Design and Development of Virtual Laboratory Based on Vrml

With the rapid development and wide application of Virtual Reality technology, it is possible to use the virtual laboratory equipment to experiment.Design and development of virtual laboratory,provides a way to save resources,convenient and flexible experimental environment for the experimental teaching.The paper analyzes the structure of computer composition principle laboratory and the characteristics of experiments,proposed the design proposal of the virtual laboratory,and its implementation are described.The scenarios of virtual laboratory is developed mainly in VRML language,and the realization of the virtual experiments uses VRML and the JavaScript language programming.
