default_visibilitysensor.x3d (X3dToXhtml listing)

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.

VISIB_SENSOR VisibilitySensor isActive SFBool	→ ROUTE event to (1)	TIME TimeSensor enabled SFBool	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
VISIB_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
VISIB_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

16	<meta name='description' content='Test default VisibilitySensor properties. A Sphere geometry has an associated VisibilitySensor in front of it, at point 0 0 0. The default ViewPoint is at point 0 0 10, looking down the -Z axis. Because the bounding box, with dimensions 0 0 0 is in direct sight, an isActive event is generated by the enabled VisibilitySensor node. In addition, an enterTime event is generated, which is routed to a TimeSensor node to start an animation of the Sphere geometry. When the user moves to the second viewpoint, behind the bounding box, at point 0 0 -10, an isActive=FALSe event is generated, along with an exitTime event, and the Sphere ceases to change color.'/>
