The third index of the attenuation field is set to 0.1, which should cause the attenuation to decrease inversively proportional to the square of the distance from the light. The light brightness should decrease rapidly as the objects move away from the light. The ambientIntensity and the intensity are set to 1 for all geometry.'/>

Event Graph ROUTE Table entries with 10 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.
