3d cross eyed images

Post your own tutorials, guides and demos.

Its a weird optical illusion thing where if you have two images and you cross your eyes you can see a third image in the middle. However, your left eye sees the left image, and your right eye sees the right image, and thus by providing two separate images from the left and right eye, your brain can see depth (depending on how the images are drawn).

Photos are taken by positioning the camera in the two 'eye socket' location...but really you can cheat and just horizontally move the camera.

I made a simple cap explaining how to see these images, I think I might make another cap that uses 2 canvas's and construct parrallaxing...

It's a neat effect but I can't see playing a game like that. Ouch.

I have some 3D glasses lying around here, maybe I'll tinker around with that and see if I can't get some 3D effect working.

Cool theory but yeah, I agree with deadeye... on a rather cheap, low res (by today's standards) CRT monitor, and while the effect can be seen, it's all a bit blurry and things are very far apart making it hard work to cross your eyes that much. I guess it doesn't take in to account the physical size of the user's display.

haha I've reached the point where I can see the image in the middle as clearly as the image of the left or right.

However, I had a 3d picture of a hot female model in front of me...so like...yeah...its a lot easier to focus on a hot model than a construct logo ;P

But yeah your eyes dont like being crossed...if the image on the screen is small then its not as painful on your eyes (my screen is 1680x1050) not sure how large my screen is...so yeah standing back from the picture helps a lot but then its harder to see whats going on.

I've seen flicker glasses that come with graphics cards and stuff, the idea being that it blanks out the left eye, and then the right eye, in sync with the graphics card, which renders slightly to the left and then slightly to the right so you get the flickering like in my first layout.

Then theres the blue and red effect, where the left eye can only see one colour, and the right eye can only see the other, but it kinda prevents you seeing colour....also it requires people to be wearing red/blue glasses.

The cross eyed effect is the only one that you can do without the assistance of glasses or a 3d lcd screen..but it hurts your eyes :(

For some reason I have two pairs of Shark Boy and Lava Girl 3D glasses, but I've never seen that movie! I swear it.

I kind of like the red, blue glasses, very retro, and would rather give up full color for that. I would expect you could make up some amazing stuff with the new z depth function.
Matter of fact you would think a game that needed the glasses would probably wind up being pirated a lot less.

I saw an animation of a swimming shark using that technique once.

Seeing it in motion is actually just as easy and tiresome as seeing a still.
It even might be easier to see because of the way our brains process images.

However, doing that for more than a few seconds would give you horrible headaches.
The future in 3D seems to be special multi-angle displays for home and polarized displays with glasses for theaters.
