Event Graph ROUTE Table entries 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.

TouchStart TouchSensor touchTime SFTime	→ ROUTE event to (1)	Movie MovieTexture set_startTime SFTime
TouchStart TouchSensor touchTime SFTime	→ ROUTE event to (1)	GoTimer TimeSensor set_startTime SFTime	then	GoTimer TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	GoFlash ColorInterpolator set_fraction SFFloat	then	GoFlash ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	GoMaterial Material set_diffuseColor SFColor

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