Data volume of the Tokyo track
The figures below describe the content of the track Brio in the data, not what any tool built from it does. They come from
recorded censuses and exports of a build that is no longer installed. Observed

Triangles per area
Section titled “Triangles per area”Triangles that draw in the main view in a box of the Tokyo core (placements and terrain), at the LOD named: Observed
| Area | LOD0 | LOD1 | LOD2 |
|---|---|---|---|
| 700 m box | 63.7 M | 46.1 M | 30.3 M |
| 512 m box (Tokyo) | 14.4 M | ||
| 1.2 km Shibuya box | 183.7 M | ||
| one Shibuya tile at LOD2 | 40.1 M placed triangles (12 tiles ≈ 480 M) | ||
| 450 m section at LOD1 | 17 to 19 M | ||
| Horizon Festival area | 22.3 M |
The Tokyo downtown contains 1,916 building proxies (distance levels) of 6.3 M triangles in total. Observed
Materials of an area
Section titled “Materials of an area”In one Tokyo core area 6,059 materials resolve, 6,052 of them to exactly one shader variant. Observed
LOD pitfalls in the data
Section titled “LOD pitfalls in the data”A LOD file can change the material set or UV atlas of its template, so a lower level is not always a drop-in: bikes, fences, railings, grates and chain-link have alpha-cut parts, and the LOD1 of a bike rendered zebra-striped with the LOD0 material mapping. Vegetation and props under 2 m reduce to LOD1 without visible loss at street level (a 512 m block went from 18.4 M to 11.9 M triangles). Observed
