Can Unity3D be used to create 360 ​​panoramic tours?

Question

3D

I am creating 3D virtual tours for residential and commercial premises and until recently I did it according to the classical well-known scheme - I photographed the premises from several points with a panoramic head on the fisheye, then stitched the panorama and then assembled all the finished panoramas into a tour. Recently, I found people from Canada who started to provide a service for creating similar tours, but they look a little different! The point is that they photograph absolutely the same, only they make much more points in the room so that you can move along them more smoothly, but otherwise it’s a complete mystery - no one knows how they process panoramas and make them such tours! What's new: you can move around the panorama with arrows like in a video game - when creating regular 360 panoramas, you need to move by clicking on the next panorama pointer, there is also a floor plan of the room with reference as a map - that is, when you move around the panorama, the position on the map also changes and you can move between rooms simply by clicking on the map. What is interesting is that when I first included this tour I was asked to download the Unity web player, so I thought if a similar task could be carried out in this program - that is, creating a similar first-person walker in a room created based on 360 panoramas? Below is a link to their panorama for clarity - What is interesting is that when I first included this tour I was asked to download the Unity web player, so I thought if a similar task could be carried out in this program - that is, creating a similar first-person walker in a room created based on 360 panoramas?

A bit like what Google does with their maps but also faster and more real!! Thanks for any help!
Update! Just read the information that panoramas they link to each other using photogrammetry!

Answer 1

this is definitely not Unity .. the unit now has a very long startup load .. (, and they work very poorly with memory
