1. HAnimMotion should have a skeletalConfiguration field similar to
HAnimHumanoid to facilitate interoperability.

SFString [in out] skeletalConfiguration "BASIC"

* HAnim2 vol. 1, 4.8 Modelling of humanoids
*

epts.html#ModellingOfHumanoids>
https://www.web3d.org/documents/specifications/19774/V2.0/Architecture/conce
pts.html#ModellingOfHumanoids

* X3D Architecture, 26.3.2 HAnimHumanoid
*
<https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01
/components/hanim.html#HAnimHumanoid>

components/hanim.html#HAnimHumanoid

2. Need a field describing number of rows in a motion value array, otherwise
(if no channelsEnabled array is provided) there is no unambiguous way to
determine the correct value. Suggested:

SFInt32 [in out] totalNumberFrames [0, +infinity)

* HAnim2 vol. 2, 6.3 Data structure of Motion object
*
<https://www.web3d.org/documents/specifications/19774/V2.0/MotionDataAnimati
on/MotionNodes.html#MotionObject>
https://www.web3d.org/documents/specifications/19774/V2.0/MotionDataAnimatio
n/MotionNodes.html#MotionObject

* X3D Architecture, 26.3.4 HAnimMotion
*
<https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01
/components/hanim.html#HAnimMotion>
https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/
components/hanim.html#HAnimMotion

3. If accepted, each of these needs a corresponding Mantis comment for
future revision of HAnim2.

 

all the best, Don
