<div dir="auto">Reorient should just change OrientationInterpolators, no changes to Humanoid figures. I am fairly dependent in which nodes I traverse right now hunting for interpolators, I can add more. DOM rescaling is not possible, because JinLOA4.x3d has a stack overflow which X3DJSAIL hides. Plus DOM is not really typesafe. In other words, I am not sure I do full traversal.

For applying transformations to an X3DJSAIL scenegraph, like rescaling Humanoids and changing OrientationInterpolators through the whole scenegraph. 3D Model is in X3DJSAIL-GraalJS, extending beyond limits of Java binding code size.

I’d like to thank Don Brutzman for X3DUOM, X3DJSAIL and X3dToJson.xslt (I can’t use CommandLine due to Java bug/stack overflow), Roy Walmsley for X3DUOM and X3D JSON Schema, the authors of JinLOA4.x3d, Java and JavaScript language developers, vim developers, Saxon developers, Python language developers and Git developers.

Rescaling takes a Humanoid with a scale field, and multiplies and adds the values down the humanoid hierarchy.

Reorientation currently negates the rotation, achieving a kind of satisfaction for converting +Z to -Z and vica versa for OrientationInterpolators. Negating any axis is also possible.

Thanks to Joe Williams for the inspiration, and to Andreas Plesch for showing it’s possible, and Katy and Carol for Gramps (not included).
