hi all.

im sure you have all seen the incredible work of JP Metsavainio and most specifically how he turn his beautiful pictures into 3D animation based on scientific data https://astroanarchy.blogspot.com/search/label/animations?m=1

Im really interested in researching and learning about the process of doing that. JP breakdown the basic idea behind his process in his blog but I’m wondering if there are any other resources/tutorial I could study myself to learn how to do this? I know Eric Coles and some of you has attempted this.

i understand that it is an incredible amount of work with many different steps, but if anyone could point me in the right direction that would be greatly appreciated.

That is some fantastic work. I can see why you would like to undertake this.

Well Written Respectful

Interesting. Was wondering when the tech had some traction. A very intriguing development to use software to represent 2d data. There is, however, science.
No way to really know til we have that, like we do in several ways in our system, but not actual.
Very much like it, has several applications, and in a great way.
The more true facts from what we know, entirely, the more accurate the model is.
Creating a model like that is a science itself.

That's great. In Pixinsight you can actually use the GAIA catalogue for photometric calculation... I'm pretty sure that is what JP does

I know that Dylan O'Donnel did this tutorial on 3d astrophotography, inspired by J-P Metsavainio's work.
it's far less scientific (or actually.. not scientific at all),

It creates the 3d effect by warping parts of the nebula and offsetting 2 layers + offsetting some stars.
Then switching back&forth between the layers to "fake" the 3d movement in the image.

I'd love to be able to create 3d videos like this though...

But I wouldn't have a clue where to start with those 3d-mesh.- I guess you could do the method that Dylan uses, but create like 10+ layers, all slightly more offset than the other, and then create a gif with 10 frames instead of only 2, to create a smoother version of it. - but again, nowhere near scientific. And it wouldn't create full spinning videos.
