[X3D-Ecosystem] Castle-model-converter HAnim glTF to X3D

[Don Brutzman]

Nobody has done a mapping between GLTF avatars (apparently still at work in
progress) and X3D HAnim.   So writing a converter without having a design
doesn’t seem very sensible. First things first, please. When GTF is stable
and ready, that will be good work for HAnim working group to consider
together.

all the best, Don
