this example. To my knowledge, unfortunately no public version this tool has been shared, but we did see some compelling demonstrations together at the Web3D 2025 Conference in Siena. I've copied Dr. Myeong Won Lee is you would like to pursue that further.</div><div><br></div><div>HAnimMotion is based directly on BVH files for motion-capture data. BVH has been widely implemented but inconsistently utilized... No particular standard can be found, and it seems to have been popular partly because the company BioVision was no longer in existence and thus unable to assert IPR or sue anyone.</div><div><ul><li>Wikipedia:
Biovision Hierarchy</li><li><a href="https://en.wikipedia.org/wiki/Biovision_Hierarchy">https://en.wikipedia.org/wiki/Biovision_Hierarchy</a></li></ul></div><div>Usually we are pretty insistent and onerous about insisting on 2 implementations before advancing any node in the standards. There may have been another implementation besides the Suwon codebase, am simply not sure. Given that it is very closely aligned with BVH, and we had multiple tools with a validating non-trivial example, I think we might have (reluctantly) moved forward with only one player... again, not sure. Sorry to be uncertain. Hopefully we did not blunder.</div><div><br></div><div>I don't blame you for questioning whether to go forward if no implementations exist... that is the primary bargain we make with the X3D and HAnim standards. Nevertheless I have high confidence that HAnimMotion node is well specified, HAnimMotion data is validatable, and HAnimMotion can be consistently repeatable by other X3D players.</div><div><br></div><div>I welcome any corrections and improvements to the Example Archives model.</div><div><br></div><div>Thank you for pursuing this. There are many thousands of BVH models out there (with some format variations and looseness involved). It will be great when we become adept at massaging & converting them into well-defined HAnimMotion nodes (X3D-Edit has an initial implementation). If we become really capable at that task, especially if using your planned implementation, we might then work on BVH validation reports during conversion as diagnostics, and perhaps even direct import (as a HAnimMotion node url field) as part of the draft HAnim v2.1 specification.</div><div><br></div><div>Seems like much excellent capability beckons!
