[x3d-public] Minimum legal root node

[Joseph D Williams]

➢ "I think we just wiped something out. "+selectorField+" is unavailable."

The dreaded I think we just …  message. 
To document paths, think of the x3d internal behavior graph which comes free and the only thing you may need to keep track of yourself is directOut(s). Just mind your fanins and fanouts, use timestamps to control loops, and don’t interrupt the cascade. How to make the a picture? 
Thanks, 
Joe

At one point I had suggested SFPath and MFPath as a way to traverse a hierarchy.   That is, they pointed at lists of string | number.

Would doing something like this be useful?   I may have a partial (at least for my purposes) solution here:

Right, we need a good way to get data for an x3d node’s field by specifying the .json file name and  whatever hierarchy of names gets to the desired data field.

My guess is #name is used as a selector to pull a specific node inside the JSON.

showing example use of gltf in x3d, is this a case where it is not quite right to have a shape as a root node? Except that is, if the root node is a Shape using gltf? The gltf ‘node’ contains the stuff for a shape and its transform in its parent space. It is the lack of a parent grouping node that makes the use of Shape as a root node a problem, but the gltf node holds both. 
Thanks, 
Joe
