[x3d-public] HAnim Examples

Sat Apr 25 20:02:01 PDT 2020

JSON translation of annexdA.x3d:
http://dug9.users.sourceforge.net/web3d/tests/hanim/annexdA.x3d

X3D JSON looks like:

      "-skeleton": {
        "HAnimHumanoid": {
          "@DEF": "hanim_AnnexD01Jin",
          "@info": [
            "humanoidVersion=2.0"
          ],
          "@name": "AnnexD01Jin",

In my mind, the -skeleton goes inside the HAnimHumanoid, but defer to
experts.
See X3D XML:

<HAnimHumanoid DEF="hanim_AnnexD01Jin" info='"humanoidVersion=2.0"'
containerField="skeleton" name="AnnexD01Jin" scale="0.0225 0.0225 0.0225"
version="2.0">

Why the containerField????

Thanks,

John
