How to implement 3d travel?

Question

JavaScript

Hello. How to implement 3D travel on the site, how does it work in general? Please take a look here . Look, there you can choose day or night, you can watch everything in 360 degrees... just a question, how!? What is it, Canvas? I just found on their canvas sources... How can I implement something like this?

• What did they film it with?
  
• Is this a photograph or did you draw it yourself?
  

Thanks in advance!!
