If that can be useful, at Office Towers we use the following, which are hand-waving and body gestures derived from the old Avatar Studio as it relates to avatars.













Objects also have similar attributes like 'door' [open, close] as you suggested, and others such as 'elevator' [up, down], or 'vehicle' [drive, reverse, turn, stop], etc. 


Let's not forget all the DIS' Protocol Data Units (PDU) highly specialized action types that could also be included:




The list could get very long and implementation has largely been left to developers. I'm not sure how to standardize it without standardizing the actual gesture/motion/action too. And that's without giving any consideration to mocaps. Do you have ideas how that could work?

Would "bending" (from The Avatar) or kinesis be a useful top-level semantic class for this?

In addition to the transform tag, there’s also a concept of transforming shapes or models. I have not seen any mention of applying semantics to shape yet. I suggest the following words leading to what I call “metamorphical semantics”:

1.     Bend

2.     Break

3.     Straighten

4.     Glue/Rivet/Bolt/Attach

5.     Drill

6.     Screw

7.     Saw/Cut

8.     Stab

9.     Spoon (verb)

10.  Pour

11.  Chew

12.  Bite

13.  Filter

14.  Mold

15.  Open

16.  Close

17.  Apply Function (my orbital use case, transforming a sphere into a rose in a shader).   Also, FX3D and FVRML.

18.  Pedal (verb)

19.  Steer (verb)

20.  Turn (verb)

21.  Gallop

22.  Canter

23.  Run

24.  Jump

25.  Walk

26.  Stroll

27.  Plow

28.  Collide

29.  Explode

30.  More?


I believe these is handled in X3D through interpolators and HAnimMotion tag.   There are several types of interpolators.


I found this:




As a side note:  Metamorphical fantasy is most interesting for me.
