Event Graph ROUTE Table entries with 6 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)	HUD Transform rotation SFRotation
HereIAm ProximitySensor position_changed SFVec3f	→ ROUTE event to (1)	HUD Transform translation SFVec3f
HereIAm ProximitySensor position_changed SFVec3f	→ ROUTE event to (1)	CnvText Script position SFVec3f	then	CnvText Script orientationText MFString	→ ROUTE event to (2)	BottomTextLine Text string MFString
			then	CnvText Script positionText MFString	→ ROUTE event to (2)	TopTextLine Text string MFString
HereIAm ProximitySensor orientation_changed SFRotation	→ ROUTE event to (1)	CnvText Script orientation SFRotation	then	CnvText Script orientationText MFString	→ ROUTE event to (2)	BottomTextLine Text string MFString
			then	CnvText Script positionText MFString	→ ROUTE event to (2)	TopTextLine Text string MFString

Additional guidance on X3D animation can be found in the 10-Step Animation Design Process and Event Tracing hint sheets. Have fun with X3D! 😀
