3d Anaglyph Filter Kmplayer Download For 92
Rachal Langwith
I ve been exploring 3d photography lately and also enjoy watching 3d movies. I dont have a 3dtv (yet) so I ve tried all other techniques , parallel, crosseyed, VR (Google cardboad) and anaglyph.
The easier for most people to view in 3d is of course anaglyph and the most popular is the standard RED/CYAN format which allows some colour to be visible in the final photo and is relatively comfortable especially in the dubois method (Developed by Eric Dubois) that minimizes retinal rivalry.
What about the most recent anaglyph formats like:
GREEN/MAGENTA (also marketed as trioscopics): A few movies were released with this format (Coraline, My bloody valentine) and some games (Batman arkham asylum). Wikipedia says that it allows more colour through, especially orange than the classic R/C.
AMBER/BLUE (or yellow/blue, patented as Colorcode 3d): They tried a lot to promote this format as the new anaglyph standard during a superbowl game (in 2009 I think) with an episode of chuck and a couple of movie trailer. The company claims that left amber filter allows almost all color information to be viewed. People say that its a lot darker because of the dark blue right filter.
Personally I have only tried the classic R/C glasses but have been experimenting with BINO player and found the following interesing results.
The half-colour view with green/magenta glasses offers amazing colours ... very warm but I dont really know if you can actually see them through the glasses?
The dubois view is actually the most comfortable and I have found that the colours you see on screen without glasses are almost exacly the colours you see with the glasses on. If thats the case then with the Amber/Yellow format seen with dubois the image is almost similar to the original.
I have ordered a pair of Amber/Blue to try myself. I include a comparison image i made with different versions rendered in the free software Bino player.
I got no problem with cross eyes technique. I even learned parallel viewing which is quite comfortable looking pictures on a phone that way!
Still for extended periods of 3d watching anaglyph is a better choice. Like if you want to watch a full movie. Thats why I am asking if any other anaglyph method is superior to classic red/cyan or are just clever marketing.
Ultimately, it is the hassle of wearing glasses which restricts the popularity of 3D. But at the same time, not many people succeed in naked eye viewing, mostly due to them giving up before they succeed.
Glasses-free tvs are coming in the next 5 years. Many companies have shown prototypes. The have limited hotspots right now but its getting better.
I think the most comfortable tech now is passive 3dtv. Just like the cinema version.
Oh and VR tech is here. Have you tried google cardboard. Cheap but impressive. Next year Big vr headsets like occulus will be commercialized. So 3d is coming back with VR. And there is no way for VR to work without a headset. Lets see if its a hit!!!
A glasses-free TV produces a series of alternating hot-spots and anti-hot-spots (with left and right reversed), and between those spots are nulls. In order to get past this, you have to radically increase the number of stripes in your lenticular pattern. 4 stripes can produce 3x as many hot spots as anti-spots.
But right now, with essentially square pixels (glasses-free TVs use ordinary LCDs with lenticular screens in front of the LCD) even 2:1 is annoying because of the imbalance it created between horizontal and vertical resolution. You can't get to higher lenticular ratios unless you build LCDs specifically for 3D TV, with much higher horizontal resolution than vertical.
Existing offerings are also distance dependent. View it at half the ideal distance, and you get all nulls, alternating regions where both eyes get the left eye image, or both eyes get the right eye image. View it too far back and you get crosstalk.
Not really. Just a cheapened version of the Hasbro My3D, which crashed and burnt 4 years ago. The Google name gets a lot of attention, but I haven't seen anything really compelling come of cardbloard, yet.

The human eye isn't color corrected. There's a 1.5-2 diopter shift from red to blue. With complete spectral information to each eye (no color filters) this causes highlights to have a blurred color "glow". We're not usually aware of this, because our built-in "software" compensates for most of the chromatic aberration in a scene and removes the glow. But when we put on magenta filters, the discontinuity in the spectrum makes us painfully aware of the chromatic aberration. Everything bright with a reasonably high white content acquires a well-defined blue halo that we are not programmed to ignore.
The first two actually minimize visible halos because they restrict each eye to at most 2/3 of the visible spectrum. There is a diopter shift between the eyes, but we compensate for that well, and really nice 3D glasses can also be compensated for it.
AMBER/BLUE (or yellow/blue, patented as Colorcode 3d): They tried a lot to promote this format as the new anaglyph standard during a superbowl game (in 2009 I think) with an episode of chuck and a couple of movie trailer. The company claims that left amber filter allows almost all color information to be viewed. People say that its a lot darker because of the dark blue right filter.
The dubois view is actually the most comfortable and I have found that the colours you see on screen without glasses are almost exacly the colours you see with the glasses on. If thats the case then with the Amber/Yellow format seen with dubois the image is almost similar to the original.
Ultimately, each of the 3 color combinations has advantages and disadvantages. My personal belief is that the red/cyan is most compatible with human visual pigment electrochemistry, so in side-by-side testing, it ultimately wins out by being the most "balanced" approach.
