Two TimeSensors with cycleIntervals of 2 and 4 seconds animate a blue and green Sphere geometry respectively along the same distance. Because the cycleInterval of one TimeSensor is half that of the other, the fraction_changed events are routed to one PositionInterpolator twice as fast as the other TimeSensor, and the blue Sphere completes its animation twice as fast as the green Sphere. To verify this, click on the red Sphere to start the animation.'/>

Event Graph ROUTE Table entries with 6 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.

TOUCH TouchSensor touchTime SFTime	→ ROUTE event to (1)	TIME1 TimeSensor startTime SFTime	then	TIME1 TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP2 PositionInterpolator set_fraction SFFloat	then	INTERP2 PositionInterpolator value_changed SFVec3f	→ ROUTE event to (3)	second_ball Transform translation SFVec3f
TOUCH TouchSensor touchTime SFTime	→ ROUTE event to (1)	TIME2 TimeSensor startTime SFTime	then	TIME2 TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP3 PositionInterpolator set_fraction SFFloat	then	INTERP3 PositionInterpolator value_changed SFVec3f	→ ROUTE event to (3)	third_ball Transform translation SFVec3f

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