[ Anaglyph vs 3d glasses ] Wich is the real diference ???
Hello to all, in last 3 years i play the games with 3d stereo driver and my anaglyph goggles (red-blue glasses of plastic - cardboard, i obtain in theater cinema show of 3d movies as spy kids 3d).

Really the diference to play with my anaglyph (red-blue glasses of plastic) compare with real 3d glasses is high or not justify buy real glasses ?

Thank you.

There are some pro's and con's of shutter glasses. I assume you are refering to shutter glasses when you say real 3d glasses?

First of all, shutter glasses only work with CRT monitors and on some DLP projectors. In some games, you get occational blinks or white flashes at random times. But the colors, ghosting and overall image quality is much better than anaglyph glasses.

Anaglyph glasses work with LCD technology, but they suffer from worse ghosting than shutter glasses. You really need to tweak the colors and stuff of an LCD display to minimize the ghosting that occurs. But you can get it to a decent level.

I got my shutter glasses back in 2000 and used them exclusively until I got an LCD projector. If I was able to use shutter glasses with my projector I would definately go with that option over anaglyph.

But as it is now, I have to choose between a 21" CRT display and shutter glasses, or a 90" screen, LCD projector and anaglyph glasses, and between the two I choose anaglyph with large screen.

Linus

Linus - I have the red/cyan glasses from www.anachrome.com and have been experimenting with the settings, but still get a lot of ghosting (dependent on the game). Could you give any more details/tips on how you've reduced your ghosting? This could be a really useful resource for those of us who have moved to anaglyph after many years with CRTs and shutter glasses!

Cheers

I first calibrated my LCD projector using Avia and DVE (Digital Video Essentials) to get the correct color balance for watching DVD movies. I used the Nvidia Purevideo MPEG2 decoder when doing that as that uses hardware stuff on the Nvidia card itself to render the picture. It is also important not to use overlay mode when playing the DVD used to calibrate as that freaks up a lot of things that makes it impossible to calibrate correctly. I don't know why that is but it is very obvious as some of the patterns used for calibration just don't work as they are intended to do. So, use Media Player Classic and Nvidia Decoder. Set Media Player Classic to used VMR9 (renderless) mode for output and use the DVD to calibrate color balance, contrast and black-levels.

Some games work better than others though in terms of ghosting. Blue and red colors are hard to produce as those colors are used to get stereo separation. An example of a game that works really well is Flatout 2. Download a demo of that and give it a try.

I also got a bunch of different 3d glasses, including the anachrome ones. I have found that the anachrome glasses are the ones that works the best actually. They have a good balance between color reproduction and ghosting.

What I would like to find though is a better way of doing color calibration to fit the right and left eye lenses than the DVD I've been using. Would be great to find something where you close your left eye and adjust whatever until something blends into the background and then do it for the right as well. I've been searching for something like that but not found any yet.

There is however a huge difference in how much ghosting you get depending on settings like hue and saturation on my projector, but the best settings I have acheived so far is color calibration using the DVD.

What I would have hoped for is that Nvidia providied a halfcolor-mode for anaglyph encoding. It is a method used to reduce the problems of depicting red and blue colors for anaglyph. There is a thread about it here:

And some examples of the result here:

[url="http://mitglied.lycos.de/stereo3d/anaglyphcomparison.htm"]http://mitglied.lycos.de/stereo3d/anaglyphcomparison.htm[/url]

I also think it is something you get more used to after a while of using anaglyph glasses. It takes a while to get used to that the red filtered eye gets much less light than the cyan filtered eye. It also helps to turn up the gamma setting in the stereo drivers to about 1.5.

I think that's about it so far that I've noticed when using anaglyph. I really hope Nvidia implements halfcolor mode or optimized mode anaglyph as I think it would improve the viewing experience quite a bit.

There is a difference, but for most purposes the anaglyph glasses are great. And it may be safer to use them than the shutter glasses. I personally use them for creating and watching of 3D photos and 3D movies (as you may see eg. [url="http://www.3djournal.com/)"]http://www.3djournal.com/)[/url] and it is OK.

Hi

I would pay 500$ for shutter glasses, but (lucky me /smile2.gif' class='bbc_emoticon' alt=':))' /> mine only cost 70$ (eDimensional). Worth every $. Not all games work in 3D though.
