I would like to announce that X_ITE now also has support for .glTF, .glb, .obj, .stl, and .svg. 😀

As well as importing files, X_ITE can output XML, VRML and also JSON now by implementing toXMLString, toJSONString and toVRMLString.

Thanks John, your suggestions pretty closely match mine. Workflow seems external to X3D4 pathways, typically performed offline. It seems sensible to avoid intermediate-format conversions if possible, since that offers more potential for “lost in translation” conversion problems.
Please note that X3D4 specification only supports glTF loading and rendering, not .obj files. Specification excerpts follow:
* X3D4 Architecture, Networking component, 9.4.2 Inline
* https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/components/networking.html#Inline
* The run-time system can support any number of 3D model resource types as long as those follow the abstract model definition (see 2.[RFC2077]), provide a registered content type ( e.g., model/x3d-xml, model/gltf-bin, model/stl, etc.), and can be determined with some form of content negotiation (see 2.[RFC2616]). The run-time system must support at least one X3D type ( e.g., model/x3d-xml) but can also support and negotiate any number of X3D encodings and (optionally) non-X3D representation formats. Support for loading glTF assets (see 2.[GLTF]) also requires support for Shape component level 2 and Lighting component level 4.
* X3D4 Architecture, Networking component, Table 9.3 — Networking component support levels
* https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/components/networking.html#t-supportLevels
* Level 4, prerequisites Core 1 and Grouping 1, Nodes/Features and Support:
Model support
Support for glTF models in Inline nodes, in .gltf (model/gltf+json) and .glb (model/gltf-binary) formats.
Requires support for Shape component level 2 and Lighting component level 3.
Minimum required glTF support:
* transformation hierarchy,
* meshes,
* physical materials,
* loading of external binary data referenced from .gltf files ( e.g., for vertex coordinates).
* X3D4 Architecture, Clause 2 Normative references
* https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/references.html#GLTF

Careful scrutiny of the prose above should reveal that we do not forbid browser support for other formats. A premier example browser which not only loads and displays numerous formats but typically can also save back out as X3D or VRML:
* Castle Game Engine, view3dscene 4.2.0
* view3dscene is a viewer for many 3D model formats: glTF, X3D, VRML, Collada, 3DS, MD3, Wavefront OBJ, STL and (2D) Spine JSON and sprite sheets (in CGE, Cocos2d, Starling XML formats).
* 4.2. Converting to X3D

My tendency would be to go from X3D to glTF or COLLADA to glTF and then load glTF into three.js. Also x3d to OBJ looks like a thing with aopt.
I believe both OBJ and glTF are supported by X3d4.
OBJ is native to three.js
If you find a tessellation library in all of this, that would good to know.

Apparent overlap: capability for loading glTF models.
Just curious, thanks for all opinions. If there is something worth including on X3D Resources, will add it.
all the best, Don
