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)

ColumnPath
OrientationInterpolator
set_fraction
SFFloat

then

ColumnPath
OrientationInterpolator
value_changed
SFRotation

→
ROUTE
event to
(2)

Column
Transform
set_rotation
SFRotation

Additional guidance on X3D animation can be found in the 10-Step Animation Design Process and Event Tracing hint sheets. Have fun with X3D! 😀
