A little more work on my custom stereogram (magic eye) python node for ComfyUI. There seems to be an optimal ratio for the image size to the pattern size, but I'm not sure exactly what that is yet. Feels like I'm getting closer though.

Here's Crater Lake, and the depth map it came from. If your eyes are able to get the 3d effect to converge, you should see an exaggerated z-scale of the topography/bathymetry.

A green to navy gradient with grainy noise. At the right focal distance, a 3d top-down view of crater lake's elevation emerges.

@awilbert had a bit of a hard time catching it on my phone, but after that, very pleasing, the depth variations feel very detailed, much better than the common 2d layers feund in such images.

@tshirtman It's much easier for me on a large screen too. But I found I can zoom way in on my phone where it's easier to resolve, then once my eyes are locked I can pan/zoom slowly without losing it.

@awilbert haha, wow, didn't think zooming would "work" but indeed if slowly i can keep the focus, and the depth impression is even better, i think it's the best experience i had with such images yet. Nice!
