[x3d-public] Blender > Exporting rig transforms to HAnim?

That's just not true. Both Blender and glTF (just like X3D) support
arbitrary keys (times) that map to values. They are both consistent in
this regard with X3D "interpolator" concept (list of keys that map to
a list of key values, and the only requirement is that list of keys is
ascending; there can be varying distances between each key).

So they don't have to be fixed steps. It would indeed be very bad if
they limited animations' keys to fixed time steps, but they don't,
they never did. I rely on these Blender and glTF features every day :)

They (Blender and glTF) also both supports linear or curves for any
interpolator.

Regards,
Michalis

I have seen hints in Rhino that at least it would seem to support exporting x3d as a hierarchy of Transforms for the skeleton and hints that author could get the list of vertex bindings and weights, and other Bongo stuffs; even the magic of tweening could be available with several interp math choices.
