- Walkable means the viewer moves forward through the space, not just rotates in place.
- Format: a 3D scene rendered live in a browser — Gaussian splat, mesh, or hybrid.
- Why it works: the viewpoint changes as the viewer moves, the way it would in real life.
- Cheapest path: $99 once with TourReady, delivered from a short video in about two minutes.

The plain-English definition
A walkable 3D tour is a navigable 3D reconstruction of a physical space in which the viewer moves their viewpoint freely — stepping forward through the scene, not just rotating from a fixed point.
The keyword is "walkable." Lots of tools call themselves "3D tours." Many of them are actually a single 360 photo, or a series of linked 360 photos with jump-points between them. A walkable tour is something the viewer can actually move through, with continuous perspective change, the way a video game lets you walk through a scene.
Why "walkable" is the word that earns the click
The job a tour is doing is one specific thing: closing the gap between a stranger and the decision to walk in. A walkable tour does that better than every other interior format because it gives the visitor a sense of having already been there. The brain doesn't distinguish well between a remembered visit and a vividly explored 3D space — it just feels familiar by the time they arrive.
For a medspa, a dental practice, a fitness studio, or a vacation rental, that "I've already been there" feeling is the strongest pre-booking signal a website can produce.
"A 360 photo is a fixed viewpoint. A walkable tour lets the viewer move."
Three formats that deliver "walkable"
1. Linked 360 photos (Matterport-style "dollhouse")
The simplest form. Capture 360 photos at several points in the space, then let the viewer click between them. Each click jumps to the next viewpoint. It feels walkable but is actually a slideshow.
2. Polygon-mesh 3D model
Reconstruct the space as textured triangles. The viewer's camera can move anywhere. Built using LiDAR or photogrammetry. Heavier files; lower visual fidelity.
3. Gaussian splat
The current state of the art. The scene is millions of small colored 3D blobs that render photorealistically in real time in a browser. See our Gaussian splatting explainer for the full mechanics. This is what TourReady delivers.
Walkable 3D tour vs the alternatives
vs 360 panorama. A 360 photo is a single fixed viewpoint. A walkable tour lets the viewer move. See the full breakdown.
vs video walkthrough. A video moves along a path the videographer chose. A walkable tour lets the viewer pick their own path. Higher dwell time, higher control, fewer skips.
vs floor plan. A floor plan is a 2D top-down schematic. A walkable tour is a 3D scene. Both can be useful — the floor plan for measurements, the walkable tour for storytelling.

How to actually get one
Matterport. $300–$1,500 per capture session if you hire a Capture Tech, or $3,500 for the Pro2 hardware to capture in-house. Plus $99–$309 per month subscription. Tour goes offline if you cancel.
Polycam. $15–$40 per month with an iPhone Pro for LiDAR capture. You own the output files but you handle stitching and hosting.
TourReady. $99 one-time for a walkable 3D tour from a short video. Built on Gaussian splatting. Delivered as a hosted scene plus iframe embed snippet in about two minutes. Hosting is free for the life of the tour.
