Anaglyph 3D Glasses For the Internet - It's a whole new dimension when you add virtual reality to your web site. These glasses are an affordable visual enhancement to the cyber world. Surf the net...develop your own 3-D images...explore new depth defying worlds.    Anaglyph images have seen a recent resurgence due to the presentation of images on the internet. Where traditionally, this has been a largely black & white format, recent digital camera and processing advances have brought very acceptable color images to the internet and DVD field. With the online availabilty of low cost paper glasses with improved red-cyan filters, and even better plastic framed glasses, the field is growing fast. Scientific images, where depth perception is useful, include the presentation of complex multi-dimensional data sets and stereographic images from (for example) the surface of Mars, but due to recent release of 3D DVDs, they are increasingly used for entertainment. Anaglyph images are much easier to view than either parallel sighting or crossed eye stereograms, although the later types offer bright and accurate color rendering, which is not quite obtainable with even good color anaglyphs.

The effect is named after Carl Pulfrich who observed that if a pendulum is swung across the visual field (i.e., perpendicular to the line of sight) and one eye is viewing through a light-reducing filter, that the pendulum will be perceived to be swinging in an elliptical orbit, rather than the linear arc in which it actually swings. Objects in constant motion may appear nearer or further from the observer than they really are, and if moving past the observer obliquely, they may appear to veer towards or away from the observer.

The effect often occurs spontaneously in several eye diseases such as cataract, or optic neuritis in multiple sclerosis. In such cases, symptoms such as difficulties judging the paths of oncoming cars have been reported.

The Pulfrich effect has been utilized to enable a type of stereoscopy, or 3-D visual effect, in visual media. As in other kinds of stereoscopy, glasses are used to create the illusion of a three-dimensional image. By placing a neutral (transparent gray) filter over one eye, a moving image perceived by that eye will lag behind the image perceived by the unimpeded eye. This lag will induce a difference in the images perceived by each eye, inducing a binocular vision illusion of depth.

Because the Pulfrich effect depends on motion in a particular direction to instigate the illusion of depth, it is not useful as a general stereoscopic technique; for example it cannot be used to show a stationary object apparently extending into or out of the screen. However, it can be effective as a novelty effect in contrived visual scenarios. One advantage of material produced to take advantage of the Pulfrich effect is that it is fully compatible with "regular" viewing without glasses.

This effect was exploited in a "3D" motion television commercial in the 1990s, where objects moving in one direction appeared to be nearer to the viewer (actually in front of the television screen) due to the binocular vision of the user. To allow viewers to see the effect, the advertiser provided a large number of viewers with a pair of filters in a paper frame. One eye's filter was a rather dark neutral gray while the other was transparent. The commercial was in this case restricted to objects (such as refrigerators and skateboarders) moving down a steep hill from left to right across the screen, a directional dependency determined by which eye was covered by the darker filter. The effect was used in the 1993 Doctor Who charity special Dimensions in Time and a 1997 special TV episode of 3rd Rock from the Sun. In many countries in Europe, a series of short 3D films, produced in the Netherlands, were shown on television. Glasses were sold at a chain of gas stations. These short films were mainly travelogues of Dutch localities. A Power Rangers episode[1] sold through McDonalds used "Circlescan 4D" technology which is based on the Pulfrich effect.
