This approach takes a copy of the page and puts it inside a 3d context (three.js) to then simulates the page scroll to seem like a 1:1 copy of the paint layer of the browser. The post goes through the two approaches and shows a demo of liquid glass.
The implementation of glass is rather basic, but with the access to the whole paint layer, anything else can be added to it (PR welcome!)
The claims of something revolutionary that require Apple hardware or expertise were becoming tiresome.
There is no way (for now) to make something like it with pure web technologies, I was initially hoping that with the Houdini API it would be possible, but it seems not. It would be a really cool addition though
