I was playing a bit more and noticed a few things.
ROUTE has fields ?
help(x3d.ROUTE)
Help on class ROUTE in module x3d:
class ROUTE(_X3DStatement)
| ROUTE(fromField='', fromNode='', toField='', toNode='')
|
| ROUTE connects output fields of event-producing nodes to input
fields of event-consuming nodes.
|
| Method resolution order:
| ROUTE
| _X3DStatement
| builtins.object
|
| Methods defined here:
|
| __init__(self, fromField='', fromNode='', toField='', toNode='')
| Initialize self. See help(type(self)) for accurate signature.
|
| ----------------------------------------------------------------------
| Data and other attributes defined here:
|
| FIELD_DECLARATIONS = [('fromField', '', 'SFString', 'inputOutput'), ('...
Probably for convenience. It may make sense to introduce X3DStatement
'parameters' or 'properties' although probably not a priority.
help(x3d.Scene().children)
Help on list object:
class list(object)
| list(iterable=(), /)
'children' are just lists, eg. can contain anything rather than only
X3DChildNodes.
Perhaps introduce executioncontext to add routes to, ala SAI.
DEF is a field ?
Help on Shape in module x3d object:
class Shape(_X3DShapeNode)
| Shape(DEF='', bboxCenter=(0, 0, 0), bboxSize=(-1, -1, -1), USE='',
class_='', appearance=None, geometry=None, IS=None, metadata=None)
|
| X3D element
|
| Method resolution order:
| Shape
| _X3DShapeNode
| _X3DChildNode
| _X3DNode
| builtins.object
|
| Methods defined here:
|
| __init__(self, DEF='', bboxCenter=(0, 0, 0), bboxSize=(-1, -1,
-1), USE='', class_='', appearance=None, geometry=None, IS=None,
metadata=None)
| Initialize self. See help(type(self)) for accurate signature.
|
| ----------------------------------------------------------------------

|
Probably for convenience. May lead to allowing routing to a DEF property.
Could be an extra name property/attribute.
String fields can contain anything:
x3d.Shape(DEF=x3d.Scene()).DEF
