[x3d-public] Proto expander. Scripts in protobodies without a DEF

Thu Jul 14 17:57:33 PDT 2016

I don’t know if the script is broken or something else.  The expanded version doesn’t work in any browser I tried.  The proto version works in at least octaga.  The original Proto version does not work in X3D JSON Loader (Cobweb).  The original Proto version does work in normal Cobweb.

X3D JSON -> XML version without Proto Expander is here (broken in Cobweb):
