[x3d-public] glTF 2.0 schema

[Brutzman, Donald (Don) (CIV)]

Thanks for notice about glTF schema.

 

We won't be connecting that in any way to X3D XML Schema or X3DUOM.  Apples
and oranges: X3D Schema validates X3D models, glTF Schema is intended for
glTF models.

 

X3D4 authors have two options for use of glTF2:

*	Direct inline
*	Full conversion to corresponding native X3D

 

Have fun with X3D!  8)

 

all the best, Don

Hi John, 

The thing to do is to somehow hook up the gltf schema with the xml schema so
that when a scene to be validated encounters imports it can just read the
thing and proceed with the validation. I don't see how to perform complete
validation without examining imports. Or, is it OK to just say the file to
be imported has been validated independently and so the file being validated
is ok? 

 

Just amazing where this gltf json has become with so much progress in
standards-track definition of the various objects and documentation. 

Sorry to not study more on this but me, from the gltf json structure and
schema, still thinking how to assemble the various gltf files to compose a
real node like the hanim Displacer. Still looks like to me that their use is
to import some known set of json objects to replace various fields in
various x3d concrete nodes. For instance, an animation channel with known
behavior so that the author only needs to define the files for the fields
and supply target Route(s) from-to the target fields. This is perfect for
building a general purpose animation prototype when we use a standard
humanoid where behaviors can be developed then reused from a library. 

Thanks, 

Joe

Based on schema 2020-12:

Sorry for any confusion.   I should have done research before blabbing.
