page-wise scroll-position to 3D-camera position

I think this can be used in many contexts to create a more immersive experience.

the size of boilerplate code for this to run is ~500KB.
which is not too much.

three.js ~150KB
gltf loaders/draco wasm ~330KB
3D scene in glb/gltf ~30KB

(the size of the scene might differ strongly depending on its contents, details and textures)

here is an other example with a different model
