[x3d-public] ProtoInstance problem in VRML97, ClassicVRML conversions fixed

[John Carlson]

I guess this means that name is not a required field in ProtoInstance?  Or
not?  Is this updated in X3DJSAIL yet?   Are we hunting down the name via
USE, requiring name, or creating a new tag in XML?  And a new class
inherited from ProtoInstance in Java?  Does the code generating X3DJSAIL
code need to find the name and populate it?  What if USE is used and name
is wiped out?

Thanks,

John

Any decision made that I can take action on?

Found and fixed a longstanding undetected error in the X3D to (Classic)
VRML conversion spreadsheet: prototype instances mistakenly had their name
repeated as a field.

original source .x3d excerpt:

        <ProtoInstance name='CircleFish'/>

mistakenly/inadvertently translated as:

 CircleFish {
    name "CircleFish "
}


now correctly translated as:

 CircleFish {
}

Please update any local archives you might have.

Trouble reports with VRML97/ClassicVRML test suite examples and conversions
are always welcome.  We don't have a validator for these, so issues are
welcome.

Have fun with VRML97 and ClassicVRML prototypes!  8)

all the best, Don
