[x3d-public] Experimental support for InlineGeometry in X_ITE

[Don Brutzman]

Holger, thanks for sharing an excellent example.  Glad it works!

For your example, it certainly is convenient to load the first geometry
node in an X3D model... but I am wondering if it might be better to
encourage Inline with a regular EXPORT/IMPORT combination... I guess
InlineGeometry load of first Shape saves loading a full X3D Inline, and
possibly needing to hide it under a Switch (or use visible='false') to
avoid rendering.

Building on your example, perhaps we might extend the syntax of
InlineGeometry url to point to an EXPORTed node, i.e. change your

   - <InlineGeometry DEF='InlinePoints'
                   url='"assets/Points.x3d"'/>

to something like

   - <InlineGeometry DEF='InlinePoints'
                   url='"assets/Points.x3d#ExportedPointSet"'/>

Such a url extension is similar to how we handle external prototypes, and
gives more flexibility regarding what to extract from the remote scene.
Also less error-prone in the future if someone shuffles the geometry around
in an external .x3d file.  Nevertheless, it might also leave more
opportunity for error if the EXPORT node is not geometry.  Hmmm... seems
like we need to be careful here.  Wondering what people think.

I have added another example that shows Sunrize successfully loading an STL
file via InlineGeometry.

   - X3D Example Archives: X3D4AM, X3D for Advanced Modeling, Additive
   Manufacturing, Cleat Clamp Inline Geometry
   - CleatClamp STL loaded by InlineGeometry with Appearance applied.

Additional progress:  I have added InlineGeometry to v4.1 drafts for X3D
Tooltips, XML DTD and Schema, X3DUOM, X3DJSAIL Java, X3DPSAIL Python, and
X3D Ontology for Semantic Web.  Node-aware links for each of these (and to
X3D spec) are found at the top of each tooltip.

Again thanks for super demonstration of progress, and contributing to our
thinking through InlineGeometry possibilities fully.

all the best, Don
