After having read about the Nintendo 3DS all day, I've been dying to see this 3D effect in action. This is really awesome.

Now the question is, is there an easy way to do this with our own content? I would love to mess around with this technology.

EDIT: These images came from here: http://abduzeedo.com/stereoscopic-images-inspiration

I now know that these are stereoscopic image examples. My question still stands though, what would be the easiest way to go about reproducing this effect? It seems like mounting two flip minos could be really cool if this would work.

Anyone know of any really smooth examples of this technology?

I imagine the 3DS effect will look very similar to these: http://digital-photography-school.com/9-crazy-cross-eye-3d-p... , since each eye is receiving different images. Except with the 3DS you won't have to cross your eyes.

I work as a software developer for a company that develops autostereoscopic displays (For seeing 3D without glasses - like the Nintendo 3DS will do) and stereoscopic software. We are currently developing a line of products for iOS devices to watch videos in 3D and see images and read comics (eventually) in 3D. So at some point this year when it all gets launched hopefully you can pick one up for like $15 for your iPod/iPhone/even iPad (although I don't know that the iPad version will end up being $15).

Edit: I should add that it appears the Nintendo 3DS is using a parallax barrier (but I don't know how true that is - I've heard it could be using a different system too, haven't seen one though). Our technology is using lenticular mainly, so the images will be quite different from both. Lenticular, for example, preserves the brightness of the image much better than parallax barrier.

Using wiggle stereoscopy?

Nobody uses wiggle "stereoscopy" for anything but novelty pictures. It's just not a practical technique.

"see images and read comics (eventually) in 3D"

Sounds like it could be called a "novelty" app to me, and one I'd really like to see happen. Regardless, what other methods are available for getting "3D" out of iOS devices? "Cross-eyed" 3D seems even more of a "novelty" to me.

EDIT: Perhaps "a line of products" means hardware in addition to software. I read it initially as meaning a line of apps.

No, lenticular stereoscopy.

You print vertical black lines on a transparent sheet of plastic, and attach it to a 10mm thick piece of transparent plastic, and attach all that to your monitor for a cheap and easy DIY parallax barrier. From the proper distance, your left eye sees a different set of pixels than your right eye. Add photoshop, and voila, 3D.

(random example: http://www.youtube.com/watch?v=yu92wwR1b1g )

Imagine if you had a TV alternating the images at 60Hz, and a pair of glasses which flickered each side opaque/transparent at 30Hz...

I believe that's how the SegaScope 3D glasses worked, back in the mid-'80s: http://en.wikipedia.org/wiki/Sega_Master_System#SegaScope_3-...

It's also how the current nVidia implementation works: http://www.nvidia.com/object/3d-vision-about.html
