What is in this file
A single mesh of 289 vertices and 512 triangles, with its vertex and index data embedded in the JSON as a base64 data URI, so the file needs no companion .bin. A "padding" string under the standard "extras" property brings the file to the exact size.
| Vertices | 289 |
|---|---|
| Triangles | 512 |
| Meshes | 1 (terrain) |
| Buffers | 1, embedded as a base64 data URI |

Where 10 KB matters
A 10,240-byte file that still arrives in the first round trip of a new connection. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| TCP initial congestion window | About 14.6 KB (10 segments) | A 10 KB response fits in the first flight of packets; the 25 KB sample does not. |
| nginx and Apache request headers | 8 KB per header line by default | Data this large must go in the request body. |
| webpack asset modules | 8 KB by default | Assets over the threshold are emitted as files instead of data URIs. |
Use this file for
- Checking thumbnail and icon handling
- Verifying axis and unit conversion from other formats
- Load-testing rendering with large meshes
Testing notes for glTF
- A file can declare extensions it requires, such as Draco mesh compression. A loader without that extension has to refuse the file.
- A .gltf file often refers to separate .bin and texture files. Uploading the JSON alone gives a model with no geometry. The samples here embed their data, so one file is enough.

Questions about this file
- Is this file exactly 10 KB?
- Yes. It is 10,240 bytes, which is 10 KB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
- What is inside the 10 KB glTF file?
- A single mesh of 289 vertices and 512 triangles, with its vertex and index data embedded in the JSON as a base64 data URI, so the file needs no companion .bin. A "padding" string under the standard "extras" property brings the file to the exact size.
- Do the glTF samples need a separate .bin file?
- No. The vertex and index data are embedded in the JSON as a base64 data URI, so each sample is a single self-contained file.
