Looks very nice and gives a good overview of the building. Maybe you could show a list of rooms next to the model, so when you click one of these room names, the room is highlighted in the 3d model? Then it could also be useful for navigating the building.
Thanks for the nice words @haraball.
We totally forgot about something like a list of the rooms, this is a really good idea. We probably add it in the future.
I thought one would be able to walk the building, FPS-style. It would be a neat feature
We decided to make it the way it is now because we wanted to have it in the browser.
It is possible to walk through the whole school in Blender, the program we used to create the 3D model. However it couldn’t be that way because of browser limitations. There are sites like Sketchfab where you can upload a 3D model and walk in it but the school is too big for Sketchfab.
We started to upload and add just the different rooms.
