Anyone who wants to look at a flat or an office floor should be able to walk it without needing an appointment for it. You film the rooms once with your phone, and out of that comes a walkable tour in which every distance is a distance in metres.

Each of them saves exactly one thing: a trip somebody would otherwise make twice.
One link, one click, and whoever is interested in the space is standing in it — no app, no account. What they see is the same rooms everyone else sees, not a selection of eight photos with the hallway missing. For you that means fewer viewings that are over after two minutes.
Does the sofa fit along that wall, how high is the sill, how wide is the doorway for a wheelchair? Because the delivery is metric, that gets measured in the tour instead of estimated on the phone. Whoever only holds the share link may measure too; changing the scale is reserved for whoever owns the capture.
Handover, refurbishment, move-out: a walkable state is harder to argue with than a line in a schedule, because it shows the whole room and not the spot somebody photographed. Because you walk through once instead of filing forty separate shots, what is left at the end is a state and not a folder.
Five steps, and at the third nothing is computed yet: the capture is checked before a GPU starts.
Walk slowly through the room, with the 0.5× ultra-wide lens.
In the browser, in parts straight to storage; it resumes after a dropped connection.
Frames and camera path are checked before a GPU computes.
Splat and collision mesh are built on a GPU; you see where it stands.

Flats are tight, bright at the window and dark in the corners, and they are full of glass and mirrors. Three rules from the guide are the ones it fails or succeeds on here.
In a bathroom or a hallway you cannot get three metres away from the wall. At 0.5× the room still fits in the frame and two consecutive frames overlap enough; at 1× you are filming wallpaper.
Best is 0.5×: 1.47 px loop error measured, while the same walkthrough stayed unsolved at 1×. 1× works too — another recording solved at 18.7 px — but it is riskier: less overlap, so walk slower; in bare rooms and narrow corridors the path can break. Do not use tele.
A window is brighter than anything else in the room. If exposure follows along, the room goes dark the moment you look towards the window, and the reconstruction sees two different rooms. Lock exposure and focus in the darker part of the room.
Set the AE/AF lock before you start — and do not film into the sun or a window.
A flat is a chain of rooms and the doors are its links. Pause briefly in every doorway and show it from both sides, or the rooms will not hang together in the model. Mirrors and glass doors stay the hard parts: keep a frame or an edge in the shot.
Show every passage twice — from both sides — and on white, featureless walls keep an edge in the frame.
Not a link to a platform but files that fit into your own software. Each carries its scale inside it: one unit is one metre, and the floor is down.

Furniture even gives the reconstruction something to recognise. What is awkward is anything that moves: a curtain in the draught, a door swinging shut, a pet following you around. Whatever moves during the walk ends up in the model as a smear.
Everything you film is in the model. Put away or close whatever nobody should see, and film with no people in shot. Individual spots can be removed in the editor afterwards, but that is handwork — tidying up first is easier.
Yes, and the rules are the same: you walk through instead of panning, and you split large floors into sections. What holds for a flat holds for a storey with thirty offices as well — you just film it in several walkthroughs.
Yes. Append “?embed=1” to the share link and the scene shows no header of ours, so inside your page it looks like your page.
