also search for the H-ANIM spec on the X3D site (www.web3d.org) or since
that one is under changes at the moment, checkout http://www.h-anim.org

I'm interested in transcoding XODE <---> H-ANIM

X3D (VRML3.0) now includes H-ANIM if I remember well (it was a VRML2.0
extension)

> do checkout www.web3d.org (site is under reworking at the moment) for the

> VRML one and a binary encoding is under way
>
> VRML2.0 is an ISO spec and X3D is under ISO processes already

> cool I think
