LoadSensorKelpForestMain.x3d (X3D Model Documentation)

🔖 Event Graph ROUTE Table entries with 14 ROUTE connections, showing X3D event-model relationships for this scene.

Each row with a ROUTE statement shows an event cascade that may occur during a single timestamp interval between frame renderings, performed as part of the X3D execution model.

ViewPositionOrientation

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