Sample datasets
Every process in Neurones 3D can be tried without data of your own. The demo scenes are generated inside the app on the spot, so there is nothing to download.
Built into the app
Open . Each scene is generated when you pick it.
| Scene | Good for trying |
|---|---|
| Indoor room (point cloud) | Indoor classification, decomposition, meshing, measurement |
| Terrain city (point cloud) | Ground filter, terrain products, the Outdoor model |
| Powerline corridor (point cloud) | The Powerlines model and instances, height above ground |
| Streetscape (point cloud) | The Streetscape model |
| Factory pipework (point cloud) | Cylinders in the decomposition |
| Sculpture (mesh) | Mesh display, conversion to a point cloud |
Under Two clouds at once:
- Two surveys of one site (compare & detect change): a 2024 and a 2026 survey with a building demolished and one built, a 120 mm and a 10 mm settlement patch, and a stockpile grown by 1.5 m, with 8 mm of noise, so the level of detection is about 15 mm. Try M3C2 on it, and a volume on the stockpile.
- Full scan + labelled subsample (transfer a column): a one-in-twenty subsample carrying a classification, to carry across to the full scan.
Public data the numbers were measured on
The figures on this site were measured on data anyone can obtain, so they can be checked.
- S3DIS, Area 4: an indoor laser scan of about 43.5 million points from the Stanford 3D Indoor Scene Dataset. The indoor classifier, the decomposition, the scene graph and the floor plan figures use it. Available from its publishers under their own terms.
- IGN LiDAR HD: France's national aerial LiDAR programme, published openly by the Institut national de l'information géographique et forestière. The ground filter's F1 of 90.3 % was measured against a tile's own production ground class, and the Outdoor model's 86.2 % against held-out tiles.
Customer data never appears on this site, in a figure or in a number.
