All Good Andreas, the skeleton does sort of go along with
Basic X3D Examples Archive, Medical, Body Skin Indexed Face Set NIST (web3d.org)
It is fairly easy to make joints for the bones into a very nice and complete fully animatable ‘standard’ skeleton from hanim annex A example

and
https://www.youtube.com/watch?v=wV0B7SZr2_U
but hooking up this very detailed skin, being authored in very fine orderly points best orderlyness, including some nicely modelled surface feature reference locations, and the fine accessories (teeth and eyeballs, even) has been patiently waiting for a complete hookup. So, I see from color per vertex

points are very nicely organized for Hanim skeleton Joint skinCoord index and weight to skin geometry point index but …
Thanks and Best,
Joe

Has precomputed normals. The author defined normals rather than using the default browser computed normals.
Sorry I never published my computing/animating of normals for JoeKick.
Thanks,
Joe

Hi Joe,
Thanks for responding. I was looking for a Normal node in the JoeKick
example here:
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Characters/JoeKickIndex.html
Do you have another pointer to the example which may have the normals ?
Happy holidays,
Andreas

I guess the defensive tests may be in SavageDefense. Should we do some examples that can break typical parsers and validators, so browser developers can get more comfortable with their systems? Could this be added to the ConformanceNist examples?

Here’s my current list of examples, from a previous message starting with “Status”. https://coderextreme.net/X3DJSONLD/src/main/html/codex.html. The message made assignments as I saw fit, but I encourage you to go through your assigned list, I believe I am pointed at development or recent releases of X_ITE and X3DOM.

How can we defend ourselves, and what limits can we set in place? I do know tail recursion can help, but I’m not sure what happens when there are too many stack frames to open.
