摘　　要：现有的WIMP风格的三维设计软件需要用户对点、线、面通过复杂的造型和交互才能组合、拼装成符合现实需求的三维实体,不利于普通用户的掌握和应用。结合Qt平台及Irrlicht三维渲染引擎,采用C++编程可以实现二维草图和三维场景的集成与交互,从而通过绘制二维草图创建三维虚拟场景。该系统可简便、直观地创建处于同一水平面的三维虚拟场景,适用于普通用户室内设备管理和场景展示。Using the traditional 3D softwares based on WIMP to create 3D scenes, users have to be professional e- nough to assemble the geometrical elements, such as points, lines and planes, into complex 3 D entities for practical needs. In order to satisfy the ordinary users, a mechanism combined a UI framework （Qt） and a 3D engine （Irrli- cht） is provided to produce virtual scenes only by drawing 2D sketches with computer input devices. This system is written in C ＋ ＋ and allows the 3D scenes to be updated in real - time as the corresponding 2D sketches are changed. It can be easily and intuitively used to create 3D scenes on the same plane, which can be applied to in- door equipment management and display for common users.
