How export scene i threejs and see it in model-viewer

I need to export my Scene in threejs and see it direct in the next page by pressing a button… Can anyone help me with it.
Thank You

three has a gltfexporter, export, load in model-viewer. although … it seems odd, model viewer is based on three, it’s just a camera, a light and an environmentmap. wouldn’t it be way less trouble to just show your scene with the threejs you’re already using instead of loading in another?
