This model is best viewed by selecting the first person mode in navigation setting and slow speed (eg 0 or 1) and navigating at the neighborhood of the small gray cubes. It is computed from videos taken by head-held 360 cameras (Gopro Max) and walking during 21min. in Collonges-la-Rouge in France. The cubes indicate locations of the camera.

The main steps of the reconstruction method are in my publications: self-calibration (3DV‘15, CVIU‘17), structure-from-motion (BMVC‘07, IVC‘09), surface reconstruction (CVIU‘18 improved by IC3D‘19), curves are matched (PAMI‘02) and integrated in the surface, texturing (IC3D‘20), coordinate reset (IC3D‘21).
The original textures are divided by 3. The surface is simplified (edge collapses). The multi-camera model is non-central and global shutter.
