I started programming this one way back in 2022!
You actually need a real rocket here, best is an emulator or a Vampire accelerator.
It can take a while to process the image and make a stereogram image out of it on real Amiga computers without turbocards! {be warned}
You can stop the the process by pressing and holding Q & N keyboard keys.
It's AGA application and therefore you need AGA Amiga {or compatible} and it MUST be
Flash-Gordon-Style fast or faster! The faster the better!
Resolution: 640 x 512 pixels {interlaced}
Docs, Libs and Font included {you must copy them to WB Fonts:,Libs: folders}

I have no real AGA computers, but one guy reported how it took an hour to render the stereogram picture with Blizzard 68030/50MHz CPU!?
On my side I was just happy that it did work on a real Amiga Hardware in first place!

These Amiga-Bytes made AGA version possible: https://aminet.net/gfx/3d/3Dots.lha
I found it so cool that i just had to start up BlitzBasic and extend the 3Dots version to what you can see here. I am still *working {that means it is to 95% finished} on it and that is why the source code isn't available.
However, you can use 3Dots.lha source code to create your own version, just like i did.
If you don't need AGA to create stereograms then probably the original 3Dots would be better choice for you.

*That was 2022/23 statement and opinion. In the meanwhile i am more 8-bit focused!
*I am thinking now if i should finish the remaining 5% or take that part out because then it would make it be 100% finished and i could give the source code away... thinking... thinking... hmmm!
