摘　　要：从功能定位入手,介绍了使用Visual C++基于DirectX SDK设计并实现一个视景仿真软件平台的思路和方法。该平台采用了"基于共用内核的双平台"总体架构,建立了可重用的框架和二次开发机制,采用"功能实体-集合管理-用户界面"三层设计模式,提高了代码重用度,在降低问题复杂度的同时提高了开发效率。该视景仿真平台建立了可扩展的可视对象管理机制、实现了中小规模场景的显示优化和高效地形匹配计算、实现了基于粒子系统的烟云、雨雪、爆炸、燃烧等特殊效果的逼真显示以及对于关键帧动画的支持。最后介绍了应用案例。The ideas and method about the realization of a scene simulation platform using Visual C＋＋ and Direct SDK were introduced.The platform adopted the overall structure of ＂twin platform based on the shared core＂,and reusable framework and mechanism for the further development were founded.Three-tier design pattern of ＂function entity,collection management and user interface＂ improved code reusing.So the complexity of the problem was reduced,and the software development efficiency was improved.In this scene simulation platform,the management mechanism of extensible visual object was established,the display optimization of medium or small scene and rapid terrain-matching were realized,the functions of particle system-based special effects about rain,snow,smog and blast,etc,and creating,editing,playing and saving key frame animation were achieved.Finally,the applied example was researched.
