[X3D-Ecosystem] reminder Blender X3D Support call Jan 7 2025

[John Carlson]

I’m hoping to get my bone animation and object animation XML exporter code
(ROUTEs,PositionInterpolators,OrientationInterpolators,TimeSensor and
ProximitySensor) tested tonight in my main git branch.

This will be a separate file from export_x3d.py, and I am passing fw,
armature (I’ll probably create a prefix for each armature), and ordinary
objects, not currently including EMPTY type objects.

I am not currently exporting humanoids, but bone animations will be
exported during the test.

I may export humanoids separately and hand integrate.

I’m guessing importing glTF animations will be an import option I’ll look
for, or one can test by selecting the animation tab and hitting the play
button in the dope sheet (it appears when you select Animation).

There are a few changes to export_x3d.py, and this is new code for
exporting as XML.

I may bring over humanoid export code from
BlenderX3DSuppport/io_scene_x3d/export_x3d.py I wrote some time ago.  That
would be easier than rewriting what I have.
