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.

TextSender
ProtoInstance textInput SFString |
OurNetworkChannel
ProtoInstance Connection |
No ROUTE connection found for output events from this node. This ProtoInstance contains SFNode/MFNode fieldValue declarations with direct access to other nodes, and thus has potential to produce run-time animation. |
