摘　　要：Intra3D是基于 Open GL的交互式三维图形软件开发工具 ,其核心是集成了场景数据结构、图形对象、三维交互算法和图形用户界面的 C+ +类库与 COM对象库 .论述了 Intra3D可复用软构件库的体系结构和三维交互设计 .软构件库分为基础对象与函数、图形对象、场景图与节点和绘制与交互 4层 .三维交互着重论述节点的图形变换、鼠标跟踪球算法和Intra3D is an interactive 3D toolkit based on OpenGL. Its C++ class library and COM library integrates scene data structure, graphical objects, 3D interaction algorithms and graphical user interface. The architecture design and 3D interaction of intra3D reusable library are discussed in this paper. The library is composed of four layers: ‘basic objects and functions’, ‘graphical objects’, ‘scene graph and nodes’ and ‘rendering and interaction’. The design of 3D interaction is focused on ‘scene node transformation’, ‘mouse trackball algorithm’ and ‘3D user interface’.
