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.

CLOCK
TimeSensor
fraction_changed
SFFloat

ROUTE
event to
(1)
PI
PositionInterpolator
set_fraction
SFFloat
then

value_changed
SFVec3f

ROUTE
