Event Graph ROUTE Table 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.

Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (1)	LightDirection PositionInterpolator set_fraction SFFloat	then	LightDirection PositionInterpolator value_changed SFVec3f	→ ROUTE event to (2)	SunLight DirectionalLight set_direction SFVec3f
Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (1)	LightColor ColorInterpolator set_fraction SFFloat	then	LightColor ColorInterpolator value_changed SFColor	→ ROUTE event to (2)	SunLight DirectionalLight set_color SFColor
Clock TimeSensor fraction_changed SFFloat	→ ROUTE event to (1)	LightAmbient ScalarInterpolator set_fraction SFFloat	then	LightAmbient ScalarInterpolator value_changed SFFloat	→ ROUTE event to (2)	SunLight DirectionalLight set_ambientIntensity SFFloat
