Using scenes on a web page

Hallo everybody, this is my first time,
My site on gothic sculpture and architecture is creationofgothic.org.
My question could apply to over 800 buildings.
I want to display SU Scenes and allow the user to move around the model, as is normal in Scenes.
Do I need a copy of SU on the site, or is there something like…dae that I can use with an SU model.
.dae files will rotate etc on my web pages.
If that is an option, how do I acclimatize an SU file to one that can be used in DAE?

You can upload them on 3d warehouse and then use the embed functionality to place them on your own website.
