[x3d-public] Diamond Main 0, first looks:

Wed Nov 1 10:26:37 PDT 2023

Applying Andreas' x3dcf.py
https://github.com/andreasplesch/x3d-python-mod/blob/main/x3dcf.py to
DiamondManLOA0.py,

basically doing:

from x3dcf import *

instead of

from x3d import *

After editing output from DiamonManLOA0.py as well, see attachments.

Here is output from tovrmlx3d.exe

~/Downloads/view3dscene-4.3.0-win64-x86_64/view3dscene/tovrmlx3d.exe
--validate DiamondManLOA0.x3d
tovrmlx3d: Warning: X3D: Incorrect USE clause: node name
"hanim_humanoid_root" undefined (possibly the USE clause appears before the
DEF for this node name)
tovrmlx3d: Warning: X3D: Incorrect USE clause: node name "hanim_sacroiliac"
undefined (possibly the USE clause appears before the DEF for this node
name)
tovrmlx3d: Warning: X3D: Incorrect USE clause: node name "hanim_pelvis"
undefined (possibly the USE clause appears before the DEF for this node
name)
tovrmlx3d: Warning: HAnimHumanoid.joints list was empty, fixed to list all
2 joints
Exception "Exception":
Validation failed (consult the warnings above), exiting with non-zero status

I'm guessing before looking at the file that USE is coming before DEF.
Indeed a quick grep reveals USE before DEF:

$ grep hanim_humanoid_root DiamondManLOA0.x3d (output, not input)
      <HAnimJoint containerField='joints' USE='hanim_humanoid_root'/>
      <HAnimJoint containerField='skeleton' DEF='hanim_humanoid_root'
center='0.0 0.824 0.0277' name='humanoid_root'>

But if you look at the original python, the USE and DEF are the other way
around:

$ grep hanim_humanoid_root DiamondManLOA0.py

HAnimJoint(DEF='hanim_humanoid_root',center=(0.0,0.8240,0.0277),name='humanoid_root',ulimit=[0,0,0],llimit=[0,0,0],
      HAnimJoint(USE='hanim_humanoid_root',ulimit=[0,0,0],llimit=[0,0,0]),

What's going on?  x3d.py/x3dcf.py  is reordering the fields, against author
intent.  There are also extra fields, ulimit and llimit placed in the USE
node in the by X3dToPython.xslt. See original x3d:
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Templates/DiamondManLOA0.x3d
compare to python generated:
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Templates/DiamondManLOA0.py
<https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Templates/DiamondManLOA0Index.html>

Even if X3dToPython.xslt is fixed to not put extra fields in USE nodes,
there will remain the question of DEF/USE ordering.  I have patched this
skeleton/joints in my X3duomToX3dPythonPackage.xslt <http://nowhere> (not a
link), and I am offering it.  I will be able to provide a real link
relatively soon.
