| Abstract: | The solution and key techniques for building a network teaching system on engineering graphics are discussed in this paper.To make the system more useful and expansible,a new solution has been devised to take advantages of various development tools.A structure model based on B/S has been designed to improve the convenience of update and maintenance.The application of virtual reality modeling language (VRML) in developing teaching system has been studied and a model library based on VR has been built to overcome the problems that cartoons in the model library can not be controlled in real-time and each cartoon takes up a large number of hard disc space. |
