The event began with a chance to learn about the three major approaches to full-colour 3D display today, and a chance to try out a couple of them. They are:
- Active LCD shutter glasses darken one eye, then the other, in sync with the alternating image being shown on a standard display. This halves the effective frame rate by sharing the display across both eyes, and being an active system requires power to operate the shutters and also to be in sync with the display. Expensive glasses, but off-the-shelf (though high-end) screens or projectors. [more on wikipedia]
- Passive polarised glasses work much like the old red and green glasses, but using polarised filters rather than red/green means you get a full colour experience. It means cheap, passive glasses but complicated and expensive screens and projectors. If you’ve seen a colour 3D movie, this was probably the way it was delivered. [more on wikipedia]
- Autostereoscopic display is a stupid name for a screen which displays 3D without needing glasses by use of a lenticular or ‘parallax barrier’ layer in front of a specialised (usually LCD) display, presenting a different image based on viewing position. No glasses, but a very limited viewing angle. [more on wikipedia] (via 3D TV - Roo Reynolds)
