The Online Studying System Of Computer Graphic Based On VML

With the development of computer technology, computer graphic is a branch of one the most active science. Today computer graphic has been deeply rooted in all aspects of modern society and is widely used in animation, scientific visualization, CAD/CAM, video entertainment, and other fields. This study is based on MVC design mode and thought the researching in VML and geometric graphic algorithm a system on Computer Graphic Online studying was developed. VML (the Markup Language of the Vector) was released by Microsoft company in 1999.It`s a marking program language like a paintor on IE and only can be carried out by IE5.0 as well as up of 5.0 edition. You can draw sketchs that you want and get the sketch dynamic result.Finally through the deep study and research of the MVC design pattern and struts framework, this thesis expouds how to use struts framework to resolve the questions by optimizing the Web development framework and compiling code builder. An example based on the online learning system of the computor graphic introduced to illustrate the process to build an n-tier-framework-based system with the help of the Struts framework . In this case VML language, Java language,Javascript language,div+css language as well as JSP language were studied deeply .And in this case the developing terrace of Dreamweaver + Myeclipse + tomcat + JDK+SQLserver can be laborated detailedly and distinction between description logic and business logic is made possible within the MVC design pattern, which means better flexibility and easier management in the exploration of a system. Results show that this new framework helps to increase work efficiency in exploration. Meanwhile, expansibility and maintainability of the system within this framework are also satisfactory.
