Was wondering if anybody can see the hidden 3D image in here:

Also I was wondering if anybody has ever tried making a stereographic image? Might be a fun project to try one day.

So far I can see the hidden images in all of these easy. There are some hard ones though, but these 3 are pretty easy to see.

funny you mentioned that, i actually made on one time... here check it out... it is a picture of me from two different angles spaces apart about the same width as two eyes (a little wider for a more vivid 3d effect). so view it the same way you would view the above 3d images.. just let your eyes cross... it DOES work and its pretty damn cool. tp bring it into focus, get about 1 - 2 feet away from the screen and male your eyes focus the two images together into one... you will be focusing on the middle image when your done..

Yes its a helicopter :)

Pretty cool thing you did with your face there. Was it very hard to make yourself 3D ?

i can't get it to work for me. I've done them before, but i can't get these.
I've tried a few times each and never gotten one yet. :roll:

i'll keep trying I guess...

no, basically took a couple tries but i was holding the camera and i snapped shot one then .. moved it over about 4 inches and snapped image two... then merged them together to make a 3d effect

You forgot to explain that we would require glasses after staring
at pictures of your face ...

but yeah, I seen the effect ... looks kewl !

two then there's three.

You know what would be interesting to see is an entire web site made in stereographic images!!! complete with all the links and text and stuff :)

Something for you graphics savvy people to think about :)

ok - so after about an hour, i finally got 1!! the 3-rings one was the first
one I could finally get.

Then I got the helicopter pretty easy.

then I spent another hour (i swear) trying the last one. finally got it...very cool face-thing.

I can't get the one with gadget yet tho.

There is software Stereogram Explorer, but some problems with loading 3DS models on newer graphics cards. Stereograms gallery
http://www.aolej.com/stereo

there free is stereogram creator too (http://www.aolej.com)
and stereogram screensaver with hundreds pics

This is good training picture (created with Stereogram Explorer)
If you don't see string, you never see stereograms :(

This is totaly sharp stereogram picture :roll:

Image

and when you trained see complex 3D model

Hehe, they can take a little getting used to...

Basically, you need to FOCUS your eyes on the screen, but you need to AIM your eyes as though you're nearer than you actually are... It's tough, but usually once you can see one, the rest are real easy...

But, some people can see them, some people can't. :)

Yeah.. Have you seen the stereo photos too? Similar theory, but you don't have to have a greyscale gradient as a heighfield...

Basically 2 photos, you focus your eyes on them for distance, but you aim your eyes nearer than the subject so that the pictures line up on top of each other...

I'm thinking of buying a second D100 (heh) and a Sync cord to make them both fire at the same time, so that I can do stereo photography.

To not muddy this SIRDS thread with 3D Photos, I made a new thread..

It isn't that I don't know the theory on how to make the hidden pictures appear, I am physically unable to do it...

I'll give you an example of what I mean.

As an electronics tech for the first ten years of my working career, I have done a lot of soldering..!!! I am unable to solder efficiently at small scales, because I have no perception of depth, due to my brain using only the information from one eye, not both. :(

Apparantly, people with perfect vision only ever use binocular/stereo vision to a distance of 4m, everything after that is monocular anyway...
so it is only a disadvantage for close in work.

think of firing a rifle... you close one eye, right?? your brain only uses/needs the information of 1 over long distances.

And since I have been this way forever, I have just learnt to adapt and really don't know any better...

Except for those 3d/stereo images :( Some times... like now in this thread... I really do notice the disadvantage!!... it would be really good to "get" them!!!

Nope, it's a coupla hundred foot or so from what I read... Otherwise, people wouldn't know whether that car in front of them sharply applying the brakes was 20ft ahead or 50ft ahead :D

Just so you know,

streoscopic vision relates to the rror that exists metween viewing one object from two different sources.
Ie. two different eyes, in different positions in your head.

as the object gets furthwer waway from you, the Paraallax error if you like, is insignificant after 6m of distance (I thoght it was four - just got told by an optomotrist it is about 6).

So your brain still uses two eyes over long distances, but you are actually not seeing difference any longer, after that object is more than 6m away from you.

ONE OF THE MOST fascinating aspects of our vision is that we can see in three dimensions, which permits us to judge distances of objects from us and from one another. This ability is known as stereopsis, and although there are a number of factors that contribute to it, the most important - at least for distances up to about 200 feet (60 m) - is binocular vision ("two-eyed seeing"). Our eyes are separated by an average of 2.5 inches (64 mm) and each one sees a slightly different view than the other.


I'll admit that it is much easier to judge the longer distances by having a frame of reference within that first 20ft you mention, but there are noticable differences at further distances.

I guess it depends on how good your eyes are. On a 14" monitor, I run in 1024x768, on a 15" I'm in 1280x1024, on a 17" or 19" I'm in 1600x1200 if the monitor can handle it, that's way too small for most people sat only 12" from the monitor, but I can read Verdana size 8 on a 19" 1600x1200 CRT from a distance of 4-6ft away from the front of the glass. So, I'm probably better at picking out the details on longer distances so the difference is more noticable.

As I said, over 20ft, the differences between each eye are extremely slight, but they are there.
