You can find example BVH-to-X3D conversion results at
* X3D Example Archives: Humanoid Animation, Motion Animation
* Motion Capture (MOCAP) examples using Humanoid Animation (HAnim)
models illustrates conversion from BioVision Hierarchy (BVH) files for
Character animation (such as 1.bvh).

/1.bvh
*
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/MotionAnimation
/1.bvh.txt
Additional good examples welcome, we can add them to the HAnim Examples
archive. Got one?
I just checked the BVH converter in rejuvenated X3D-Edit and it seems to
still work fine. 8)

Adapting the X3D-Edit converter source to be part of our X3DJSONLD X3DJSAIL
X3DPSAIL libraries seems like an interesting utility function to add
someday.

Have fun with X3D and BVH! 8)

Hi John. Good ideas, thanks for sharing them.
Once again, it appears as if all the capabilities necessary to accomplish
that are defined in X3D4 with immense sets of BVH captures available out
there. Good hunting, sir.

Hmm. I suggest extending the BVH to include multifigure collaborative
motions like dancing (think Virginia Reel) and sports. That is, some kind
of composed BVH with multiple avatars.
This may already be done.
Thanks!

Here is a "new" proposed strategy, trying to say crisply the many essential
ideas that are well known already by active participants in the X3D
community.
(draft) Avatar Strategy: Open, Interoperable, Personal, Secure
No standardized definition for "avatars" is provided in X3D4, but.
* Many alternatives are possible, the "X" in "X3D" is Extensible.
Vive la difference!
* X3D includes multiple levels of detail (LOD) if progressive avatar
fidelity desired, this is essential for hugely scalable worlds.
* Most powerful Web3D example design to date: Silhouette Avatars by
IVN, https://ivn.net

* Metadata for identity, secure digital signature and even encryption
is possible.
* Composing 3D scans and motion-capture (mocap) data for full avatar
realism remains really interesting! Interesting progress continues on this
challenge.
X3D Working Group intends to demonstrate whatever avatar definitions are
agreed upon by Metaverse Standards Forum. We expect to show full matching
Implementation and Evaluation using X3D, learning further what avatar
designs work well.
Let's discuss please. All inputs and discussion welcome.
