Event Graph ROUTE Table with 0 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.

ProtoInstance HeadsUpDisplay |
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. |
