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.

T

I
OrientationInterpolator
set_fraction

ProtoInstance
Rotor 		No ROUTE connection found for output events from this node.
This ProtoInstance contains SFNode/MFNode fieldValue declaration with
direct access to other nodes, and thus has potential to produce run-time animation.

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