Event Graph ROUTE Table with 2 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.

TIME
TimeSensor
fraction_changed
SFFloat

ROUTE
event to
(1)
SCALAR_INTERPOLATOR
ScalarInterpolator
set_fraction
SFFloat
then
 
 
 
SCALAR_INTERPOLATOR
ScalarInterpolator
value_changed
SFFloat

ROUTE
event to
(2)
LIGHT
SpotLight
intensity
SFFloat
