The result should be, the CoordinateInterpolator should continue send and receive events, and animate the shape of the geometry. The geometry should stretch along the X, Y and Z axex.'/>

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.
