<br>
In the case of X3D, it is the database. Yes, the X3D scenegraph is the <br>
database. And, Yes, it is alive!<br>
<br>
Why consider any other database style than X3D XML encoding? It can <br>
produce a validatable n-D authortime and runtime database that can <br>
leave realtime tracks in any dimension and be used to interactivly <br>
vizualize the present(s) and simulate futures. If some part of your <br>
feature names and data needed to store or produce your effects is <br>
missing, then there is plently of room to create your own meta <br>
ontology and data and events -- even interact with them. Then, you can <br>
script it while it is running to keep it up to date or whatever, and <br>
produce a serialization at any moment.<br>
<br>
So, to interact with the data at authortime all you need is XML/DOM <br>
tools that like X3D XML Schema.<br>
To fully vizualize and animate it, you need a time- and event-driven <br>
player that likes X3D events.<br>
<br>
All Best,<br>

OK thanks again John, I got all that, I'll save it for when I do a <br>

Roy is shining a light on some tricky issues.<br>
<br>
These nodes are an area of X3D specification refinement that has suffered from a lack of example scenes.<br>
<br>
Does anyone have (or know of) X3D scenes that demonstrate intended operation of nodes in the Layer and Layout components?<br>
