What Is a Virtual Tour?
A virtual tour is an online walkthrough of a real place, built from 360° photographs that are linked together. The visitor opens a link, lands inside one photograph, drags to look in any direction, and clicks a doorway or an arrow to move to the next one. It runs in an ordinary browser, needs no app, and — unlike a video — the visitor chooses where to look and where to go.
The phrase gets used for four or five different things, which is why the answer above is specific. A slideshow with music is not a virtual tour. Neither is a video of someone walking through a house, however steady the gimbal. The defining property is control: the visitor decides where to look and which way to go.
What it is made of
- Scenes — one 360° photograph each, covering everything around a single standing point, floor to ceiling.
- Hotspots — the clickable marks placed on the photograph. A link hotspot moves the visitor to another scene; an info hotspot opens a note.
- A viewer — the piece of software that wraps the flat photograph back onto a sphere and lets you drag it around.
- A link — the address you send. Everything above lives behind it.
Some tours add a floor plan with the scenes pinned to it, a contact form, or a background sound. Those are extras. The four items above are the whole mechanism.
How it differs from the things it gets confused with
| Who chooses the view | What it is built from | Runs in | |
|---|---|---|---|
| Photo gallery | Nobody — fixed frames | Ordinary photographs | Any page |
| Video walkthrough | The person who filmed it | A recorded path | A video player |
| Virtual tour | The visitor | Linked 360° photographs | The browser |
| 3D scan | The visitor | A measured model of the building | The vendor’s viewer |
| VR experience | The visitor | Either of the above | A headset |
The last row is worth separating out: a virtual tour does not require a headset, and almost nobody uses one. The overwhelming majority of tour visitors are on a phone, dragging with a thumb.
What a visitor needs
A browser. That is the whole list. On a phone the gyroscope can steer the view, so holding the phone up and turning around works like a window — but it is optional, and dragging does the same job.
No app, no plugin, no account
Anything that asks a visitor to install something before they can look at a room will lose most of them at that step. A tour that opens as a plain web page does not have that problem, which is most of the reason this format outlived the plugin era.
Where virtual tours are actually used
- Property listings — the biggest use by far. A buyer understands the layout before deciding to visit.
- Hotels and venues — rooms, the restaurant, the function space, in the order a guest would see them.
- Showrooms and dealerships — stock that is too big or too far away to show in person.
- Construction and site records — what the space looked like on a given date, before the walls closed.
- Schools, galleries and public buildings — an open day that does not expire.
How one gets built
Shoot one 360° photograph per space, upload them, link the doorways, publish. The detail — equipment, order of shooting, the mistakes that cost a reshoot — is in how to make a virtual tour. If you are doing it for a house, 3D virtual home tours covers what is different about residential listings.
