My time has come!
The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)
This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.
Here are some other stereopairs published by JPL:
Wheeler Ridge, California
Mount Saint Helens
Salt Lake Valley, Utah
Wellington, New Zealand
If you want wall-eyed viewing, you can just download the image and
mirror flipswap it in an image editor. I also personally prefer wall-eyed viewing.This is exactly how JPL posted them, and they did cross-eyed viewing because the image jumps out of the page, rather than in (I presume).
Incorrect. You don’t mirror flip it, you swap the images to convert between cross/parallel view.
Source: I wrote my own stereogram software, I know the difference.
Is that available somewhere?
Ah yes! Sorry, the stupid thing is, I knew that and said that to someone else last night! Thank you stranger!
