A Switch node is the parent of a NormalInterpolator node that changes the illumination of an IndexedFaceSet geometry. The NormalInterpolator has been "switched out" by setting the whichChoice field to -1. The result should be, the NormalInterpolator should continue send and receive events, and animate the illumination of the geometry such that light appears to move horizontally, then vertically around the box shaped IndexedFaceSet.'/>

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.
