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.

Toucher TouchSensor isActive SFBool	→ ROUTE event to (1)	Clock TimeSensor enabled SFBool	then	Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	InterpolateCrossSection CoordinateInterpolator2D set_fraction SFFloat	then	InterpolateCrossSection CoordinateInterpolator2D value_changed MFVec2f	→ ROUTE event to (3)	AnimatedCrossSectionExtrusion Extrusion set_crossSection MFVec2f
Toucher TouchSensor touchTime SFTime	→ ROUTE event to (1)	Clock TimeSensor startTime SFTime	then	Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	InterpolateCrossSection CoordinateInterpolator2D set_fraction SFFloat	then	InterpolateCrossSection CoordinateInterpolator2D value_changed MFVec2f	→ ROUTE event to (3)	AnimatedCrossSectionExtrusion Extrusion set_crossSection MFVec2f

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