Research On Virtual Simulation Experiment Platform Of Computer Composition Principle

Nowadays,with the rapid development of modern information technology,to solve the shortcomings of traditional experimental teaching,a large of high education institutions have launched a new type of online virtual experiment teaching model.Virtual experiment is a kind of simulation experiment which is aid of computer simulation technology and multimedia technology.It provides an effective solution to solve the problems in the traditional experimental teaching,such as the old experimental instruments,the lack of funds and the limited experimental time.But the application of the virtual experiment is not very wide,it only confined to part of the universities,and,most of the virtual experiment is only teaching demonstration experiment,its interactive design cannot meet the need of the experimenters and it cannot fundamentally solve the shortcomings of traditional experimental teaching.Therefore,this paper based on virtual experiment teaching situation,combined with the related theory of virtual experiment,through the overall design of the virtual experiment platform,research a virtual simulation experiment platform which is based on the principle computer composition principle.Firstly,from the virtual experimental research background,this paper analyzes the main research status of the virtual experiment at home and abroad,then it detailed introduces the classification of the virtual experiment and the characteristics of the virtual experiment;on this basis,this paper introduces the relevant technology which is used in the process of constructing virtual experiment.Then introduces the virtual reality modeling language VRML,briefly introduces the overview of VRML,and detailed introduces the working principle of VRML and its characteristics,then introduces the shape node of the VRML,analyzes the interactive mode of the VRML,on this basis,mainly introduces how to construct a simple scene model by VRML and how to construct a complex experiment model by 3Ds Max,and then introduces the optimization method of the model;then,combined with the theory of teaching knowledge and VRML technology.Using the JavaScript scripting language,detailed researches the interaction design of the virtual experiment,and then introduces two experiments's logical test,one is principle without carry bit logical or operation and the other is without carry adder operation;finally,briefly introduces the online publishing of the virtual experiment.
