[x3d-public] IndexedFaceSet collection

It might.  We’re thinking of creating new indexedtrianglesets in an adversarial network pair.   One network will create the ITS, the other one will validate it.  We’re not quite sure what will come out, and if this will be applicable to the rest of X3D.   That is, instead of using DTD, Schema, Schematron, Validator, etc, we just use a neural network which explains the errors.  This is the field of eXplainable Artificial Intelligence (XAI) http://www.darpa.mil/program/explainable-artificial-intelligence .  We’ll feed the validation results from schema and X3DJSAIL into the networks so they can learn how to explain things.

So far, just a thought experiment.  At least we are thinking about it.  And it takes real intelligence to bootstrap the artificial stuff, so that’s good.

Does anyone care what X3D encoding we use?

If anyone knows related work in either the schema area or the text area (i.e.: program validation) let me know. I’m seeing some now for schemas.  Off to read.

I have a large number of converted CAD files which usually have a large number of IndexedTriangleSet nodes, some of those nodes contain 'large' numbers of vertices ; I consider 60k a large number of vertices, you may judge differently. For an example, see http://www.kshell.com/pages/x3dom_gltf_demo/mixing_tank.xhtml 

Would files of this type suit your purpose?

N.B. They are specifically IndexedTriangleSet nodes, not  IndexedFaceSet
