This is made from the FLV that is on howcast.com so the quality is lower than I’d like but I can always redo it if someone wants to provide a better source.
You will need Red Blue Anaglyph Glasses.
The Amount of 3d you get is inversely proportional to the amount of color retained by the image, so this doesn’t pop as much as it would if I was willing to present in Monochrome shades of Black to Magenta.
And Because RED/Blue doesn’t 100% filter what is being presented you will see some halo-ing or shadowing around very bright objects like some of the text. This Is just a limitation of the technology… (which was debuted in the 1920’s).
Did you know: The First 3d Feature Film was Power of Love which debuted in 1922?
Did you know: 3d works best with Red Green glasses, but because of the large number of people with this specific color blindness it could not be mass deployed.
About the Technology:
The process used to convert this video is a combination of Geometrically Coherent Image Interpretation, and Motion Vector Parallax Detection. These two methods have their own strengths and weaknesses so the depth data calculated from the two methods is averaged to create the depth map which the image is then warped against. Neither eye sees the original frame in this method which makes this technique suboptimal for the encoding of videos for Mass market because you can’t actually turn the 3d effect “off” by simply presenting the left or the right eye. “Good” 3d Video is shot on 3 camera’s at the same time one for the monoscopic, one for the left eye and one for the right eye. Mediocre 3d is shot on two off centered cameras.
Bad 3d “aka Alice in wonderland” is shot in 2d and the 3d effects that are added to the movie as special effects are renedered in 3d for each eyes, leaving the original 2d film to be “upconverted” when the effects are added.
This results in the ‘pop-up’ book effect where objects are 2 dimensional but presented in a 3d plane.
The Technique used for this video obviously was shot on one camera and then math is applied to simulate the 3d effect. The downside to this technique is that occasionally ojects which don’t intersect the line of site may have the wrong depth, if they then cross the line of site a few seconds later they can “pop” in to the fore ground or back ground, or even ocassionall appea to exist with in the object they are passing in front of. This is rare, but when it happens it can be quite disconcerting.
