[edit] Disambig

Disambig for Steriogram (and vice versa on the other page?) I don't know how to do this, but still --90.208.173.167 (talk) 12:34, 4 May 2008 (UTC)

Possible contradiction on linked page Stereoscapy: "was first invented by Sir Charles Wheatstone in 1838. Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms." If this is true, how were stereograms (described as photographic) invented in 1932? Or were they invented in non-photographic form in 1932, then made photographic later?

[edit] Policy discussion

Editors of this article may have interest and expertise that would be helpful in developing policy relating to use of 3D images here at Wikipedia. Please see Wikipedia:3D Illustrations and the talk page to participate. Thanks! ++Lar: t/c 02:47, 30 January 2006 (UTC)

[edit] Seeing it reversed

Whoa... I think I see the sample image reversed -- the peaks look like lowest points, and the lake is on the top. What am I doing wrong? vmaasalo

You are diverging your eyes, i.e. focussing on a point further away than the image. It's intended to be viewed by crossing your eyes, i.e. focussing on a point between your eyes and the image. I see it backwards also, since I can't view cross-eyed stereograms, only divergent ones. I've put some stuff in the article on this. 128.232.250.254 12:30, 20 May 2006 (UTC)

xD Pictures just need to switch their places. Try it in MS paint. For some reason they are put wrongly.

[edit] Stereograms for 3d imaging of molecules

Anyone here know anything about the use of stereograms for imaging molecules? Several molecule modeling programs (such as RasMOL) have the ability to generate a 'stereo pair' of renderings, meant for easy stereoscopic viewing (crossed eye type, typically). This use of stereograms as a tool, rather than just a curiosity, is facinating. I'm going to do some research and try to add some of this to the article as I get time, but I wanted to invite anyone else to join me if they would like. Phidauex 15:36, 29 June 2006 (UTC)

That would be great! But I don't have experience with these programs. I look forward to seeing your additions. Fred Hsu 00:36, 30 June 2006 (UTC)

I've added a bit on space exploration... Its still stubby, but it's something. Next up, chemical modeling. Phidauex 16:49, 30 June 2006 (UTC)

[edit] Wiggle-gram

I added this as a type of stereogram. This is not commonly considered as a stereogram type but I think it is a very useful and interesting technique. The name is according to User:Tablizer in Image:Home_plate_anim.gif I encountered an instance for the first time in a file named 3dgoddessrp4.gif in a myspace profile which i don't remember the name. But here I upload it: Image:3dgoddessrp4.gif. Not sure about the copyright. --Sohale 18:41, 17 March 2007 (UTC)

In that case, a cross-eye stereogram is in theory just a filmstrip of a wigglegram. --Damian Yerrick (talk | stalk) 03:11, 3 December 2007 (UTC)

[edit] Stereograms being harmful

I heard from a optometrist (or some other eye expert I cant remember) that crossing your eyes too look at stereograms is bad for your eyes. Can anyone back this up for me? 58.175.80.19 (talk) 02:25, 17 February 2008 (UTC)
