Event Graph ROUTE Table entries with 3 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.

Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (1)	Movement Script set_time SFFloat	then	Movement Script position_changed SFVec3f	→ ROUTE event to (2)	SpherePosition Transform translation SFVec3f
			then	Movement Script text_changed MFString	→ ROUTE event to (2)	myMessage Text string MFString

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