[x3d-public] Convert to X3D (from glTF, OBJ, STL, Collada, ...) and change X3D encodings using online Castle Game Engine converter

[Michalis Kamburelis]

Note about terminology:

- You wrote "V2.0 VRML file (but .x3dv)" -- note that you should store
VRML 2.0 files with .wrl extension.

- You wrote "V3.0 Classic VRML file", I understand it as "X3D 3.0 file
in classic (VRML) encoding" :)

In general, repeating the same DEF is allowed in VRML and X3D. The
last DEF "wins" (obscuring previous DEF definition of the same name).
Although I would discourage this practice, but specification allows
it.

Please send me the input file so I can look into it. In case of VRML
2.0 -> X3D 3.0 conversion, the input and output should match very
closely. There must be a reason why converter repeated many DEFs.

Regards,
Michalis
