stereograms

For a VR project I’ve been working, I decided to make some crosseye stereograms. You don’t need funny glasses, you just need to be able to cross your eyes for a few seconds at a time.

To see in stereo, cross your eyes until the left image and the right image overlap completely in the middle. Relax as you look around the scene. Stop crossing your eyes if you feel any discomfort, but practice builds up your eye muscle strength. No, you won’t damage your eyes doing this! It’s fun.

And a couple others on other subject matter. The first one is good for crosseye beginners. The third one is a bit more advanced.

aargh, i cant do it><

Funnily enough, I created a stereoscopic image a while ago:

KEWL!!
this adds a whole new level to the 3D in blender (for me)

so you did this just by copying the image and placing it right beside the original?

what a great idea!
I love it!!

thanks for shareing!

btw I really like the picture inside the house. that was the coolest one :smiley:

Just render one image, save it as yourimagename_l, then move the camera left one unit along it’s local X axis, re-render and save it as yourimagename_r. You can then put the pictures together in your favourite image editor.

anyone got tips on how to look cross-eyed? :expressionless:

bad news
some people cant look crosseyed
it’s a gene thing

…I think

Sometimes it helps to hold a stiff white card (~15 cm long) vertically between the dividing line and the tip of your nose. Play around with the distance between your nose and the monitor. You still need to relax as if you’re looking into the distance.

EDIT: I stand corrected, divergence/white card definitely will not work here (see downthread). Follow Halley’s cross-eye directions to view these amazing images.

Lucky for me, I’ve been playing with my eyes since I was a little kid, so this was fun for me. (not everyone has a complaint!) :smiley:

The last one actually was hard to look at. If you made one of the pyramids red or something to help my brain establish a real difference between the two images, it would be much better. The floor pattern was also kind of distracting.

I really really like the japanese room. Perfecto

Very nicely done!

Tips for going cross eyed - hold a finger about a foot away from your face, focus on it and then bring your finger to your nose, then try to keep your eyes in that position whilst removing the finger :slight_smile:

The lastimage isn’t actually a ‘true’ stereoscopic image. the images are the wrong way round.

EDIT: Rotating your head slightly works. Maybe the camera wasn’t moved along it’s local X axis.

The second-to-last one is amazing.

haha thats pretty cool good job

heh… all you have to do is get one that you can easily focus on then scroll up and down instead of focusing on them all individually.

It’s not going crosseyed, it’s more like going cockeyed. Your eyes go outward rather than inward. If you cross your eyes the images spread apart rather than come together. I did a project on this in like the 7th grade. I took two pictures with my digital camera(the second moved to the right and focused on the same object) and made them small, cut them out, and pasted them side by side on a piece of cardboard. I made a cardboard box, cut two holes to look through, cut slits to slide the cardboard slide through, and put a divider down the middle so that one eye could only see the image on it’s own side. It was sweet.

By the way these are very nice.

HAHA i did it!

cool. I actually liked the last one the best. although it was hard to focus on it, it was the most 3D looking when i finally got it.

i can’t do these either. but i can do those “magic eye” streograms almost instantly. anyways, good stuff!

No, these are definitely cross-eye stereograms. The right camera’s image was placed on the LEFT for each pair (including the magtoy one). If I had put left camera images on the left, then yes, they’d be traditional walleye stereograms like the Victorians liked to produce, and like the old “Viewmaster” toys would use. In those, the white card tricks work better.

One reason the magtoy image is so challenging is because the parts are all very similar so it’s hard to knit. The other reason the magtoy image is challenging is because the ipd (inter-pupillary distance) is pretty extreme for this close-range subject, so the far pieces don’t knit as well as the front pieces. I will be redoing it with some tweaks, and it should be a lot easier for newcomers to use.

fine, i can get hem right but I JUST CAN’T GET THE VIEW SHARP! :stuck_out_tongue:
