WebApr 18, 2024 · glTF stores the actual mesh data in a binary chunk. This can be delivered a number of ways: As a separate .bin file, as a base64-encoded blob inside the JSON, or as a binary section of a .glb file. Each accessor points to a bufferView, and typically each bufferView references a buffer with a single binary data blob.
