I'm selling my house and discovered that the options in Austria are either boring (just pictures) or expensive.

So I

- rented a Theta camera and took pictures of every room + outdoors

- made up a DSL to define a grid with connecting rooms

- used that to generate scenes for Pannellum (which I tweaked a bit)

- made some clickable svg maps (strangly this was not as easy as I thought)

- and put a bit of bootstrap over it

You can view the result here: http://kaufmeinhaus.at

Pannellum is great btw, see https://pannellum.org

Let me know if you are interested and I'll try to put the code on github.
