3D Origami Photos

I came upon an idea that it would be interesting to post some 3D or stereophotos of our foldings. They have to be looked at with the so-called "stereo glasses" (one red and one cyan glass). Well we trade the colours for the view here but still it is nice.

Here is an article about how to make such photos:

And here is a simple free program for it:

Here is an example of Satoshi Kamiya's Mammoth:

Hey, that's pretty cool. My old biology professor was into this kind of thing but I didn't think about applying to our origami photos. I wish I had some stereo glasses handy, hah.

Just too bad I lost my 3-D Glasses! :wink:

A quick test...

How should it works?
Is it an "animated" gif?
I tried to download the original picture from Flickr, but I don't see any 3D...

The image above should be animated already (and it is on my computer).

But yes, it's an animated GIF. Some image viewers don't show them as animated, though.
If you can't see the animation, I'm not sure what the problem is.

If you can see the animation, but can't see the 3D effect, that's a different problem entirely.

Here's a quick red-cyan version, which works well if you have the glasses:

I must check why my computer hates animated gif!

What kind of camera did you use? and the software?

All my cameras (old film cameras...) have only two lenses, I made some experiments taking different pictures with an electronic camera on a bar-slide and even free hand, almost successful

You can right-click the image and choose "View picture" or "View Image", then give it a chance to load fully.
If it still doesn't work, I'm not sure what the problem might be.

A Nikon D40, which is a basic digital SLR.

I took one photo from the center, then moved the camera to the left a little (keeping the lens pointed straight forward) took another shot, then did the same to the right.
Then I layered them in Photoshop, aligned them and created the animation.
I'm sure you can do the same thing in GIMP (which is free).

Mine were done freehand, too, but a bar slider would be preferable.
Experiment with distance, too. Too far either way can ruin the effect, but it needs to be far enough to produce a decent 3D effect.

Make sure the subject is a good candidate for 3D, too.

Also, pay attention to where the images match when you overlap the images.

Image

The image on the left has the front of the box aligned, the middle image has the body aligned and the image on the right has the lid aligned.
The blue line shows where the plane of the screen is.
In the left image, the front of the box will appear at the same level as the screen, with everything else behind it.
The right image has the lid at the screen level, with everything else appearing to come out of the screen.
The center image has the center of the model at screen level, with the lid (and back of the box) going into the screen and the front of the box (and model) coming out.

So, try to make sure that the 3D effect works the right way for the model you're using.
For example, having a unicorn's head and horn coming out of the screen would be more effective than having the entire thing going into, or coming out of, the screen.

To "turn-on" the Gif Animation, try looking at the picture in a browser. It's a 10 year old technology, pre-PNG, and before JPG were cheap to create. I think that most email programs don't show the animation as well as browsers.

However, some picture edit programs will let you edit/modify the "layers."
(Not true layers like in Photoshop.)

BTW, it is possible to GIF Animate the Red/Blue to see what happens ?

(For those who understand the math, what I really want is a virtual image of the virtual image :-)

"Frames", then, rather than "layers"?

I'm not sure I understand exactly what you're asking, but you could make an animated GIF using the red/cyan anaglyph images, basically making a 3D movie.
But there's not much to do with an origami model, except maybe rotate it. Unless it's an action model...

I would love to make a 3D movie of the Jack popping out of the box, but I don't have a 3D camera, and getting the Jack to move in exactly the same way twice would be unlikely, so it's not feasible.
Also, not having a bar slider, it would be difficult to get the images separated by the same distance each time.

A little low tech Hack in the Box :-)

Code is very easy to modify with other Stop Action pictures....

Probably using Linux and Opera doesn't help...
I always had problems with the animated gif

I made some shots this way (without the central picture) in the past

sure, the "window composition" of the old-school..

Nice effort, but unfortunately all the other frames seem to have lost their 3D effect. The colours are slightly different, so there's a faint "ghost" of both images in each frame (except the unedited one).

I could fold it from some tissue-foil, which would probably allow me to put the Jack in different positions without it springing back...
