Rich,
I imagine (I don't know) that if VRML loaders support PROTOs they do it by
expanding out a complete copy of the PROTO into the scene graph every time
it is called (with the appropriate 'IS' values substituted).
I am attempting to build an 'editor' as opposed to a loader. by this I mean
that it keeps the PROTO in its original form, so that is can be edited and
then saved with the PROTOs intact. see ( http://www.martinb.com/ )
The current version of the program (version 3.34) should now be able to load
PROTOs correctly and export them as Java programs. However it does not
display PROTOs correctly yet in the following respects: IS values are not
yet correctly substituted, also ROUTEs inside PROTOs are not correctly
handled, also when exporting to C then Java type parameters are used in the
call instead of C format. I am planning to fix these 3 remaining issues in
the next release.
Would this be any use to you when these things are fixed? I know you tried
the program some time ago and it was very buggy, I'm gradually improving the
quality, but there are still lots of bugs, and I would appreciate any
reports. I am planning that the program should be able to handle all VRML
files (such as the excellent files that were on your web site
like:life,thought, time, etc.)
I would also be interested to hear how others are handling PROTOs in their
programs.
