the blanking in these signals, you can lower
their pixel rate enough to be compatible with the projector (under 220 MHz).
