Which GSOCK packages for cloud shapes filters ?

[soleil]

In this showcase https://experiments.p5aholic.me/day/019/

we see cloudshapes, permanently changin, with colors and acting like optic filters to change the appearance of the background and the word "DIVISION".

I could extract few functions (below) the developer is using, but I would like to have more hints about how to achieve such result.
There are many things, however I would like to go to the essential:
- clouds (SVG) everchanging shapes
- clouds as optic filter with its color and effect

There is an effect of double cloud (we see the border twice), which is nice but I'm not interested by this.

Do someone give me few clues or an approximate explanantion of how to achieve this, with which packages ?

EDIT
After some investigation it seems it's not so much relying on greensock but Three/webgl. I might miss something though.

GSAP just animates stuff. To render stuff like that, you need to use WebGL. It looks like they are using three.js.
