The Research And Implementation Of Virtual Lab System Based On WWW

On the basis of the study of remote education system, and aim at the weakness of its experiment link, the paper designs and realizes a virtue experiment system adapt to remote network education using virtue reality technique.From the collectivity design of the virtual experiment system based on internet, the paper proposes the composing module. From the study of the construction of virtue scene and the interactive technique of the user to the virtual scene, the paper proposes the modeling sort and modeling method of the system. In the movement modeling, the paper proposes a method used as describing the phenomenon of object movement, that is, using texture mapping method to describe the collision response of object. On the basis of using the physics experiment as study object, builds the modeling of a few of typical physical phenomenon, and proposes the arithmetic of collision measure. At the same time, on the basis of studying the interactive thoroughly, the paper proposes that make VRML and JAVA band together, fulfills the user's interactive appeal to the virtual experiment.The virtual experiment system make the three- dimension modeling language VRML as the core, using JAVA, javascript and WEB technique synthetically, it has doughtily advanced capability, practicability, and multi-flat roof ability and so on, it makes up the insufficiency of the experiment curricula in the network education, and it is a breakthrough of traditional remote network education, and has a certain extent utility value.
