Stereograms? (3D without glasses)

[Satchel]

Anyone know how to make a Stereogram (http://www.well.com/user/jimg/stereo/stereo_list.html) or (Stereo Image) in flash?

They say that you can do it, but a google search hasn't really helped... I have found how to make the ones you need the glasses for and a program or two (for windows) that makes the kind I'm looking for, but I want to learn how to do them on my own.

It looks like two pictures skewed and/or just a little off from each other and faded quickly between the two, but I tried it and it ended up just looking like it was skipping around, not the actual "3D" look. This is sort of just a side project, no real rush but I thought if someone already put in the research they could help... if not I'm sure I'll figure it out sooner or later.
Thanks,
Satchel

Link isn't that SFW

Some stuff wiggles more then others depending on where the center of wigglyness is.

[Broacher]

Looks just like a little wiggle loop between, what, 3 or 4 frames from slightly different positions? (But then, why aren't those buns wiggling?)

[Satchel]

Yeah it seems like the whole picture has to be sliced up... I think it looks pretty cool, but potentially a lot of work...

Had to go there didn't you Broach. I don't blame ya'. In fact, I'm upset at myself for not saying something first. :P

I think the way they are doing it is similar to camera mapping in 3-D movie making. I am not that versed on this, but I have lately been hanging out at matte painting sites and alot of the pros in the business are called on to make a 2-D matte painting into a moving 3-D shot that the camera moves through and around, check out this thread for a good example of this:

http://www.mattepainting.org//forum/viewtopic.php?t=980&highlight=camera+mapping

Once you have read through that thread check out the finished version of the 2-D photo as a 3-D element:

And you might wanna check this out too to get the skinny on one way to do this:

No, really, it's not that hard. You set up maybe 3 or 5, or whatever number of cameras and tripods all focused on the same thing, but offset each by maybe a 5-10 degrees of the arc of the center camera. Synchronized shoot. Then you make a Flash sequence that goes from center, left 1, left 2, left 1, centre, right 1, right 2, right 1-- and then loop that. Result? Wiggling backgrounds that wiggle in relation to their distance away from the center soure. Result? 'Animated' 3D illusion. If you don't synchronize the shot, like the one where the fabric is blowing in the wind, you can make the wiggling seem more like it's part of the action. But this isn't rocket science. 'Now hand me that scalpel!'

[Satchel]

Damn, you cant do it from an existing photo... that's too bad, but it makes sense. Seems a lot easier when you put it like that, then trying to figure out how to take an existing picture and make it "wiggle" Thanks everyone.
S,

Yeah what broacher said is WAY easier than what I had found. After I initially posted I found a photography site that outlined it (in a more watered down way) what broacher said. Doing it broachers way is easier and make it cooler, I would imagine, than the examples linked to by Satchel.

it is a pretty cool efect but it might bug the visitor of your site have one of those jiggleing around in the corner.

[kerrysmagicshirt]

i had a brows round the origional site and ended up here

guess that kinda explains it - sort of

if you were setting up syncranized camras you may as well go the whole hog and get some full 360 images - create a circle of cameras around a centeral subject - it's been done for a while - like the suspended animation 360 effects in the matrix - the cameras visible from the other side of the circle are simply brushed out afterwards.

[Broacher]

If it's a stationary object, or scene-- you can of course do it with just one camera. Heck, I bet with a reasonable amount of steadiness and a little Photoshopping alignment, you could even do pull this off handheld, sans tripod. But I agree about the annoyance factor-- you'd really have to justify including this stuff anywhere with something that would override the gimmickry or it's just that.

actually my sister has been asking me to do something with a picture of her daughter that is "cool" and "different" and I thought this may peek her interest... I would never do this for anything commercially.

Sorry that I didn't see this until WAY late. But, this is a topic that intriques me.

As someone has already pointed out the baseline that you need for creating a Crossed-Eye 3D image (Stereo without glasses) are two slightly different images created specifically with 3D in mind.

If the originals are photographs, then the camera is moved slightly to one side. before the second image is taken. One of the masters of this technigue goes by the name of LordV on the major digital photography forums. His work is amazing.

The other way to create a 3D image is to use a 3D Modeling Program, like Mudbox 3D, and capture two 2D images, one slightly rotated. But, you don't need the power of Mudbox to have fun at this genre.

If anyone would like to experiment with 3D modeling in general and Crossed-Eye 3D in particular, I've run across a family of excellent, low-cost programs to try. But, first...Because my suggestion is going to be so glowing and I'm new around here, I'd better make it clear that I do NOT work for the software company that made this product. I've simply had a lot of fun with them. :)

The first is a child's program, by SolidWorks, called CosmicBlobs (Many years ago, I was a game developer for major publishers and this is THE most fun activity I've ever seen!) You can download a free trial at www.cosmicblobs.com (http://www.cosmicblobs.com). ($39 to buy) The second is now in beta and available as a free download as long as the beta is in development... which will be for a while. It's the 'Pro' version of CosmicBlobs and can be downloaded at www.cbmodelpro.com (http://www.cbmodelpro.com). While it's still in it's infancy, it's should be an important new 3D product when it's finally released.

Here's a sample Crossed-Eye 3D Stereogram images I put together using CB Model Pro's base blob primitives:) . I've purposesly used very simple images to show the concept.

And here's one built using CosmicBlobs

In both cases it took just minutes to complete.
