[x3d-public] Archive does not validate with X3D validator, at least with schematron.

➢ Perhaps it would be best to start with python or java to create humanoids, instead of starting with XML?

To me, the opportunity to use alternate encodings is fun but really, XML is hard enough and I have not seen any additional expressive concepts to aid authoring in other encodings, only limitations because mostly not intended or well developed for the compete scene graph, but potentially very useful for certain transport jobs. 
For the XML, we are accumulating authoring aids and firm validation by reliable schema tools that may be enough to capture the full expression of x3d. Thus, when we want to transport x3d scene graph, we can now best trust the x3d xml schema. So, XML becomes the standard definition by which conformance by all others are therefore derived. 
Use whatever you wish, just please, for validation, present best xml useful for example user code in Part 1 Annex A. Please  make sure you can generate reasonable .x3d XML with appropriate comments from whatever you use to generate the V2 LOA4 in appropriate Human dimensions mostly shown in the last two tables in annex A. If we can refine those numbers then we can change the value in the table. We just need an up to date xml example in Part 1 Annex A. 

➢ What I suggest we try to do is create a "DNA" builder, by reverse engineering humanoid examples.  And from the "DNA", procedurally generate humanoids.

Note that the schema for the HAnimHumanoid fully describes the joint hierarchy and the various sites associated with each Joint. A plan is that we should be able to build a character based on that data directly, if we know all the measurements. A smart enogh ai would naturally know to start with the suggested set of joint and site locations in human scale appropriate for the model dimensions. 

Thanks, 
Joe

I realize hand-crafting any computer code, in any language is tremendously hard.  That's why I try to do automated generation (program synthesis) as much as possible.

That's why I attempted to create grammars, schemas, etc., because they lead toward "procedural generation." This is a bit like generating a humanoid from a kind of "DNA" or metahuman. What I suggest we try to do is create a "DNA" builder, by reverse engineering humanoid examples.  And from the "DNA", procedurally generate humanoids.

Perhaps it would be best to start with python or java to create humanoids, instead of starting with XML?

Just thinking out loud here. Not demanding anything at this point.

I think the challenge is to create a prototype, then tweak the prototype.  Let me know how I can help, possibly by converting the prototype to various encodings and bindings?

Maybe it would be appropriate to develop something that would mutate a model?

Thanks for listening.

John: HAnim models are among the largest and most detailed we have.  It is a lot of work to get a 3D model perfectly correct… but then it works and is checkable/repeatable/useful.  I don’t think that anyone anywhere can do any kind of apparel or medical modeling with paying immense attention to Quality Assurance (QA), as we are.  The day after a flashy demo is important too.
 
Over time, by paying attention to bugfixes and corrections through the addition of validation and diagnostics, Joe and I have reduced the number of previously undetected bugs from gargantuan to merely huge.  Half of that challenge is getting diagnostics correct in the first place, no easy feat.  The Great Bug Hunt continues, to good effect.
 
If you want to see our latest test outputs from X3D Schematron, this past weekend I have updated that file as follows.  It is prominently listed in the HAnim Example Archives themselves.
 
• HumanoidAnimation (HAnim) X3D Examples Archive
• 8 Directories, 86 X3D Models (with most models working but few perfect)
• https://www.web3d.org/x3d/content/examples/HumanoidAnimation
 
• https://www.web3d.org/x3d/content/examples/HumanoidAnimation/build.schematron.log.txt
 
Also updated, here is an improved feature in the pretty-print HTML for each model, which includes much special handling of HAnim.  This continues the automated elaboration of Joe’s original technique using plain-old-ASCII text descriptions of the HAnim tree structure.  Enjoy.

So there's probably something specific to X3D schematron (not XML). I will try my version.
 
Suggestion. People find a reasonably patterned HAnim V2 model, and I will copy the pattern to create an LOA4 model.  I believe this is the best path forward.
