Research on Key Technologies of System Development of Engineering Graphics Virtual Experiment

With regard to the characteristics of engineering graphics virtual experiments,three needs in the virtual laboratory system＇s control of the virtual models are identified as： to obtain the data of model status,to acquire the data of model geometry and to generate the model.Several key technologies in the realization of model control,such as the technology of controlling VRML by Java,the technology of VRML model data acquisition and the technology of virtual model creating.are studied in the paper.The experiments verify the feasibility and effectiveness of these methods.These key technologies solve the most difficult problems in virtual experiment system,and provide the basis for developing other virtual system based on VRML.
