摘要随着计算机图形技术、可视化技术的发展，我们可以使用计算机来精确再现现实世界绚丽多彩的三维物体，并充分发挥自身的创造性思维，通过人机交互来模拟、改造现实世界，这就是虚拟现实技术。

军事指挥员通过这种技术可以模拟战场进行军事推演；建筑师可以直接设计出宏伟的高楼大厦；而我们只要上网就能游览名胜古迹等。而图形编辑就是虚拟现实技术的一个重要的部分,OpenGL就是近几年发展起来的一个性能卓越的图形标准, OpenGL是功能强大的开放式图形库,它已经成为一个工业标准的计算机图形软件开发接口，并广泛应用于游戏开发、流体力学、建筑、产品设计、医学、地球科学等领域。虽然微软有自己的三维编程开发工具DirectX，但它也提供OpenGL图形标准，因此，OpenGL在计算机图形技术中广泛应用。  49799

论文运用OpenGL工具创建小型CAD系统平台，平台实现通过VC++建立基本框架，运用OpenGL函数库来实现平台各部分功能，开发小型CAD系统，可以绘制各类基本图形，并能通过OpenGL技术调用显示三维图形。

ABSTRACT With the development of computer graphics and visualization technology, we can use the computer to accurately represent the real world of colorful three-dimensional objects, and give full play to their creative thinking, through the human-computer interaction simulation, transform the real world, this is by far the most popular virtual reality technology. 

Through this technology, the architect can direct design the beautiful building model; Military commanders can simulate the battlefield military exercise; the web cam could excurse museum, scenic spot and historic resort being confined at home and so on. And the most important part of virtual reality technology is graphical editor. OpenGL is a powerful open graphics library. And OpenGL is developed in recent years, a high performance 3D graphics standard. It has become an industry standard of computer graphic interface, software development and is widely used in game development, architecture, product design, medical science, earth science, fluid mechanics, etc. While Microsoft has its own 3D programming DirectX development tool, but it also provides the OpenGL graphics standards, therefore, OpenGL is widely used in the computer. 

The design using OpenGL tools to create small CAD system platform, platform implementation through VC++ to establish the basic framework, using the OpenGL library to build platform for all parts of function, the development of small CAD system, can draw all kinds of basic graphics, and can display the 3D graphics with OpenGL technology call.
