What is in this file
A single mesh of 3,136 vertices and 6,050 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.

| Triangles | 6,050 |
| Meshes | 1 (terrain) |

Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |
Use this file for
- Checking email size handling
- Checking loaders with embedded and external buffers
- Verifying axis and unit conversion from other formats
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 100 KB?
- Yes. It is 102,400 bytes, which is 100 KB in the binary units that operating systems and server limits use (1 KB = 1,024 bytes).
- What is inside the 100 KB glTF file?
- A single mesh of 3,136 vertices and 6,050 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.
- What does the sample model look like?
- A gently rolling surface, like a patch of terrain, built from indexed triangles. It carries vertex positions only: no normals, materials, textures or animation.
