The six-step capture

  1. Step 1

    Pick a splat-capable app

    Install one of the apps below. Make sure you choose its Gaussian Splat (or 'Splat') capture mode — not Photogrammetry or NeRF mesh. Splat exports look the most photoreal in your tour.

  2. Step 2

    Prep the space

    Open every blind and turn on every light. Even, diffuse light beats bright sun. Tidy clutter, hide cords, remove pets, and ask people to step out — moving objects create ghosting.

  3. Step 3

    Walk a loop, not a line

    Start at the front door. Walk a continuous loop around each room, hugging the walls. End where you started. The capture needs to 'close the loop' to align cleanly.

  4. Step 4

    Film slowly with overlap

    Hold the phone at chest height, screen facing you. Move at a slow stroll — about half your normal walking pace. Each step should overlap the previous frame by 70%+. Pan, don't whip.

  5. Step 5

    Process & export .ply

    Let the app process in the cloud (a few minutes for a room, up to an hour for a full house). Export the file as .ply or .splat to your phone's Files app.

  6. Step 6

    Upload & share the link

    Open walkthrough.world on any device, drop the file on the homepage, and you'll get a /tour/ link. Send it to anyone — they walk through it in their browser. No app, no login.

How long it takes
Single room
1–3 min capture·~30–80 MB
Apartment (3–4 rooms)
5–8 min capture·~150–250 MB
Full house
10–20 min capture·~250–500 MB
Exterior + yard
5–10 min capture·~100–200 MB

Cloud processing in the capture app adds another 5–60 minutes after you stop filming.

Lighting & best practices

Do
  • Even, diffuse daylight (cloudy days are perfect)
  • Slow, steady, continuous motion
  • Capture every corner from multiple angles
  • Mirror surfaces? Cover or skip — they confuse the AI
  • Keep the phone level — avoid extreme tilts
Avoid
  • Direct sun pouring through one window
  • Stop-and-go filming or jerky movements
  • People, pets, or curtains moving mid-scan
  • Reflective floors without a rug or two
  • Filming through glass doors or windows
