3D virtual tour example: a two-storey townhouse
A furnished townhouse of 77 viewpoints spread over two floors, stairs included. It is the counter-example to the flat: here a 360-only capture holds up almost perfectly, with 71 viewpoints attached out of 72.

The property
A furnished townhouse over two floors joined by a staircase. 77 viewpoints in the Visites-virtuelles survey — more than double the flat, for a path that has to stay continuous from one floor to the other.
This is the property that tests two things the flat does not: vertical continuity, and how the process holds up on a furnished, varied volume.
What each format gives, here
Hybrid and backup — all 77 viewpoints, across both floors
Survey geometry, every viewpoint placed, the staircase walkable both ways. In the dollhouse view the two floors read one above the other: that is where the difference with estimated depth becomes obvious, because a misplaced floor slab makes the storeys interpenetrate.
Visites-virtuelles link — positions hold, depth is estimated
All 77 viewpoints are placed and correctly spread over the two floors, since their positions come from the original survey. What degrades is how crisp distant volumes look: in the larger rooms and the stairwell, far surfaces are approximate.
360° only — 71 out of 72, and that is the good surprise
Mind the denominator: the 360-only version does not start from the 77 Visites-virtuelles sweeps but from a separate 360 capture of 72 panoramas. Of those 72, 71 were attached — a single viewpoint stayed isolated.
That is the exact opposite of the flat, and for a precise reason: this house is furnished, colourful, cluttered. Every shot sees distinctive objects that the next one finds again, so the reconstruction never gets lost. It is not the size of the property that decides, it is how visually rich the decor is.
What makes a capture hold up or fall apart is detailed in how to create a 360° virtual tour.
| Format | Viewpoints placed | Geometry | Colours | Price |
|---|---|---|---|---|
| Hybrid | 77 / 77 | Visites-virtuelles survey | Original rendering | €69.38 |
| Visites-virtuelles backup | 77 / 77 | Visites-virtuelles survey | Rebuilt | €55.50 |
| Visites-virtuelles link | 77 / 77 | Positions + estimated depth | Original rendering | €74.93 |
| 360° only | 71 / 72 | Photogrammetry + estimated depth | Your photos | €60.95 |
Prices computed with the live grid — the "360° only" row covers 72 panoramas, the others 77. Detail on the virtual tour pricing page.
What this example proves
A furnished, varied property reconstructs very well from 360 photos alone, even over two floors and even at 72 viewpoints. Compared with the 45 m² flat that drops to 17/29, the conclusion is clear: what matters is not floor area, it is what the photos have to recognise. An empty, plain interior is the hard case; a lived-in one is not.
Frequently asked questions
Why 72 panoramas here and 77 viewpoints elsewhere?
Because they are not the same captures: the "360° only" version comes from a separate shoot with a 360 camera (72 panoramas), while the other three start from the Visites-virtuelles survey of the same property (77 viewpoints). The property is the same, the source is not.
Does a staircase cause trouble for the reconstruction?
It does if you skip it: two floors with no intermediate shot share nothing, so nothing links them. Here the staircase was photographed on the way up, and the two floors attach without difficulty, including from photos alone.
Does the tour handle multiple floors?
Yes: viewpoints are grouped by floor, the plan switches from one storey to the other, and the dollhouse view shows both stacked. Open the hybrid version above and press D.
