[x3d-public] Ran across an interesting example.

Fri May 19 02:57:01 PDT 2017

Below X3D XML NOT viewable  in X3DOM, (Octaga??), Instant Player (console goes into infinite loop),  H3D complains about: (Unnamed Normal.vector.  Field has size 6).  I think it may be because normalIndex has -1’s when normalPerVertex=false???  If I take out the -1’s, it’s viewable in X3DOM, Octaga, InstantPlayer, and H3D.  The content still needs work, of course (It’s supposed to be a cube!).

X3DOM’s console looks like:
x3dom-full.js:4743 Uncaught TypeError: Cannot read property 'x' of undefined
    at x3dom.registerNodeType.defineClass.nodeChanged.nodeChanged (x3dom-full.js:4743)
    at x3dom.NodeNameSpace.setupTree (x3dom-full.js:2869)
    at x3dom-full.js:2869
    at Function.Array.forEach (x3dom-full.js:2)
    at x3dom.NodeNameSpace.setupTree (x3dom-full.js:2869)
    at x3dom-full.js:2869
    at Function.Array.forEach (x3dom-full.js:2)
    at x3dom.NodeNameSpace.setupTree (x3dom-full.js:2869)
    at x3dom-full.js:2869
    at Function.Array.forEach (x3dom-full.js:2)

What does quality assurance report?  I don’t get any significant warnings from X3D-Edit or X3DJSAIL, that I can tell!

Not sure about the standard, but leaving out the -1’s makes sense if normalPerVertex = false, I think.  I’ll let others weigh in about the standard.

Thanks,

John
