Open 0xr.space, press Open and choose the Data folder of the tile set. Every tile is read in the browser and its levels are followed down through PagedLOD, with the photo textures, so a drone survey becomes one textured model you can walk around in the room on a Quest. A single .osg, .osgt or .osgb scene opens the same way, with its textures chosen alongside.

To stay drawable on a phone or a headset, the finest levels are read until two million triangles and the app says when it stopped there. Survey coordinates far from the origin are moved to the centre, and Z up becomes up. Textures in .rgb, .tga or .dds, particles, shapes, lines and points are not read, and a skinned model is shown in its bind pose.

## Steps

1. Copy the tile set's Data folder, or the .osg scene with its textures, to the computer, phone or Quest.
2. Open 0xr.space in the browser, or the Model Explorer app on a Quest.
3. Press Open and choose the folder, or the scene file with its pictures.
4. Press View in your space to put the survey on a table, or scale it up to walk through.

## Questions

### Why is it less detailed than in the capture software?

Levels are read until two million triangles so a phone or headset can draw it. A smaller area, or a coarser export, shows its finest level.

### Do I need to convert to 3D Tiles or OBJ first?

No. The .osgb tiles are read as they are.

### Can I stand in the survey at full size?

Only up to 10 m on its longest side, since a model is held between 10 cm and 10 m. A larger survey stays scaled down, which suits a table.

### Is my survey uploaded?

No. It is read on the device, and nothing is sent to a server unless you create a share link yourself.
