Event-utility nodes allow conversion and connection of different data types via ROUTEs, while
Script nodes allow authors to write their own event-handling code for special scene capabilities.
Event utility nodes simplify data-type conversion of events when producing animation chains between nodes.
The quick-reference sheet
X3D Event Utility Nodes: Field Event Diagrams
illustrates the functionality of the event utility nodes.
These nodes receive and pass values that are sent via
Authors can add
declarations that define
