[X3D-Ecosystem] X3DJSONLD 12 plans for beta, was: Re: [x3dom-users] Donation of STL and PLY output

[John Carlson]

Development plans for X3DJSONLD 12 beta (web viewer multi-format bake-off)
status.

* Three spine points in x-axis extrusions worked great for X3DOM. Yay!
Thanks Andreas, for your hints on GitHub.  Solved a very long term issue I
was having!

*  I have been working on Proto Expanders for STL and PLY output.  AFAIK,
these formats don’t offer a native way to create prototypes.  So hopefully,
I will be able to combine the proto expanders (via JSON) at some point in
the future, and we will have a 4th implementation of proto expansion
(X_ITE, X3DOM, my deleted version and the new version) on the web.

* I am going to start working converting the AllenDutton.x3d to JSON (done,
by X3dToJson.xslt, and create3000 thanks, Don and Holger!) and then to PLY,
to hopefully to gain some color examples of humanoids in PLY.  Jin Scaled
V2 Is an option to convert.  Will also consider converting a SuperCobra
example to PLY.  PLY output is a feature included in X3DJSONLD 12.
Previously, I only considered PLY input. A “friend” helped with
tessellation.

* I plan to convert my example.ply to a rubikPly.x3d example, to enable
gradient shapes with prototypes.

* Extrusion conversion to STL needs further testing, and I don’t recall if
I fixed PLY output yet.  pp3.x3d to STL is  working, but not deployed yet.

* I still plan on putting X3D binding outputs in a tabbed panel.
Currently, I use table cells.  More debugging on outputs will be useful.

* Waiting for demo on how to load any scene into Castle mobile model
viewer, will add a third iframe.

* Maybe I’ll start converting from X3D JSON to .gltf.

* Starting to think about how to do Inline and ExternProtoDeclare
conversions to STL and PLY.

* Will start to consider STL and PLY Serializers in the X3DJSONLD test
harness.

* At some point, I’ll reconsider asking my “friend” to improve the Script
to script conversion for X3DOM, likely based on:
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/Script.js

* Converting metadata to PLY comments, especially author and license
information.

If anyone wants to experiment with JSON Proto expansion to STL, this is
available:

https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/html/main_viewer.html


I don’t currently have it deployed to production.  And older alpha version
is available.
