Stereo Scopic 3D - How can it be done?

[Aruna]

The short answer:
No.

The long answer :
The glasses used when viewing Beowulf are polarized, which means that each lense only accepts a certain wavelength of light. In the theatre, they accomplish this by using two projectors which projects two images on the screen, both polarized differently. Unfortunately, your regular computer monitor can only project one version of light. In order to overcome this limitation, lots of different manufacturers have created workarounds, such as the old school shutter glasses, and the low tech anaglyph glasses. The only way to view your images on a regular computer monitor is to use anaglyph glasses, and render out your images that way. If you don't know what anaglyph is, here's a wikipedia entry (http://en.wikipedia.org/wiki/Anaglyph_image). There have been strides in 3D projection on special LCD monitors, of which several were shown at Siggraph 07 last year that look really promising. It's still a novelty for home computers, but is making strides in feature films to get more people back into the theatre.

Ok Thanks for the answer. I will put my 3D glasses on Ebay for sale now if anyone is interested

Thats exactly the first thing I thought after seeing the film too.. hence why I find myself searching for an answer here. Shame :( could imagine it being one hell of an awesome technical addition to the games industry

There are three ways you can see 3D on your computer. Anglyph is the easist and can be done in photoshop by combining the red channel from a left eye image and using that to replace the red in the right eye image. You can also use cross eye and free view methods by crossing your eyes when viewing side by side right image on the left of the screen and the left image on your right. Or you can do the oppisite for freeview, although I find that method to be the most difficult to resolve.

Depending on where you saw Beowulf your glasses can be re-used for the same system (Real-D or Dolby 3D, or IMAX) Imax uses normal polorized lens, and are the most common. Read-D uses polarization too but uses a method called circular polarization which produces less ghosting. Dolby 3D uses a color filter wheel and glasses to produce the 3D without a silver screen.

actually you could get some kind of 3d perception going on very low-tech.. Dali painted alot of stereoscopics and the same can be done with 2 computer screens (or tv's) and mirrors.. what you need is 2 slightly offset renders (for both eyes obviously) and separate monitors for them both. you then separate your eyes with the mirrors to see the images/sequence.. it's a bit of a set-up.. but it's the same principle as the polarized glasses, and less expensive.. I don't know if I explained it right, so I think I'll add a bit of a sketch later..

Edit: attached the sketch.. hope it's clear enough
