This is not a stereoscopic gif. I’m pretty good at seeing these both crossed and uncrossed varieties. This is just the same image with the middle image reversed. Is anyone getting a good stereo effect from this, it seems unlikely this complex image would work out to just be reversed to create a 3d effect.

Edit. I thought about some more and think the images are perhaps rotated 90 degrees from proper orientation for 3d. Given the skinny nature of the images, perhaps they could be redone with a crossed image on top and an uncrossed image below. It would also seem likely the original would portray the orbit horizontally.

Edit 2. Back to thinking this is just the same image but reversed in middle. Original article shows image horizontally, but only one. Perhaps OP thought this would somehow create 3d.

I edited out the centre. I don't think it helps.

I can make it three but doesn't look 3d

Make it 5 panels (harder cross-eye). The middle one then becomes really clear and appears 3D.

Your two panels here are the same image side by side (whereas the cut out center panel was mirrored). This gives an illusion of depth because of the position that your eyes are relative to the rest of your surroundings, on top of some visual artifacting created from copying or exporting as a gif. For my gif you should only see 4 panels total while crossed, including periphery. It is pretty tricky to see

edit: To clarify I recommend thinking of this GIF as data visualization in a stereoscopic medium, where the depth illusion is created by reflected symmetry, and not the usual parallax stereograph, where two pictures are taken of the same object from slightly different angles. Stereographs usually use parallax, but not always, sorry for the confusion!

I get the feeling that you know a lot about black holes and very little about how stereoscopic images work.

It may not be stereoscopic parallax, but I do make these to be viewable with stereoscopes so it is stereoscopic by definition, if that's what you mean

I like how you proved them right by trying to explain yourself

It's more that there generally isn't a well fitting word for what I'm doing. "Stereoscopic" is the closest, though; "noting or pertaining to three-dimensional vision or any of various processes and devices for giving the illusion of depth from two-dimensional images or reproductions, as of a photograph or motion picture."

It accurately conveys the medium, viewing method and the intended subject, which is the symmetry. As long as I get those things across

Except there is no illusion of depth here, thus not stereoscopic by your own referenced definition. It being able to be viewed through a stereoscope doth not stereoscopic make.

I agree I don't think this is stereoscopic. I'm also not sure why there are three. I tried everything I could think of.

This is exactly what I’m seeing. It makes sense, in a very intuitional way….but it’s hard to focus.

Edit: I seemed to achieved it. Cross until you see 5, not three. The middle get the 3D quality

You are correct that this is reversed/mirrored in the center. I have 3 panels so that both cross-eye and uncross-eye are visible at one time. There should be 4 panels total when crossed correctly, two opaque in the middle and two "see through" panels in the periphery on either side. It is tricky to see for sure.

The reasons why I mirror these have to do with symmetry of lensing, where the same image appears on opposite sides of the lens with black holes, as well as the mirroring effect with strong gravitational lensing, where galaxies can be seen as mirrored smears, sometimes multiple times.
