multi_sensor.x3d (X3dToXhtml listing)

Event Graph ROUTE Table entries with 8 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_SENSOR1 ProximitySensor enterTime SFTime	→ ROUTE event to (1)	TIME1 TimeSensor startTime SFTime	then	TIME1 TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP_COLOR1 ColorInterpolator set_fraction SFFloat	then	INTERP_COLOR1 ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	COLOR1 Material diffuseColor SFColor
PROX_SENSOR1 ProximitySensor exitTime SFTime	→ ROUTE event to (1)	TIME1 TimeSensor stopTime SFTime	then	TIME1 TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP_COLOR1 ColorInterpolator set_fraction SFFloat	then	INTERP_COLOR1 ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	COLOR1 Material diffuseColor SFColor

PROX_SENSOR2 ProximitySensor enterTime SFTime	→ ROUTE event to (1)	TIME2 TimeSensor startTime SFTime	then	TIME2 TimeSensor fraction_changed SFFloat	→ ROUTE event to (2)	INTERP_COLOR2 ColorInterpolator set_fraction SFFloat	then	INTERP_COLOR2 ColorInterpolator value_changed SFColor	→ ROUTE event to (3)	COLOR2 Material diffuseColor SFColor

16	<meta name='description' content='Two unique (not instances of) ProximitySensor node are associated with two unique Sphere geometry. The left ProximitySensor (whose bounding box is represented by the IndexedLineSet box), should route its events to change the Color of the left Sphere from white to blue when the viewers avatar enters its bounding box. The right ProximitySensor should change the color of the right Sphere from white to red when activated. The central "overlapping" area, when entered by the viewers avatar, should concurrently activate both ProximitySensors, and generate seperate events for both of them. The result is, both Spheres should change from white to their respective colors of blue (left) and red (right).'/>
