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.

Rotator SphereSensor rotation_changed SFRotation	→ ROUTE event to (1)	SharkRotation Transform rotation SFRotation
Rotator SphereSensor rotation_changed SFRotation	→ ROUTE event to (1)	UserInterfaceRotation Transform rotation SFRotation

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