Documentation for binary file

[adius]

Is there any documentation on the structure of the binary file.
I want to create it from mesh data, but have no idea where to get started.

As long as byte alignment is correct (see #167), the binary file can be laid out any way the tool generating it wants. In the glTF JSON, bufferViews point into sections of the binary data (and accessors point into bufferViews) so this is what defines the layout, not the glTF spec itself.
