An Extension of Network Communication in X3D for Remote Monitor and Control

X3D can be used in industrial monitor and control applications. There exist frequent vast data interactions in these applications. Standard scene access interface in X3D can't right meet it. And X3D also supports the criterion extension oriented to specified markets. This paper presents a suit of communication nodes. Based on direct-output-event mechanism and standardized protocol data, new nodes can implement a data-driven batch events transfer mode. The executing model, function model and data protocol of extended nodes are described. And among them, the net communication node is discussed as emphasis. Finally, the implementation and application for remote monitor and control based on it are also introduced.
