| 摘要: |
| 本文介绍了作者设计并实现的一个面向对象的计算机图形系统．由于系统采用了面向对象的系统设计思想，使用户可以通过高层概念来设计对象模型，且模型设计直观、自然，避免了在传统图形系统中，要求用户使用低层图形概念进行建模．同时也保证了系统的易扩充性和易复用性，使本系统真正成为图形应用支持系统．用户只要加入适当的领域知识，本系统很容易扩充为一个面向领域的图形系统． |

| Abstract: |
| This paper introduced all object—oriented graphics support system．The authors used object—oriented concept to design this system，so that one can design graphical application model at high level of abstraction and translate his meaning into a model maturely．The system is designed to be easily extensible and reuse．By adding some special knowledge about some area，the user can tailor the system into a more special one． |
| Key words: Object,object—oriented,computer graphics system,constraint． |
