Stereoscopic 3D moon made out of own data

In November 2021, I posted this: viewtopic.php?t=4832
It shows the distance variation and libration of the Moon. Back then I already wanted to make a stereoscopic version since there is a perspective shift. But it only gave weird results.
Fast forward to a week ago: I was going through some older captures and stumbled across this one also. And viewing it, I realized right away why it gave weird results: stereoscopics are based on a horizontal shift and not diagonally like in the above topic.
So I rotated the captures until the variation was horizontally and now it works
Of course it's not something one could see in real life due to the distances and size. But it's a nice effect nevertheless.
For those unknown with stereoscopics: https://en.wikipedia.org/wiki/Stereoscopy
I made 2 versions: a parallel (the 1st one) en cross eye (2nd one) version. It differs per person which one works, this has to do with how our brains process visual information. For me I get the good 3D result with the parallel. The cross eye gives a kind of "hollow" effect.
Easiest way to see it, is to cover your least dominant eye with your hand and focus with the other eye.
For example the left eye is covered. Now for the parallel version, focus on the right moon with your right eye or for the cross eye version, focus on the left moon with your right eye.
Once focused, remove your hand and let the images "flow" into/onto each other.
It can depend on a few factors like your distance to the screen, brightness of the screen, ambient brightness of the room, reflections on the screen (on a mobile device for instance), etc.
