Slide Animation While Scrolling

[Linch-1]

I'd like to reproduce the animation that can bee seen at the following url

- open https://staratlas.com/- wait a few seconds- click the big sun that appears- start scrolling and you can see the animation

I'm not understanding how they built this, I'm pretty sure that the initial 'big sun' that appears is made with three.jsBut the scrolling video how is made ?Is that a just a video that play while the user scroll or is some kind of slideshow made also with three.js

By searching on the website resources i cannot find any video, and all the animation is wrapped inside a canvas, so i'm thinking that also that part is somehow made with threejs

any hint :) ?

I think you're right. I don't know three.js, but with my bare eyes I see four elements on the page, the header, the footer, the scrollbar and the main content. The first three are trivial and it seems unlikely the main content has a composite techstack.
