Comparison of 3d Anaglyph Glasses / Methods
Three different types of 3d anaglyph methods are compared in this video I created using a raytracer I wrote many years ago. The three methods are: red/blue glasses, magenta/green glasses, and yellow/blue glasses. Each method is about 34 seconds long, so you won’t have to wait long to get to your glasses.

For me the red-cyan anaglyphs (not? necessarily red-blue, you can retain some color with red-cyan while red-blue is purely greyscale) work best.
The magenta-green ones seem to produce more pronounced ghosting.
The yellow-blue (colorcode3d) are not bad in regards to ghosting and color retention, but they have so large an intensity difference from one eye to the other that I find them very tiresome to use.
@nuclearthelab Actually, I thought of putting the phrase “Results may vary” in the video
but I decided not to. This is especially the case since my eyesight isn’t the best (I’m not sure how much this would skew the results). BTW, I use the term red/blue because that was what they were traditionally called, but? of course, it is really cyan. I try to stay away from keeping the color (of the original scene) in (you’ve probably seen some of my other videos where …
@nuclearthelab …I keep the color in,? though) because of concern of the glasses color appearing in the scene originally and screwing up the effect (i.e. red and cyan being in the scene before conversion to red/cyan anaglyph). Have you noticed this to be a problem in other videos?
BTW, when creating 3d anaglyphs in the past, I noticed that the ghosting can be reduced by changing the brightness of the left and right images before conversion to anaglyphs. Sadly though, this …
@nuclearthelab … tends to reduce the noticeability of the 3d? effect.

(sorry about the 3 part reply… I don’t know why they have a character limit
Yes generally bright colors are bad because they tend to produce ghosting, and colors near to the color of the anaglyph? filters are the worst as they make objects completely dissapear from one eye (which I find very anoying and can’t stand to look at for more than a few seconds). For this reason I generally desaturate the colors a bit before making the anaglyph image, but not wipe them out completely.
Still the best results are obtained by using other stereoscopic methods such as shutter glasses. I’ve recently? made a circuit that drives cheap shutter glasses I bought on ebay, using the VSYNC VGA signal. I’ve also written a program called “stereowrap” (it’s on googlecode hosting) which can be used to make any stereo OpenGL program produce sequential vsync-ed stereo pairs suitable for my circuit (it can also produce anaglyphs automatically). I find that whole stereo setup much more satisfying.
@nuclearthelab That’s an interesting idea – desaturate – keep? some amount of color while somewhat avoiding the problems mentioned before.
@nuclearthelab Yeah, shutter glasses would be much better. When I first heard of 3d TVs, I didn’t know how they were going to implement it (logistically speaking), but then I heard that the TV sends out a wireless signal to the glasses to tell them when to switch left/right. ? That’s a perfect solution.
If I ever get a pair of shutter glasses, I’ll have to try your VSYNC solution.
