基于Web的机械制图虚拟模型库的构建

Construction of Virtual Model Library for Mechanical Drawing Course Based on Web

针对当前机械制图课程教学中存在的网络课件相对滞后的缺陷,从教学实际需要出发,根据课程的主要内容,自主研发了一个网络教学课件。其中虚拟模型库利用VRML构建,具有动态性、交互性、低带宽网络传输等特性,在实际教学中取得了良好的效果。

Because of the defects and the insufficiency of Web-based CAI in the present teaching of Mechanical Drawing, a CAI for Mechanical Drawing course based on Web is developed, which takes the main teaching contents as CAT＇s target to meet the needs of Mechanical Drawing instruction. The virtual model library are constructed with VRML, which has a lot of advantages such as dynamical character, interactive character and low band transmission on Web, and so on. The better effects have got in the practice of teaching.
