16	<meta name='description' content='A ProximitySensor with all default values is associated with a red Sphere geometry. The ProximitySensor, if activated (when the viewers avatar enters the bounding box of the ProximitySensor), should route events to a TimeSensor node and start an animation that would change the color of the Sphere from red to blue. Because the default bounding box size is 0 0 0, the ProximitySensor should be disabled, and not generate any events. Therefore, even at the second Viewpoint (located at the center of the ProximitySensor), the ProximitySensor will not activate, and the Sphere should not change color.'/>

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.

PROX_SENSOR ProximitySensor 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 set_diffuseColor SFColor
PROX_SENSOR ProximitySensor 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 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! 😀
