摘要
探讨了工程图学网络教学系统的实现方案及开发的关键技术。为使系统具有良好的通用性和可扩展性,提出了“动态网站+数据库+虚拟现实+实体设计”的新方案,综合发挥了各种开发工具的优势;设计了基于B/S模式的网络教学系统结构模型,提高了系统更新和维护的方便性;深入研究了虚拟现实建模语言(VRML)在开发工程图学网络教学系统中的应用,建立了虚拟现实模型库,克服了同类教学系统中动画不能实时控制及动画文件过大的问题。
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.
