[x3d-public] HAnim Winter and Spring: some progress

Sun Sep 17 10:07:19 PDT 2023

thanks Andreas. Good to hear that the event utilities are supported. I will update the warnings in the X3D to X3DOM stylesheet to no longer flag those occurrences.

Joe, I saw similar white cubes around the finger joints when playing back in view3Dscene. Perhaps these are the extraneous invalid shapes that you have included inside the HAnimJoint nodes.

Thanks for sharing.

It turns out that none of the event utilities are listed in the x3dom
documentation pages due to an oversight in the documentation
generation but they are all supported.

I looked at the Leif model and the problem it exposed was a limitation
of the number of parameters (65536) a function can accept in the
underlying javascript engine. The texcoordindex array is too large for
the Math.max function which is used. There is a simple alternative.
With that, the animation sequence works but shows graphical artefacts
including white cubes.
