[x3d-public] Joe, which model?

[John Carlson]

For clarification, should I download the LOA4 VRML example in HAnim pt1
Annex A?  I’m wondering how to read VRML into X3DJSAIL or x3d.py? I know I
can convert to XML using Michalis’ tool.  Does X3DJSAIL support
createX3DFromString?

It would be convenient to provide me with a link

Thanks!

Note on the below…I scraped the DEFs from the model, I didn’t discover them.
