How To See In 3D On Your iPhone

waderoush writes "Some of the coolest media technologies predate the Web and the PC — in fact, they predate the 20th century. My column in Xconomy explores the world of 19th-century stereoscopes and stereo views, which are the all-but-forgotten forerunners to anaglyphic 3D, VR goggles, and other modern stereo vision systems. As it turns out, it's pretty easy to 'free-view' vintage stereo images on an iPhone or other small screen, getting the full 3-D effect without any other viewing aids. The article has instructions for accessing a collection of old stereo images using the new Seadragon Mobile iPhone app from Microsoft Live Labs." The stereoscope, that killer technology of the last century but one, was invented in 1859 by Oliver Wendell Holmes Sr., who gave it away and never made a dime off it. If you don't have an iPhone and want to get the feel of free viewing on a computer monitor, start here at Roush's Flickr photostream.

But in an online forum of strangers? It's a lot easier to misjudge tone and intention, and to be on the lookout for trolls. When most of the time it's guys purposefully being rude and disrespectful, it's very easy to see it where it isn't happening. It's a personal, emotional kind of attack, and it's only natural that women get a bit defensive about it when they're outnumbered.

    1. Re:Note on the invention of stereoscopy... by Anonymous Coward · · Score: 0

      Or, if you like, another stereoscope 'inventor' is Sir Charles Wheatstone: Brittanica says it was "First described in 1832 by English physicist Sir Charles Wheatstone". The 'Viewmaster'-type stereoscope was created by Sir David Brewster, an improvement on Wheatstone's design.

      Wheatstone didn't invent the Wheatstone Bridge ... he 'popularized' it (and got his name on it); British mathematician Samuel Christie invented it. He did invent the Playfair Cipher.

      http://www.britannica.com/EBchecked/topic/565655/stereoscope

      There's not much certainty in those old attributions; Brittanica doesn't always agree with itself. Possibly it was an old gizmo (say, from the 1600s) that, later, clever men seeking fame 'invented' anew. In those times, people didn't seize on such stuff: Brewster had to go to France to find a manufacturer.

      "Binocular drawings were made by Giovanni Battista della Porta (1538-1615), whilst about the same period Jacopo Chimenti da Empoli (1554-1640) produced drawings side by side which clearly indicated his understanding of binocular vision. In 1613 the Jesuit Francois d'Aguillion (1567-1617), in his treatise, coined the word "stéréoscopique""

    Yup. In 1934, Wheatstone demonstrated stereo using hand drawn figures. He then got onto his friend Fox Talbot, and they made stereo pictures. Perhaps there was only six months between the arrival of practical photography in Britain and experiments with 3D. It was sxhibited in 1838,

    In Europe, Duboscq developed viewers that showed transparency stereo pairs. These became popular ince Queen Victoria had been presented with a model at the Crystal Palace exhibition.

    The Holmes stereoscope was a simpler instrument without optics, and it used reflection images. These gave less intense images, but the stereoscopes and the images could be mass produced. You still find them in US junk shops. Holmes didn't invent stereography any more than Eastman invented photography or Ford invented the car. But he did make them popular in the US.

That's absolutely correct -- my mistake. I've revised the article to link to a different tutorial, on parallel free-viewing. I've never actually tried cross-eye viewing, which sounds a lot harder. If you try to cross-eye free-view these images, they will indeed look inverted or flat. But once you get the trick of parallel free-viewing, the images should pop out at you, especially the best ones like the Brooklyn Bridge pictures at the beginning of the photoset.

    Many of these images were taken with excessive spacing between the views, which makes things "pop-up" unnaturally.

    I used to do this for a living several careers ago, doing 1500x photomicrography pairs at a research lab. I have no trouble viewing, but some are not lifelike, at least defined as "as the eye would see it." An interesting collection for all of that.

    When using a telephoto lens, the distance between views should be the interpupilary distance times the zoom, or 195mm for 3x zoom, as an example. Trying to show the contour of a mountain miles away, I did once use a separation of about 10m, but that was to compensate for the zoom and exaggerate the depth to locate features, and was not intended to be lifelike.
