With the VisibilitySensor bounding box (represented by a white IndexedLineSet box) visible to the viewer, an enterTime field is generated and sent to a TimeSensor node to begin a color interpolation of the Sphere geometry. Moving to the second Viewpoint behind the VisibilitySensor bounding box sends the exitTime event to the TimeSensor to stop the color interpolation.'/>

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.

VIS_SENSOR VisibilitySensor enterTime SFTime	→ ROUTE event to (1)	TIME TimeSensor startTime SFTime	then	TIME TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP_COLOR ColorInterpolator set_fraction SFFloat	then	INTERP_COLOR ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	COLOR Material diffuseColor SFColor
VIS_SENSOR VisibilitySensor exitTime SFTime	→ ROUTE event to (1)	TIME TimeSensor stopTime SFTime	then	TIME TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP_COLOR ColorInterpolator set_fraction SFFloat	then	INTERP_COLOR ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	COLOR Material diffuseColor SFColor
