Alioscopy Demonstrates ‘No-Glasses’ 3D Display at IBC
by Ramin Zahed

San Diego-based 3D visualization technology provider Alioscopy will join Autodesk in Amsterdam, Netherlands for IBC 2009 (Booth No. 7.D21). The company will showcase its finished autostereoscopic 3D content playing on a proprietary HD LCD display, and will outline how artists and technical directors can use various editions of Autodesk Media & Entertainment software to create and composite autostereoscopic 3D computer generated content for play-back on Alioscopy LCD displays.

Has anyone seen a Alioscopy screen yet? It would require alot of GPU power to work in games, but sounds like it works well? (6 views?)
Make up your own opinions, don't believe B.S! Especally when its about a human and spread with the intent of ruing that persons life.

3D is the Future of Viewing Tech, you see in 3D naturally so how can it not be something you want on your screens?!

I haven't seen one but from what I heard they are not really suitable for gaming. First off the resolution is severely crippled, viewing angles are very low and image quality may not be very sharp. Not to mention the overhead of having a 3D driver render 6+ viewpoints every frame. Similarly they are not much use for 3D movies since those are all shot with a 2 camera process. So they are really only for use in the advertisement sector mostly. Any professional users (medical, scientific) would not be willing to sacrifice quality like that and I doubt gamers would accept that either. Still, I'd like to see how this technology progresses.

They claim that the interleaving isn't bad on the offical site. I dont understand how this would be the case though, hence asking if anyone had seen the display in action.

Looks like this will be a complete fail of a company. Although 6 views wouldn't be such a issue for a Quad-SLI machine?

Is there a reason why you can't you just render 2 views and copy them to get 6 views (3 times the same left view and 3 times the same right view)?

That would defeat the whole purpose of the display. It wouldn't work at all. The point of having the extra views is so when you move your head the image stays in 3D (otherwise the viewing angles would be dreadfully small). However if you just duplicated 2 views like LRLRLR then if you moved your head just to one side a little then the eyes would swap (you'd get the left signal on the right eye and vice-versa). So it needs all the views.

According to the comments this more or less seems to be the same principle as philips wowvx? These displays are suppoused to give a more holographic image even when moving while stereoscopy "only" gives two different images to the eyes.
The Philips "giving up" on their 3d-displays means nothing for the stereoscopic audience in general since it seems to be two more or less totally different technologies. Philips or Alioscopy simply aren't suitable for stereoscopic gaming because of the processing power needed. At least not yet. The stereoscopy we're used to is another thing though! :D

I've seen many alioscopy screens and prints at Dimension 3 expo.
They're pretty much like auto-stereo postcards but with moving images.

The resolution is poor, not 2D//3D switchable (the lenticular filter is always on), there was no realtime/film/game content displayed (only pre-rendered CG or pictures).
It works but badly, the issue is not view angle because the lenticular effect repeats itself in space, there are regular bad angles (precise angles at which it doesn't work). but the main issue for me is the huge ghosting, you basically always see at least 2 images if not 3 images. It makes the image blurry, the more you look away from the screen plane the more blur.

One of the prints was much bigger and had a much much finer lenticular filter, it was much better, at least the object in focus at screen depth is a little sharp.
It was ideal for portraits or probably advertizing with a sharp subject on a blurry background (i saw an autostereo ad at a bus stop in Bristol (uk)). But i would never want that TV in my living room.

Auto-stereo will need a breakthrough to rival current stereo solutions, otherwise it will never reach the home market.
