GLBLoader

Provides functions for parsing or generating the binary GLB containers used by glTF (and certain other formats).

Takes a JavaScript data structure and encodes it as a JSON blob with binary data (e.g. typed arrays) extracted into a binary chunk.

Functions

parseGLB(arrayBuffer)

Parses an in-memory, GLB formatted ArrayBuffer into a JavaScript "JSON" data structure with inlined binary data fields.

Parameters:

  • arrayBuffer (ArrayBuffer) - an ArrayBuffer to decode

Returns: Object

encodeGLB(json)

Writes JavaScript JSON data structure into an arrayBuffer that can be written atomically to file, extracting binary fields from the data and placing these in a compact binary chunk following the "stripped" JSON chunk.

Parameters:

  • json (Object) - json object to encode

Returns: ArrayBuffer
