Event Graph ROUTE Table with 4 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)	OnOffSequencer BooleanSequencer set_fraction SFFloat	then	OnOffSequencer BooleanSequencer value_changed SFBool	→ ROUTE event to (2)	RedSpotLight SpotLight on SFBool
Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (1)	ChildSequencer IntegerSequencer set_fraction SFFloat	then	ChildSequencer IntegerSequencer value_changed SFInt32	→ ROUTE event to (2)	ShapeSwitcher Switch whichChoice SFInt32

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