[x3d-public] Wishlist: X3DUOM visualization

[Joseph D Williams]

➢ Why are X3D experts satisfied with text?

Not satisfied, just a basic ideal and I think a requirement that there exists a human-readable version that is complete and has a structure that contains critical data for a high-performance interactive scenegraph allowing realtime internal and external transactions using multiple media and interface styles. 
This is why x3d uses a certain vocabulary and data structure that is extensible to include new functionality. 
To validate something, to identify that you can share, then most basic is that you can literally read the stuff and at least try to understand whether it is worth trying to use it in your content. Also, you really want a convenient way to create and share what you have another way than a picture of the tool gui to save what you have for the next project. So, at some level, for some level of validation, I would say yes, we need a text form for anything in x3d. That is just being courteous and thoughtful to the community. 
Thanks, 
Joe

I’m hoping for a better “XML” that’s actually feasible in a VR setup, Don.   I think computing is moving away from the desktop/paper-like approach.

That’s why I’m exploring 3D specification   based on Java and ISO standard specification language.  The first task is getting the X3D specifications into that language.  Next we figure out how to visualize the specification in X3D.  I’m aiming for explaining X3D concepts in 3D.

I don’t know if semantics or specification is better.   Perhaps the best of both worlds?

Even the guy behind the DynaBook said we’re stuck in this paper-like world we’ve created.

Hi John. Your mail identifies how the X3DUOM (an XML file matching X3D Architecture Specification) is implemented as Java classes.

Not clear what the goal of your visualization might be.  Sofar we've made all of this information readily available to programmers in XML, Java and Python.

I'd suggest that the X3D Architecture Specification itself is the authoritative "visualization" of What It All Means.

There is also the Interface Hierarchy, a plain-text (ASCII art) tree version of all interfaces and nodes, originally produced by Joe Williams and faithfully updated by editors as we've progressed.

* X3D4 Architecture, Clause 4 Concepts, 4.4.2.3 Interface hierarchy

Use the X3DUnifiedObjectModel40.java to instantiate the 4.0 version of X3DUOM, then "marshall" out (with the get methods) the 4.0 version of the X3DUOM to MVC view code (possibly using an X3D encoding) and display.
