Research And Design Of Virtual Laboratory For The Principle Of Computer Base On VRML

Virtual Laboratory is one of the hot research problems of modern education experiment reform. According to the problems of VRML of insufficient authenticity and diversity, this paper brings the detail level algorithm and image texture model in using VRML to construct principle of computer form virtual laboratory model, and improves the Event-Handling Mechanism of VRML. Based on the researching on the methods of Constructing and interacting the virtual model of principle of computer, this paper optimizes the virtual model through file compression and reducing redundant characters, accomplishes the prototype system development. As for its experimental results, this paper makes use of composition of unit of Principle of Computer, Carry control, and Shift operation to test the system, then analyses the experimental results reliably. The major structure of present paper are as follows:1. The application of association detail level algorithm and image texture in constructing virtual model. They facilitate the straightening out of problems which show the details of constructing virtual model. When we take the Image texture model into the showing of High-level details of the model, actual application of virtual experiment systems show that the heightened sense of realism of model is improved. The immersion of system has achieved good results2. This paper optimizes the virtual model through file compression and reducing redundant characters, design a load model to connecting the monitor. They facilitate the straightening out of problems which render complex model with slow speed. It has a good effect to optimize the whole system.3. This paper has established the virtual laboratory of Principle of Computer based on VRML, and it makes use of three experiments about composition of unit, Carry control, and Shift operation to check maneuverability of the Virtual system. The experimental results indicate that we can get the expected data accurately. The virtual laboratory of Principle of Computer based on VRML can substitute the traditional laboratory, it is used to provide a new method for teaching reform of experiment of Principle of Computer.
