Event Graph ROUTE Table entries 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.

HereIAm ProximitySensor orientation_changed SFRotation	→ ROUTE event to (1)	HudContainer Transform rotation SFRotation
HereIAm ProximitySensor position_changed SFVec3f	→ ROUTE event to (1)	HudContainer Transform translation SFVec3f
