How was this built?

Can anyone shade some light how was this website and platform built?

It looks like they used Shapespark mixed with some other platforms?

It’s just a couple of 360 panoramas. As you can see, you can only zoom in and out of the image; you can’t interact with it or walk through the spaces so it’s not Shapespark definitely but they could possibly use Shapespark to render images.

Makes sense to be only 360 images, i was confused with all the menus and everything going on there, annoying but i only wanted to see how its made as I’m exploring all the possibilities.
You can see shapespark Avatars on some pages.

Based on what gets loaded, its 3DVista;
