[x3d-public] This looks like a great DIS example!

This looks like a great EspduTransform example:

I plan to modify this example to use on my equation visualization
whiteboard.

Question:  would it be difficult to port X3D-DIS to a socket.io JSON-based
protocol?  I’ve heard that you were suggesting converting DIS to XML.
Obviously such things require a lot more validation than DIS itself.  I
would probably just use JSON arrays.  Socket.io would give me the option of
multiple transports built in, including http fallback, websockets and
webtransport and support for several languages.

As for DIS implementations with X3D, I’ve heard of Xj3D, FreeWRL and X3DOM,
but my implementation environment is currently X_ITE.  Can we separate DIS
from these so I use DIS in X_ITE?  I know DIS is not supported in X_ITE
and, AFAIK, X_ITE is against the use of DIS.  I’m frankly afraid of
breaking my X_ITE license.

I couldn’t get my shader uniform modifying sliders working in FreeWRL yet.
They work great in X_ITE.

Perhaps a simpler implementation with a PROTO for my six multiuser sliders
would be better?  I don’t like the idea of sharing DEF names across the
network.  DIS looks like a big hammer, except entities would be nice as
well, plus possible animation of avatars.

Are there any HAnim DIS animation examples, beyond what’s possible in
FreeWRL (needs work, and I’m too lazy to download required .dlls).

Thanks,

John
