glTF extras: Speakers and Blender Object Types addon
This addon exports Speakers data and Blender Object types into extra fields of a glTF.
extras are custom fields you can write into the glTF. They will mean nothing for a official, standard glTF importer.
To actually make use of those data, a parsing function must be coded in the importer, I’ll provide a sample method for three.js, that’s the environment this addon was built for.
THOSE ARE NOT NATIVE glTF FUNCTIONALITIES, NOR THIS ADDON WILL ADD ANY FUNCTIONALITY TO glTF FILE FORMAT
This addon can also export Blender objects types names as extra fields in the glTF file. This may be useful to distinguish between placeholder objects, or whatever use you may think of.
