PhysicsBasedExplosionPrototype.x3d (X3dToXhtml listing)

Event Graph ROUTE Table entries with 12 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.
