[X3D-Ecosystem] OSC mocap support in X3D Browsers

[John Carlson]

Yes, my understanding is that some OSC servers can be programmed, but I
wasn’t sure if it was at runtime.

Whatever OSC server he comes up with is okay, I just want to be able to use
it from my webcam and chosen x3d renderer.

OSC looks huge, and I feel he will be programming a miniscule piece of it.

I don’t think that tying development to one device or solution is
necessarily a good thing.

If he wants to look at my implementation and add my protocols beyond OSC et
al, cool.  I feel I also have a somewhat flexible way of approaching things:

https://github.com/coderextreme/deafblind/blob/main/multi.py

(Search for my 3 protocols, Cppon, Impact and Mocap). There are other files
for multiple avatars at the same time.  The three 3 protocols have common
header for LIRCom services, my multi-app protocol, and some files use
socket.io to send data to X_ITE.

I’m thinking UGE is Unreal.  I’m not seeing that advancing networking in
UGE advances open standards.  Which is probably Don’s comment as well.

If he can document what he does for mocap, then others can pick up where
he’s left off, and port the solution (unless he wants to do it).

I’m not particularly looking to do this myself, I’m hoping for common
solutions which can be duplicated and collaborated on.

Ultimately, to really work on a secure multi-app, multi-device, multi-user
message bus, you’ll find a lot more is needed beyond OSC that I’ve seen,
but I encourage people to show me I am wrong.  Part of the stuff I consider
are bearer tokens (mostly implemented, except for deprecation and creation)
and jwt (just being considered).  My first attempt was LIRCom, then
socket.io and now I’m looking at security.

I’m not stating I’m the world’s expert on networking.  I encourage looking
at stuff like OAuth/OAuth2 and beyond.

If we’re really going to get to a Metaverse, all this needs to be
considered.

For example, Google: “security in open sound control” and no, I don’t want
to bring anybody’s VPN into my LAN.
