| We developped web virtual digital logic circuit laboratory base on VRML with the aid of the modern communication, computer and virtual reality technique.First,The paper introduced a virtual reality technique and it is in the application in the virtual laboratory, and pass to a few analysis with technical keys that sets up virtual laboratory, make sure this system development want to use of technique - VRML.Second, at to virtual laboratory system analytical foundation up, put forward setting up the function request,function request and the animation design request of this virtual laboratory system, and designed a net up the mold piece of the virtual laboratory system structure.Give set up a 3D experiment a field a view and hand over with each other the type conjecture an experiment of concrete carry out a method.End, made use of Dreaweaver to set up numerical logic electric circuit the web page structure of the virtual laboratory, and release it through internet.The main characteristics of this system: First, there is intensively actual feeling in mutual interface. This virtual laboratory provides a three dimensionality experiment environment, which has the true feel of participating in scene and the virtual character, and the user can choice an experiment way for them, thus this system is advanced and applied. Second, to extend is very easy. The design process of the virtual laboratory system can conclude a general manner so can exploit other virtual laboratories. Third, there is better mutual trait. This virtual laboratory provides the mutual and dynamic contents and models among the users and virtual environment, the users can control and operate experimental process in real time, there is a lot of advantage in operability and participating, it can exercises the operation ability of users. |
