Abstract
VRML is mainly used to make 3D user interface and to control dynamic display in real-time state. Java is responsible for correspondence between Web browser and VRML scene, also for linkage with other information system section. Paper first introduced default VRMLpsilas invisible 3D viewerpsilas avatar modeling. Then mainly discussed VRML and Java combination, including VRMLpsilas deficiency in creating real-time data input and output for peripheral equipment; adopting EAI to create Java Applet for the purpose of real-time data correspondence between external application program and VRML scene nodes. EAI technology strategies, EAI operation mechanism, EAI four kinds of possible accessing type and its event transmit mechanism etc. contents are detailed formulated. Finally paper described a typical VRML avatar PROTO definition specification and its concrete avatar citation application example.
