This cart allows you to create simple "Magic Eye"-style stereograms: 3D images hidden inside a field of seemingly random dots.

Create stereograms by drawing a depth map. This is a picture where different colours signify different distances from the object to the camera. When you're finished, select "make stereogram" to turn your depth map into a stereogram.

These stereograms are designed for parallel viewing. Relax your eyes and allow them to diverge, as if looking through the screen at something much farther away. The two black dots at the bottom of the picture should become three dots, with the middle one in focus. Then the hidden 3d image will emerge. If you're having trouble seeing the pictures, you can search online for "how to view stereograms" for lots of detailed explanations.

The algorithm for creating the stereograms comes from Inglis, S., Thimbleby, H., Witten, I.H. (1994) Displaying 3D Images: Algorithms for Single-Image Random-Dot Stereograms, IEEE Computer, 27(10), pp.38-48.

This is excellent stuff! :D

I've always loved RDS images - ever since FINALLY "seeing" a Statue of Liberty one in Athena, back in the 90's.

Love that you managed to translate this to Pico-8 (considering the limited depth/colour option) - even BETTER that you allow us to create our own ones too!

Nice one! :D

Really awesome, I like Stereogram-Images. Never thought I would see an Implementation done in Pico-8 :D

Totally like it^^.

really cool, I've always wondered if it was possible to make animation with stereograms? that would be fun to have a game with these graphics :D

Woah this is really dang cool!
Stereograms are fascinating and being able to just readily make your own is awesome

okay, this is really cool! I always liked them

This is awesome, I didn't even know there were algorithms to generate those!

Thanks for this sweet cart and for linking the paper <3
