[x3d-public] IFS example to fix.

Please note that IndexFaceSet colorPerVertex field has default value TRUE.
* https://www.web3d.org/x3d/tooltips/X3dTooltips.html#IndexedFaceSet.colorPerVertex
* https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/components/geometry3D.html#IndexedFaceSet
So the warning was misdirecting… but there is indeed a problem. You have six vertices but two colors, and so will need to set colorPerVertex =’false’ to get what you intended (presumably a color on each polygonal face).
Scaling up by a hundred then reveals your mystery triangle.
all the best, Don

Subject: RE: [x3d-public] IFS example to fix.
When launched in view3dscene am getting the following errors (copied/pasted)
2 warnings:
X3D: Invalid number of items in a normal or texture coordinate array for shape "HAnimSiteShape:IndexedFaceSet(DiamondIFS)": Invalid index: 2, but we have 2 items
X3D: Invalid number of items in a normal or texture coordinate array for shape "HAnimSiteShape:IndexedFaceSet(DiamondIFS)": Invalid index: 2, but we have 2 items
Scene URL: "C:\Users\brutzman.IT160907-UWALPP\Desktop\IFS.x3d".
Use "File->View Warnings" menu to view these warnings again.
Of note is that there is no HAnimSite node, rather just Shape DEF=’HAnimSiteShape’
Likely cause: view3dscene is referring to a normal or texture coordinate array, but there are none provided, which is legal. Thus these warnings seem to be “false positives” by view3dscene. Suggest posting an issue there with this test scene; I’ve copied Michalis.
John: I used X3D-Edit to launch and render your model in multiple X3D browsers, but nothing visible (scene looks like a 10mm cube from 10m away). To improve this test, you might add a viewpoint or scale up the geometry to make successful results obvious.
* <Transform scale='100 100 100'>
Presumably you got a gazillion errors in the humanoid version because there were a corresponding gazillion USE=’HAnimSiteShape’ nodes in the original humanoid model.

Here is a small example that shows the potential issue, attached.
view3dscene reports errors, Schematron does not. I will attempt JSON next.

The way I'm reading above, the IFS has 6 coordinates and 2 colors. There should be more colors, correct? view3dscene detected this. I'll look up the IFS spec.
Thanks!
John
