3D interactive is the best way to showcase your products or places. So to increase in conversation. The user no need to wear 3D glasses. When he opens this page, he feels the 3D experience. Definitely, this will increases the time spent per user. When you allow the user to interact with your web content, this makes the user feel better.
These types of wonderful web designs increase your profit more than you think. My profit increased 922% after redesigning this website entirely.
So I highly recommend you to give more importance to UI (User Interface) on your website.
