Event Graph ROUTE Table entries with 5 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.

SOCKET_TOUCHSENSOR TouchSensor isOver SFBool	→ ROUTE event to (1)	LIGHT_TIMESENSOR TimeSensor enabled SFBool	then	LIGHT_TIMESENSOR TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	WHITE_COLORINTERPOLATOR ColorInterpolator set_fraction SFFloat	then	WHITE_COLORINTERPOLATOR ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	BULB_MATERIAL Material set_diffuseColor SFColor
							then	WHITE_COLORINTERPOLATOR ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	BULB_MATERIAL Material set_emissiveColor SFColor
							then	WHITE_COLORINTERPOLATOR ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	LIGHTSOURCE PointLight set_color SFColor
