Research And Development. "engineering Drawing" Web-based Teaching Site

Web Teaching System is the combination of teaching content with teaching activities of some discipline through Web.Based on wide study and a great deal of bibliography, this paper comprehensively study and conclude the development process of constructing Web courses of these years and the characteristics of main remote teaching system of both domestic and abroad; Meanwhile this paper analyze the main disadvantage of current remote teaching system and its future development and tendency. Based on the analysis and conclusion of systemization web and application of the course of engineering drawing, this system adopt Browser/Server (B/S) mode and design idea. I carry on the general design of this teaching Web on engineering drawing, This teaching web choose Microsoft Access 2003 as its background database ;AutoCAD 2004 as its graphics process flat under Web environment which is popularly used by engineers and technicians; powerful DreamweaverMX as the software which is used to develop the web site; the newest version of 3DSMAX which is used to make 3D animation and is developed by famous Autodesk to render images; It also make use of JavaScript and VRML so as to make 3D virtual models made by VRML more lovely. Finally, this system study following key technologies: ASP IIS . personnel authority management based on roles.Engineering drawing course has images and graphics as its main characteristics. The technology ASP adopted by this web site make lovely dynamic interactive web home page more easy. Especially this web site adopt interaction technology provided by VRML, so that it overcome commonly-used simple fixed-route animation and complement real-time interaction animation between human and computer. Created by those technologies mentioned above, the virtual scene can significantly provoke students' interest in study. VRML is web-oriented, so its important traits is real-time rendering, its advantage is that it can avoid transmitting big volume video images frame by frame. Rather, it transmit small volume WRL files, that's to say, it only transmit model which describe scene and the comeout of animation is real-time rendered at local host. Thus it decrease the transmitting volume of image files and make the image quality better, and it's very important in transmitting on Web.Take advantage of all technologies mentioned above, I try to develop some sub-=system...
