We rebuilt the FreeGaussian 3D viewer from scratch. Every scene you process with us now opens in a viewer that lets you walk through it like a real visitor, look at the 3D mesh behind the splat, measure distances in metres and check what the capture looks like — while staying smooth on phones as well as on desktops.
Here is everything that is new.
First-person walk through a courtyard captured at real-world scale.
Exploration
Walk at human scale
In scenes with metric scale — the ones you get from a raw Insta360 .insv, where the camera's motion sensors give us the true size of the room — you now walk like a person: eyes at 1.65 m from the floor, at the pace of a normal step (1.4 m/s). The viewer follows floors, ramps and steps, so going up a staircase feels like going up a staircase.
Collisions
Walls and furniture stop you: instead of flying through a wall you slide along it, the way you would in a game. Low obstacles, under 50 cm, are stepped over, so a door sill or a rug never blocks you. If you prefer to fly freely, collisions can be switched off in the settings.
A smart starting point
A visit no longer starts with your nose against a wall. The viewer picks the point with the most open view near the start of the capture, and always opens with your gaze level with the horizon.
Adjustable speed
One button cycles through three walking speeds — 0.5×, 1× and 2× — for slow inspections or quick walkthroughs.
Viewing modes
Mesh mode
Next to the Gaussian splat, every scene now carries a 3D mesh of the same space, and the viewer can show it directly: as a wireframe, to read the geometry, or with its photographic textures, as a lightweight 3D model.
Mesh mode: the reconstruction as a 3D model with photographic textures.

Floor grid
In metric scenes a 1 m grid can be laid on the floor: a quick way to read the size of a room at a glance.
The settings panel: metric scale, 1 m floor grid, camera path, collisions and quality.
Capture path
The viewer can draw the trajectory of the person who filmed the scene, coloured from start to end, together with the position of every shot. It is the fastest way to see how a space was covered — and where a capture could be improved.

Adjustable field of view
The field of view can be tuned to taste, from a narrow, telephoto-like view to a wide one. The default is 80°.
Measurements
- Distances in metres. Click two points to measure the distance between them. The ends can be dragged to adjust the measure precisely.
- A list of your measures. Every measure appears in a list, where it can be selected or deleted.
- Hidden measures. A measure covered by an object turns dashed, so you always know which ones you are seeing through a wall.
The gate of the courtyard: 4.33 m wide, 2.95 m tall. Click two points, drag the ends to refine, manage everything from the list.
Quality and performance
- Auto quality. Full definition when you stand still, a lighter rendering while you move. If your device struggles, the viewer lowers the number of Gaussians on its own to keep things fluid.
- Manual quality. Four fixed levels, from Low to Ultra, for when you want full control.
- Built for phones. A lighter load on mobile devices, and a fix for an iPhone Safari issue that could leave already visited scenes black.
Auto or manual quality: four levels, from Low to Ultra.
Scene information
A new Info panel tells you everything about the scene: whether the scale is metric, which camera was used, how many photos and points went into it, the mesh data and the performance of your device.
The Info panel at a glance — this courtyard was shot with an Insta360 X6.
For scene owners
If the scene is yours — or you manage it as an admin — the viewer has an Edit mode:
- Move, rotate and scale the scene with a 3D gizmo, or type exact X/Y/Z values. The floor grid helps you align it.
- Choose the starting view: decide exactly where the visit begins.
- Saved for everyone: your adjustments are stored with the scene, so every visitor sees it already aligned.
Embed it anywhere
Each scene also has an embeddable version, read-only and without editing tools, ready to drop into a website, a listing or a portfolio.
Try it
Process a scene — ideally from the raw .insv of an Insta360 X6 or X5, to get metric scale, walking and measurements — and open it in the new viewer. Upload your capture to get started.
