glTF is a container file. It just lays out the structure of the
contents. The geometry, animation (including skinning animation),
and textures are all stored separately as binary files (with the
exception that the binary files can be stored inside the glTF as
URIs using the 'data' protocol - see RFC2397). Only the structure
is JSON. Also the structure part of glTF is not streamable nor
currently (as of V2.0) supports geometric compression.<br>

<p class="MsoNormal">Yes, I saw that. That’s what developed my
interest. I will be travelling to California for a wedding
June 13<sup>th</sup>-17<sup>th</sup>, and didn’t want to plan
another trip so close to that.</p>

<p class="MsoNormal">Reactive Vega also has a JSON format for 2D
visualization, and I think Kibana uses JSON as well, at least
for data, and for storing dashboards in Elastic. I’m wondering
if we should try to standardize. I do not think that glTF is
a particularly good format for visualization (something
SVG-like would be better), but I could be wrong, depending on
what’s developed on top of it. Perhaps writing extensions or
SVG-JSON would be appropriate? glTF is fine for low-level 3D
stuff. So what do we do, write a high-level serverside
streaming visualization library which outputs glTF? What if
the input to the library was X3D JSON, vtk.js JSON, Reactive
Vega, SVG-JSON or ??? Can X3DJSAIL output glTF?</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Should we start writing toStringGLTF() in
X3DJSAIL? Don? Should we write the conversion in XSLT or
JavaScript or Java?</p>
