InlineImport.x3d (X3dToXhtml listing)

Event Graph ROUTE Table entries with 2 ROUTE connections total, showing X3D event-model relationships for this scene.

Each row shows an event cascade that may occur during a single timestamp interval between frame renderings, as part of the X3D execution model.

description='Load model that provides external access to a node via an EXPORT statement, accessed by IMPORT statement in this model'
This node can send or receive ROUTE events via DEF='MyInlineModel' or via <IMPORT AS='MyInlineRootTransform'/>

line 37
IMPORT

<IMPORT inlineDEF='MyInlineModel' AS='MyInlineRootTransform'/> matches local node
<Inline DEF='MyInlineModel'/> which can send or receive events between different X3D models,
if this parent model has ROUTE statements to exchange events with the child Inline model.

Additional guidance on X3D animation can be found in the 10-Step Animation Design Process and Event Tracing hint sheets. Have fun with X3D! 😀

Applying this design pattern in concert with naming conventions and metadata vocabularies holds excellent potential for use in Smart City visualization.'/>
