Therefore, it should translate appropriately with its parents Transformation parameters (-100 -100 100). Viewpoints in the root Transform node are offset by -100 -100 100, and should create orthographic (perfect 90 degree) views for all viewpoints. All inside views should appear identical. All outside views should appear identical. The Sphere geometry should turn color from red to blue for "inside" views.'/>

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 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 diffuseColor SFColor
