Event Graph ROUTE Table entries with 10 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.

This node has 10 outgoing ROUTEs, which is greater than $maxROUTEdepth=8

ProtoInstance
TSSRPair
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.

ProtoInstance
BeamCylinder
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.

ProtoInstance
BeamCylinder
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. 

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