Very nice skybox or sky background. It works well on small area at the mountain top. At the hillside it fails badly. Your interactive version seems to work a little better.
Maybe one day there will be a good way to great solid ground as well. So far HY-World AI generation is the best. And even it does not match the quality of rest of this kind of scenery.
Currently I must consider this model only as a panorama picture or somekind of 360 view. Very nice one as such. If the ground gets better, it would become true 3D model and very special kind of. That might be one potential directions that 3DGS could go.
